Graver Technologies provides innovative melt blown and cartridge filters for prefiltration through Reverse Osmosis.
As a reliable and well-proven water treatment solution for municipal, industrial, food and beverage, and healthcare processes, Reverse Osmosis (RO) is a technology that effectively removes a large majority of contaminants from the incoming water. By using a high-pressure pump to increase the pressure on the “dirty” side of the RO membrane, water is forced across the semi-permeable RO membrane, leaving almost all of the particles and dissolved salts behind in the reject stream. The RO membranes must be maintained by regular cleaning cycles, to get at minimum two years of service, and likely four or more. Since membrane replacement costs can be very significant, prolonging the life of the membrane is critical and often directly related to its pretreatment. While 1- or 5-micron nominal melt-blown filters are often used in these processes, the economics often support the use of higher-performance filter cartridges. Better incoming fluid quality to the RO modules can significantly reduce the operational expense of the RO system (lower energy consumption), and increase the cycle time between cleanings, all resulting in reduced labor input and an improved lifespan of the modules.
