R. O. Systems

Once that recommendation is made, you can have complete faith that your system will work at its peak potential over a long period of time. You can choose to buy a reverse osmosis system "off the rack" and take your chances or you can let us tailor make a system based upon your specific needs. 

WE RECOMMEND AN EXISTING WATER ANALYSIS OR HAVING YOUR WATER TESTED REPORTS TO DETERMINE WHICH IS THE BEST SYSTEM FOR YOUR WATER CHEMISTRY.

At VALUE ENGINEERING We pride ourselves on our workmanship and our attention to detail. To ensure our customers that our systems will perform to their utmost potential

Feed Inlet Solenoid Valve
Liquid filled Pressure Gauges
Includes: TDS Meter -Tester. The Only Way To Know If Your Reverse Osmosis RO Membrane Is Performing Correctly - Tests for TDS (Total Dissolved Solids). A Must For All RO System Owners. Compare Incoming Feed Water To Treated Water. TDS is the sum of the mineral salts in water and if too high can result in objectionable taste, cloudy ice, interference with the flavor of foods and beverages and scale left behind in pipes, machinery, glass, etc.

Reverse osmosis applications include:

Computer design programs predict membrane performance under expected conditions and generate pressure and flow values for system operation. After installation and start up of a reverse osmosis system, the operational values of pressure and flow must be noted. Significant deviation from these values indicates that system maintenance is required. RO system maintenance generally consists of prefilter cartridge changes, mixing and addition of chemicals, and periodic membrane cleaning. These processes are critical to membrane longevity and proper system operation.

Pretreatment processes such as filtration, ion exchange, antiscalant injection, and pH adjustment are utilized to assist in preventing membrane fouling. Properly pretreated feed water is delivered to the membranes by the pressure boosting pump. As pressure is increased more water passes through the membrane. The amount of water passing through the membrane is referred to as flux and is generally expressed in gallons per square foot of membrane per day (GFD). Every membrane has a maximum recommended flux. The higher the flux the more water is produced. Contaminant rejection by the membrane remains constant and therefore the more water that passes through the membrane the higher the quality of this permeate water. It would seem that it would be best to operate membranes at maximum flux because they would produce the most water and the highest quality water. However, as more water is produced more contaminants are left behind and the concentration of contaminants at the membrane surface increases. High quality system design utilizes conservative flux values for prolonged membrane life.

_{The system must be properly designed and maintained to avoid the precipitation of these concentrated contaminants on the membrane surface}.

As filtered water passes through the membrane it leaves the rejected contaminants behind, concentrating the solution at the membrane surface.

^{The basic components of the reverse osmosis system} are the membranes and the pump which drives liquid through the membranes. The balance of the system componentry is made up of piping and valving to route fluid through the system, monitoring apparatus, electronic control of the process, and raw fluid pretreatment.

^{Many factors effect the separation process} including: pressure, temperature, flow rate, percent of passage through membrane, amount of matter in raw liquid, and type of matter in raw liquid. All of these factors must be considered in the design of the reverse osmosis system.

Reverse osmosis is a separation process in which dissolved ions, heavy molecular weight compounds, and particulate matter are removed from a liquid. The process splits the liquid flow into a purified stream of liquid which has passed through the membrane (permeate) and a concentrated stream of liquid which has passed over the surface of the membrane.
