Abstract

Wastewater treatment plants for the removal of organic matter, suspended solids and other pollutants that Includes pre-treatment compartments Biofilm aeration and biofilm feed chamber thrive on structures that support biofilm that do not move and soak in The mixed liquid of the biofilm aeration chamber Underwater aeration combination Or surfaces, and a reduction in the size of the suspended solid particles occurs, thus causing the flow of Sufficient fluid within the biofilm aeration chamber, this combination of the flow of Sufficient flow and reduced size of suspended organic particles contribute to efficient digestion of the material. Organic matter and pollutants by biofilms that grow on structures supporting the immersed biofilm. In the aeration chamber for the biofilm This results in a more efficient digestion process. In addition, the treated effluent has a high dissolved oxygen content and low BOD and SS. Finishing machines and processes have the following advantages. Low MLSS concentration, shorter biofilm formation time. No system clogging, good response to immediate loads, effluent with high DO, uniform effluent quality, sludge removal, shortened wastewater treatment time, temperature insensitive process, easy treatment plant design. The treatment plant of this invention is small compared to the ordinary treatment plant, this invention can be a significant step in making drinking water, consuming all things. Absolutely during therapy low The invention provides a very cost-effective, permissible process - other purification methods and processes that do not affect the volume and BOD:
