Inecs company reconstructs active sewage treatment plants.
Highly skilled specialists visit the site, examine the state of water treatment plants and offer the ways of their reсonstruction.
At our web site there is a page describing primatology facility of the Russian Academy of Medical Sciences situated in the Adler region, Sochi, as well as the reconstruction project of the treatment plants for the Institute of Medical Primatology done by Sochi State University of Tourism and Recreation (SSUT&R) before and after reconstruction.
General technology was developed on the base of analysis results of the examination of the Institute’s treatment plants :
1. To provide the flexibility and trouble-free service of the sewage pumping station and operating costs reduction, the sewage pumping station is reconstructed by the means of the inflow system automation, receiving trap and hutch installation for coarse particles, getting into the receiving waste water pit of sewage pumping station. The main and reserve pump is switched on and off according to the water level in the receiving tank.
2. To secure safe operation of the water treatment plants, flow balance unit is planned to be reconstructed. The existing balancing reservoirs are to be reconstructed, they are covered with corrosion prevention mastic. The total volume of the balancing reservoirs is 100 m3. To prevent the settling of suspended solids in the balancing reservoir and to provide full mass exchange in the reservoirs, it is planned to install mass exchange pump with the help of the time switch. The receiving pit is to be overhauled.
3. The reconstruction of the mechanical treatment block is done by the removal from the technology of existing receiving traps and sand traps and installation of the self-cleaning filter unit of Inecs, Ltd, Russia production.
It is supposed to install two self-cleaning filter units of “UFS 1” type at specially equipped ground above the balancing reservoir. “UFS” unit enables to avoid the construction of regulating clarifiers provided in the Sochi State University of Tourism and Recreation project.
4. To increase hydraulic pressure resistance as well as to improve the quality of waste water treatment, the project provides the reconstruction of aeration tank unit based on the recovery of existing aerotank facilities, its cover with hydraulic insulation and cases installation filled with synthetic feed of “Yorsh” type with the system of small bubbling aeration.
5. In order to increase the capacity index of the activated sludge clarifier the project provides reequipment of the existing horizontal sludge clarifier with water flow feed passing through the submerged weir into the vertical one with central water feed. It is also intended to install catch water trays with triangular weir, water drain system and recirculation of surplus active sludge.
6. The project covers biological waste water posttreatment unit. Two metal containers of the dimensions 6,0x3,0x3,0 m each are installed, the containers are covered with hydraulic insulation mastic and charged with cases filled with synthetic feed of “Yorsh” type and regeneration system. Existing containers are not used due to their unavailability. The pipework is assembled for the regeneration solution discharge.
7. The sludge treatment unit is installed based on the aerobic stabilization of the surplus active sludge with the following dehydration at the equipment of Inecs, Ltd production. Aerobic stabilizer-sludge thickener with two taper bottoms and sludge filter “IFG 6” is to be installed.
8. For the intensification of the sludge thickening process, it is supposed to deliver positive ion flocculant into the container of stabilizer-sludge thickener. The unit “Feya” is used to prepare the flocculant. Sludge disinfection is effected by the anti worm remedy substance “Bingsti”, which is dosed to the stabilizer-sludge thickener.
9. The project provides the replacement of the existing system of the treated waste water disinfection with chloride lime for the UV-unit of the channel type, installed directly at the treated waste water discharge tray. The system of waste water disinfection with chlorine substances is considered the reserved version.
10. To provide the technological process with air it is supposed to replace worn out air blowers. The system of air vent for compressed air feed into the aerotanks and into the bioreactor of posttreatment is assembled.
The following units are excluded from the existing waste water treatment technology:
- sand trap of water circulation
- sand and sludge drying grounds
- biological ponds
