Dosing inhibition device role: mineral water equipment to prevent insoluble salt in the reverse osmosis membrane surface scaling.
Softening is the use of ion exchange resin and water in the calcium and magnesium plasma exchange, the water calcium and magnesium ions removed. The advantage of softening is that the calcium and magnesium ions in the water can be completely removed to avoid the fouling of the ions in the reverse osmosis device. The disadvantage is that the equipment investment is high and the regeneration needs to be carried out after running for a certain time.
Addition of scale inhibitors can delay the growth of the salt crystals to delay the precipitation process, using this method can also prevent reverse osmosis fouling pollution. However, due to calcium and magnesium ions still exist in the water, reverse osmosis water than the use of calcium and magnesium ions to be higher, and the way the use of dosing control easier to automate control, and the equipment is simple and low cost. In addition the use of scale inhibitors can also reduce the silicon precipitation, and softening is not, which is very suitable for groundwater treatment. Softening facilities, the cost and flow is proportional to the scale of the cost of adding facilities and flow of little relationship, therefore, two-stage reverse osmosis and device system, the use of scale inhibitor to add the system Precision filter, also known as security filters , Its role is to retain the raw water particles greater than 5 microns to ensure that the reverse osmosis membrane is not large particles of suspended solids scratches.
Because the thickness of Dow reverse osmosis membrane is about 10 microns, the larger particles in raw water by the high-pressure pump can easily scratch the reverse osmosis membrane surface desalination of the epidermal layer or may penetrate the reverse osmosis membrane components, which generally reverse osmosis 5 micron precision filter is required before installation. The use of precision filters on the water remaining suspended solids, non-straight particles and colloidal substances such as removal, RO RO equipment to run more secure and more reliable.
After the above-mentioned treatment of water to achieve the reverse osmosis membrane of the water standard, the water under pressure, the water through the reverse osmosis membrane to become pure water; water impurities were reverse osmosis membrane was seized and concentrated out, the use of anti- Penetration technology can effectively remove inorganic salts in water, colloid, bacteria, viruses, bacterial endotoxin and most organic impurities. Reverse osmosis system desalination rate is generally 95-99%. A reverse osmosis equipment on-line monitoring of water conductivity is generally between 1-10us. The pure water produced by the indicators have reached the national standard of drinking water GB17323.
UV sterilization (optional) to kill bacteria produced by the secondary pollution of water to ensure complete health indicators.
