MicroChoice ® WWT

A concentrated, dry blend of stabilized bacterial spores and micronutrients formulated for use in food and municipal wastewater treatment.

Properly sized and managed wastewater treatment plants allow a food processing facility or municipality to discharge clean and environmentally responsible effluent. However, with the increasing demand placed on these facilities, effluent that is not properly treated makes its way into our rivers, streams, and lakes. In an effort to help these plants meet legal and environmental specifications, as well as for the protection of our waterways, we’ve worked with industry scientists to develop MicroChoice® WWT.

MicroChoice® WWT contains a unique blend of non-engineered cultures that rapidly digest organic wastes. These bacteria are supplied on a proprietary micronutrient carrier that provides accelerated germination, growth, and enzyme production to maximize the reduction of BOD, COD, suspended solids, ammonia, and odors. 

Our Total System Approach begins with the Wastewater Treatment Questionnaire. By reviewing the completed questionnaire, our technical staff will have a better understanding of the system to be treated and the problems occurring in the system. This information will be used to determine the appropriate application rate for the facility under investigation.

Our technical staff was asked to develop a treatment schedule to reduce the Biochemical Oxygen Demand (BOD) of the effluent from a food processing wastewater treatment plant. Utilizing the Total System Approachand information gained from the Wastewater Treatment Questionnaire, the decision was made to augment with a nutrient blend as well as the bacteria in MicroChoice® WWT. Adjustments were also made to the pH and dissolved oxygen levels in portions of the treatment system. As demonstrated above, this approach resulted in a very quick reduction in the BOD of the effluent.
