The Sludgemaster – Sludge & Slurry Pump. The Sludgemaster pump is built to pump the most viscous sludges and slurries. Because of its ability to pump thick substances, this pump runs optimally at 55 strokes per minute. At maximum load, the Sludgemaster achieves 250 GPM at 150 PSI. Request A Quote Trash & Water Pumps
The return sludge is returned to the aeration tanks by way of a sludge-lifhng pump which gently raises the sludge without damaging the biologicat floccs. When the settleable solids indicate excess concentration of sludge then quantities of sludge can be wasted from the clarifier by the excess sludge submersible pump which pumps the sludge to ...
Nov 04, 2013· Once the sludge is removed, it is dried and is transported to either a landfill or a land application facility. This is an extremely laborious and costly process. An average cost is around $350 per dry ton of sludge. Many lagoons can easily have as much as 2500–5000 dry tons of sludge stored up (i.e. $875,000–$1,750,000).
Biosolids Technology Fact Sheet Belt Filter Press DESCRIPTION Belt filter presses are used to remove water from liquid wastewater residuals and produce a non-liquid material referred to as "cake". Dewatered residuals, or cake, vary in consistency from that of custard to moist soil. Dewatering serves the following purposes:

The Fayetteville Wastewater Treatment Plant, Tennessee, treats approximately 1.5 million gallons (MGD) of municipal wastewater per day. At the Fayetteville WWTP, action has taken the form of a forward-thinking approach to plant operation and multiple initiatives designed to lower the costs of operation and improve efficiencies.
The power cost per thousand gallons is directly proportional to the cost per kilowatt hour (kWh) and pump head while inversely proportional to pump and motor efficiency. Let's compare the electrical costs for two different pumps. Figures 2 and 3 show the power cost per thousand gallons pumped for two pumps.

Wastewater treatment - Wastewater treatment - Sludge treatment and disposal: The residue that accumulates in sewage treatment plants is called sludge (or biosolids). Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a by-product of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge.
