CONVERSION
As to our estimations, the number of out-of-date and inefficient sewage purification systems of America and Western Europe is making over 20%. What concerns Russia, due to more severe climatic conditions, constant breaks in power supply, poor maintenance, - more than 80% of sewage works do not function or do not provide the sufficient purification level. Since the technological designs of RSRI APS will provide, alongside with small capital investments for conversion, high and stable sewage purification quality, reduction of power consumption for the capacity range between 100 and 100,000 m3/day - 3-4 times, 25-50% cut in the number of the personnel, the majority of the existing works will be reconstructed in accordance with the proposed designs. The first CWs in Severino Settlement of the Krasnodar Territory were started up on April 29, 1985. The vessels of the aeration tanks out of operation (those meant for prolongated aeration) were used for their construction. The settler reservoirs, as well as those of the aerotanks and pumping stations, can be applied as the basis for a CW. Meanwhile the works capacity can be enhanced 1.5-4 times.
At the moment we are finishing the conversion of 1,500 m3/day biofilters in the village of Starodub of the Bryansk Region for 6,000 m3/day CW.
Before conversion:
After conversion:
We have started converting aerotanks of 5,000 m3/day capacity for 20,000 m3/day CW in the city of Kineshma. A sewage pumping station (D=9m) in the city of Barnaul has already been converted for CW. The above-mentioned SPS houses now a pumping station and CW together with sewage deep treatment works of 250 m3/day capacity.
