Description
The WECO Backwashing filter with KDF®-85 is a Point-Of-Entry (POE) hydrogen sulfide removal system for municipal and well water supplies. KDF®-85 consists of high purity copper-zinc granules that use redox (the exchange of electrons) to remove hydrogen sulfide, ferrous iron, heavy metals, and control microorganisms in potable water without the use of chemicals. WECO backwashing filters are available in a variety of sizes. Please consult with WECO Technical Support for assistance in selecting the proper size filter to meet your water purification requirements.
Hydrogen sulfide (H2S) is responsible for noxious “rotten egg” odors in bath water, showers and drinking water. The odor may be noticeable only when the water is initially turned on or when hot water is run. Heat forces the gas into the air which may cause the odor to be especially offensive in a shower. Hydrogen sulfide is corrosive to metals such as iron, steel, copper and brass. It can tarnish silverware and discolor copper and brass. Hydrogen sulfide creates yellow or black stains on kitchen and bathroom faucets. Coffee, tea and other beverages made with water containing hydrogen sulfide may be discolored. Prepare foods’ appearance and taste are affected by H2S in water.
Ferrous iron is invisible in water until it reacts with oxygen and precipitates as ferric iron particles. Iron can foul water softeners and other ion-exchange resin filtration systems. Iron will also reduce the efficiency of reverse osmosis filtration systems. Iron gives hair orange-tinted highlights and interferes with coloring products. Iron particles clog shower heads and faucet aerators. Iron is known to foul and damage water-using industrial and medical equipment. Copper can cause hair to have a greenish tint that causes hair coloring products to look too dark. Blue stains in bath tubs, sinks and toilets are caused by copper. KDF-85 has anti-microbial properties that help reduce bacteria growth in the filter system.
Controller features include:
Water enters the top of the tank through the control valve and passes downward through the media bed, which removes impurities. The backwashing filter will clean itself periodically by rinsing away impurities it has filtered from water. When the filter medium is saturated with contaminants, the control valve automatically starts the backwash process. The backwash procedure is an operation where water passes backward through the filter media at a fast flow rate. It enters the tank at the bottom through the riser tube, then flows upward through the filter medium, exiting at the control valve and sent to waste. The rapid, turbulent upward waterflow, in addition to flushing away particulate matter, loosens and resettles the media bed, preparing it for another filtration cycle. The treated and conditioned water enters the riser tube at the bottom of the mineral tank, passing upward and exiting the filter through the control valve.
The WECO backwashing filter is available in a variety of sizes. The filter can be operated stand-alone or in conjunction with other filtration processes. Please contact WECO Technical Support for expert assistance sizing and configuring your filtration system.
