ENVIROGEN

Results of Independent Laboratory Tests.

BIODEGRADATION /AQUATIC SAFETY The COD is 3500 mg/L. The test method used was Hach's Reactor Digestion Method for Waste Water and Sea Water. The Hach Reactor Digestion Method is a semi-macro adaptation of the Standard Methods. (For comparison, organic acids, surfactants, and glycol ethers will typically have CODs between 1,000,000 - 2,000,000 mg/L. THE BOD IS 500 mg/L after 5 days and 600 mg/L at 10 days. The test method used was Part 507 Oxygen Demand (Biochemical) of the Standard Methods for Examination of Water and Wastewater, 1985, 16th Edition.

Food/Beverage Facilities and Waste Disposal Regulations

The standard for discharging waste into the sewage system is a pH level in the range of 5.5 to 9.5, depending upon the municipality. Each municipality has its own pH requirement standards. 

Before any acid waste can be released into the sewage system it must be neutralized to meet the local standards. If the waste has a pH of less than 5.5, caustics have to be added to bring the pH up to meet the disposal requirements. Conversely, if the pH is higher than 9.5 then an acid must be added to bring the pH down to acceptable levels. In dealing with the disposal of toxic waste, acid is not the major issue. BOD (Biological Oxygen Demand) is. A very low BOD level is good because it does not place such a high load on the sewage treatment.

Waste material contains several difference substances aside from the soil being cleaned - cleaners, acids, phosphates, silicates, solvents, butyl for example. All waste materials have their own pH and BOD levels that can further complicate the disposal procedure. Again, surcharges are levied for hard to dispose of waste. 


ENVIROGEN makes waste disposal easy.

ENVIROGEN makes it very easy to control the pH in waste materials. Compared to strong acids, a very small amount of caustic is required to bring ENVIROGEN up to regulation standards. For example, phosphoric and muriatic acids (muriatic is 32% hydrochloric acid and is the highest level of concentration available) are harder to neutralize than ENVIROGEN. This is because they are strong, corrosive acids and therefore need more caustics to neutralize. Of even greater concern is the danger of mixing acids with caustic because this can cause a violent reaction.
