Reverse Osmosis Distillation
Reverse Osmosis is known to be one of the most effective and economical ways to remove up to 99% of all contaminants. Reverse Osmosis membranes are designed to be much tighter than Nano or Ultrafiltration membranes. They typically will remove all particles, bacteria and organics greater than 200 Dalton molecular weight which includes pyrogens at almost 99% as well.
Lab Water Purification
In lab water purification process, hydraulic pressure is applied to counteract the osmotic pressure. Pure water is produced at a flow rate that is proportional to the water pressure. In most cases, reverse osmosis process is adequate for type 3 lab water requirements. Because reverse osmosis membranes are extremely restrictive, they generally have a lower production rate than that actually needed, therefore, containment tanks are typically necessary.
Reverse osmosis is an ionic exclusion process and only solvents are allowed to pass through the membranes. All ions and dissolved solids are rejected. Reverse osmosis membranes reject nearly all (greater than 99%) of strongly ionized polyvalent ions compared to 95% of weakly ionized monovalent ions such as sodium. As pressure increases so does the percentage of salt rejection.
When reverse osmosis systems are correctly engineered for feed water chemistry and the intended water use, these systems are the most efficient and economical ways to purify tap water.
In many cases, reverse osmosis is the preferred method of pretreatment for type one lab water polishing systems. For more information on Reverse Osmosis water purification, contact us at: firstname.lastname@example.org.
