Reverse osmosis water purifier is currently one of the most effective technologies for removing soluble pollutants in water. The RO membrane has a very small pore size and can intercept ferrous ions and trivalent iron in the water. Use a RO water purifier can effectively remove iron from the water.

Common water filtration media are: 1. Activated carbon 2. Sand filtration and gravel filtration 3. Ceramic filter element 4. Ion exchange resin 5. Ultrafiltration membrane 6. Reverse osmosis membrane Emerging water filtration media are: 1. Graphene membrane 2. Biofilter

Reverse osmosis (RO) technology is usually used for the recycling of water in industry. RO technology is a highly efficient water treatment method that removes impurities and particles from water through a semipermeable membrane filter.

First, it improves the production efficiency and product quality of enterprises and enhances their competitiveness; second, it saves water costs and reduces production costs; third, it meets environmental protection requirements and enhances the social responsibility image of enterprises.

Industrial ultrafiltration involves the use of membranes to remove suspended solids, bacteria, viruses and other contaminants from water. These membranes act as molecular sieves, allowing only water and selected dissolved molecules to pass through while blocking larger particles.

5 industrial uses for ultrafiltration systems 1. Printing and dyeing wastewater 2. Papermaking 3. Oily wastewater 4. Heavy metal wastewater 5. Food wastewater and other fields

Hollow fiber membrane is a porous membrane with a honeycomb-like structure. This membrane is composed of a series of fine hollow fibers with a pore size at the nanometer level. It is usually able to filter out particles such as bacteria, viruses, suspended solids and organic matter in the water, thereby achieving water purification and filtration.
