Low Pressure Ro Membrane

Regular RO membranes need high pressure to work. That means you need a big pump. Big pumps cost more money. They also use more electricity. A low pressure ro membrane is different. It needs less pressure to push water through. You can use a smaller pump. You save money on the pump. You also save money on electricity every day. Our product uses aromatic polyamide composite material. The size is 8040. It looks similar to a low energy membrane. But low pressure works well on a wider range of water types.

This product are best for water that does not have too much salt. Think of tap water, well water, and surface water. These waters usually have 200 to 1500 mg/l of salt. You do not need a lot of pressure to push water through. Using a high pressure membrane on this kind of water is a waste. It is like using a big hammer to hit a small nail. A low pressure ro membrane is just right. The pressure is enough to do the job. And you save money compared to using a higher pressure membrane.

Many customers mix these two up. Let me make it clear for you. Low energy focuses on saving electricity. Its design goal is the lowest power cost per ton of water. Low pressure focuses on low pressure. Its design goal is allowing you to use a cheaper pump and simpler pipes. In real use, low pressure also saves some electricity. But not as much as low energy. If your project is very large, pick low energy. The electricity savings will be big. If your project is small or medium, pick low pressure ro membrane. It gives you good cost savings on both the pump and the power. We help you pick based on your project size.
