How to choose between single stage and double stage reverse osmosis?

I've been getting a lot of inquiries lately, The customer needs reverse osmosis equipment, However, it is uncertain whether a single-stage or two-stage reverse osmosis device is required. Due to lack of understanding, Hence the question. today VLLRO Clean water for everyone to analyze.

Most electronics industries choose two-stage reverse osmosis when flushing water EDI Equipment of, Such as integrated circuit, Electronic components such as silicon wafers and display tubes. Previously, we had a customer in Qingdao, China, who made precision parts for mobile phones, We gave them the advice to use a two-stage reverse osmosis plus EDI equipment. however, In order to save costs, They chose a single-stage reverse osmosis device, As a result, the scrap rate of products is very high. Then they changed to bipolar reverse osmosis equipment, But it didn't work out well. Finally, they decided to use a two-stage reverse osmosis equipment plus EDI, Their production efficiency and the quality of their finished products have been greatly improved. Now it's been three years, Last time I went to the factory to visit the customer, They said they should have followed our advice, Direct selection of two-stage reverse osmosis equipment plus EDI, Instead of tossing and turning, Can save a lot of money~

A two-stage reverse osmosis device utilizes two membrane components, Removes impurities and contaminants from the water more effectively, Provide high quality pure water. Single-stage reverse osmosis devices purify water through a single membrane component, Although the desalting rate is low, But the structure is simple, Low maintenance cost, It is widely used in the field of drinking water purification in families and small commercial places.

Let me give you another example to make it easier to understand: Raw water contains 100 Fractional impurity, After a first stage reverse osmosis treatment, Removal rate is 90%, remaining 10 Fractional impurity. If your requirements are impurities in 20 In part, Then first-level processing can meet the requirements. If your request is 5 Within part impurity, Then we can proceed to the second level of processing, By further filtration, The final residual impurity is 1 Copy of the, I'll meet your requirements.

so, Depending on your water needs, decide whether to use single-stage or dual-stage reverse osmosis equipment, In general, Single-stage reverse osmosis equipment is sufficient to meet the requirements of direct drinking water.

Two-stage reverse osmosis equipment is usually widely used in industrial fields, Such as light textiles, Process water for chemical industry/Chemical circulating water, Chemical product manufacturing, Water for food and beverage industry, beverage, beer, White spirit, Health care products and other preparation water. These industries have high water quality requirements, Therefore, two-stage reverse osmosis equipment must be used.

therefore, When selecting a device, Choose the right equipment for your water needs. If water demand is not high, Single stage reverse osmosis equipment is the best choice. The equipment is small in size, Easy to maintain, Simple operation, The cost is also much cheaper than two-stage reverse osmosis equipment.
