Csm Water Purifier RO Membrane Price

Household reverse osmosis membranes are a range of household reverse osmosis membranes designed to meet the market demand for high recovery and high desalination rate, with high stability and high stability and reliability.

1. New membrane element structure design;

2. Design concept, effectively extending the service life;

3. High precision membrane manufacturing process, effectively reduce the decay of desalination rate under high recovery rate conditions, desalination rate reaches stable state faster, greatly reducing the waiting time.

By using a super static pressure pump to generate high pressure osmosis, water molecules and mineral elements in ionic form pass through a reverse osmosis membrane.

The majority of heavy metals, organic matter, bacteria and viruses dissolved in the water cannot be retained through the RO membrane (the pore size of the RO membrane is only 0.0001um, while the diameter of viruses is generally 0.02-0.4um and the diameter of common bacteria is 0.4-1um).

Suitable for any domestic brand of reverse osmosis RO water purifier.
