Cost estimation and economical evaluation of three

The activated sludge (AS) process is a type of suspended growth biological wastewater treatment that is used for treating both municipal sewage and a variety of industrial wastewaters. Economical modeling and cost estimation of activated sludge processes are crucial for designing, construction, and forecasting future economical requirements of wastewater treatment plants (WWTPs).

How to optimize wastewater dosing - Filtration + Separation

The more suspended solids, fats, oils, greases and contaminants in the process wastewater, the greater the sludge disposal costs. Both the chemical and mechanical water treatment processes should aim to maximize water recovery and ensure that the resulting sludge is as dry as cost-effectively possible to reduce disposal costs.

Polymer costs are lowest when the machinery is running at reduced capacity. Typical polymer conditioning costs for centrifugal dewatering range from $2.65 to $91.15 per million gallons of biosolids processed, with an average of $24 per million gallons. Permanganate adds about $1 per million gallons to the cost of dewatering.
