Seawater desalination technology integrates a variety of water treatment technologies such as nanofiltration, reverse osmosis, electrodialysis EDI, and freezing. In practical applications, reverse osmosis technology is the preferred technology widely used in seawater desalination projects in various countries, and the working pressure is relatively high. In process design, multi-media filters and precision filters are generally required as pre-filtration; high-pressure pumps and seawater filtration membranes are then used. At the same time, concentrated water recovery technology should be added to improve the recovery rate of the reverse osmosis system.

Purified water used in the biopharmaceutical industry is also called deionized water (or desalted water). It usually refers to a type of process water that is prepared by reverse osmosis and other methods, using city tap water or surface water as raw water and does not contain any additives. In terms of process design, a bipolar reverse osmosis system is required, combined with an ultraviolet sterilizer, microporous filter, pasteurization, etc. Automatic control is generally used.

The main purpose of controlling the water quality of boiler feed water is to prevent boiler scaling, corrosion, and salt accumulation. Usually, low-pressure boilers use softened water as feed water; while high-pressure boilers must use demineralized water as feed water. In boiler water treatment, it is generally necessary to add a dosing device and use chemical treatment to remove harmful impurities in the raw water. At the same time, attention should also be paid to the pH value of the water, because water with too high alkalinity can cause alkaline corrosion, pipe blockage, and other problems. In process design, ultrafiltration + bipolar reverse osmosis + EDI; ultrafiltration + reverse osmosis + mixed bed; or ion exchange + reverse osmosis are commonly used.

Most of the drinking water sources in rural areas are river water, mountain spring water, reservoir water, and underground well water. Common problems include turbid and yellow water, a lot of algae, and undrinkable water. Our rural intelligent integrated water purification equipment is a culmination of the essence of flocculation, sedimentation, sewage discharge, backwashing, water collection, and filtration processes. It is a series of water purification devices that can achieve fully automatic operation without human operation. It is an important unit for realizing automated management of water plants. Equipped with automatic dosing devices and disinfection equipment, it can become a water purification station with a full set of functions.
