Common Applications of Lime Pumps in Water Treatment Settings


An often overlooked but supremely essential part of any society is the treatment of wastewater and sludge. How is the sewage handled? For more than a century, lime has been the compound of choice for treating wastewater in the Western world. The addition of liquid lime, generally a combination of calcium hydroxide, calcium carbonate, and magnesia suspended in water, is used to neutralise acids and control the pH levels of various forms of liquid waste. In the modern era, the liquid lime is dosed directly to the sludge by use of pumps, piping systems, and mixing tanks. Since there are high levels of fluid viscosity involved and elevated levels of momentum that must be produced for the mixing process to work correctly, powerful pumps that are not prone to leakage or blockage are vital. Time and again, peristaltic pumps have been the lime pumps of choice for various reasons.

Peristaltic pumps, also known as hose or tube pumps, provide abrasion resistance when dealing with a rough compound like lime. The peristaltic action used to pump the liquid, keeps the lime components suspended in the water and doesn't allow them to settle at the bottom (which would hamper their efficacy). Furthermore, the ability of tube pumps to handle solid material means that lime solution can be mixed on-site and doesn't have to be prepared beforehand and transported to the treatment location. This all makes them excellent choices for use as lime pumps in water treatment settings. Global Pumps supplies many high quality industrial pumps for use across various industries.
