The details of the project called on the requirement of pumps to transfer ground up seafood shells, grease trap waste, utensils, animal renderings, wastewater and more. In this application, the waste is unloaded from a tanker into a waste pit. The waste is then transferred to a conveyor system which then separates most of the foreign objects like utensils, large solids, plastic bags and more. The remaining waste is sent through the Sludge Master plunger pump and then to the digesters of the wastewater treatment plant. With millions of people visiting Orlando resorts and theme parks every year, this amounts to a lot of waste, as tanker trucks deliver new loads of slurry like liquid waste around the clock.

“We recently specified your Mud Sucker Diaphragm Pump for one of our client’s projects. The contractor must now provide a continuous flow, as much as possible. While this is a solids handling pumping application, the client frequently has to pump thinner fluids. He has found that there is “jerking in the hose” for lack of a better term when pumping thinner water like consistency. What do you recommend as a solution for this issue.” Thanks – Josh M. Sacremento, CA
Josh, pulsation dampeners are a time tested solution for many continuous flow issues pump operators have. Wastecorp manufactures air chambers for every diaphragm pump model we sell. While we prefer to specify these with the pump at the design stage, there is no problem in sending these for contractor installation for the current set up. All we need are some photos of the existing application configuration and we can go from there.
Positive displacement pumps by nature, generate a pulsating flow. When the ball flapper valve opens and closes, the momentum of the liquid reacts in the form of water hammer, which is absorbed by the hose or pipe. By installing a pulsation dampener, it will act as surge suppressor and reduce turbulence in the pipe. The increased volumetric expansion and absorption of the fluid results in a substation reduction of water hammer, as the below graph illustrates.

Primary sludge pumps are typically used in municipal Wastewater treatment facilities to transfer digested sewage and sludge. This is a broad pump category that encompasses positive displacement pumps to pump sludge in ranges usually up to about 500 GPM. The choices of pumps vary from double diaphragm pumps, plunger pumps, double disc pumps, rotary lobe pumps, progressive cavity pumps and more.
In todays pump marketplace, there are generally two schools that operators and consulting engineers follow when specifying primary sludge pumps. The first option is Continue reading
With tough sludge pumping applications like those found at municipal Wastewater Treatment Facilities, (WWTP’s) having the right primary sludge pumps can help reduce hassles and your spare parts budget down the road. This was just the case for the City of Meridian’s recent wastewater treatment facility upgrade and expansion in Meridian, Idaho.
