ERI contains a blend of ferrous sulfate or ferrous chloride with micronutrients, vitamins, minerals, trace elements, & small amounts of catalytic cofactors.
These ingredients work together as catalytic cofactors to increase the rate of enzymatic reactions within a system.
Using ERI reduces the pounds of iron needed to successfully treat a line by 60%-80%. This reduces the cost to the client while providing:
•Sulfide and organic odors removal,
•Grease reduction, and
More information about how cities and industries are using ERI is available in our case studies.
The iron salts in ERI have two functions; first, they binds water phase sulfides, removing the most noticeable source of odor and corrosion, and, second, they are a trace element used by a system’s bacteria in their metabolism. Iron salts have been used for years to control odors and corrosion in collection and conveyance lines by removing dissolved sulfides.
•Reduce vapor phase hydrogen sulfide levels to 5 PPM,
•Lower water phase sulfides to .5 mg/L,
•Control grease, and
•Remove organic odors.
Catalytic cofactors are the link between bacterial enzymes and organic substrates, and they are needed to break down organic material. If these cofactors or co-enzymes are absent or not readily available, the enzymatic reactions will not happen. When the proper type and quantity of cofactors are present, millions of enzymatic reactions can occur each second. ERI speed up the rate of reaction by ensuring that a system contains these necessary components.
The ingredients of ERI are present in safe amounts and these components are used in everyday metabolic reactions by humans and animals.
The combination of the two products contained in ERI allow the iron salts to scavenge hydrogen sulfide, while the catalytic cofactors reduce the long-chain volatile fatty acids to shorter chain acids, reducing grease and removing organic odors such as methyl mercaptans and dimethyl disulfides. Grease destroyed by this process does not reagglomerate.
The catalytic cofactor base used in ERI, which is the same contained in our product Biocope, has been included in university-sponsored testing in which its ability to reduce sludge, control odors, and degrade volatile fatty acids has been demonstrated. Extensive field testing and controlled laboratory bench testing found that Biocope:
•Breaks down volatile fatty acids,
•Reduces sludge volume, and
•Decreases the rate of microbial corrosion of metal and concrete.
