Activated carbon filter

The role of the activated carbon filter is to remove macromolecular organic matter, iron oxides, chlorine. Organic matter, chlorine, iron oxides easy to make ion exchange resin poisoning, chlorine, cationic surface active agent will not only make the resin poisoning, but also destroy the membrane structure, so that the failure of the reverse osmosis membrane.

The active carbon filter is the use of activated carbon having a rich pores on the macromolecular organic matter in the water, chlorine, iron oxide colloid adsorption filter, this absorption is not reversible, i.e., activated carbon saturated adsorption capacity, once saturated adsorption, activated carbon loss of adsorption performance, can not be the backwash method rushed pollutants. In addition, activated carbon adsorption of organic matter, bacteria rich in nutrition, resulting in a large population of bacteria within the activated carbon filter, but increased the microbial content of the water by activated carbon filter.fabric filter

Before activated carbon adsorption saturation, backwash on a regular basis to a large number of bacteria group out of the surface of activated carbon and suspended solids. They should immediately replace it with a new activated carbon, activated carbon adsorption saturation, otherwise it will cause irreparable damage of the reverse osmosis membrane.

Water Softener

The role of the water softener is the removal of calcium and magnesium ions, the water is softened. If no softener or softener VALID, calcium, and magnesium salts in the surface of the reverse osmosis membrane is formed due to a sharp rise in the concentration of the water-insoluble precipitate, plugging the hole of the reverse osmosis membrane, the reverse osmosis membrane life shortened.bag filter manufacturers

Built water softener for ships with a sodium cation exchange resin, the exchange resin is saturated with brine regeneration. Resin degree of fragmentation is getting worse after a few years of use, gradually lose the ability to soften. Especially when the active carbon filter saturation adsorption but not timely replacement of activated carbon in raw water iron, organic matter, chlorine directly into the water softener resin poisoning, poisoning, the resin will not be able to use renewable way to restore activity, , replace the resin when the resin exchange capacity decreased.
