CORROSION CONTROL
Prevention of Rust

On of the most damaging effects on equipment is rusting. Rust is an oxidation reaction. Moisture on metal is not a good thing when there are oxidizing agents around. Almost any cleaner used today is an oxidizer. Ammonia and bleach will oxidize metals, causing rusted equipment, thereby increasing operations costs over time.

Antioxidants reverse oxidation (that is what the “anti” means). Antioxidants are chelated minerals and vitamins. Cobra EM-1® is fermented with cane molasses. Cane molasses have roughly 40 different trace materials. The microbes in Cobra EM-1® will synthesize various bio-available vitamin compounds (including B complex and Vitamin A) and enzymes during the fermentation process. Therefore, Cobra EM-1® Waste Treatment is known to reverse putrefaction and oxidation through secreted by-products, namely, antioxidants. Antioxidants help with pH balance and are known for preventing and even reversing corrosion.


Prevention of Crowning

The pH balance also contributes to prevention of H2S combining with water vapour and forming H2SO4, the main cause of crowning in sewer lines. Thiobacillus bacteria are the same bacteria that are used in strip mining to produce the acid wash. These bacteria are found everywhere on earth, but they need a certain pH, water, and sulphur to form sulphuric acid. The wastewater vapours in sewer lines provide the perfect environment for sulphuric acid production.

The microbes in Cobra EM-1® not only release O2 during their respiration which raises the pH, they also ingest a tremendous amount of sulphur, therefore removing it from the waste stream.

Rising corrosive gases in lift stations can be dealt with through several types of applications and targeted activation with Cobra EM-1® waste treatment, thereby preventing corrosion from outset. With repeated applications of Cobra EM-1® waste treatment to lift-station’s pumps, housing, and concrete, corrosion and rusting can actually be reversed.

In wastewater, antioxidants have a scavenging effect in the treatment system, pulling compounds out of suspension by combining with salts, thus causing a crystallization formation into a benign salt. By preventing various salts and mineral formation build up, the pipes will be polished without the need for mechanical cleaning. This all equals saving the municipality and the taxpayers money.


FAT, OILS AND GREASE

Effective Micro-organisms Technology offers a unique approach to dealing with fats, oils and grease. Instead of emulsifying them, as enzyme products do, Cobra EM-1® will digest them, eliminating them from the system.

This is evidence by a reduction of BOD and COD, after application directly into grease traps, within the waste stream. Cobra EM-1® waste treatment lowers the cloud point of the FOGs within the trap, eliminating the formation of paraffin’s, thereby reducing gas pockets of H2S gas formed around putrefactive food particles.

Cobra EM-1® waste treatment improves efficiency of the treatment plant skimmer tanks to capture a greater amount of grease.

Biological polishing of the sewer pipes occurs as the Cobra EM-1® waste treatment is seeded throughout the collection system, thus reducing clogging and crowning from saponifiable or non-saponifiable grease.
