The DI-160 DI system is a five-stage reverse osmosis de-ionization system. The incoming feed water is:  

First:  Passed though a 10” ¾” NPT pre-filter that is a modified carbon block and particulate filter to 50 microns. This extends the life of the down line filters and removes gross contaminants from the incoming feed water. It has a life of 1500 gallons and should be replaced often. The filter is a ¾” flow filter and is designed for high pass through flow and to maintain water pressure. It also reduces 95% of chlorine in the water.  

Second: Passed though a 0.5-micron sediment filter. This filter is required to remove excess turbidity [particulate mater that may cause the membrane to plug up].  

Third:  A 0.5 Carbon Block filter for removal of additional organics and chlorine that can damage the membrane.  

Fourth:  A high rejection thin film composite reverse osmosis membrane. It removes over 98% of most inorganic salts, all micro-organisms and almost all high molecular weight organics in the water.  

Fifth:  A mixed multi-layered mixed bed de-ionization cartridge. This cartridge removes almost all minerals and organics that may pass though the membrane, producing laboratory grade water with > 17 Meg Ohm / cm2 resistivity.  

The DI 160 DI system comes equipped with a water purity monitor which measures the electrical conductivity of water and indicates when the value is above or below an internally set level. In general the purer the water, the lower the electrical conductivity. This association is used to gauge the relative performance of the RO/DI system removing contaminants from the water. While this does not detect the presence of silica or organic contaminants, it can be used to imply the level of TDS [Total dissolved solids] contained as disassociated ionic species in the water. A greater concentration of TDS results in higher electrical conductivity for water. , a user can determine when the performance of the System has degraded to a point where replacement of the membrane and or de ionization cartridge is required.  

Each system also has a 3 way valve for bypassing the DI membrane filter when water of RO quality is required . An auto shut off float valve is built into the system so that as soon as any reservoir is filled the system will shut down.  

Console Systems with Sinks and Faucets, RO Systems, Larger Pumped DI Systems are available.
