It is the best equipment for high-purity water preparation, brackish water desalination and wastewater treatment processes.
[0003] In the purification of pure drinking water (mineral-free) by existing reverse osmosis water purification equipment, the reverse osmosis treatment process is basically a treatment process combining activated carbon, quartz sand and reverse osmosis. It is easy to cause the reverse osmosis membrane to be blocked during water treatment, and the reverse osmosis membrane needs to be replaced frequently, which increases the cost of use.
