Testing Packages Aid in RO System Design

Publication Date:

When considering reverse osmosis (RO) for water treatment, there are several things that should be taken into account. One of the most important things to consider is the quality of the water to be treated. RO is widely used to remove harmful inorganic contaminants; however, due to the limitations and higher operating cost, pretreatment of the water may be necessary. For example, hardness minerals are common in groundwater, and at high levels, pretreating with a softener is often recommended.

Components

Environmental World Products focuses on component distribution, sourcing and new product development for commercial and industrial water treatment applications. Its product line includes RO system components, such as membrane housings, filter housings, bag housings, filter cartridges, couplings, control valves, flowmeters, solenoid valves, needle valves, controllers/monitors and pressure gauges.

Test Package

The Complete RO Screen was developed with input from membrane manufacturers and treatment professionals. This package tests for most factors that can reduce the life of an RO membrane. Due to the nature of RO produced water, the testing was designed to provide lower detection levels. This test package is also beneficial for other applications that require pure water. New and improved compact packaging will reduce shipping costs.

Particle Characteristic Advantages in Adsorption Technology

A wide range of research and development is being conducted to solve the challenges of providing clean water, with a significant emphasis on drinking water. The research focus has included advanced membrane technology; changing water chemistry to suit the remediation technology of choice; and media modification for increased selectivity, activity and capacity.

The purpose of this study is to focus on sorptive media modification for improved performance.

Reducing Costs With RO

Today, beverage production facilities make a wide range of products, including carbonated soft drinks, energy drinks, juices, teas and purified drinking water. The number one ingredient in all of these products is water. Naturally, the quality of the water, as well as the operation of the water treatment system, are key to the quality and profitability of the facility.

RO Systems Improve Flow Rates and Reduce Waste

Publication Date: 
April 24, 2012

Axeon CRO Reverse Osmosis Systems feature a sleek, ultra-compact design manufactured for residential applications and for feedwaters up to 1,000 total dissolved solids (TDS). The systems utilize a single-cartridge design, which allows for high-flow membrane performance. The large-diameter tubing of the CRO systems provides a 30% faster flow rate from the faucet. The unique flow path of these systems can reduce water waste by 50%, resulting in more water to the tank and less water down the drain.
