Selection of water pumps for food processing wastewater treatment
In the treatment of food processing wastewater, the selection of water pumps is a crucial link. The following are some detailed suggestions on the selection of water pumps for food processing wastewater treatment:
1. Selection of water pump types
The types of water pumps that can be selected for food processing wastewater treatment are mainly centrifugal pumps, plunger pumps, screw pumps, acid and alkali resistant tank vertical pumps and sewage treatment pumps.
Centrifugal pumps: simple structure, large flow, high head, stable operation, is a commonly used type of water pump in food processing wastewater treatment.
Plunger pumps: suitable for occasions requiring higher pressure and smaller flow. If there is such a demand in food processing wastewater treatment, it can be considered.
Screw pumps: have the advantages of a wide range of conveying medium viscosity and good stability. They are suitable for conveying occasions containing solid particles or viscous liquids, and are suitable for treating food processing wastewater containing certain solid particles.
Acid and alkali resistant tank vertical pumps: suitable for treating corrosive wastewater, such as wastewater generated after the production of certain food additives.
Sewage treatment pump: specially designed for conveying corrosive media containing fine particles or crystals, with excellent corrosion resistance and excellent wear resistance, suitable for food processing wastewater treatment.
2. Determination of performance parameters
When selecting a water pump, it is necessary to determine the performance parameters according to the actual needs of food processing wastewater treatment.
Flow rate: Determine the flow rate of the water pump according to the flow rate requirements of wastewater treatment. The flow rate should meet the requirements of the wastewater treatment system to ensure that the wastewater can be smoothly transported and treated.
Lift: Consider factors such as the conveying height of the wastewater and the resistance of the pipeline to determine the lift of the water pump. The lift should be high enough to ensure that the wastewater can be effectively transported to the treatment equipment.
Material: Choose corrosion-resistant and wear-resistant materials to adapt to the characteristics of food processing wastewater. For example, water pumps made of stainless steel, PP/PVDF and other materials can be selected.
3. Other considerations
Sealing performance: In food processing wastewater treatment, the sealing performance of the water pump is crucial. A water pump with good sealing performance should be selected to prevent wastewater leakage from polluting the environment and equipment.
Stability and reliability: Food processing wastewater treatment requires continuous operation, so the stability and reliability of the water pump are very important. Choosing a well-known brand and reliable quality water pump can ensure the stable operation of the wastewater treatment system.
Maintenance and care: Consider the convenience of water pump maintenance and care. Choosing a water pump that is easy to maintain and has low maintenance costs can reduce the operating cost of the wastewater treatment system.
By choosing a reasonable water pump, you can ensure the stable operation and efficient treatment of the food processing wastewater treatment system.
