The regeneration process of the related water treatment equipment to remove the hardness of the ionized water treatment equipment is divided into four parts, namely, small backwash, water discharge, regeneration, and normal washing. With rich production experience, we are a technical service provider dedicated to providing engineering equipment and solutions for the biological, chemical, textile, printing and dyeing industries. It can remove calcium and magnesium ions in the water and soften the water.
The water treatment equipment is sodium ion exchanger water treatment equipment, and ion exchanger water treatment equipment is divided into: sodium ion exchanger water treatment equipment, yin and yang bed, mixed bed and other types.
The shell of ion exchange column (device) generally adopts hard polyvinyl chloride (PVC), hard polyvinyl chloride composite glass fiber reinforced plastic (PVC-FRP), plexiglass (PMMA), plexiglass composite transparent glass fiber reinforced plastic (PMMA-FRP), steel lining rubber ( JR), stainless steel lining rubber and other materials. Mainly used in boiler, thermal power station, chemical industry, light industry, textile, medicine, biology, electronics, atomic energy and pure water treatment pre-treatment, industrial production requires hard water softening, deionized water preparation, and also used in food Decolorization and purification of drugs, recovery of precious metals and chemical raw materials, treatment of electroplating wastewater, etc.
plexiglass ion exchange device is corrosion-resistant, colorless and transparent, suitable for small-scale pure water preparation in food, medicine, sugar and electronics industries. The carbon steel rubber-lined ion exchange device has the characteristics of large water production, high strength and low cost, and is suitable for large-scale boiler softened water and large-scale pure water preparation.
Four basic processes of water treatment equipment regeneration
Small backwashing: the purpose is to clean the suspended debris in the pressure grease layer. When the anion and cation exchanger water treatment equipment is set behind the reverse osmosis, because the water inflow is very clean, it does not need to be performed every time, and it can run ten times. Perform a small backwash after the second.
Drain the water: the backwash water is discharged into the water treatment equipment of the exchanger, and discharged from the upper part of the water treatment equipment of the exchanger. It usually takes 10-15 minutes to backwash until the effluent is clear. Open the valve and let the water out of the pipe until it is in the pipe. Until no water.
Regeneration: Sodium hydroxide is fed into the water treatment equipment, and the regeneration liquid flows through the resin layer from bottom to top at a speed of about 5m/h of the flow rate of the empty tower.
Positive washing: Close the drain pipe, open the water inlet valve, and wait for the exhaust valve to discharge water, open the positive washing valve, close the exhaust valve, and carry out the positive washing of the resin. The flow rate is the same as the movement. Until the outlet water quality meets the requirements, open the outlet valve, close the drain valve, and put it into operation.
