Case Study #1 United Filters Submicron Three-Stage System for Cost Effective Water Conditioning and Contaminant Reduction Effective Use of the Point-of-Entry Water Filtration System with Siliphos® Scale Inhibitor as a replacement treatment for areas where water softeners are banned. Distributor's customer lives in Santa Clarita, CA, a geographic area where water softeners have been banned for several years. They were still in possession of their softener, and were informed it had to be removed. The hardness in this area of Los Angeles County is approximately 25-30 grains, and most residents need some kind of water conditioning to protect their pipes, water appliances, laundry, etc. Two different systems were proposed to them: one three-stage system using NAC (nucleic-assisted crystallization) to break down minerals into harmless nano particles and the second system, United Filters’ Trident Three-Stage Water Filtration System, specially configured with the German-manufactured Siliphos® Scale Inhibitor. The Trident three-stage point-of-entry system was chosen to include the following:
Stage one – fast flow ULTRA-D submicron filter for reduction of dirt, sand, sediment, virus, bacteria, cysts, lead, other heavy metals, VOCs.
Stage two – ULTRA-D submicron filter with PAC (powdered activated carbon) and bacteriostatic silver (Agion) for reduction of chlorine, chloramines, virus, bacteria, cysts, lead, other heavy metals, VOCs, trace pharmaceuticals.
Stage three – Carbon wrap filter with Siliphos Hexapolyphosphate Scale Inhibitor down the center for reduction of chlorine, scale (calcium and magnesium).
After three months of usage, the customer reports the following:
Their water has a very pleasant flavor, thus, the filtration has been successful in reducing or removing many of the contaminants in their water. They have been able to eliminate bottled water, and use their filtered water for traveling, as well. They travel in their RV frequently and bring their filtered water in large containers to use for drinking instead of buying bottled water.
Water spots (dried from scale in water) are significantly reduced on glassware and shower enclosures, and any spots left are easily wiped off. Normally when scale dries, it is impossible to wipe off.
There is no noticeable buildup of scale in the dishwasher or other water appliances.
Summary: The Trident Three-Stage Water Filtration System is a cost effective cartridge-style alternative to other higher-priced systems that can treat very hard water while removing or reducing many contaminants from potable water.
Case Study #2 United Filters Stainless Steel Vessels and NO-Scale Filters for Commercial Tankless Water Heater Scale Control A distributor provided a cost effective, alternative treatment for boiler and tankless water heater limescale protection utilizing the United Filters stainless steel vessels, polyester pleated sediment filters and Siliphos Scale Inhibitor media. Water softeners have always been specified for this type of water treatment to protect heat exchangers against corrosion from limescale (calcium and magnesium minerals intrusion). Siliphos scale inhibitor has been used since the early 2000s as a more cost effective option with much less maintenance and friendlier to the environment. Commercial multi-tankless water heaters instead of water softeners are now being specified for large-scale apartment buildings, and require a more finite treatment for optimum operating capabilities. Building #1: 29-unit apartment building with five commercial condensing tankless water heaters in parallel feeding the hot water with a solar water heating system, also susceptible to scale corrosion. One five-round stainless vessel system with two-inch in and out ports, equipped with five 2.5-inch x 20-inch polyester pleated sediment filters and Siliphos Scale Inhibitor for approximately 50GPM flow rate was installed in the garage at the point-of-entry to the solar water heating system. After one year, filters have been replaced and effectively protected the tankless water heaters and solar water heating system against corrosion from limescale without compromising flow rate. Building #2: 78-unit apartment building with 14 commercial condensing tankless water heaters located at two areas on the roof. Two seven-round round stainless vessel systems with two-inch in and out ports, equipped with seven 2.5-inch x 20-inch polyester pleated sediment filters and Siliphos Scale Inhibitor for approximately 70GPM flow rate for each were installed on the roof to accommodate each seven-tankless heater rack system.
After one year, filters have been replaced and effectively protected the tankless water heaters against corrosion from limescale without compromising flow rate.
