Deep well water demineralized water system,Deep well water demineralized water plant
A. Deep well water demineralized water system General design steps
1. Water quality analysis of water source
2. Design a reasonable and effective pretreatment scheme for the water source
3. Design reasonable reverse osmosis membrane system according to water yield and water quality requirements
4. If higher water quality is required, design post-treatment part (such as mixed bed treatment and EDI treatment system)
5. Design a reasonable chemical cleaning system (large system)
6. For large system, design pilot test system to verify design parameters

C. Deep well water demineralized water system with The basic principles of reverse osmosis
RO(reverse osmosis)referred to as RO.is under pressure from.so that certain componets of the solution selective.so as to achieve desalination.purification or enrichment of a separation of the purpose technology used in the treatment process,which can remove most of the fine particles in the water,but also can remove bacteria and organic matter in water and other imprities.is the depth of water quality prification of an advanced and conomicalmeans Reverse osmosis membrane in 0.1A of the aperture about operating pressure genrally above 1.0Mpa Reverse osmosis membrane for all and any soluble salt of molecular weight greater than 100 organic and inorganic molecules have a high removal rate. but the water molecules are able to pass throuht reverse osmosis membranes Reverse osmosis membrane for the removal of salt water in 95% of the general.up to 99%.
