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

For areas with complex water quality, such as high heavy metal content or more organic pollutants, reverse osmosis systems are the best choice. Its high-efficiency filtration capacity can ensure water quality safety, but you need to pay attention to its wastewater ratio and maintenance costs.

For seawater treatment needs of a home or small community, an integrated reverse osmosis system is usually the best choice. This system is small in size, simple to operate, and can directly convert seawater into drinking water, which is suitable for home or small-scale users.

The 2 cubic meters/hour reverse osmosis water treatment system is not suitable for ordinary families due to its high processing capacity and complex installation and maintenance requirements. For most households, a small reverse osmosis system can meet daily purified water needs。

The 18000LPH seawater desalination reverse osmosis system has a certain intersection between commercial and industrial use, but is more suitable for commercial use. Its processing capacity is sufficient to meet the water needs of commercial facilities such as large hotels, resorts, ships and islands

Assuming you buy a $300 distiller, the average annual operating cost is $280.8 in electricity + $150 in maintenance + $2.4 in water (based on the highest estimate), a total of about $433.2.

seawater desalination is also one of the important application areas of RO technology, especially in areas with scarce water resources and coastal cities. Through the reverse osmosis system, salt and other impurities in seawater are effectively removed and converted into drinkable fresh water.

The following situations may occur when the reverse osmosis membrane does not work: 1. The water output decreases sharply 2. The water quality deteriorates 3. The system pressure increases 4. The energy consumption of the equipment increases 5. The water treatment process is unstable

The process flow of a desalination plant is usually divided into 5 steps: 1. Seawater intake 2. Pretreatment 3. Core desalination process 4. Post-treatment 5. Concentrate discharge
