1. Water Pollution and Waste Water Treatment (20)
Water Pollution:
 Classification of sources and effect of water pollutant on human being and ecology
 Sampling, measurement and standards of water quality, Determination of organic
matters: DO, BOD, COD, and TOC.
 Determination of inorganic substances: nitrogen, phosphorus, trace elements, alkalinity.
Physical characteristics: suspended solids, dissolved solids, colour and odour,
Bacteriological measurements.
Waste water Treatment:
 Primary treatment: Pre-treatment, settling tanks and their sizing.
 Secondary treatment: Micro-organisms growth kinetics, aerobic biological treatment,
activated sludge process, evaluation of bio-kinetic parameters, trickling filters, RBC and
sludge treatment and disposal.
 Tertiary treatment: Advanced methods for removal of nutrients, suspended and
dissolved solids, advanced biological systems,
1. Oxidation methods: Chemical Oxidation – Chlorine/Hypochlorite/Chlorine
Dioxide
2. Advanced Oxidation Processes – Catalytic Oxidation
Fenton’s Reagent (H2O2 + Ferrous Ion), Photo Catalysis (UV + TiO2), Supercritical
Water Oxidation
3. Recovery of materials from process effluents.
