Under normal circumstances, the replacement cycle of household reverse osmosis membranes is generally 2 to 3 years; the replacement cycle of commercial and industrial membranes is 1 to 2 years. Common household reverse osmosis membranes cost between US$30 and US$100...

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.

● Water output (Qp): 30,000 liters per hour ● Recovery rate (R): 60% ● Calculate the recovery rate using the formula: Qin = Qp/R ● Substitute the known values ​​into: Qin = 30,000 liters per hour/60% = 50,000 liters per hour

After years of development and application, seawater desalination technology has become increasingly mature, and the effluent water quality is stable and reliable, which can meet the high standards of drinking water and industrial water.

If the local water quality is good and the pollutants are mainly suspended solids and microorganisms, you can choose a water filtration device. However, if the water contains high soluble pollutants (heavy metals, pesticide residues), it is recommended to choose a water purification device.

The reverse osmosis filter passes water molecules through the membrane pores under high pressure through a semipermeable membrane, while pollutants such as dissolved salts, heavy metals, bacteria and viruses are retained on the other side of the membrane to achieve the purpose of water purification.

Israel is one of the most water-poor countries in the world, but it is a world leader in agricultural irrigation technology. In Israel's desert areas, reverse osmosis water filtration systems are widely used to treat seawater and salt water to provide high-quality irrigation water.

According to the characteristics of different pollutants in well water, taking into account the filtering effect, cost and maintenance convenience, these methods are considered to be the best methods for well water filtration. 1. Multi-stage filtration system 2. Biosand filter 3. Ion exchange filter

Equipment required for water treatment 1. Pretreatment equipment 1.1 Grids and screens... 2. Primary treatment equipment 2.1 Coagulation equipment... 3. Secondary treatment equipment 3.1 Biological treatment equipment... 4. Tertiary treatment equipment 4.1 Advanced oxidation equipment...

Reverse osmosis systems use semi-permeable membranes (pore size of about 0.0001 microns) to remove most pollutants from water, including microplastics, nanoplastics, and soluble compounds.
