BIOLOGICAL-ENZYMES
There are several types and configurations of sewage treatment plants. Some have three stages, some have more as they may utilize UV disinfection or chlorinate and de-chlorinate the outlet water. Using our biological-enzymes are able to work with any size or configuration of treatment plants and operate with any of the systems or tanks usually constructed in such plants. Compressed air aeration tanks, rotating arm aeration tanks (seen below) or any of the other designs will allow our biological enzymes to do their work most efficiently.
Our biological enzyme treatment does not require a degreasing stage for oil and fats or UV-Chlorination (shown below) for disinfection and pathogen control which lowers operational costs. These substrates are bacterial food consumed by our microbes and converted into proteins and amino acids.
Even in a simple two-stage treatment plant we can be compliant with EPA standards. For irrigation or water discharge into a lake, sea, river or pond, the simple two-stage treatment process described above with our biological enzymes are sufficient. Only if the effluent outlet water will be used as potable water, will additional stages be required.
EXAMPLE In this example, the wastewater treatment plant is processing 3.5 million gallons of raw sewage daily. The plant’s effluent discharge has nutrient levels of total phosphorus of 3.5 mg/L and dissolved nitrogen of 22 mg/L. Regulatory agencies require the total phosphorus levels to be less than 1.0 mg/L and dissolved nitrogen less than 9.0 mg/L. This plant has six stages of process:

PLANT DOSING
The plant will require 1,325 Kg of our biological enzymes per day initially for 15 days. Thereafter, dosing will drop to 26 Kg of our microbes per day during the warmer seasons. Daily dosing is accomplished through a peristaltic pump for consistency. NUTRIENT TREATMENT
Shortly after dosing the nutrients dropped 95% in the effluent discharge, to approximately 0.18 mg/L for total phosphorus and 1.1 mg/L for dissolved nitrogen. This treatment plant is now 83% lower that the required regulatory compliance nutrient levels. In addition, the plant odors have diminished significantly. FERTILIZER PRODUCTS
The active biosolids recovered can be sold as high-grade fertilizer and in this example the treatment plant will produce 8 tons of pathogen-free organic fertilizer daily. PATHOGENS
Our biological enzymes will decompose all inert organic matter and eliminate all pathogens rapidly, such as E-coli and Salmonella. The treatment plant is now compliant with EPA standards for pathogen control and no longer requires UV treatment. This will save on chemicals, operational and power costs. It is now practical to use both the treated water and the active biosolids in agricultural scenarios. The active biosolids are totally pathogen-free and can be classified as Class A EQ (Exceptional Quality). This standard is used to describe a biosolids product that not only meets, but exceeds, all Class A pathogen reduction metals and VAR requirements. |
