This week we are concentrating on explaining terms or jargon beginning with 'B' used in the area of sewage or wastewater treatment. The terms are; Balance Tank, Biofilm, Biozone, Blivet, BMS & BOD/Biochemical Oxygen Demand.
In many specialist areas of professional, scientific and commercial life a certain 'jargon' builds up, often serving to mystify and confuse the outsider. Sewage Treatment is no exception and over the course of eight weekly articles we will attempt to define and explain the most commonly used terms in sewage/wastewater treatment especially those used in relation to package sewage treatment from ‘A-Z’.
When discussing package sewage treatment one parameter that we neglected to cover is that of COD which means Chemical Oxygen Demand. It is a test of the amount of oxygen required to oxidise organic matter in a sewage sample by chemical oxidation with a powerful oxidising agent such Potassium Dichromate.
Hi, today we are going to discuss how to actually denitrify (the conversion of NO3 to Nitrogen (N) and Oxygen (O2) gas which is given off in the atmosphere) which is the second step in the process to lower Total Nitrogen in treated sewage effluent and is termed Denitrification.
Hi, we are back to discuss how to lower the total level of Nitrogen from inlet to outlet of a sewage treatment plant. Total Nitrogen is often abbreviated to TN or N. The reduction of TN is a two stage process involving the conversion of Ammonia (NH4) to Nitrates (NO3) termed Nitrification, followed by the conversion of NO3 to Nitrogen (N) and Oxygen (O2) gas which is given off in the atmosphere, termed Denitrification.
