Types of Pressure On Reverse Osmosis

Do you know what is meant by reserve osmosis? This is a system that can enable people to convert improper water into healthy water or free from aesthetic contaminants. Reverse Osmosis system has been used to meet the needs of clean water in the housing up to the spacecraft. Find the best reverse osmosis system by visiting our website.

– Low-Pressure System (commonly used in housing)

The low-pressure Reverse Osmosis system is a pressurized less than 100 psig. Usually used in residential areas that use the shelter system as in the following scheme. The placement container tank on top (countertop) is usually not pressurized, but the type of undersink tank is usually pressurized which will increase as the contents of the tank increase. This pressurized system is capable of providing enough pressure to move water from the holding tank to the faucet. But unfortunately, it will also create counter-pressure against the membrane, which can decrease the efficiency of the system. Some units overcome this problem by using a non-pressurized tank with a pump to get purified water when needed.

Low-pressure units are usually able to produce 2-15 gallons per day, with a great efficiency of reject water of 2 – 4 gallons for each gallon of pure water produced. The purity of water produced can reach 95%. This type of system is very affordable. This type of unit requires maintenance in the form of replacement of pre and post filter (usually 1 to 4 times per year); and replacement of Reverse Osmosis membranes every 2 to 3 years, depending on usage.

– High-Pressure System (commonly used for commercial and industrial)

The high-pressure system usually operates at a pressure of 100 – 1000 psig, depending on the membrane used and the water to be treated. This system is typically used for industry and commercial where large volumes are required but still at high purity standards. Most commercial and industrial systems use many membranes arranged in parallel to produce the desired amount of water. Water that has been processed from the first stage then proceeded to an additional membrane module to obtain a higher purification rate. The wastewater generated may also be directed to the next membrane module to improve the efficiency of the system (see diagram below), though flushing is still required as the concentration increases to a fouling level. The High-Pressure system for the industry is able to produce 10 to thousands of gallons of water per day with an efficiency of 1 – 9 gallons of wastewater. Water purity can reach 95%. This system is larger and more complicated than the Low-Pressure system.
