Devoted to a Better Lab Water Experience

In order to produce pure water suitable for use in scientific applications, water must pass through a series of technologies which remove impurities. Various laboratory applications require the removal of different impurities and therefore a range of technologies are utilized.

PRE-TREATMENT

Filtration

Depth filters are commonly used as pre-treatment. Raw water passes through a series of winding fibers and carbon, which attract and trap impurities. This offers protection to the RO membrane and other purification technologies that follow. Membrane sub micron filters are traditionally used as the final step to remove bacteria and other particles which have not been dealt with by the preceding technologies.

TYPE 3 WATER

Reverse Osmosis (RO)

This is the most economical method of removing up to 99% of feed water contaminants. During natural osmosis, water flows from a less concentrated
solution through a semipermeable membrane to a more concentrated
solution until concentration and pressure on both sides of the membrane
are equal. In water purification, external pressure is applied to the more
concentrated side of the membrane to reverse the natural osmotic flow. This
forces the feed water through the semipermeable membrane. The impurities
are deposited on the membrane surface and flushed to drain.

TYPE 2 WATER

Deionization (DI)/Ion exchange

This process removes ions from water, usually RO water, with the use of synthetic resins. The ions are removed from the water through a series of chemical reactions. These reactions occur as the water passes through the ion exchange resin beads. Gradually, all unwanted ions are replaced by hydrogen and hydroxyl ions which combine to form pure water.

TYPE 1 WATER

Ultraviolet (UV) photo oxidation at 254nm and 185nm

Photochemical oxidation and ultraviolet light eliminate trace organics and inactivate microorganisms in feed water. The 254nm light reacts with bacterial DNA resulting in denaturation. The 185nm light breaks up long chain organics which can then be removed from the water by ion exchange.

Ultrafiltration (UF)

Ultrafiltration is used to remove pyrogens (bacterial endotoxins) and nucleases. This process is critical when producing water for use in tissue or cell culture and media preparation. Ultrafilters use size exclusion to remove particles and macromolecules. Ultrafilters are usually employed at the end of the system to ensure near total removal of macromolecular impurities like
pyrogens, nucleases and particulates.
