 The treatment system BIONEST uses a biological process using a microbial culture, set on a medium non-biodegradable, with alternating purification processes aerobic and anaerobic. This technology is distinguished by its patented media that allows an effective adhesion of the bacterial population depolluante and provides greater surface active reactions nitrification / denitrification. The effluent at the reactor outlet biological technology BIONEST presents a much higher quality government standards, and in all seasons. HIGHLIGHTS Technology * Media with a very active and surface texture promoting rapid growth of microorganisms * Water resistant to shocks, changes in temperature and changes in charge of the tributary Environment * Media non-toxic and non-biodegradable * Reduction of more than 99% of faecal coliform * Removal of more than 98% of the BOD5 and more than 96% of MES Economy * Media synthetic among the least expensive per square meter on the market * Minimum Maintenance Cost * Cost of operation modest OBJECTIVES OF THE PROJECT / PHASES Since 1997, the objective of Bionest Technologies Inc. is to develop and market a system of quality higher than the conventional options for the treatment of sewage while economic and require little maintenance. Advised by experts at the University of Guelph in Ontario (site of Alfred), Bionest Technology inc. has developed its system under various conditions. The draft of a system adapted to a residence of four bedrooms was then subjected to the evaluation of the Committee on new technologies wastewater treatment. This committee is composed of the Ministry of Municipal Affairs, Sports and Recreation and the Ministry of Environment Quebec (MENV).  The last step is to obtain a certification by the Bureau de normalization du Quebec (BNQ) and the NSF. The conventional septic installation, which typically consists of a septic tank and a purifying element built with trenches filter or a bed absorption, is the most widely used for the in situ treatment of sewage effluent domestic Residents isolated. The major problem of the use of conventional septic system is the variability of the soil. In several regions, the soil does not have the characteristics appropriate to treat the effluent from a conventional septic tank or the soil or the surface of the ground can simply not a conventional septic installation. Finally, the new government standards require more efficient management of domestic sewage. The treatment system BIONEST is a biological process to set microbial culture alternating with aerobic and anaerobic environment. The primary treatment is done in the septic tank. The media BIONEST is placed in the second compartment of the pit, with a canning sludge and a primary. The advanced secondary treatment is carried out in a box identical to that of a septic tank, the reactor BIONEST. The media BIONEST is placed inside two compartments of the box. The first compartment is ventilated at all times by two broadcasters-thin bubbles that can initiate reactions nitrification. The oxidation of ammonia nitrate is completed in the second reactor compartment which is anaerobic. A portion of the effluent is then permanently redirected to the septic system to improve the removal of nitrogen released by nitrogen gas. At the end of biological reactor, after a retention time of more than 48 hours, the effluent can be infiltrated into the soil through a field of polishing, be poured directly into a watercourse continuous flow (when conditions permit) or even be reused for irrigation purpose, as a result of a tertiary treatment disinfection. The system is fitted racking sludge, without having to remove the media event that the operation is necessary. |
