Primary Sludge Pumps | What you Should Know
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.
The City of Meridian has utilized ball check technology for years to help move tough sewage and sludge. Ball check technology enabled pumps have moved trillions of gallons of raw sewage worldwide for over 50 years and is the back bone of Wastecorp’s plunger pump, profe
A New Direction in Plunger Pumps: Sludge Pumping Capabilities With A Cleaner Design
When consulting engineers’ and facility operators begin to plan an upgrade for their sewage treatment plants most are considering four primary pumps: Plunger pump technology, rotary lobe pumps, progressive cavity and double disc pumps.
How to Pump Wet Wipes and Cooking Oil
In North America, municipal wastewater treatment operators routinely voice their concerns to Wastecorp about the use of wet pipes by the general public and then flushing them down the toilet. “Do you guys make a pump that can better handle the wet wipes” is a question Wastecorp frequently receives at our sludge pump call centers. Jim K. from Winston Salem North Carolina tells it like it is:
Pump Stations for Expanding WWTP’s
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.
Pumping Wastewater in Nassau County
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 several 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.
Wastecorp worked with local Long island public works contractor Phillip Ross Industries to design, manufacture and install a read more
How to Change The Disc Assembly on A Double Disc Pump
When Wastecorp designed the Sludge Pro Double Disc Pump we set out with the goal to engineer the easiest to service sewage pump available to engineers and WWTP end users. One common request from the engineering community was that an operator or maintenance person would never have to crawl under a double disc pump with a casting hanging overhead and the potential for sewage to leak over the operator. When you think about – why would anyone design a pump like that? Our answer is that you would have to ask the competitor because Wastecorp would not.
The video below shows how to change the trunnion on a Sludge Pro double disc pump. As you can see most of the maintenance is done with the operator standing up and most components visible to the operator.
Safety First
Changing the disc assembly on a Sludge Pro double disc pump is a simple process which can usually be done within 30 minutes
Orange County Waste Acceptance Facility Looks for Pump Solutions
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.
Working with Wastecorp, the company decided on a Sludge Master PE 942 with a 20 hp motor and mechanical force feed oile
Primary Sludge Pumps at a WWTP
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 to install a more robust pump model with features like ball check technology to manage varying solids percentages or abrasive solids. These pumps typically cost a bit more to begin, but the spare parts costs are much lower down the road. Examples of such pumps are plunger pumps, double diaphragm pumps and double disc pumps.
Sludge Handling Equipment Improvement Project – Municipal
When Wastecorp works with consulting engineers and operators on sewage treatment plant improvements, we look to limiting the footprint inside the plant due to the
Engineering Students Learn About Advanced Pump Technology
Wastecorp was glad to see so many engineering students focusing on pump technology at WEFTEC in Los Angeles. The great thing about meeting these students is that Wastecorp did most of the listening.
