About this items:
Enjoy Your Water with Confidence: Our Reverse Osmosis membrane is meticulously engineered to eliminate up to 99% of over 1,000 impurities from your water. This includes the removal of up to 98% of lead, along with chlorine, fluoride, arsenic, asbestos, calcium, sodium, and a host of other unwanted substances.
Top-notch Quality : Our Reverse Osmosis Membrane is crafted from premium food-grade materials, designed to offer exceptional capacity and density. This ensures that only pure water molecules pass through, leaving contaminants behind.
Energy Saving: Designed to operate efficiently at a low pressure of 70 psi, our membrane significantly reduces power consumption, thereby lowering your operating expenses.
Wide TDS Range: Our membrane thrives in saline conditions, capable of handling water with Total Dissolved Solids (TDS) up to 3000 ppm, all while maintaining a consistent rejection rate.
Stable Rejection Rate 97% : Enhanced membrane formulation guarantees a steady rejection rate across a broad range of TDS conditions, ensuring reliable performance.
Peace of Mind Customer Service : We are committed to providing exceptional support. Should you encounter any issues with our products, please contact us promptly. We are eager to assist and ensure your satisfaction.
Key applications:
Ideal for residential and household reverse osmosis systems, as well as water purification devices in hospitals and laboratories.
Perfect for municipal water purification.
Also serves the food and beverage industries.
Suited for farms, restaurants, retail establishments,
garment shops, building material shops, manufacturing plants, machinery repair shops, printing shops, construction works, energy and mining sectors, advertising companies, and water plants.
