No need to strain your back and your budget to deal with hard water! Scaltrol water treatment effectively deals with lime (calcium) and other minerals that shorten the life of your dishwasher, water heater, washer, pressure washer and other expensive appliances at your home, farm or business. Scaltrol relies on an advanced, residential/small commercial version of the sequestering process that has been effectively used by municipal water authorities since the 1920"s. The Scaltrol unit will not only prevent additional lime and magnesium deposits from forming but will also assist in removing your existing deposits. Basically the minerals are held in suspension and allowed to just harmlessly pass through the water system.Imagine soft towels, no more scaled up showerheads, and appliances not bogged down by mineral deposits. Scaltrol provides this level of treatment without the high cost and potential health issues of conventional salt-based water softeners. Scaltrol is a US company and the product compound is NSF (National Sanitary Foundation) certified, giving you confidence they are safe for your home or business.Models are available to serve from single households to schools and dairies. This model, SC500, will treat up to 500,000 gallons and is ideal for dairies, nursing homes, apartments, motels, municipal building and other higher volume applications.
