Water Concern: Well water contains a high volume of contaminants ranging from calcium to bacteria. The quality of water derived from a well often requires thorough treatment before utilized for its intended application. For drinking purposes, there are a set of requirements in place by the World Health Organization (WHO) that must be adhered to for the sake of public health. In addition, contaminants such as chlorine that may not be as harmful to consume still need to be reduced due to the impact on taste quality. Other issues like hardness and fluoride must be considered as well when providing water to the public.

This system included a prechlorination unit (CDS), a multi-media filter and carbon filter from our MF-400 Series, a water softener from our SF-500 Series, a commercial reverse osmosis system model #TW-4.5K-340 was selected from our RO-200 Series, and lastly a UV sterilizer from our UVC Series.

Applied Solution: A commercial RO system was recommended to this client for use of producing high quality drinking water. In order to meet the requirements set by the WHO, the system is comprised of a six-step purifying process. First, the feed goes through a prechlorination unit to decrease the potential for bio-fouling. Second, the multi-media filter reduces the turbidity or suspended solids present in the well water as a preparatory step for the RO system. Third, the water passes through a carbon filter to remove any chlorine residuals prior to contact with the membranes. Fourth step includes a water softener to reduce hardness in the water in order for the RO unit to efficiently remove all major contaminants. Next, the water is guided through the commercial RO system for further purification and fluoride reduction. This step consists of finely pored membranes that produce the highest quality water. Sixth step includes a UV sterilizer utilized for further disinfection.
