Don’t spend more complicated and Expensive chemical to remove insoluble or inorganic chemical in Biological treatment process.

Why?, first the biological treatment theory used for

a) The destruction and conversion of organic chemical and biological pollutants.

b ) Inorganic chemicals cannot be destroyed by biological treatment, but they can potentially be converted in valence or oxidative state to compounds which [....]

Factors affecting Dissolved Oxygen concentration in water

what are the Factors affecting dissolved oxygen concentration in water Dissolved oxygen (DO) and water temperature are most commonly in situ monitored parameters for surface waters (rivers, streams, lakes, reservoirs, wetlands, ocean, etc.). Dissolved oxygen concentration in milligrams per liter (mg/L) is a measurement of the amount of oxygen dissolved in water. It can be determined with a DO meter [....]

Water Treatment using Silver

Silver has been suggested by some for water treatment.Its use is currently out of favor due to the EPA’s establishment of a 50 ppb MCL (Maximum Contaminate Level) limit on silver in drinking water.This limit is set to avoid argyrosis, a cosmetic blue/gray staining of the skin, eyes,
and mucous membranes.

As the disease requires a net accumulation of [....]
