Integra L water purification units use proven reverse osmosis technology, in conjunction with activated Carbon and particulate filtration as part of the first stage of purification. Water from the first stage is stored in an integral stainless steel tank providing a continuous feed to a ringmain. To maintain microbiological purity, the circulating water is continually purified using UV and membrane filtration technology. The systems are configured to run on both hard and soft feed water; Integra LH and LS respectively. As standard, all Integra systems are equipped with sophisticated integral data logging technology providing a historic traceability for key operating parameters.
