valves will be needed to make it easy to maintain
Carbon is “activated” by adding a positive charge UV water sterilizers, which enhances the adsorption and reduction of contaminants which have a negative charge. The three forms of activated carbon used in water filtration systems are granulated activated carbon (GAC), activated carbon block, and catalytic carbon. Activated carbon removes impurities, chemicals and contaminants from water through adsorption and a process called catalytic reduction.
