1. Classification of water treatment equipment

Water treatment equipment by category can be divided into sewage treatment equipment, raw water treatment equipment, water purification equipment, filtration equipment, ultra-pure water equipment these several categories.

2. Working principle of water treatment equipment

RO- reverse osmosis pretreatment process mainly consists of activated carbon and fine filtration. Osmosis is a natural phenomenon in which water passes through a semi-permeable membrane from the low solute concentration side to the high solute concentration side until the solvent chemical potential is in equilibrium. At equilibrium, the pressure difference between the two sides of the membrane is equal to the osmotic pressure. This is Osmosis effect (Osmosis) phenomenon. Reverse osmosis means that if the high concentration of pressure on the side, it can stop the above mentioned osmotic effect and reverse, so that the water from the high concentration to the low concentration side, the water purification. This phenomenon is called reverse osmosis (reverse osmosis) and this semi-permeable membrane is called reverse osmosis membrane.

Three, nanofiltration water treatment equipment characteristics

Reverse osmosis water treatment equipment can filter out bacteria, viruses, heavy metals, pesticides, organic matter, minerals and heterochromatic odor in the water, is a kind of pure water, without heating can be drunk. The cost of the water it filters is very low. The pure water produced has high quality and ideal sanitary index. Reverse osmosis water treatment equipment is the use of advanced reverse osmosis desalting technology to prepare deionized water, is a pure physical process preparation technology. Reverse osmosis pure water unit has the advantages of long-term uninterrupted work, high degree of automation, easy operation, long-term stability of effluent quality, no pollutant discharge, low cost of pure water production and so on. Reverse osmosis membrane technology has been widely used in domestic medicine, biology, electronics, chemical industry, power plant, sewage treatment and other fields.
