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.
Orange county is home to dozens of resorts, hotels and theme parks which generate tens of millions of gallons of wastewater that needs to be treated every year. When an Orlando, Florida renewable energy company earned a multiyear contract to accept waste from local resorts and theme parks, they needed severe duty pumps to transfer thick slurries and solids.
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.

Pumping wastewater in Nassau County NY poses unique challenges. First the county borders Long Island Sound to the North and the Atlantic ocean to the south which can bring variations in both weather and the types of wastewater that need to be pumped. Nassau County is home to over 1.3 million residents with a mix of suburban residents and vacation properties.
The City of Long Beach, New York was impacted by Hurricane Sandy a few years ago. The municipal wastewater treatment plant experienced flooding and equipment damage. An additional challenge is a nearby recreation center that includes a golf center. With golf balls and other debris entering the sewage system, the pumps were requested to manage unexpected solids. Wastecorp was awarded the bid to replace an existing plunger pump to upgrade the existing infrastructure. Since the facility is so close to the ocean, a grinder was also installed to manage storm surge debris that will likely occur in the future. Continue reading
Trash pump stations for expanding wastewater treatment plants are an effective way to transfer secondary sludge and raw effluent. Wastecorp recently designed and manufactured a 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.
These pumps feature several add on options for ease of maintenance and pump protection in the event of a closed valve or blockage in the line. First, the Trash Flow pumps were outfitted with spring loaded check valves and drain kit assemblies to reduce pump downtime during maintenance. The engineering specification called for Ashcroft pressure gauges and tungsten carbide mechanical seals for improved life cycles.
