Do treatment plants effectively remove drugs hormones from .

Wastewater reclamation plants – treatment plants that use additional processes to purify sewage – are already in operation. They produce water to irrigate crops highway landscaping golf courses and parks as well as to be reintroduced into the ground for groundwater recharge which ultimately could end up in drinking-water supplies.

Water Management in Refining Processes

Caustic treating is a refining process that uses an aqueous solution of NaOH to absorb acid gas compounds like H2S CO2 and mercaptans found in natural gas or liquid hydrocarbon streams. Crude oil fractions that exit from the vapor stream in a distillation tower contain sulfur- based compounds which are odiferous and corrosive.

Sewage treatment - Wikipedia

Sewage treatment is the process of removing contaminants from domestic and municipal wastewater containing mainly household sewage plus some industrial wastewater.Physical chemical and biological processes are used to remove contaminants and produce treated wastewater (or treated effluent) that is safe enough for release into the environment.
