Reverse Osmosis (RO) Water Treatment Equipment

Reverse osmosis equipment (also known as reverse osmosis) first processes raw water through a fine filter, granular activated carbon filter, compressed activated carbon filter, etc., and then pressurizes it through a pump. Using a reverse osmosis membrane (RO membrane) with a pore size of 1/10000μm, it converts high-concentration water into low-concentration water. At the same time, it completely isolates a large number of impurities mixed in the water, such as industrial pollutants, heavy metals, bacteria, and viruses, thereby achieving the purpose of desalination and producing extremely pure water.

It is mainly used in power plant boiler makeup water, ultra-pure water treatment in electronics and semiconductor industries, pure water treatment in chemical and pharmaceutical industries, food, beverage and drinking water treatment, seawater and brackish water desalination, metallurgy, light industry, advanced wastewater treatment, electroplating, leather and other industries, and has been widely applied.

The water quality varies by region, and the influent water for reverse osmosis equipment also differs, including groundwater, tap water, seawater, and other water qualities. Therefore, influenced by water quality, the pretreatment systems of reverse osmosis equipment also vary.

The pretreatment system of reverse osmosis equipment mainly includes pretreatment filtration equipment such as raw water pumps, dosing devices, quartz sand filters, activated carbon filters, and precision filters. The main role of the pretreatment system is to reduce the pollution index, residual chlorine, sediment, and large-particle impurities in the raw water to meet the influent requirements of the reverse osmosis equipment. Of course, the designed pretreatment systems differ according to different water qualities and requirements. If the water quality is poor, superimposed filters can be used. These are common pretreatment systems in general reverse osmosis equipment, but different pretreatment schemes are still formulated according to different water qualities.
