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. The total Nitrogen reduction process has
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. COD is closely related to BOD or
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
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. 8. BALANCE TANK: A tank placed before a BMS BLIVET installation when most of the SEWAGE flow comes over a few hours
Week 3 of our series explaining terms/jargon/terminology used in the area of sewage or wastewater treatment sees us concentrating on terms beginning with 'C-E'. The terms are; Clarifier, COD, Combined System, Denitrification, Dry Weather Flow, Effluent, Effluent Treatment Plant/System & Eutrophication. 14. CLARIFIER: See HUMUS TANK 15. COD: It is a test of the amount of oxygen required to oxidise
We are back with Week 4 of our series explaining terms/jargon/terminology used in the area of sewage or wastewater treatment. This week we review terminology beginning with 'C-E'. The terms are; Ferric Sulphate (FeSO4), Final Effluent, Final Settlement Tank, Foul Sewage, Humus Tank, Influent & Kjeldahl Nitrogen. 22. FERRIC SULPHATE (FeSO4): A chemical that is dosed into
Butler Manufacturing Services (BMS) Ltd. series explaining terms/jargon/terminology used in the area of sewage or wastewater treatment continues with terms from N-P. The terms are; Nitrate: (NO3), Nitrite (NO2),Nitrification, Nitrogen (Total Nitrogen), Package, Phosphorous (P/TP), Plug Flow, Population Equivalent (PE) & Primary Settlement Tank (PST). 29. NITRATE (NO3): A form of NITROGEN found in aged sewage or
BMS series explaining terms/jargon/terminology used in the area of sewage or wastewater treatment continues with terms from R-S. The terms are; Raw Sewage, Rotating Biological Contactor (RBC), Sand Filter, Saran Filter, Separate Settlement Tanks, Separate System, Septic Tank, Sewage, Sewage Treatment Plant/System. 38. RAW SEWAGE: See FOUL SEWAGE. 39. ROTATING BIOLOGICAL CONTACTOR (RBC): A type of SEWAGE treatment
The last in BMS series explaining terms/jargon/terminology used in the area of sewage or wastewater treatment finishes with terms from S-W; Sludge, STP, Surface Water, Suspended Solids, Tertiary Treatment, UV Disinfection, Wastewater, Wastewater Treatment Plant/System & Whole Life Cost. We will publish the whole list from A-Z next week. Links to Parts 1-6 are available at
