Effective control of inorganic scaling in a wide range of concentrations
02
Effective control of inorganic scaling in a wide range of concentrations
03
It can effectively inhibit the polymerization and deposition of silicon, and the concentration of SiO2 in concentrated water can reach 290.
04
Can be used in reverse osmosis CA and TFC membranes, nanofiltration membranes and ultrafiltration membranes.
05
Excellent solubility and stability.
06
Effective in feed water PH value within 5-10 range.
APPLICATION
Reverse osmosis scale inhibitor is suitable for various types of reverse osmosis systems, including industrial pure water, tap water treatment, seawater desalination, sewage treatment and other fields. The main role of reverse osmosis scale inhibitor is to prevent scale and dirt deposition on the surface of reverse osmosis membrane, thus improving the desalination efficiency of reverse osmosis membrane, reducing membrane clogging, and extending the service life of reverse osmosis membrane.
1. Industrial water production: reverse osmosis scale inhibitor can be used for scale inhibition and cleaning in the process of industrial water production, in order to improve the service life of reverse osmosis membrane and desalination efficiency, applicable to electronics, semiconductor, photovoltaic, chemical, pharmaceutical and other fields.
2. Tap water treatment: reverse osmosis scale inhibitor can be used for membrane scale inhibition and cleaning in the process of tap water treatment to improve water purification and protection of reverse osmosis membrane, applicable to urban water plants, industrial water supply and other fields.
3. Seawater desalination: reverse osmosis scale inhibitor can be used for scale inhibition and cleaning in the process of seawater desalination to improve the desalination efficiency and stability of seawater desalination system, applicable to seawater desalination plants.
4. Sewage treatment: reverse osmosis scale inhibitor can be used for scale inhibition and cleaning in the process of sewage treatment to improve the desalination efficiency and stability of sewage treatment system, applicable to municipal sewage treatment plants, industrial wastewater treatment and other fields.
HOW TO USE?
Dosing method
Reverse osmosis system generally has a special automatic dosing device, consisting of dosing tank, metering pumps, etc., can be set to add the amount of drug per unit of time, continuous addition.
1. The first dosage should first clean the dosage tank.
Sin when closing the bottom of the dosing tank sewage valve, fill the water to clean and open the sewage valve to drain the water, Sin two times after the start of dosing.
2. Adjust the metering pump dosing stroke
Turn the metering pump stroke adjustment knob counterclockwise to the corresponding scale.
3. Dosing
Check and close the drain valve at the bottom of the dosing tank, calculate the amount according to the effective volume in the dosing tank and the actual working force of the metering pump. From the dosing tank adding port to add chemicals, open the water inlet valve to dilute to the highest level scale, close the replenishment valve.
4. open the dosing tank mixing motor, mix the chemicals evenly, stop the motor.
5. open the metering pump inlet and outlet valves, open the metering pump switch, add the agent in the security filter before the RO shutdown, shut down the metering pump.
6. Regularly inspect the dosing system for leakage, and solve the leakage in time. Check the metering pump dosage is accurate, dosing tank level drop and metering pump calculated to join the amount of consistency, if not consistent with the timely calculation and adjustment.
7. the monthly record check cycle total water intake and dosing volume is matched.
8. dosing tank refill water, pay attention not to exceed the highest level.
9. the dosage tank is set to have a low level alarm, the central control PLC if set to a low level alarm after stopping the dosage pump and switch to a spare dosage tank and metering pump dosage. When configuring solution for the second time, the volume of the dosing tank is calculated by the actual volume.
Precautions for use of scale inhibitors.
1. When filling in reverse osmosis inhibitor, you can use a specific medicine box. This medicine box can be used to add medicine to water according to a certain proportion of time agent.
2. It is generally used to fill the filter with reverse osmosis inhibitor. The dosage of the drug depends on the flow size of the reverse osmosis device.
3. Anti-Osmotic scale inhibitor can prevent reverse osmosis membrane fouling and reduce the pressure of equipment. If the medium water impurities are not treated with a scale inhibitor. It can affect the life of the reverse osmosis membrane and even the normal operation of the equipment.
