Background
 General Manager of Graton Community Services District
Sanitation & Parks
 President: International Wastewater Solutions
Corporation
 Inventor of US patent No. 7,658,851 AN APPARATUS
AND METHOD FOR GROWING BACTERIA”, for use in
wastewater treatment, biological pest management,
bioremediation of soil and wastes.
 Inventor of US patent No. 8114659 “A DEVICE AND
METHOD FOR THE CATALYTIC TREATMENT OF A
MEDIA”.
Upgrading Graton: From
Secondary Treatment to Title 22
and a Nursery
 Graton is receiving $6 million Dollars in Funding from the
State Water Resources Control Board.
 Construction of a Tertiary Wastewater Treatment facility.


SAF pond algae removalFuzzy Filter CoGEN Pasteurization. Title 22.
Composting
 Existing Treatment process a series of facultative oxidation
ponds, recirculation, denitrification.

Amonox process with White Knight, IOS-500 bacteria, and
recirculation of nitrite with influent ammonia to yield N2 gas.
 Storage Pond Algae & cyanobacteria Control with AquaMarine Shadow, a food grade colorant.
Upgrade at Graton: From
Secondary treatment ponds to the
nursery
 Suspended Air Floatation (SAF) floats and removes the
oxidation pond algae and bacteria as a 5% sludge.
 The SAF underflow is then depth filtered with a Tertiary
“Fuzzy Filter” to remove algae and bacteria to meet Title
22 Tertiary requirements followed by pasteurization.
 SAF solids are dewatered in bins and composted to make
40 CFR-503 Class A superior grade bio-solids.
 Biosolids are used in our nursery to grow specimen trees.
 Trees, and sedges will be sold to cities for urban plantings
and storm water control.
From the oil fields to the
wastewater stream
 Introduction to the White Knight TM” microbial
inoculator generator and “IOS-500 TM”
Microbial inoculum.
 How it works with crude oil. 430,000 ppm in 45
days.
 How it works with FOG. Enzymes break down
fats and consume carbon.
 Benefits Low cost, down stream activity.

How the FOG control system
works
• “White Knight™” is a patented technology designed to
continuously inoculate treatment vessels with large
numbers of very powerful non-pathogenic cultures of IOS500 bacteria and generate enzymes.
• Airlift mixing recirculation and fine bubble aeration
principles bring these bacteria into contact with fixed film
substrate and the suspended organic compounds like FOG
in a treatment vessel.
• These pure cultures of bacteria grow at logarithmic rates
as they voraciously digest most of the fats, oils grease and
organic pollutants that are found in wastewater.

Growing Bacteria
Economically
 FOG control is accomplished by continuously growing and
applying overwhelming numbers of the right type of
bacteria economically using:
 The White Knight TM with IOS-500 TM microbes.
 Bacteria are encouraged to Buildup in a grease trap, lift
station wet well, or “Nursery Tank” under aeration.
 Because of their rapid growth rates, Bacterial Farming
techniques are more economical than purchasing large
quantities of freeze dried cultures, or enzymes.
