Project name:
Control of hazardous substances in the Baltic Sea Region;
COHIBA
Minutes of the training about
Control of hazardous substances in the Baltic Sea Region; COHIBA water and
sewage management
24.11.2011
Poznań, Poland
Participants: find participants list attached (30 participants in total)
Main goals of the training:
 present research of COHIBA project over 11 substances of specific concern to the
Baltic Sea through HELCOMs Baltic Sea Action Plan,
 provide information on the effects of water and wastewater management on the
status of surface waters in Poland,
 discuss new standards of technology and wastewater municipal and industrial,
 pay attention to legislative issues in Poland and the need to change the legal
provisions relating, e.g. survey methods or technologies of waste water treatment.
Target group:
 offices and staff representatives of the Regional Directorate of Environmental
Protection,
 experts in the field of wastewater treatment,
 private companies.
Discussion issues:

Opening
Dr Janina Fudała IETU Director opened the training and welcomed the guests. She
pointed to the need to implement similar meetings, which are an opportunity to
address the problem of water pollution in the Baltic Sea and to begin discussions on
ways to improve his condition. She asked prof. dr. hab. inż. Jana Suschka to
conduct the training and presented the goals of the training and the agenda.

Introduction. COHIBA Project: objectives and results (Dr Urszula Zielonka,
IETU)
Ms Urszula Zielonka introduced briefly the goals of project and all work packages.,
Presented the results and objectives of the COHIBA project.

Emissions of hazardous substances from municipal wastewater treatment
plants (Dr Urszula Zielonka, IETU)
Dr Urszula Zielonka gave an overview of WP3 results. She emphasize that the study
samples were collected following: effluent from MWWTPs and IWWTP, sewage
sludge, landfill leachate and storm water. Presented chemical analysis made in the
COHIBA project. She presented chemical results from researches of municupal waste
water treatment plants (effluents and sewage sludge). Next discussed about
dischareges of hazardous substances/ group substances to water in Poland.


Identification of emission sources and estimating the loads of substances
into the environment (dr Janusz Krupanek, IETU )
Mr Janusz Krupanek presented a diffuse source of test substances in the COHIBA
project. He stressed the problem of dioxin and HBCD emissions in Poland, whose
source is waste combustion. The next section discusses the occurrence of an impact
assessment via “POP Cycling” model which is carried out in the project.

Technologies and standards for municipal wastewater treatment (Prof. Zofia
Sadecka, University in Zielona Góra)
Ms. Sadecka gave a presentation about MWWTPs in Poland. She stressed in recent
years the amount of raw sewage in Poland is decreasing. Ms. Sadecka presented the
current legislation regarding the monitoring of water and pointed to the inadequate
provisions and proposed amendments to those records. Then presented methods for
municipal waste water treatment plants and eliminate ways of them some of the 11
substances studied in the project COHIBA. She stressed that the removal of many
substances is possible with proper planning of the purification process.

The role of waste management in relation to dangerous substances
(Krzysztof Tyrała, ROT Establishment)
Mr Tyrała was absent because of desease.

Progress in industrial waste water treatment technology
(Prof. Krzysztof Barbusiński, Silesian University of Technology )
Mr Krzysztof Barbusiński gave a presentation about the new technologies and
standards for industrial wastewater tratment plants. In the first part of his
presentation Mr Krzysztof Barbusiński pointed to the need to make technological and
economic analysis, which should precede the process of purification plants. First of
all need to determine exactly the and result: pretreatment waste water or fully
purified sewage. Presented the treatment plant scheme with innovative solutions
depending on kind of sewage. Among the advanced methods discussed method of
AOPs. Pointed to the good effects of this technology, mainly associated with dioxins
and pesticides removal. Unfortunately it is not yet widespread in Poland.

Summarising the training day and providing information about further
activities in the project (prof Jan Suschka, IETU)
Mr Jan Suchka summarised the training day. Ms Urszula Zielonka informed the
participants about the next activities in the project, giving an overview which
information materials and guidance documents will be produced and by when they
are available for a wider audience.
Then began a discussion of the meeting. Participants of the training speakers to ask
questions.
Summary of discussion:
- there is a significant problem with estimating the cost effectiveness for
municipal and industrial wastewater treatment plants. Each plant produces
wastewater must be considered individually.
- discuss the problem of onsite wastewater treatment systems in Poland.
Despite the legal regulations in Poland is much installed waste water
treatment plants. Problem may be small waste water treatements plants (< 2
000 PE) and individual waste water treatment plants on the vilages areas.

-
Discuss about new methods of treatment waste water AOPs and posibilities of
biodegradiation hazardous substances.
Main conclusions:

Poland needs a new wastewater treatment technology for elimination of hazardous
substances in particular for phenolic substances and chlorinated paraffins (SCCPs
and MCCPs),

requires better control of construction of onsite wastewater treatment systems.
Very important is control of these sunstances on the WWTPs, but in Poland needs
legal requirements,

should be to plan the sludge management.
