Concentration of protein extracted from residual activated sludge by membrane ultra filtration
The practice shows that the humus soil activated sludge process can enhance nitrogen and phosphorus removal, improve greatly the sludge dewaterability and realize the odor…
Taking Changchun Shuangyang Wastewater Treatment Plant as example, the controlling methods of activated sludge culture and debugging operation of CAST at low temperature in the winter were introduced.
semi-continuous activated sludge test
Over 300 strains of bacteria have been found in activated sludge.
The batch activated sludge method was used to determine autotrophs maximum growth rate. In addition, affecting factors were also investigated.
batchwise activated sludge treatment system
The foam is caused by the excessive growth of some filamentous bacteria and actinomycetes in activated sludge mixed liquor.
It take about 12 days to succeed in cultivating bio-film using of the method of artificial inoculation with activated sludge, and the removal ratio of COD, NH3-N, gets to 72% and 60%.
anaerobic-aerobic activated sludge technique in phosphorus removal and other complete techniques, and achieves a series of parameters.
Optimization design for nutrients removal process with activated sludge 2D model
The effect of calcium chloride on activated sludge was researched in the Activated sludge process.
Effects of COD on activated sludge anaerobic fermentation system for hydrogen production
The results showed that the glucose-fed aerobic granules could be adapted to the synthetic wastewater, the biodegradation ratio of PAM was 40 times higher than the activated sludge in the same HRT.
Results shows that, start-up by seeding activated sludge from a secondary treatment plant has no beneficial effects. On the contrary, the start-up period are detained.
