Three main problems of desalination: Issue 1 Environmental impact ● Brine discharge ● Use of chemicals ● Long-term impact on marine ecology Issue 2 High energy consumption ● Scale of energy consumption ● Energy sources and environmental impact ● Restrictions on renewable energy Issue 3 Economic cost ● Initial investment and operating costs ● Water prices and economic feasibility ● Funding and resource allocation

The main types of water treatment plants are: 1. Drinking water treatment plants, 2. Sewage treatment plants, 3. Industrial water treatment plants, 4. Seawater desalination plants.

Small household desalination plants are suitable for households on remote islands or coastal areas, and the water production capacity is usually 100 to 500 liters per hour. Such plants are relatively affordable, generally between US$2,000 and US$10,000.

As global water shortages become increasingly serious, containerized desalination has attracted much attention as an emerging seawater desalination technology. It has flexible mobility and convenient deployment characteristics, and is suitable for emergency water supply, remote areas and temporary occasions.

Ocean Water Desalination Plants are using reverse osmosis water purification technology. Chunke is leading SWRO Plant Manufacturer in China.
