Objectives

To present the operations involved in the qualitative and quantitative characterization of liquid effluents and sludges and the meaning and importance of the more relevant physical, chemical and microbiological parameters.

Program

1. Main reasons for wastewater characterization
2.Inventory of wastewater production in industrial plants
3. Sampling methodology
4.Selection of parameters to measure.
5.Physical parameters: temperature, density, colour, turbidity, suspended and dissolved solids, settleable solids, odour.
6.Organics: BOD5,COD, KMnO4 oxidability, TOC, TOD, oil and grease, surfactants, VOCs, priority organic pollutant.
7.Inorganics: alkalinity/acidity, hardness, iron and manganese, organic nitrogen, ammoniacal nitrogen, nitrites, nitrates, phosphorous, sulphate, chloride, heavy metals, dissolved oxygen, ORP, sulphide, microbiological parameters.
8.Sludge characterization: SVI, SDI, oxygen uptake rate (SOUR).
9.Characterization of industrial wastewaters: textile, leather tanning and metal plating wastewaters.
10.Characterization of sewage and urban wastewaters.
11.Calculation of sewage and indusrial effluents flow rates.
12.Techniques for measuring flow rates.
13.Watewaters treatability: selection of alternatives and tests for evaluating physical, chemical and biological treatability.
