Application of pumps in water treatment industry
Pumps play a vital role in the water treatment industry, and their applications are wide and indispensable. The following are the main applications of pumps in the water treatment industry:
1. Water transportation and circulation
Pumps are key equipment in the water treatment process, capable of transporting water from one place to another, such as from the raw water tank to the reaction tank, filter or reuse water tank. This transportation capacity ensures the continuity and efficiency of the water treatment process. In addition, in the water circulation system, the pump continuously circulates the water so that the water treatment agent or medium can be fully mixed with the water to improve the treatment effect.
2. Pressure increase and filtration
In the water treatment process, pumps are often used to increase the water level and pressure so that the water flow can overcome the height difference or be transported to the treatment unit over a long distance. For example, in the reverse osmosis (RO) system, the hydraulic pump generates high-pressure water for the reverse osmosis membrane process, forcing the water to pass through the semi-permeable membrane to separate the pure water from the impurities. In addition, in the filtration system, the pump provides the necessary pressure to drive the water through various filter media, such as sand filters, multimedia filters, etc., to remove suspended solids, sediments and particulate matter.
3. Chemical Delivery and Mixing
During the water treatment process, various chemical agents, such as coagulants, flocculants, and fungicides, are usually added to improve water quality. The pump is responsible for delivering these agents in this process and ensuring that they are evenly distributed in the water to improve the treatment effect. For example, during the mixing and stirring of the agents, the pump provides the flow and pressure required for circulating water and mixing chemicals, which helps to homogenize and disperse the additives or reactants.
4. Sludge Treatment and Dewatering
In water treatment systems, sludge treatment and dewatering are important links. Pumps are used in sludge dewatering systems, such as belt filter presses or centrifuges, to provide the pressure required for sludge dewatering and removal of excess water, thereby producing more manageable and smaller sludge for disposal.
5. Emergency Water Supply and Safety Assurance
In emergency situations, such as fires or safety accidents, pumps can provide reliable water supply to ensure the normal operation of fire protection systems or safety facilities. The necessary pressure and flow rate it provides can quickly transport water from dedicated storage tanks or external water sources to where it is needed.
