The standard for laboratory-grade water
RiOs systems produce Type 3, laboratory-grade pure water at a constant flow rate. Systems are fed directly with potable tap water and combine complementary purification technologies in a compact system design that is easy to operate, reliable, and allows total control over the water produced at a low operating cost.
What is the purpose for the Acid & Base PH cleaners for my Elix/Rios system?
» Answer
The RO Membrane is used to reject a highest percentage of ions, particles, organic molecules and bacteria. Therefore, the RO Membrane surface has a potential to scale with minerals and this will change the performance and affect its ability to reject, causing the percent rejection to drop and increasing the permeate conductivity. The use of the Acid & Base PH cleaners help restore the performance of the RO Membrane.
What is the difference between the Progard 2 and Progard 1? And which one would be best for my Elix/Rios water system?
» Answer
The only difference between the Progard 1 and 2 is the Progard 1 is a shorter size filter and the Progard 2 is a longer size filter. Therefore, the Progard 2 is recommended because of the larger filter capacity, and is considered a better pretreatment by itself for protecting the RO Membrane if the feedwater has a fouling index of <12 and a total chlorine level of 3 ppm. The Progard 2 will work for a total of 30,000 liters.
What type of purity does the Rios Water Purification System produce?
» Answer
The Rios System produces Type III water quality, known as Reverse Osmosis water. Most standard applications that use Type III quality are: general and non-critical applications; feed to washing machines for final rinsing of glassware, heating baths, autoclaves, etc.
What type of purity does the Elix Water Purification System produce?
» Answer
The Elix System produces Type II analytical grade water quality, also known as distilled water quality. The standard applications which use Type II quality are: buffer preparation, pH solution preparation, microbiological media preparation, feed to clinical analyzers, washing machines, preparation of reagents for chemical analysis or synthesis, feed to Type 1 ultrapure water systems, etc.
Why does the percent rejection reading drop below the set point after changing the Progard filter?
» Answer
The Progard prevents mineral scaling from building up on the RO Membrane surface, and this is done with a sequestering agent (Polyphosphate). Therefore, when a new Progard is installed on the Elix/Rios, Polyphosphate is released into the water and changes the Feed Conductivity, which in turn will temporarily lower the RO percent rejection.
