Pyrogenic organic matter production

On the other hand, pressure is applied in reverse osmosis to drive the solvent (water) out of the high-concentration side into the low-concentration side this facilitates de-watering insoluble species for their removal. This process produces high-quality water and concentrated refuse. It separates and removes dissolved solids, organics, pyrogens, colloidal matter, viruses, and bacteria from water in the particle range 10 4—10—2 pm. Reverse osmosis can remove up to 95%-99% of the total dissolved solids (TDS) and 99% of all bacteria. It is used for the ob-tention of drinking water from seawater and for the production of ultra pure water in various industries. 

Compressed air is one of the utilities that may have direct or incidental product contact and therefore requires qualification. The types of contaminants found in compressed air, not surprisingly, are the same as those found in the ambient environment. These may include micro-organisms (e.g., bacteria, molds, and viruses), moisture, particulate matter, and possibly pyrogens. Undesirable levels of hydrocarbons from compressor lubricants may be found if the compressor is not of the oil-free type.
