Giving customers value is what most retailers and wholesalers are doing during the economic slump. With rising costs for products and shipping, it is difficult to maintain sales and acquire profits. Cutting costs without cutting corners can be difficult as well. Sizing a water system and applying the correct treatment system can be a daunting task because salespeople must take into consideration that the customer wants the best possible water treatment at the lowest possible cost.
Providing the right solution at a good value while maintaining profit margins
There are several factors that affect the performance of reverse osmosis (RO) filters. Generally, these factors can be divided into two groups: feedwater characteristics and system configuration. This article focuses on feedwater characteristics, and the next article will focus on system configuration factors. Differing feedwater can change the flow and rejection of an RO filter. The main factors to consider are the temperature, pressure and salt concentration in the feedwater.
How feedwater characteristics affect RO filter performance
The Linis Water Station III is a POU purification cooler that offers 15,000-gal-rated microfiltration and a 250-gpd RO system with 3.5 gal of onboard storage. Features include push-button dispensing, in-tank UV guard, BioCote antimicrobial surface protection and a large dispensing area. A 3/8-in. hub port enables the station to feed RO water to additional stations as well as coffee makers and ice machines.
This is the first in a series of five articles providing an overview of how point-of-use (POU) reverse osmosis (RO) technology works in residential systems and the critical parameters to keep in mind to optimize its performance.
An introduction to RO and its applications
Green by Design RO systems reduce wastewater and operating costs. The R-1500 produces 1,500 gpd with only 375 gpd to the drain. The system has a compact frame, 16 in. wide by 16 in. deep and 30 in. in height, and is equipped with an SS membrane vessel, TDS monitor, blending and recirculation valves.

The H-Series RO system produces 700 to 1,500 gal per day in a compact footprint: 19 in. in height by 28 in. in width and 11 in. deep. The stainless steel systems are designed for restaurants, beverage kiosks and misting systems. Product water TDS can be adjusted for high purity or high recovery with recirculation and blending valves.
Titan H and J Series wall-mount RO systems have been engineered for capacities ranging from 250 to 4,000 gal per day. They are designed for overall high performance, higher recovery rates, minimal energy consumption and offer greater savings with lower maintenance and operation costs.
