Double Disc Pumps and Municipal Sewage Pumping

Double Disc Pump

Double Disc Pump

For years, we have been asking wastewater treatment plants (WWTP) what they like about double disc pumps and what they don’t like. We have even been compiling a database with what regions of the USA and Canada have success with this type of pump for sewage and which areas have had more challenges.

One of the things that most WWTP’s say is that there has been limited competition in the specifications put out for bid by municipalities and consulting engineers working on wastewater projects.  As we all know, a monopoly in the pump industry is seldom a good thing for quality, innovation and of course pricing for pumps and parts. There have also been some stop and starts with competing technology from underfinanced companies trying to knock off the design with “dia-disk” pumps, etc.

The other major suggestion from operators is that double disc pumps have to be able to handle grit and solids more effectively. Otherwise they say, they would rather go with a plunger pump, rotary lobe pump or a progressive cavity pump. Continue reading

Primary Sludge Pumps at a WWTP

Primary Sludge Pumps

Primary Sludge Pump Options

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

Double Disc Pump Comparison: The State of the Double Disc Pump Business

Compare Penn Valley and Sludge Pro Double Disc Pumps

Wastecorp was recently at WEFTEC exhibiting our newest double disc pumps for the municipal wastewater treatment market and industrial fluid handling space. Wastecorp’s Sludge Pro double disc pump marketing program continues to focus on building awareness with WWTP operators and consulting engineers that competition exists in the double disc pump space and the market offers a more robust alternative than traditionally known.

We have noticed that when a double disc pump for a WWTP upgrade or expansion goes to the planning stage and/or bid stage, we get calls from consulting engineers saying that the competition or their pump distributor make misleading or incomplete statements about double disc pump competition. What it boils down to is trying to eliminate competition. In America, we call this an attempt to create a monopoly. History has shown that monopolies are seldom good for competition in the pump business or any other business for that matter. History has also shown that monopolies in the United States aren’t looked at favorably by either regulators or the public. Continue reading

How to Pump Out of Waste Pits

Waste Pit Pump

Waste Pit Pump

Waste pits, sump pits, catch basin, overflow pit, pumping from waste containers are all pump applications that medium and large size facilities have to contend with in the food, manufacturing, chemicals, and septic management industries. Having the right pump and piping arrangement can help you get the job done properly.

We want to walk you through just a few of the critical factors you need to consider when planning your waste pit application. Continue reading

Orange County Waste Acceptance Facility Looks for Pump Solutions

Orange County Sewage Pumps

Orange County Sewage Pumps

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.
