Double Pass RO Systems
Double Pass RO Systems
Chunke Reverse Osmosis water treatment system can be customized as regards to application. Some industry need very high grade purity for permeate water.
Our solution for high grade purity double pass ro system and if it is necessary electrodeionization water treatment system.
Double Pass RO system has pretreatment section, raw water first enter the pretreatment than goes to ro membrane, at first pass we get pure water called as permeate and concentrated water. To reduce TDS more, we send first pass permeate to second ro membrane and water becomes more pure.
DOUBLE PASS RO SYSTEMS
Chunke as reverse osmosis industrial water treatment equipment company applies different solution for different industry. Especially, pharmaceutical industry , energy&power industry, electronic industry, car industry, water treatment food processing industry, beverage industry need very clean, pure and safe water.
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 membrane and pump, double pass industrial water purification system price is higher than normal system.
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 by 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 recycle).
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.
