The Problem With Pumping Sewage & Wastewater
The most common issues are wastewater system pumps being clogged by flushable wipes, baby wipes, and feminine products.
Dealing with a clogged pump or pipe is never fun. When the blockages involve sewage and other forms of hazardous waste, routine cleaning chores can become a health hazard. Keeping sewage pump stations and treatment plants running smoothly not only saves money, but it also results in higher job satisfaction among the maintenance team, in addition, to help keep the city running smoothly.
It’s not just the unusually large size of solids that make sewage pumping and wastewater treatment handling so challenging. The nature of the solids in question also plays a role in the likelihood of the formation of clogs. Sewage from toilet facilities is particularly likely to form clogs due to the use of toilet paper and flushable wipe and feminine products. While most toilet papers break down by the time the material reaches a sewage pump, flushable wipes tend to clump together due to their long, thin shape and tough fibrous texture.
Combine these easy to snag solids with malleable mixtures that act like clay when caught against another item and you can easily understand why sewage pumps can bind up so quickly and completely. Even with care, many sewage pumping stations find themselves replacing their primary pumps annually or even every few months due to the intense amounts of wear and tear on the equipment. If the pumps manage to run for a few years without replacement, it’s usually due to extensive cleaning routines that involve many hours of extra labor per month. Chopper pumps are ideal for sewage processing applications because the internal chopping mechanism breaks up large solids before they reach the pump. Add smaller solids to the large internal capacity of the EDDY pump design and you have a winning combination for avoiding sewage clogs in even the most challenging systems.
Currently, EDDY Pump only deals with municipal and industrial clients, as we focus on heavy-duty and high volume industrial applications.
Commercial Sewage Applications
The majority of sewage pumps are installed at wastewater treatment plants and similar facilities, but they have many other uses. Large facilities like hotels, campgrounds, and amusement parks often rely on these pumps to move sewage to a distant holding tank or far-off sewer connection point. Any bathroom facility located below the sewage connection or septic tank will require some kind of pump to lift the slurry to its intended destination. Receiving stations that handle deliveries from septic tanks and portable toilet trucks also need these pumps to distribute the raw sewage to the various storage or processing areas.
These pumps are also required for other types of sewage that aren’t generated by human sources. The same slurry pumps used for bathroom facilities work well for moving valuable manure slurries around, which often feature solids even larger and more challenging to pump than those found in sewage. Manure processing can yield valuable fertilizer products while protecting local waterways from toxic runoff, but only if the treatment facility has the right slurry pumps for separating and moving the various raw materials.
The Power of the EDDY Pump For Sewage and Wastewater Facilities
EDDY Pump has a tested and multi-decade proven solution. The sewage systems of the US Navy have been using EDDY Pumps for many years. Read about the newest Ford Class using EDDY Pump HERE. Based on the EDDY Pump design which has a large and non-critical tolerance between the rotor and volute, it makes for the ideal sewage pump. The EDDY Pump can pass an object without any issue that is 1-inch smaller than the intake of the pump. For example, a 4-inch EDDY Sewage Pump can handle a 3-inch solid without clogging or having any negative effect on the pump. Another advantage of this extreme tolerance is reduced wear and tear because fewer solids come in contact with the rotor.
The EDDY Slurry Pump isn’t like other pump designs created for sewage handling. Only this pump harnesses the power of the eddy current to create a strong flow and plenty of suction with a small and open rotor. Since there’s no need for the rotor to pass close to the internal walls to generate pressure, very large solids can flow through without getting caught and causing a clog. The EDDY pump’s ability to handle a slurry with up to 70 percent solids and a high viscosity makes it ideal for handling sewage from bathrooms featuring ultra-low flow fixtures. Even with low levels of water, the pump manages to move the same amount of solids of distances up to one mile. With the right pump design, solids of up to 11 inches can pass without clogging the pump. There’s no need to deal with constant unclogging, fussy filters, or regular replacements due to abrasion or corrosion when you choose the EDDY pump.
Optional. A chopper upgrade can be fitted for use in sewage pumping applications. Most other pump applications the EDDY Pump works without comminutors, macerator or grinders because the tolerance is large enough to pass all material without any issues. But for large scale municipal use, we recommend cutter to break down flushable wipes and other non-organics.
Why use a chopper pump? EDDY Pumps can easily pass objects such as large waste and non-organic material on its own, but without a chopper addon, clogs can potentially happen downstream. For sewage applications, we recommend using a chopper addon to prevent clogs in your downstream applications. Call us to discuss.
Conclusion: Cost Reducing Sewage Pump
The EDDY Pump has been utilized by the US Navy for over 20 years on almost all classes of Navy ships for grit, waste transfer and sewage pumping. The reason is that this pump design saves the Navy tens of millions of dollars every year in corrective action, overhaul, and downtime.
