Slide2:

Activated Carbon Filters 01 Organic compounds 02 Free chlorine This makes the water suitable for discharge or use in certain manufacturing processes. This process called adsorption, which relies on massive surface area inside activated carbon particles. The surface area of just one pound of activated carbon can be more than 60 acres.

Ion Exchange Ion exchange is used in many applications: Nuclear facilities Industrial processes Medical and pharmaceutical operations Ion exchange controls the purity and pH of water by removing undesirable ions and replacing them with acceptable ones . The exchange takes place between ions bound to “active sites” on a man-made solid substance called ion exchange resin, and an aqueous solution, typically municipal water, but it is also used to treat process or even waste water. © 2017 WaterProfessionals ®

Multimedia Filtration Multi-media water filters utilize multiple layers of filtration media like: Anthracite Sand Garnet These media filters are often chosen for use in multimedia filters due to the distinct differences in their densities.   Various sized contaminants become trapped in the multiple layers. This allows for more efficient turbidity removal and longer run times between backwash cycles.   A simple sand filter eliminates particles down to 25-50 microns, however a multimedia filter can eliminate particles down to 10-25 microns. © 2017 WaterProfessionals ®

Reverse Osmosis The reverse osmosis process utilizes pressure on the "dirty side" (high mineral content side) of membranes, to overcome the natural osmotic pressure trying to flow the other way. Supplementary pressure is added to speed up the process, in order to force water across the semi-permeable membrane to the "clean side". During this RO process, 98% or more of the dissolved minerals are left behind on the "dirty side". © 2017 WaterProfessionals ®

Ultraviolet Ultraviolet disinfection processes use thin cylindrical bulbs that generate narrow band wavelength light around 254 nm.   The DNA and RNA of organisms subjected to UV light of sufficient dosage become damaged - destroying their ability to replicate - which prevents proliferation. © 2017 WaterProfessionals ®
