Chunke Reverse Osmosis water treatment system can be customized as regards the application. Some industries need very high-grade purity for permeate water. Our solution for high-grade purity double pass RO system and if it necessary electro deionization water treatment system.
Double Pass RO system has a pretreatment section, raw water first enters the pretreatment and then goes to the RO membrane, at the first pass we get pure water called permeate and concentrated water. To reduce TDS more, we send the first pass to permeate to the second RO membrane and the water becomes purer.
Double pass (or two-pass) refers to further purification of permeate from one RO by running it through another RO. The first RO would be the first pass. Permeate from the first pass is then sent to another RO known as the second-pass RO. The second-pass RO “polishes” the first-pass RO product to yield higher-quality water. Because of using more membranes and pumps, the double pass industrial water purification system price is higher than the normal system. The below figure shows a double-pass industrial water treatment equipment RO system.

The design principles for the second pass are generally the same as for the first pass. However, because of the low concentration of dissolved and suspended solids in the influent to the second pass, the influent and concentrate flows can be higher and lower, respectively than for the first-pass industrial water treatment equipment RO system. Because the reject from the second pass is relatively clean (better quality than the influent to the first pass), it is virtually always recycled to the front of the first pass. This minimizes the waste from the system and also improves feed water quality, as the influent to the first pass is “diluted” with the relatively high-quality second-pass reject.
Recovery of the second pass can be as high as 90% with only 2 stages. This high recovery can be achieved because of the relatively low concentration of dissolved solids in the influent to the second pass. Overall system recovery will be 73% with 75% first pass and 90% second pass recoveries (recovery would be 67.5% without recycling).
A tank is typically required between the first and second pass industrial water treatment equipment systems. This is so that flows can equalize between the passes. However, if the number of first-pass skids is equal to the number of second-pass skids, a tank may not be required.
