Choosing chemicals for wastewater sludge dewatering at small-scale wastewater treatment facilities

Summary

The results of studying the effect of introducing cationic Ultraflok K370 and Ultraflok K390 flocculants with different doses and concentrations of the chemical solution on the efficiency of dewatering aerobically stabilized excess activated sludge in a dehydrator at the wastewater treatment facilities of a cottage village in the Novosibirsk Region are presented. It has been established that Ultraflok K390 flocculant with a 0.1% solution concentration and a flocculant dose of 3.8–4.4 kg/t of dry matter is the optimal chemical for sludge dewatering in a screw dehydrator providing for reducing the sludge moisture content to 81.4–81.7%. Increasing or decreasing the dose and concentration of flocculant solutions results in an increase in moisture content up to 82.1–92.8%. The use of Ultrafloc K370 flocculant provides for achieving 83–84% sludge moisture content at 0.2% solution concentration and chemical dose of 3–3.4 kg/t of dry matter.
