Pharmaceuticals and Personal Care Products Reduction/Removal
Numerous pharmaceutical compounds have been shown to simply pass through conventional sewage treatment plants that were not designed to handle them and contaminate the aquatic environment. The ERT operating methodology of using sequential reduction and oxidation, acidification and alkalinization by varying the pH in treated waste streams removes many of those substances. Removal is accomplished through a combination of oxidation/reduction, and selective precipitation/filtration methods. The advantage of the ERT process is that it is flexible and adjustable to handle almost any targeted substances for removal. ERT makes use of a number of differing chemical methods that include: Sorption onto suspended solids, acid solids suspension, lime flocculation, acid hydrolysis, chemical precipitation, basic hydrolysis, chemical reduction and photodegredation. The ERT chemical method can be supplemented with other chemicals, such as ozone or ferric chloride, to deal with stubborn PPCPs depending on the specific circumstance. ERT has the technical expertise to work with clients and design custom solutions to meet their specific requirements.
