Ultrafiltration ancillary equipment
First, booster pump
1, the ultrafiltration membrane to force the difference as the driving force to filter, when the water pressure of raw water can not meet the filtration needs, the system needs to increase the pump pressure to achieve ultrafiltration membrane separation, the ultrafiltration membrane work pressure is low,
Generally less than O.7MPa, so the system design, the general use of centrifugal pumps, centrifugal pump is the main basis for the choice of head, flow, pump material, followed by the size of the pump size, appearance and price.
2, according to the ultrafiltration system design required for the water pressure, transmembrane pressure and water flow, to select the pump head and flow. General choice of pump head and flow should be equal to or slightly greater than the design of water supply and working pressure to meet the normal operation of ultrafiltration system.
3, according to the raw water quality of the situation to select the appropriate pump material to reduce the cost of investment, the material can not produce any reaction with the raw water, can not have dissolved phenomenon.
When the raw water pH value of 6.5 to 8.5 when the cast iron pump body; when the raw water for the sea, should be selected for seawater corrosion of plastic pump; medicine and food industry water treatment is generally chosen to use stainless steel pump body.
Chemical cleaning pumps generally choose chemical-resistant pumps.
Hangzhou Shuidun Technology is specialized in the production and development of stainless steel water treatment products with high quality and resonsable price, it is the preferred product of reverse osmosis water treatment works. Welcome for an inquire.
