The Problem of Space Constraints at Wastewater Treatment Plants

Space Saver Plunger Pumps

Space Saver Plunger Pumps

It’s a common problem faced by many wastewater treatment facilities’, how to select a pump to move heavy sludge with enough power and endurance to last through the long haul.  One solution to this problem is a pump with an in-line piping design like the Space-Saver plunger pump.  Many facilities have seen success with this pump especially those replacing a double disc, rotary lobe, or progressive cavity pump.

The Space saver plunger pump does not require a concrete base, which makes replacing any type of sewage pump quick and trouble-free. In most cases, the old pumps are simply replaced and the new Space Saver simply dropped into place.  The Space Saver is available with a 7”, 9” or 11” piston size and can transfer up to 140 GPM (8.8 lps) of municipal or industrial sludge.

In our case study feature, you’ll see a Memphis, Tennessee area sewage treatment plant which recently installed a Space Saver after trying double disc and progressive cavity pumps.  The facility operates this pump for at least eight hours each day and other than general maintenance procedures, the pumps have run perfectly.

Information Resource About Plunger Pumps

Good news for plunger pumps owners, Wastecorp has launched a website, myplungerpump.com which focuses on the needs of municipal and industrial plunger pump operators. The website includes five sections about plunger pump technology, a positive displacement pump used to transfer sewage and sludge.

Plunger Pump Basics: What You Need to Know
The plunger pump basics section is a helpful resource for new pump operators, consulting engineers, maintenance staff and distributors who are new to the primary treatment side of wastewater treatment.  The section briefly describes how a plunger pump operates, the average life span and more.

Grout Pump Options

Grout Pump In Use

Grout Pump In Use

Grout pumps are one of those tools that are always in need on residential and commercial construction sites but are not readily available at equipment rental shops or Home Depot or Lowes (Not the the professional grade grout pumps anyway). You should be aware that a lot has changed in the world of grout pumps and the availability of them for contractors, do it yourselfers and construction professionals.

First, the grout pumps we are talking about are manual grout pumps or grout pumps operated by hand and air operated grout pumps, grout pumps operated by compressors with air hose lines. Second, we are talking about non-epoxy type generally grout used in the construction industry and grout that flows. Continue reading

How to Plan a Marine Pump Out Station

Marine pump out

Planning a marine pump out station is essential to getting the appropriate  pump out equipment for your marina. Consulting other marinas in your area or a marine pump manufacturer ahead of when you actually need the system installed is your best bet. Wastecorp has generally found that marinas seem to be getting larger boat and yacht traffic in the last few years that need to be pumped out. Don’t forget, since a pump out is part of your business model, you should be charging larger yachts appropriately. This trend is expected to Continue reading

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
