Description: ULP1812-75G circle composite membrane. For a variety of household water, hospital, laboratory pure water device and other small systems. Specifications: Condition: New Model: ULP1812-75 The membrane at 25 ℃ temperature , the water pressure was under 5.5 kg condition, 1 day (24 hours) produced 75 gallons water (US 1 gallon = 3.785 liters). Circle Formula: Ring-wound Material: Membrane is a composite material Main Color: Blue Size: Approx. 28.4 * 3.9cm / 11.18 * 1.54in Weight: Approx. 207g Package Includes: 1 x Reverse Osmosis Element Water Filter Membrane Element Note: 1. Please allow 1-2cm error due to manual measurement. Thanks for your understanding. 2. Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard. Features ???? HIGH QUALITY MATERIAL: The reverse osmosis membrane is a composite material, food-grade material is safe and non-toxic, does not contain BPA. harmless to the human body, you can rest assured that the use. Please note that new membranes need to be rinsed for 30 minutes. ???? WORKING PRINCIPLE: This reverse osmosis cartridge uses an ultra-hydrostatic pump to generate high pressure osmosis, which allows water molecules and ionic mineral elements to pass through a layer of reverse osmosis membrane and removes contaminants from the water. ???? REDUCES FILTH: Using a reverse osmosis element reduces fouling and reduces the frequency of cleaning. Removes contaminants as small as 0.0001 microns and removes more than 1,000 contaminants such as arsenic, lead, mercury, fluoride, hardness, cadmium, chlorine, and odours from source water. ???? YIELD: Reverse Osmosis water filters produce 75 gallons of water per day (24 hours) at 25°C and 5.5 kg of water pressure (1 gallon = 3.785 litres in the USA). Lasts up to 2 to 3 years. ???? VERSATILE: ULP Series membrane elements are suitable for use in most reverse osmosis water filtration systems. And they are well suited for desalination of surface water, groundwater, tap water and other water with salinities below about 2,000 ppm.
