Winter in northern climates brings a host of challenges for municipal sewage pumping. With heavy rain and snowfall, America sewage treatment plants must pump through a cycle of runoff and grit in addition [...]
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.
If your marina is looking for a compact dock side pump out station this season check out the ultra compact Mud Sucker Marine pump out system. The best part about this system is that it was completely engineered with marina operator input. We asked marinas what new pump out products would most benefit their boaters and the facility.
One of the best ways to pump out boats ranging from 22’ all the way up to 200’ ferries and commercial vessels is by using a vacuum pump. The higher suction power can pump disposable wipes and other solids found in septic waste relatively quickly so that the next boat can be serviced.
Any wastewater treatment plant operator will typically tell you that one of the biggest hassles they face daily is pumping stringy material from a variety of sources. The problem here is that the material tends to get stuck in the impellers of trash pumps and wreak havoc on lobe pumps. Phil H. from Clyde, Texas tells us about his quest to find a better solution
Our latest Wastecorp trash pump sewage lift stations have hit the market with two to four unit pump models available. Whether you need to replace your above ground, below ground, pre-engineered or auto-start pump stations there are a number of options available to you. For example, all pre-engineered sewage lift stations can accommodate up to 10" trash pumps capable of pumping up to 3500 GPM.
The first visit to a wastewater treatment plant with lobe pumps was a shocker. $550,000 in replacement parts costs spent over the course of just 3-4 years. My response to the plant operator was, “you haven’t spent $550,000 in plunger pump parts over 30 years” so why is the consulting engineer specifying those types of pumps!”
We have all seen the outside of a double disc pump but rarely do we see what makes the pump actually work. Just to review, a double disc pump is a positive displacement pump that uses a trunnion (elastomer), a disc and a connecting rod to force sewage from the suction side to the discharge side of the pump by creating a vacuum inside the pump body. The valve chambers with the black check valves you see in the photo help to manage higher than normal concentrations of grit and solids in municipal wastewater.
Can a Double Disc Pump Have Ball Valves?
Yes. In fact, ball valve technology is helping to usher in the next era of double disc style pumps. The ball valves help to break up solids and make pumping thicker municipal sewage easier. The ball valves also make it much easier to maintain the pump.
Trash pump stations for expanding wastewater treatment plants are an effective way to transfer secondary sludge and raw effluent. Wastecorp recently designed and manufactured this four pump solution for an expanding community near Canada’s capital (see the video below). These trash pumps feature a 3” connection and each pump is capable of transferring 740 GPM.
