Raw water pretreatment system
Pretreatment system of reverse osmosis water treatment equipment is usually composed of quartz sand filter, activated carbon (AC) filter and polypropylene fiber (PP) filter. As to high hardness of the raw water, the water treatment machine has to be also equipped with water softener which is filled with softening resin. PP filters can be efficient in removing above 5 µm mechanical particles impurities in the raw water,rust and large colloidal material pollutants, protecting subsequent filter, it has the characteristics of absorbing large amount of pollution substances and low price. AC activated carbon filter can be efficient adsorption of residual chlorine ,part organic matter, colloid, protect the polyamide reverse osmosis composite membrane from residual chlorine oxidation. Quartz sand filter can effectively remove the suspended, colloid, iron, organic matter, pesticides, manganese, beacteria, virus etc. pollutants in the water. Softening resin can remove the most of the raw water calcium magnesium ions, prevent subsequent RO membrane surface scaling and blocking, improve the recovery rate of water.
Reverse osmosis purification system
Reverse osmosis (abbreviation RO) is a new membrane separation technology of the pressure difference as driving force, with high degree of separation, simple and efficient characteristics. Reverse osmosis membrane "aperture" is small to nanometer (1 nm = 10-9 m),scanning electron microscopy can’t see any small “filter” holes at the surface. When the operation pressure is higher than the osmotic pressure of raw water, water molecules can go through the RO semipermeable membrane, produce pure water, however, a large amount of inorganic ions, organic matter, colloid, microbe and pyrogen are withheld from RO membranes.
