Liquid filtration biological treatment

All non-invasive devices intended for modifying the biological or chemical composition of blood, other body liquids or other liquids intended for infusion into the body are in Class lib, unless the treatment consists of filtration, centrifugation or exchanges of gas, heat, in which case they are in Class lla.

Treatment of contaminated liquids such as water, leachate, filtrate, groimdwater, storm water, surface water and industrial process waste water can be accomplished by several of SBP s technologies. Certain waste streams can be concentrated by the hyperfiltration units the permeate is clean water and the "ctMicentrate" contains the reduced volume of the pollutants. These concentrated contaminants can often be bioremediated, thus minimizing the waste stream. Other liquids may be treated directly, either by biological processes, or in the case of volatiles, air stripping with biotreatment of the pollutants in a gas phase bioreactor, or "biofilter".
