Wastewaters treatment plant «Crystall-BIO»

Wastewater is supplied to the treatment plant with the sewerage pumps, placed in the sewerage pumping station or in the balancing tank. The first stage of wastewaters treatment is mechanical treatment to remove large impurities of organic and mineral origin, fibers and particulate pollutants. The second stage is the biological wastewaters treatment using the prolongated aeration technology. The bioblock is built based on the cylindric steel reservoirs (RSS), aboveground containers of full factory readiness or underground cylindric polymer reservoirs. The third stage of wastewaters treatment is the separation of active sludge and treated water and formation of circulating and excess active sludge flow in the secondary tanks. Treated wastewater is disinfected before discharge. Excess active sludge, separated in the secondary tank is sent for dewatering under natural conditions (sludge fields) or mechanical dewatering. All process pipelines and shut-off and control valves within the scope of the treatment plant are in the delivery set of the manufacturing factory.
