IPS-E-PR-730(1)

IPS-E-PR-730(1) FOREWORD The Iranian Petroleum Standards (IPS) reflect the views of the Iranian Ministry of Petroleum and are intended for use in the oil and gas production facilities, oil refineries, chemical and petrochemical plants, gas handling and processing installations and other such facilities. IPS is based on internationally acceptable standards and includes selections from the items stipulated in the referenced standards. They are also supplemented by additional requirements and/or modifications based on the experience acquired by the Iranian Petroleum Industry and the local market availability. The options which are not specified in the text of the standards are itemized in data sheet/s, so that, the user can select his appropriate preferences therein. The IPS standards are therefore expected to be sufficiently flexible so that the users can adapt these standards to their requirements. However, they may not cover every requirement of each project. For such cases, an addendum to IPS Standard shall be prepared by the user which elaborates the particular requirements of the user. This addendum together with the relevant IPS shall form the job specification for the specific project or work. The IPS is reviewed and up-dated approximately every five years. Each standards are subject to amendment or withdrawal, if required, thus the latest edition of IPS shall be applicable The users of IPS are therefore requested to send their views and comments, including any addendum prepared for particular cases to the following address. These comments and recommendations will be reviewed by the relevant technical committee and in case of approval will be incorporated in the next revision of the standard.

Some degree of removal is also accomplished by conventional secondary treatment. Waste waters containing volatile organic constituents may be treated by air striping or by carbon adsorption. Small concentrations of specific contaminants may be removed by ion exchange.

If emulsified or dissolved oil is present, an oil-water separator will not be able to remove it, and additional downstream treatment will be required. A principal function of the oil-water separator is to remove gross quantities of free oil before future treatment. In this capacity, the oil-water separator protects more sensitive downstream treatment processes from excessive amounts of oil. Parallel-plate separators require less space than do conventional oil-water separators and are theoretically capable of achieving lower concentrations of effluent oil. In some applications, the oil-water separator is provided as a protective device for containment of spills and leaks (e.g., on once-through cooling water). ‫آب‬-‫ﺑﺎﻳﺪ ﺗﺎﻛﻴﺪ ﻛﺮد ﻛﻪ ﻫﺮﮔﺎه ﻓﻘﻂ از ﺟﺪاﻛﻨﻨﺪه ﻫﺎي روﻏﻦ‬ ‫ ﻣﻘﺪار روﻏﻦ ﻫﺎي ﻣﻌﻠﻖ و ﺣﻞ ﺷﺪه ﻣﻮﺟﻮد در‬،‫اﺳﺘﻔﺎده ﺷﻮد‬ ‫ زﻳﺮا اﻳﻦ ﻗﺒﻴﻞ روﻏﻦ‬،‫ﺟﺮﻳﺎن ﭘﺴﺎب ﺑﺎﻳﺪ ﺑﻪ دﻗﺖ ﺗﻌﻴﻴﻦ ﮔﺮدﻧﺪ‬ It should be stressed that whenever an oil-water separator is considered for an application where it must stand alone, the amount of emulsified and dissolved oils in the waste-water stream must be properly quantified, because these oils will not 48 Feb 2010/ 1388 ‫ﺑﻬﻤﻦ‬ IPS-E-PR-730(1) . ‫ﻫﺎ ﺑﺎ ﺟﺪاﻛﻨﻨﺪه ﻫﺎ ﺟﺪاﺳﺎزي ﻧﺨﻮاﻫﻨﺪ ﺷﺪ‬ be removed by the separators. ‫ ﻣﻼﺣﻈﺎت ﻛﻠﻲ ﻣﺮﺑﻮط ﺑﻪ ﻃﺮاﺣﻲ ﺟﺪا ﻛﻨﻨﺪه‬3-5-7 7.5.3 Oil-Water separators general design considerations ‫آب‬-‫ﻫﺎي روﻏﻦ‬ The following requirements shall be taken into consideration in the design stage. .‫در ﻣﺮﺣﻠﻪ ﻃﺮاﺣﻲ اﻟﺰاﻣﺎت زﻳﺮ ﺑﺎﻳﺪ در ﻧﻈﺮ ﮔﺮﻓﺘﻪ ﺷﻮد‬ : ‫اﻟﻒ( ﻣﻜﺎن‬ a) Location: - Safety distance; - Access from the road; - Prevailing wind (when applicable); - Possible future extensions. ‫ﻓﺎﺻﻠﻪ اﻳﻤﻨﻲ ؛‬ ‫دﺳﺘﺮﺳﻲ از ﻃﺮﻳﻖ ﺟﺎده ؛‬ ‫ﺑﺎد ﻏﺎﻟﺐ ) ﻫﺮﮔﺎه ﻗﺎﺑﻞ ﻛﺎرﺑﺮد ﺑﺎﺷﺪ( ؛‬ - . ‫ﺗﻮﺳﻌﻪ ﻫﺎي اﺣﺘﻤﺎﻟﻲ ﺑﻌﺪي‬ - :‫ب( ﻋﻤﻠﻜﺮد‬ b) Function: - Two way access /escape for operator; - hand railing and grating; - Proper ventilation for depressed locations; - Lamp posts; - Surface drainage; - kerbs around pump foundations; - Signboard instructions; number with Unit ‫ﻧﺮده و ﺳﻄﺢ ﻣﺸﺒﻚ‬ - ‫ﺗﻬﻮﻳﻪ ﻣﻨﺎﺳﺐ ﺑﺮاي ﻣﻜﺎن ﻫﺎي ﮔﻮد؛‬ - ‫ﺗﻴﺮﻫﺎي ﭼﺮاغ ﺑﺮق ؛‬ - ‫ﺗﺨﻠﻴﻪ ﺳﻄﺤﻲ ؛‬ - ‫ﺟﺪاول اﻃﺮاف ﻓﻮﻧﺪاﺳﻴﻮن ﺗﻠﻤﺒﻪ ؛‬ - ‫ ﻳﺎ ﺧﻨﻚ ﺳﺎزي آب‬/‫ﻣﻨﺒﻊ آب ﺑﺮاي ﺷﺴﺘﺸﻮ و‬ ‫ﺑﻨﺪ ﺗﻠﻤﺒﻪ ؛‬ - Water supply for flushing and/or pump seal cooling; for - ‫ ﺗﻠﻤﺒﻪ ﻫﺎ و‬،‫دﺳﺘﺮﺳﻲ آﺳﺎن ﺑﻪ روﻏﻦ ﮔﻴﺮﻫﺎ‬ ‫ﺻﺎﻓﻲ ﻫﺎ؛‬ - Easy access to skimmers, pumps and filters; - Maintenance access truck/mobile crane; ‫ﻓﺮار ﺑﺮاي ﻣﺘﺼﺪي واﺣﺪ ؛‬/‫دﺳﺘﺮﺳﻲ دو ﻃﺮﻓﻪ‬ ‫دﺳﺘﺮﺳﻲ ﺗﻌﻤﻴﺮاﺗﻲ ﺑﺮاي ﻛﺎﻣﻴﻮن ﺧﻼ ﻳﺎ ﺑﺎﻻﺑﺮ‬ ‫ﺳﻴﺎر ؛‬ ‫ﺗﺎﺑﻠﻮي اﻋﻼﻧﺎت ﺑﺎ ﺷﻤﺎره واﺣﺪ و دﺳﺘﻮراﻟﻌﻤﻞ ﻫﺎ؛‬ - vacuum and ‫آژﻳﺮ ﻫﺸﺪار دﻫﻨﺪه ﺳﻄﺢ ﺑﺎﻻ در ﭼﺎﻫﻚ ﻫﺎي‬ ‫ﺟﻤﻊ آوري روﻏﻦ در اﺗﺎق ﻛﻨﺘﺮل ؛‬ . ‫ﺣﻠﻘﻪ ﻫﺎي ﺣﺮارﺗﻲ در ﺷﺮاﻳﻂ ﻫﻮاي ﺳﺮد‬ - - High level alarm in oil collecting sumps in the control room; - Heating coils in cold climate conditions. :‫ج ( ﻓﺎﺻﻠﻪ ﻫﺎي اﻳﻤﻨﻲ‬ c) Safety distances: - Distance to the edge of public roads: 30 m - Distance to the edge of main roads: 15 m - Distance to a fixed source of ignition: 15 m. ‫ ﻣﺘﺮ ؛‬30 : ‫ﻓﺎﺻﻠﻪ ﺑﺎ ﺣﺎﺷﻴﻪ ﺟﺎده ﻫﺎي ﻋﻤﻮﻣﻲ‬ ‫ ﻣﺘﺮ ؛‬15 : ‫ﻓﺎﺻﻠﻪ ﺑﺎ ﺣﺎﺷﻴﻪ ﺟﺎده ﻫﺎي اﺻﻠﻲ‬ - . ‫ ﻣﺘﺮ‬15 : ‫ﻓﺎﺻﻠﻪ ﺑﺎ ﻣﻨﺒﻊ ﺛﺎﺑﺖ ﺟﺮﻗﻪ‬ - :‫د ( ﻛﻨﺘﺮل آﻟﻮدﮔﻲ ﻫﻮا‬ d) Air pollution control: ‫در ﺻﻮرت درﺧﻮاﺳﺖ ﺷﺮﻛﺖ و ﻳﺎ اﻟﺰام ﻣﻘﺮرات زﻳﺴﺖ‬ ‫ ﺑﺎﻳﺪ اﺑﺰار ﻛﻨﺘﺮل ﻣﻮﺛﺮي ﺑﺮاي ﺑﻪ ﺣﺪاﻗﻞ رﺳﺎﻧﺪن‬،‫ﻣﺤﻴﻄﻲ‬ ‫زﻳﺎن ﻫﺎﻳﻲ ﻛﻪ ﻫﻴﺪروﻛﺮﺑﻦﻫﺎ و دﻳﮕﺮ آﻻﻳﻨﺪه ﻫﺎﻳﻲ ﻣﺎﻧﻨﺪ‬ Effective means of control to be instituted to minimize losses of hydrocarbon and other contaminants such as sulfur Compounds to the atmosphere from the large exposed 49 Feb 2010/ 1388 ‫ﺑﻬﻤﻦ‬ IPS-E-PR-730(1) ‫ﺗﺮﻛﻴﺒﺎت ﮔﻮﮔﺮدي ﻛﻪ ﺣﺎﺻﻞ از ﺑﺨﺶ ﺳﻄﺤﻲ وﺳﻴﻊ و‬ ‫ ﻓﺮاﻫﻢ‬،‫روﺑﺎز ﺟﺪاﻛﻨﻨﺪه ﻫﺎ ﻫﺴﺘﻨﺪ و ﺑﻪ ﺟﻮ وارد ﻣﻲ ﺷﻮﻧﺪ‬ .‫ﺷﻮد‬ ‫ﺑﺎ ﭘﻮﺷﺎﻧﺪن دﻫﺎﻧﻪﻫﺎي ﺟﻠﻮﻳﻲ ﻳﺎ ﺑﺨﺶﻫﺎي اوﻟﻴﻪ ﺟﺪا‬ ‫ ﻣﻲ ﺗﻮان اﻧﺘﺸﺎر‬،‫ﻛﻨﻨﺪه ﺑﻪ وﺳﻴﻠﻪ ﺳﻘﻒﻫﺎي ﺛﺎﺑﺖ ﻳﺎ ﺷﻨﺎور‬ ‫ ﺳﻘﻒ ﺑﺎﻳﺪ ﺗﺎ ﺣﺪ‬.‫ﻫﻴﺪروﻛﺮﺑﻦ ﻳﺎ آﻻﻳﻨﺪه ﻫﺎ را ﻛﻨﺘﺮل ﻛﺮد‬ .‫ﻣﻤﻜﻦ در ﺑﺮاﺑﺮ ﻋﺒﻮر ﺑﺨﺎر ﻣﺼﻮن ﺑﺎﺷﺪ‬ surface area of the separators if required by the Company and/or the Environmental Regulations.

The pipe shall be mounted horizontally across the entire length of the channel and shall be supported at both ends. The skimmer should be capable of being rotated both backward and forward over a range of 180 degrees so that, the separated oil that is collected between the skimmer and the oil-retention baffle can be recovered. The operation can be automatically by providing the proper control and actuating equipment, but in general, due to unsatisfactory results is not recommended. The size of the pipe diameters depends upon the capacity required, the variation in liquid level, and the distance which skimmings must travel within the pipe. Minimum pipe diameter shall be DN 250 (10 inch) which should be used for runs up to 12m, and larger pipe for longer runs. The slotted pipe can be rotated by a simple lever arrangement, by a rack and pinion linkage, by worm gear, or by motor. The worm gear arrangement is recommended, since it allows more precise skimming. Skimmer pipes shall be galvanized after fabrication.

The one-blade arrangement accomplishes this by adjusting the height of the blade to either oil level or channel bottom using a hoist or cam mechanism. The blade pivots on the underside of the bridge as height is changed. The two blade arrangement achieves the sequential movement of material by either of two means. During oil movement, the sludge blade can be moved out of the channel or it can be feathered parallel to the channel bottom. At the end of the downstream run, the oil moving blade is raised out of the water and the sludge-moving blade is properly positioned to move sludge upstream on the return trip. Surface travel is typically on the order of 0.6 m per minute and bottom travel is on the order of 0.3 m per minute. This device can span and operate in one or several channels. Operation can be manual or continuous; but is preferably automatic and actuated intermittently by a cycle time. ‫ﻟﺠﻦ داراي ﻣﺰاﻳﺎي‬/‫ﻧﻮع ﭘﻞ ﺳﻴﺎر دﺳﺘﮕﺎه اﻧﺘﻘﺎل روﻏﻦ‬ : ‫زﻳﺮ اﺳﺖ‬ The traveling bridge type oil/sludge moving device offers the following advantages: 64 Feb 2010/ 1388 ‫ﺑﻬﻤﻦ‬ IPS-E-PR-730(1) - The parts requiring lubrication are located above the water; ‫ ﺑﺨﺶ ﻫﺎﻳﻲ ﻛﻪ ﻧﻴﺎز ﺑﻪ روﻏﻦ ﻛﺎري دارﻧﺪ در‬‫ﻗﺴﻤﺖ ﺑﺎﻻي آب واﻗﻊ ﺷﺪه اﻧﺪ ؛‬ - It allows different travel speeds on the forward and reverse runs; ،‫ اﻳﻦ دﺳﺘﮕﺎه ﺣﺮﻛﺖ در ﻣﺴﻴﺮ ﻫﺎي ﺟﻠﻮ و ﻋﻜﺲ‬‫ﺑﺎ ﺳﺮﻋﺖ ﻫﺎي ﻣﺘﻔﺎوت را ﻣﻤﻜﻦ ﻣﻲ ﺳﺎزد؛‬ :‫ﻣﻌﺎﻳﺐ ﺑﻪ ﺻﻮرت زﻳﺮ اﺳﺖ‬ The disadvantages are as follows: ‫ ﮔﺮان ﺗﺮ از اﻧﻮاع دﻳﮕﺮ اﺳﺖ ؛‬- - More expensive than other types; ‫ ﺑﻪ ﻛﺎﺑﻞ ﻣﺘﺤﺮك ﺟﺮﻳﺎن ﺑﺮق ﻧﻴﺎز دارد؛ ﻣﻌﻤﻮﻻ ﻳﻚ‬‫ﺣﻠﻘﻪ ﻛﺎﺑﻞ ﻳﺎ ﻳﻚ ﺳﺎﻣﺎﻧﻪ ﺣﻠﻘﻮي از ﻛﺎﺑﻞ ﺣﻠﻘﻪ‬ ‫زده ﺷﺪه از ﻳﻚ ﺳﻴﻢ ﭘﺸﺘﻴﺒﺎن اﺳﺘﻔﺎده ﻣﻲ ﻛﻨﻨﺪ ؛‬ - Requires a movable power cable; usually either a cable reel or a festoon system using a cable looped from a supporting wire; ‫ ﭘﻮﺷﺶ دادن ﻛﺎﻧﺎل ﻫﺎ را ﻣﺸﻜﻞ ﻣﻲ ﻛﻨﺪ ؛‬- - complicates covering the channels; ‫ ﻃﺮح آن ﻣﺘﺪاول ﻧﻴﺴﺖ و در ﻛﺎﻧﺎل ﻫﺎي ﻣﺠﻬﺰ ﺑﻪ‬. ‫ﭘﻮﺷﺶ اﺳﺘﻔﺎده ﻧﺸﺪه اﺳﺖ‬ - the design is not common and has not been used on Units equipped with covers. ‫ﺗﻮﺻﻴﻪ ﻣﻲﺷﻮد وﻳﮋﮔﻲ ﻫﺎي ﻃﺮاﺣﻲ دﺳﺘﮕﺎه ﻧﻮع ﭘﻞ‬ : ‫ﺳﻴﺎر ﻣﻮارد ﻣﺸﺨﺼﻪ زﻳﺮ را در ﺑﺮﮔﻴﺮد‬ A design specification for a traveling bridge type device should include the following features: ‫ ﻓﺮاﻫﻢ ﻛﺮدن ﺟﺪاﺳﺎزي ﻋﺮﺿﻲ ﻛﺎﻣﻞ ؛‬- - Provide full width skimming; ‫ و‬، ‫ ﺿﺪ اﻧﻔﺠﺎر‬، ‫ ﻓﺮاﻫﻢ ﻛﺮدن ﻣﺤﺮك ﻫﺎي ﻣﺤﻔﻮظ‬‫ﺿﺪ ﺑﺎد و ﺑﺎران ؛‬ - Provide totally enclosed, explosionproof, weather-proof drivers; ‫ ﻓﺮاﻫﻢ ﻛﺮدن ﺣﻔﺎﻇﺖ در ﺑﺮاﺑﺮ ﺑﺎر زﻳﺎد ؛‬- - Provide overload protection; ‫ ﺟﻤﻊ ﻛﻨﻨﺪه ﺟﺮﻳﺎن رﻳﻞ ﺳﻮم ﻧﻮع ﺟﻤﻊ ﻛﻨﻨﺪه‬‫ﺟﺮﻳﺎن )ﺳﻮﻣﻴﻦ رﻳﻞ( ﻗﺎﺑﻞ ﻗﺒﻮل ﻧﻴﺴﺖ ؛‬ - The current collector (3rd. rail) type of power supply is not acceptable; ‫ ﻓﺮاﻫﻢ ﻛﺮدن اﻣﻜﺎﻧﺎﺗﻲ ﺑﺮاي ﺗﺮاز ﻛﺮدن ﺗﻴﻐﻪ ﻫﺎ ؛‬- - Provide facilities for leveling the blades; ‫ ﻓﺮاﻫﻢ ﻛﺮدن اﺑﺰارﻫﺎﻳﻲ ﺑﺮاي ﺑﻴﺮون آوردن ﺗﻴﻐﻪ ﻫﺎ‬. ‫از آب ﺑﺮاي ﺗﻌﻤﻴﺮات‬ - Provide means to raise blades out of the water for maintenance. c.2) Flight scraper or chain type ‫( زداﻳﻨﺪه ﺗﻴﻐﻪ اي ﻳﺎ ﻧﻮع زﻧﺠﻴﺮي‬2-‫ج‬ c.2) Flight scraper or chain type The flight scraper type of oil and sludge moving device consists of two parallel endless chains, one at each side of the channel, with flights connected to the chains across the channel width.

Sedimentation may be used for grit removal, particulate-matter removal in the primary settling basin, biological-floc removal in the activated-sludge settling basin, and chemical-floc removal when the chemical coagulation process is used. It is also used for solids concentration in sludge thickeners. However, in most cases, the primary purpose is to produce a clarified effluent. In designing sedimentation basins, consideration must be given to production of both a clarified effluent and a concentrated sludge. On the basis of the concentration and the tendency of particles to interact, four types of settling can occur:discrete particle, flocculent, hindered (also called zone), and compression (see Appendix H for description of these settling phenomena). ‫ ﻣﻼﺣﻈﺎت ﻣﺮﺑﻮط ﺑﻪ ﻃﺮاﺣﻲ‬2-8-7 7.8.2 Design considerations ‫اﻟﻒ( ﺣﻮﺿﭽﻪ ﻫﺎي ﭘﻴﺶ ﺗﻪ ﻧﺸﻴﻦ ﺳﺎزي ﻣﻤﻜﻦ اﺳﺖ در‬ a) Presedimentation basins may be constructed in excavated ground or out of steel or concrete.

In chemical applications, a chemical flocculent is often added to the waste water prior to granular-media filtration, to enhance oil removal. Additionally, 98 Feb 2010/ 1388 ‫ﺑﻬﻤﻦ‬ IPS-E-PR-730(1) granular-media filters can be designed and operated as simple coalescers, without chemicals, causing the small oil droplets to coalesce into larger ones as they pass through the filter bed. When filters are operated in this manner, the oil is subsequently removed from the water by gravity separation. This technique can be used on oil-field produced water, but should not be used for refinery or petrochemical plant waste water. Use of gravity filters due to high water demand and large bed areas should be avoided. ‫ ﺑﺪون‬،‫ﻫﺎي داﻧﻪ اي ﻣﻲ ﺗﻮاﻧﻨﺪ ﺑﺼﻮرت ﻣﻨﻌﻘﺪ ﻛﻨﻨﺪه ﺳﺎده‬ ‫ ﺑﺎ اﻳﺠﺎد ﻗﻄﺮات رﻳﺰ روﻏﻦ و ﺑﻪ ﻫﻢ‬، ‫اﺳﺘﻔﺎده از ﻣﻮاد ﺷﻴﻤﻴﺎﻳﻲ‬ ‫آﻣﻴﺨﺘﻦ آﻧﻬﺎ و اﻳﺠﺎد ذرات ﺑﺰرﮔﺘﺮدر ﻫﻨﮕﺎم ﻋﺒﻮر از ﺻﺎﻓﻲ‬ ‫ وﻗﺘﻲ ﺻﺎﻓﻲ ﻫﺎ ﺑﻪ اﻳﻦ روش‬.‫ﻃﺮاﺣﻲ و ﺑﻬﺮه ﺑﺮداري ﺷﻮﻧﺪ‬ ‫ روﻏﻦ ﻣﺘﻌﺎﻗﺒﺎ ﺑﻮﺳﻴﻠﻪ ﺟﺪاﺳﺎزي ﺛﻘﻠﻲ‬،‫ﺑﻬﺮه ﺑﺮداري ﻣﻲ ﮔﺮدﻧﺪ‬ ‫ اﻳﻦ ﺗﻜﻨﻴﻚ در آﺑﻬﺎي ﺗﻮﻟﻴﺪ ﺷﺪه در‬.‫از آب ﺟﺪا ﻣﻲ ﮔﺮدد‬ ‫ﻣﻨﺎﻃﻖ ﻧﻔﺘﻲ ﻗﺎﺑﻞ اﺳﺘﻔﺎده ﻣﻲ ﺑﺎﺷﺪ وﻟﻲ ﺑﺮاي ﭘﺴﺎب‬ ‫ اﺳﺘﻔﺎده از‬.‫واﺣﺪﻫﺎي ﭘﺎﻻﻳﺸﮕﺎﻫﻲ و ﭘﺘﺮوﺷﻴﻤﻲ ﻣﻨﺎﺳﺐ ﻧﻴﺴﺖ‬ ‫ﺻﺎﻓﻲ ﻫﺎي ﺛﻘﻠﻲ در ﻣﻮارد زﻳﺎد ﺑﻮدن آب ﻣﻮرد ﻧﻴﺎز و‬ .‫ﻫﻤﭽﻨﻴﻦ ﺑﺰرگ ﺑﻮدن ﺳﻄﺢ ﺑﺴﺘﺮﻫﺎ ﺑﺎﻳﺴﺘﻲ اﺟﺘﻨﺎب ﻧﻤﻮد‬ When possible, the design basis contaminant removal efficiency for granular media filters should be determined by tests using the particular waste stream of interest.

For grassroots and/or other installations where tests cannot be conducted, the following typical contaminant removal efficiencies can be used for granular media filters: ‫در ﻣﻮاﻗﻊ ﻣﻤﻜﻦ ﻣﺒﺎﻧﻲ ﻃﺮاﺣﻲ ﺑﺮاي ﻣﻘﺪار ﺑﺎزدﻫﻲ ﺣﺬف‬ ‫آﻻﻳﻨﺪه ﻫﺎ ﺑﺮاي ﺻﺎﻓﻲ ﻫﺎي ﺑﺎ ﺑﺴﺘﺮ داﻧﻪ اي ﺑﺎﻳﺴﺘﻲ ﺗﻮﺳﻂ‬ ‫ ﺑﺎ‬.‫آزﻣﺎﻳﺶ ﻫﺎﻳﻲ ﺑﺎ اﺳﺘﻔﺎده از ﭘﺴﺎب ﻫﺎي ﺧﺎص ﺗﻌﻴﻴﻦ ﮔﺮدد‬ ‫ ﻛﺎرﻫﺎي آزﻣﺎﻳﺸﮕﺎﻫﻲ ﺑﺮاي‬،‫اﺳﺘﻔﺎده از ﻳﻚ ﭘﺴﺎب ﻣﻮﺟﻮد‬ ‫ ﺗﺠﻤﻊ اﻓﺖ‬،‫ دوره ﺑﺮﮔﺸﺖ‬،‫ﺑﺮرﺳﻲ ﺧﻠﻮص ﻓﺎﺿﻼب ﺧﺮوﺟﻲ‬ ‫ ﻣﻮاد ﺷﻴﻤﻴﺎﻳﻲ و ﻣﻘﺪار ﺗﺰرﻳﻖ آﻧﻬﺎ ﺑﺎﻳﺴﺘﻲ‬، ‫ اﻓﺖ ﻓﺸﺎر‬، ‫ﻓﺸﺎر‬ ‫ ﺑﺮاي ﻧﺼﺐ از ﭘﺎﻳﻪ و ﻳﺎ ﺳﺎﻳﺮ روش‬.‫ﻗﺒﻞ از ﻃﺮاﺣﻲ اﻧﺠﺎم ﺷﻮﻧﺪ‬ ‫ ﺑﺎزدﻫﻲ ﻫﺎي‬،‫ﻫﺎي ﻧﺼﺐ ﻛﻪ اﻣﻜﺎن اﺟﺮاي آزﻣﺎﻳﺸﻲ ﻧﻤﻲ ﺑﺎﺷﺪ‬ ‫آﻻﻳﻨﺪه ﻫﺎي ﻧﻤﻮﻧﻪ زﻳﺮ ﺑﺮاي ﺻﺎﻓﻲ ﻫﺎي ﺑﺎ ﺑﺴﺘﺮ داﻧﻪ اي ﻗﺎﺑﻞ‬ : ‫اﺳﺘﻔﺎده ﻣﻲ ﺑﺎﺷﺪ‬ FILTER LOCATION API SEPARATOR EFF. ‫ﻣﺤﻞ ﺻﺎف‬ API ‫ﺑﺎزدﻫﻲ ﺟﺪاﻛﻨﻨﺪه‬ Residual oil level: : ‫ﺳﻄﺢ روﻏﻦ ﺗﻪ ﻣﺎﻧﺪ‬ less than 20 mg/L ‫ ﻣﻴﻠﻲ ﮔﺮم ﺑﺮ ﻟﻴﺘﺮ ﺗﻪ ﻣﺎﻧﺪ‬20 ‫ﻛﻤﺘﺮ از‬ Susp. sol. removal: : ‫ﺟﺪاﺳﺎزي ﺟﺎﻣﺪات ﻣﻌﻠﻖ‬ 5-day BOD removal5-day BOD removal: ‫ﺟﺪاﺳﺎزي‬BOD5: (*) : 80% to 90% ‫ درﺻﺪ‬90 ‫ ﺗﺎ‬80 BIOLOGICAL EFF. ‫ﺑﺎزدﻫﻲ ﺑﻴﻮﻟﻮژﻳﻜﻲ‬ 80 to 90% free ‫ درﺻﺪ ﺟﺪاﺳﺎزي روﻏﻦ آزاد‬90 ‫ ﺗﺎ‬80 80% to 90% ‫ درﺻﺪ‬90 ‫ ﺗﺎ‬80 30% (*) ‫ درﺻﺪ‬30 (*) ----- ‫ ﻧﺎﻣﺤﻠﻮل وﻗﺘﻲ ﻛﻪ ﺻﺎﻓﻲ‬BOD ‫ ﺑﺮ ﻣﺒﻨﺎي ﺟﺪاﺳﺎزي‬:(*) Based on the removal of insoluble BOD when the filter is used as a pretreatment process; this BOD reduction should not be expected when the filter is used for polishing.

In the field of waste water treatment, chemical Unit processes are usually used in conjunction with the physical Unit operations and the biological Unit processes, to meet treatment objectives. ‫ ﻛﻪ‬، ‫آن دﺳﺘﻪ از ﻓﺮآﻳﻨﺪﻫﺎي اﺳﺘﻔﺎده ﺷﺪه در ﺗﺼﻔﻴﻪ ي ﭘﺴﺎب‬ ‫در آن ﺗﻐﻴﻴﺮ ﺑﻪ وﺳﻴﻠﻪ ﻳﺎ از ﻃﺮﻳﻖ واﻛﻨﺶ ﺷﻴﻤﻴﺎﻳﻲ ﺻﻮرت‬ ‫ در‬.‫ ﻓﺮآﻳﻨﺪﻫﺎي واﺣﺪ ﺷﻴﻤﻴﺎﻳﻲ ﻧﺎﻣﻴﺪه ﻣﻲ ﺷﻮﻧﺪ‬،‫ﻣﻲ ﮔﻴﺮد‬ ،‫ ﺑﺮاي دﺳﺘﻴﺎﺑﻲ ﺑﻪ اﻫﺪاف ﺗﺼﻔﻴﻪ‬،‫زﻣﻴﻨﻪ ﺗﺼﻔﻴﻪي ﭘﺴﺎب‬ ‫ﻓﺮآﻳﻨﺪﻫﺎي واﺣﺪ ﺷﻴﻤﻴﺎﻳﻲ ﻣﻌﻤﻮﻻ ﺑﻪ ﻫﻤﺮاه ﻋﻤﻠﻴﺎت واﺣﺪ‬ .‫ﻓﻴﺰﻳﻜﻲ و ﻓﺮاﻳﻨﺪﻫﺎي واﺣﺪ ﺑﻴﻮﻟﻮژﻳﻜﻲ اﺳﺘﻔﺎده ﻣﻲ ﺷﻮﻧﺪ‬ Applications of chemical Unit processes in waste water treatment are presented in Table-12 below. In considering the application of the following chemical Unit processes, the inherent disadvantages associated with most chemical processes (activated carbon adsorption is an exception), as compared with the physical Unit operations, is that they are additive processes and cause an increase in the total dissolved-solids concentration of the waste water. If the treated waste water is to be reused, this can be a significant factor. Another disadvantage of chemical Unit processes is that they are all intensive in operating costs. ‫ﻛﺎرﺑﺮدﻫﺎي ﻓﺮآﻳﻨﺪﻫﺎي واﺣﺪ ﺷﻴﻤﻴﺎﻳﻲ در ﺗﺼﻔﻴﻪ ﭘﺴﺎب در‬ ‫در ﺑﺮرﺳﻲ ﻛﺎرﺑﺮد ﻓﺮآﻳﻨﺪﻫﺎي‬.‫ ﻧﺸﺎن داده ﺷﺪه اﺳﺖ‬12 ‫ﺟﺪول‬ ‫واﺣﺪ ﺷﻴﻤﻴﺎﻳﻲ زﻳﺮ ﻣﺘﻮﺟﻪ ﻣﻲ ﮔﺮدد ﻛﻪ ﻣﻀﺮات ذاﺗﻲ ﻣﺮﺑﻮط‬ ‫در‬،( ‫ﺑﻪ اﻛﺜﺮ ﻓﺮآﻳﻨﺪﻫﺎي ﺷﻴﻤﻴﺎﻳﻲ )ﺑﻪ اﺳﺘﺜﻨﺎي ﺟﺬب ﻛﺮﺑﻦ‬ ،‫ﻣﻘﺎﻳﺴﻪ ﺑﺎ ﻋﻤﻠﻴﺎت واﺣﺪ ﻓﻴﺰﻳﻜﻲ اﻳﻦ اﺳﺖ ﻛﻪ آﻧﻬﺎ‬ ‫ﻓﺮآﻳﻨﺪﻫﺎﻳﻲ اﻓﺰودﻧﻲ ﻫﺴﺘﻨﺪ و ﺑﺎﻋﺚ اﻓﺰاﻳﺶ ﻏﻠﻈﺖ ﻛﻞ‬ ‫ ﭘﺴﺎب‬،‫ اﮔﺮ ﻗﺮار ﺑﺎﺷﺪ‬.‫ﺟﺎﻣﺪات ﺣﻞ ﺷﺪه در ﭘﺴﺎب ﻣﻲ ﺷﻮﻧﺪ‬ ‫ ﻣﻮرد ذﻛﺮ ﺷﺪه ﻣﻲ ﺗﻮاﻧﺪ‬،‫ﻣﻮرد اﺳﺘﻔﺎده ي دوﺑﺎره ﻗﺮار ﮔﻴﺮد‬ ‫ ﻣﻀﺮت دﻳﮕﺮ ﻓﺮآﻳﻨﺪﻫﺎي واﺣﺪ‬.‫ﻋﺎﻣﻠﻲ ﻣﻬﻢ ﺗﻠﻘﻲ ﺷﻮد‬ .‫ﺷﻴﻤﻴﺎﻳﻲ ﺑﺎﻻ ﺑﻮدن ﻫﺰﻳﻨﻪ ﻫﺎي ﻋﻤﻠﻴﺎﺗﻲ آن ﻫﺎﺳﺖ‬ 109 Feb 2010/ 1388 ‫ﺑﻬﻤﻦ‬ IPS-E-PR-730(1) TABLE 12 - APPLICATIONS OF CHEMICAL UNIT PROCESSES IN WASTE WATER TREATMENT ‫ ﻛﺎرﺑﺮدﻫﺎي ﻓﺮآﻳﻨﺪﻫﺎي واﺣﺪ ﺷﻴﻤﻴﺎﻳﻲ در ﺗﺼﻔﻴﻪ ﭘﺴﺎب‬-12 ‫ﺟﺪول ﺷﻤﺎره‬ PROCESS APPLICATION ‫ﻓﺮآﻳﻨﺪ‬ ‫ﻛﺎرﺑﺮد‬ Advanced oxidation processes Removal of refractory organic compounds ‫ﻓﺮآﻳﻨﺪﻫﺎي اﻛﺴﻴﺪاﺳﻴﻮن ﭘﻴﺸﺮﻓﺘﻪ‬ ‫ﺣﺬف ﺗﺮﻛﻴﺒﺎت آﻟﻲ ﻻﻳﻪ ﻧﺴﻮز‬ ‫اﻧﻌﻘﺎد ﺷﻴﻤﻴﺎﻳﻲ‬ The chemical destabilization of particles in wastewater to bring about their aggregation during perikinetic and orthokinetic flocculation Chemical coagulation ‫ﺗﻀﻌﻴﻒ ﺷﻴﻤﻴﺎﻳﻲ ذرات ﻣﻮﺟﻮد در ﭘﺴﺎب ﺑﺮاي ﻣﺨﻠﻮط ﻛﺮدن آن ﻫﺎ در‬ ‫ﻃﻮل ﻟﺨﺘﻪ ﺳﺎزي ﭘﻴﺮاﺟﻨﺒﺸﻲ و ارﺗﻮ ﺟﻨﺒﺸﻲ‬ Chemical disinfection ‫ﮔﻨﺪزداﻳﻲ ﺷﻴﻤﻴﺎﻳﻲ‬ Disinfection with chlorine, chlorine compounds, bromine, and ozone ‫ ﺑﺮوم و ازن‬،‫ﺗﺮﻛﻴﺒﺎت ﻛﻠﺮ‬،‫ﮔﻨﺪزداﻳﻲ ﺑﺎﻛﻠﺮ‬ Control of slime growths in sewers ‫ﻛﻨﺘﺮل رﺷﺪ ﻟﺠﻦ در ﻣﺠﺮاﻫﺎي ﻓﺎﺿﻼب‬ Control of odors ‫ﻛﻨﺘﺮل ﻣﻮاد ﺑﻮدار‬ Chemical neutralization Control of PH ‫ﺧﻨﺜﻲ ﺳﺎزي ﺷﻴﻤﻴﺎﻳﻲ‬ Chemical oxidation ‫اﻛﺴﻴﺪاﺳﻴﻮن ﺷﻴﻤﻴﺎﻳﻲ‬ pH ‫ﻛﻨﺘﺮل‬ Removal of BOD, grease, etc, ‫ ﻏﻴﺮه‬،‫ روﻏﻦ‬،BOD ‫ﺣﺬف‬ Removal of ammonia (NH4+) (NH4+) ‫ﺣﺬف آﻣﻮﻧﻴﺎك‬ Destruction of microorganisms ‫ﻧﺎﺑﻮدي رﻳﺰ ﺟﺎﻧﺪارﻫﺎ‬ Control of odors in sewers, pump stations, and treatment plants ‫ و واﺣﺪﻫﺎي ﺗﺼﻔﻴﻪ‬،‫ﺟﺎﻳﮕﺎه ﻫﺎي ﺗﻠﻤﺒﻪ‬،‫ﻛﻨﺘﺮل ﺑﻮي ﻣﺠﺮاﻫﺎي ﻓﺎﺿﻼب‬ Removal of resistant organic compounds ‫ﺣﺪف ﺗﺮﻛﻴﺒﺎت آﻟﻲ ﻣﻘﺎوم‬ (to be continued) (‫)اداﻣﻪ دارد‬ 110 Feb 2010/ 1388 ‫ﺑﻬﻤﻦ‬ IPS-E-PR-730(1) TABLE 12(continued) (‫ )اداﻣﻪ‬-12 ‫ﺟﺪول‬ PROCESS APPLICATION ‫ﻓﺮآﻳﻨﺪ‬ ‫ﻛﺎرﺑﺮد‬ Chemical precipitation ‫رﺳﻮب دادن ﺷﻴﻤﻴﺎﻳﻲ‬ Enhancement removal of total suspended solids and BOD in primary sedimentation facilities ‫ در‬BOD ‫اﺻﻼح اﻓﺰاﻳﺶ ازﺑﻴﻦ ﺑﺮدن ﻛﻞ ﺟﺎﻣﺪات ﻣﻌﻠﻖ و‬ ‫اﻣﻜﺎﻧﺎت رﺳﻮب ﮔﺬاري اوﻟﻴﻪ‬ ‫ﺣﺬف ﻓﺴﻔﺮ‬ Removal of phosphorus ‫ﺣﺬف ﻓﻠﺰات ﺳﻨﮕﻴﻦ‬ Removal of heavy metals Physical-chemical treatment ‫ﺷﻴﻤﻴﺎﻳﻲ‬-‫ﺗﺼﻔﻴﻪ ﻓﻴﺰﻳﻜﻲ‬ Corrosion control in sewers due to H2S H2S ‫ﻛﻨﺘﺮل ﺧﻮردﮔﻲ در ﻣﺠﺮاﻫﺎي ﻓﺎﺿﻼب ﺑﻪ دﻟﻴﻞ وﺟﻮد‬ Chemical scale control ‫ﻛﻨﺘﺮل رﺳﻮب ﺷﻴﻤﻴﺎﻳﻲ‬ Control of scaling due to calcium carbonate and related compounds ‫ﻛﻨﺘﺮل ﺗﻪ ﻧﺸﺴﺖ ﺑﻪ دﻟﻴﻞ وﺟﻮد ﻛﺮﺑﻨﺎت ﻛﻠﺴﻴﻢ وﺗﺮﻛﻴﺒﺎت‬ ‫ﻣﺮﺑﻮط‬ Chemical stabilization Stabilization of treated effluents ‫ﺗﺜﺒﻴﺖ ﺷﻴﻤﻴﺎﻳﻲ‬ Ion exchange ‫ﺗﺒﺎدل ﻳﻮن‬ ‫ﺗﺜﺒﻴﺖ ﻓﺎﺿﻼﺑﻬﺎي ﺧﺮوﺟﻲ ﺗﺼﻔﻴﻪ ﺷﺪه‬ Removal of ammonia (NH4+), heavy metals, total dissolved solids ‫ﻛﻞ ﺟﺎﻣﺪات ﺣﻞ ﺷﺪه‬،‫ﻓﻠﺰات ﺳﻨﮕﻴﻦ‬،(NH4+)‫دﻓﻊآﻣﻮﻧﻴﺎك‬ Removal of organic compounds ‫دﻓﻊ ﺗﺮﻛﻴﺒﺎت آﻟﻲ‬ ، ‫ ﺟﻤﻊ آوري‬،‫ﺑﺮاي ﻣﺸﺎﻫﺪه ﻛﺎرﺑﺮدﻫﺎي ﺷﻴﻤﻴﺎﻳﻲ دﻳﮕﺮ‬ ‫ ﻣﻲ ﺗﻮان ﺑﻪ ﭘﻴﻮﺳﺖ ﻣﺸﺨﺼﺎت اﻳﻦ‬،‫ و دﻓﻊ ﭘﺴﺎب‬،‫ﺗﺼﻔﻴﻪ‬ .‫اﺳﺘﺎﻧﺪارد ﻣﺮاﺟﻌﻪ ﻛﺮد‬ For additional chemical applications in waste water collection, treatment, and disposal, reference can be made to Appendix J of this Standard Specification. ‫ رﺳﻮب دادن ﺷﻴﻤﻴﺎﻳﻲ‬2-8 8.2 Chemical Precipitation ‫رﺳﻮب دادن ﺷﻴﻤﻴﺎﻳﻲ در ﺗﺼﻔﻴﻪ ﭘﺴﺎب ﺷﺎﻣﻞ اﻓﺰودن ﻣﻮاد‬ ‫ﺷﻴﻤﻴﺎﻳﻲ ﺑﺮاي ﺗﻐﻴﻴﺮ وﺿﻌﻴﺖ ﻓﻴﺰﻳﻜﻲ ﺟﺎﻣﺪات ﺣﻞ ﺷﺪه‬ . ‫وﻣﻌﻠﻖ و ﺗﺴﻬﻴﻞ دﻓﻊ آن ﻫﺎ ﺑﻪ وﺳﻴﻠﻪ رﺳﻮب ﮔﺬاري اﺳﺖ‬ ‫ﻓﺮآﻳﻨﺪ ﻫﺎي ﺷﻴﻤﻴﺎﻳﻲ ﻣﻲ ﺗﻮاﻧﺪ ﺑﻪ ﻫﻤﺮاه ﻋﻤﻠﻴﺎت ﻣﺘﻌﺪد‬ ‫ در ﺗﺼﻔﻴﻪ ﺛﺎﻧﻮﻳﻪ ﭘﺴﺎب ﺗﺼﻔﻴﻪ ﻧﺸﺪه از ﺟﻤﻠﻪ در‬،‫ﻓﻴﺰﻳﻜﻲ‬ ‫ ﻣﻌﻤﻮل ﺗﺮﻳﻦ‬.‫ﺣﺬف ﻧﻴﺘﺮوﮋن ﻳﺎ ﻓﺴﻔﺮ ﻳﺎ ﻫﺮدو اﺳﺘﻔﺎده ﮔﺮدد‬ ‫ در ﺟﺪول‬، ‫ﻣﻮاد ﺷﻴﻤﻴﺎﻳﻲ اﺳﺘﻔﺎده ﺷﺪه در ﺗﺼﻔﻴﻪ ﭘﺴﺎب‬ ‫ درﺟﻪ ﺗﺼﻔﻴﻪ ﺑﺪﺳﺖ آﻣﺪه‬. ‫ ﻧﺸﺎن داده ﺷﺪه اﺳﺖ‬13 ‫ﺷﻤﺎره‬ Chemical precipitation in waste water treatment involves the addition of chemicals to alter the physical state of dissolved and suspended solids and to facilitate their removal by sedimentation.

Toxicants either kill microorganisms or inhibit their growth. The effect depends on concentration, contact time, and the environment (e.g., pH). A number of toxic materials are potentially present in refinery and petrochemical plant waste waters, including zinc, chromium, copper, cyanide, sulfide, biocides, furfural, and certain other organic compounds. In addition, highly alkaline or acid discharges may be toxic. Besides being toxic, sulfides preferentially consume oxygen and can create an anaerobic environment. Table 19 gives guidance on the limiting concentrations for certain materials. Heavy metals, in general, inhibit the activated sludge process. Dissolved heavy metal ions (cadmium, cobalt, copper, dichromate, ferric iron, lead, manganese, nickel, silver, vanadium, and zinc), above certain concentrations, impede biological metabolism. The effect of any particular concentration of these depends on the environment; therefore, it is not possible to give exact concentration limits for most of these heavy metals. Microorganisms can tolerate only 1 mg/L or less of some heavy metals (cadmium, copper, silver), but other metal ions (ferric iron, manganese, nickel, vanadium) have been successfully handled at 10 mg/L with little or no loss in efficiency. .‫ﻓﻌﺎل آﺳﻴﺐ ﺟﺪي زده و ﺑﺎزدﻫﻲ آن را ﻛﺎﻫﺶ دﻫﺪ‬ ‫ﻣﺴﻤﻮم ﻛﻨﻨﺪه ﻫﺎ ﻳﺎ ﻣﻮﺟﺐ ﻣﺮگ رﻳﺰ ﺟﺎﻧﺪارﻫﺎ ﻣﻲ ﺷﻮﻧﺪ‬ ،‫ اﻳﻦ ﺗﺎﺛﻴﺮ ﺗﺎﺑﻌﻲ از ﻏﻠﻈﺖ‬.‫و ﻳﺎ ﻣﺎﻧﻊ رﺷﺪ آﻧﻬﺎ ﻣﻲ ﮔﺮدﻧﺪ‬ ‫ ﺗﻌﺪادي از‬.‫ اﺳﺖ‬pH ‫زﻣﺎن ﺗﻤﺎس و ﺷﺮاﻳﻂ ﻣﺤﻴﻄﻲ ﻣﺎﻧﻨﺪ‬ ‫ﻣﻮاد ﺳﻤﻲ ﻛﻪ ﺑﺼﻮرت ﺑﺎﻟﻘﻮه در ﭘﺴﺎب واﺣﺪﻫﺎي‬ ،‫ ﻛﺮوم‬،‫ﭘﺘﺮوﺷﻴﻤﻲ و ﭘﺎﻻﻳﺸﮕﺎﻫﻲ وﺟﻮد دارﻧﺪ ﺷﺎﻣﻞ روي‬ ‫ ﻓﻮرﻓﻮرال و دﻳﮕﺮ‬،‫ ﺑﺎﻳﻮﺳﺎﻳﺪ‬،‫ ﺳﻮﻟﻔﻴﺪ‬،‫ ﺳﻴﺎﻧﻴﺪ‬،‫ﻣﺲ‬ ‫ ﺑﻌﻼوه ﻣﻮاد ﺗﺨﻠﻴﻪ ﺷﺪه ﺧﻴﻠﻲ‬.‫ﺗﺮﻛﻴﺒﺎت آﻟﻲ ﻣﻲﺑﺎﺷﻨﺪ‬ ‫ ﺳﻮﻟﻔﻴﺪﻫﺎ‬.‫ﻗﻠﻴﺎﺋﻲ ﻳﺎ ﺧﻴﻠﻲ اﺳﻴﺪي ﻣﻲ ﺗﻮاﻧﺪ ﺳﻤﻲ ﺑﺎﺷﻨﺪ‬ ‫ ﻣﺼﺮف ﻛﻨﻨﺪه ﺗﺮﺟﻴﺤﻲ اﻛﺴﻴﮋن‬،‫در ﻛﻨﺎر ﺳﻤﻲ ﺑﻮدن‬ .‫ﻫﺴﺘﻨﺪ و ﻣﻲ ﺗﻮاﻧﻨﺪ ﻳﻚ ﻣﺤﻴﻂ ﺑﻲ ﻫﻮازي اﻳﺠﺎد ﻛﻨﻨﺪ‬ ‫درﺑﺎره ﻣﺤﺪودﻳﺖ ﻏﻠﻈﺖ ﺑﺮﺧﻲ از ﻣﻮاد ﻣﻴﺘﻮان ﺑﻪ ﺟﺪول‬ ‫ ﻓﻠﺰات ﺳﻨﮕﻴﻦ ﺑﻄﻮر ﻛﻠﻲ ﻣﺎﻧﻊ اﻧﺠﺎم‬.‫ ﻣﺮاﺟﻌﻪ ﻧﻤﻮد‬19 ‫ ﻳﻮن ﻫﺎي ﻓﻠﺰات ﺳﻨﮕﻴﻦ‬.‫ﻓﺮاﻳﻨﺪ ﻟﺠﻦ ﻓﻌﺎل ﻣﻲ ﺷﻮﻧﺪ‬ ،‫ ﺳﺮب‬،‫ آﻫﻦ‬،‫ دي ﻛﺮوﻣﺎت‬،‫ ﻣﺲ‬،‫ ﻛﺒﺎﻟﺖ‬،‫ﻣﺤﻠﻮل )ﻛﺎدﻣﻴﻮم‬ ‫ واﻧﺎدﻳﻮم و روي( در ﻣﻘﺎدﻳﺮ ﺑﻴﺶ از‬،‫ ﻧﻘﺮه‬،‫ ﻧﻴﻜﻞ‬،‫ﻣﻨﮕﻨﺰ‬ ‫ ﺗﺎﺛﻴﺮ‬.‫ﺣﺪ ﻣﺠﺎز ﻣﺎﻧﻊ ﺳﻮﺧﺖ و ﺳﺎز ﺑﻴﻮﻟﻮژﻳﻜﻲ ﻣﻲ ﺷﻮﻧﺪ‬ ‫ﻫﺮ ﻏﻠﻈﺘﻲ از اﻳﻦ ﻣﻮاد ﺑﻪ ﻣﺤﻴﻂ ﺑﺴﺘﮕﻲ دارد ﺑﻨﺎﺑﺮاﻳﻦ‬ ‫ﺗﻌﻴﻴﻦ ﻣﻘﺪار ﻏﻠﻈﺖ دﻗﻴﻖ ﺑﺮاي ﺑﻴﺸﺘﺮ اﻳﻦ ﻓﻠﺰات ﺳﻨﮕﻴﻦ‬ ‫ رﻳﺰ ﺟﺎﻧﺪارﻫﺎ در ﺑﺮاﺑﺮ ﺑﻌﻀﻲ ﻓﻠﺰات‬.‫اﻣﻜﺎن ﭘﺬﻳﺮ ﻧﻴﺴﺖ‬ ‫ ﻣﻴﻠﻲ‬1 ‫ ﻧﻘﺮه( ﻣﻲ ﺗﻮاﻧﻨﺪ ﻓﻘﻂ ﺗﺎ‬،‫ ﻣﺲ‬،‫ﺳﻨﮕﻴﻦ )ﻛﺎدﻣﻴﻮم‬ ‫ اﻣﺎ دﻳﮕﺮ ﻳﻮن ﻫﺎي ﻓﻠﺰي‬،‫ﮔﺮم در ﻟﻴﺘﺮ ﺗﺤﻤﻞ داﺷﺘﻪ ﺑﺎﺷﻨﺪ‬ ‫ ﻣﻴﻠﻲ‬10 ‫ واﻧﺎدﻳﻮم( را ﺑﺎ ﻣﻮﻓﻘﻴﺖ ﺗﺎ‬،‫ ﻧﻴﻜﻞ‬،‫ ﻣﻨﮕﻨﺰ‬،‫)آﻫﻦ‬ .‫ﮔﺮم ﺑﺮ ﻟﻴﺘﺮ ﺑﺪون ﻛﺎﻫﺶ در ﺑﺎزدﻫﻲ ﻣﻲ ﭘﺬﻳﺮﻧﺪ‬ Organic compounds which are toxic to the microorganisms will inhibit their utilization of other materials.
