What is Chlorine?

Chlorine is a primary disinfection treatment solution used by municipal water companies to deactivate and reduce bacteria in water. While helpful for killing bacteria, chlorine has also been know to cause unpleasant tastes and odors in drinking water. More severe results include the capability to affect respiratory, digestive, and circulatory symptoms under extensive exposure. Some people may experience dry and irritated skin and eyes after exposure to high concentrations of chlorinated water. Carbon media present in our Tier1 backwash system is a fantastic filtering media for reducing the presence of chlorine and its noticeable tastes and odors. Ensure you are getting the best tasting and filtered water available throughout your home with Tier1.

How Backwashing Filters Work

Backwashing is a process which reverses the flow of water to rinse and resettle the media of the tank to prevent channeling, retain the effectiveness of the media, and remove trapped contaminants. To begin the backwash process, water flow is reversed and sent down the riser tube which normally carries the filtered water out of the tank. The water entering the media tank actually lifts the media bed, swirling it and lifting contaminants trapped in the media upward, this water is then funneled out the drain line. This process of cleansing the filter media usually lasts for around 10 minutes. Following the backwash phase there is a rinse cycle which replicates the normal flow of water through the media, this rinses the media again and allows it to settle into its serviceable position. With the media resettled and cleansed, water filtration may resume.

"Channeling" Inefficiencies

Channeling is a process caused by a liquids natural tendency to follow the path of least resistance. Over time water will find a path it can flow the fastest through and will carve a path or channel following its flow. This process causes a lowered system effectiveness because water will begin to flow around the filter media instead of flowing through it as intended. To fight this process and remove suspended contaminants a backwash and rinse cycle will mix up the media and then resettle it, counteracting the channeling process and providing maximum contact between the water and filtering media.
