Sewage pumps in different types of water treatment plants

　　In recent years, the wastewater pumping industry has experienced significant growth, driven by the trend of numerous companies to reduce and recycle the liquid waste generated during the production process.Air operated double diaphragm pumps (AODDs) are essential tools in the process of purification of water contaminated by industrial activities, sludge treatment, filtration of waste products, and separation of solids from liquids.

　　In order to fully understand the critical role of air operated diaphragm pumps in industry, it is necessary to differentiate between the different wastewater treatment processes.Wastewater treatment plants ensure that contaminated water from industrial activities such as refineries, chemical and petrochemical plants is treated to a level of contamination consistent with the requirements for discharge into sewers, watercourses, lakes, and oceans.

　　There are currently four types of water treatment plants

　　Wastewater treatment plants: remove harmful pollutants from wastewater before it is discharged into the environment.

　　Activated sludge plants use activated sludge to degrade biological contaminants in wastewater. This process involves oxygenating the wastewater for an extended period of time so that the biological components can process away most of the organic debris and pollutants.

　　Wastewater treatment plants are used to treat wastewater from highly polluting industries such as pharmaceuticals and chemicals.

　　Shared and combined wastewater treatment plants, which are used to treat wastewater from different sources, combine a variety of treatments to deal with a wide range of pollutants.

　　All these types of wastewater treatment plants ensure that the treated water is suitable for discharge into the environment or reuse.

　　The role of diaphragm pumps in the water treatment industry

　　Double diaphragm pumps are ideally suited to the following stages of wastewater treatment due to their ability to handle a wide range of materials including solid wastes, highly viscous liquids and abrasive materials.

　　In industrial wastewater treatment involving the transfer of hazardous liquids, diaphragm pumps allow for safe and efficient treatment through the injection of acidic or antimicrobial substances.

　　In filtration processes, AODD pumps, with their robust construction and low maintenance requirements, can be used in filter presses to separate solid and liquid components.

　　In wastewater treatment, diaphragm pumps are used to neutralize and treat chemical spills, as well as to remove debris and foam. These pumps help to extract sediments and dispose of debris floating on the surface, effectively contributing to the purification process.

　　In the sludge removal process, double membrane pumps can be used to treat a variety of materials, including thickened sludge, clarified sludge or organic waste. Double membrane pumps safely remove toxic chemicals without posing a hazard to operators, making them a reliable and efficient solution.

　　The materials selected for SHIDEBAO water treatment pumps ensure compatibility with all pH values and can handle strongly acidic or alkaline fluids, a versatility that makes them ideal for different water treatment challenges.
