Industrial Water Softening Units are used to soften water by removing calcium, magnesium ions and the minerals that cause the water to be hard. These Water Softening Units are specific ion exchangers that are designed to eliminate positively charged ions. These Water Softening Units are able to remove up to five milligrams per litre [5 mg/L] of dissolved iron. Industrial Water Softening Units can operate on automatic, semi-automatic or manual mode of operation.
