Perhaps the most attractive aspect of golfing is the idea of spending several hours in a park-like setting strolling across lush fairways, putting greens and tees. For this reason, golf course managers dedicate a great deal of resources to the maintenance and health of special turf grasses.
RO treatment system keeps golf course grass healthy
Consumers who choose to use a residential point-of-use (POU) reverse osmosis (RO) system in their home need to feel secure that their system is producing high quality, reliable water for their family. Because most of us lack sophisticated equipment at home to make this determination, many homeowners rely on trusted brands to deliver the water quality they expect.
Quality tests and certifications ensure reliable filter performance
Previous articles in this series explained principles of how reverse osmosis (RO) systems work and the main factors and components that impact their performance. Once a point-of-use (POU) RO system is operating in the field, there are several troubleshooting tips that can prevent failures due to shortened lifetimes. These failures are usually caused by scaling, biofouling or particles. This article will cover techniques and tools that are used to troubleshoot these failures.

Avoid fouling to keep RO systems running smoothly
There are several factors that impact the performance of a residential point-of-use (POU) reverse osmosis (RO) system. The previous article in this series (“Factors that Impact RO Filter Performance,” March 2010) highlighted how changes in the feedwater quality can impact the quality of the permeate water. This article focuses on how changes in the components used in a residential POU RO system impact the permeate water.

Lord Fletcher’s, an iconic restaurant located along the shores of Lake Minnetonka in Minnesota, was established in 1968. Specializing in traditional dining and evening entertainment, it has become a favorite spot for both young and old. In summer months the bars and patio are lined with guests enjoying the pleasant atmosphere.

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.

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.
