  1. Physical Parameters Dispersion Dry residuals Suspended solids Color Smell Chemical Parameters Organic substances Non-organic substances Salts Fats Proteins Carbohydrates Dissolved gases Ions Biological Parameters Bacteria Viruses Protozoa IV. Wastewater Treatment TechnologiesTopic. IV. 1. Wastewater Quality; General ClassificationWastewater Quality Definition:Wastewater is heterogenic mixture, containing impurities with various chemical composition, origin and dispersion, defining its quality.Wastewater Quality Parameters Classification:I. According to the Impurities Nature

  2. II. According to the Impurities Dispersion Dissolved - d < 10-6mm Colloidal - d = 10-6 - 10-4mm Suspended - d > 10-4mm Fine - d = 10-4 - 10-2mm Coarse - d > 10-2mm III. According to the Impurities Chemical Content Organic Substances - 60 % Mineral substances - 40 % IV. According to Biological Impurities Nature Bacteria Saprophytes Pathogens Viruses V. According to the Suspended Solids Settling Ability by 2 h Norm - totally 65 g/d.ca Settling - 60 - 70 % Non-settling - 30 - 40 % Wastewater Quality; General Classification

  3. I. Mineral substances Chlorides - 9 g/d.ca Alkali substances Sulphates (toxic if > 200 mg/l) Phosphates Organic Mineral (orthophosphates) Norm - 4,4 /d.ca Nitrogen - 8 - 12 g/d.ca Organic (proteins, aminoacids) Mineral ( ) Heavy metals ions Radioactive elements Measure - Kurie (Ku) 1 Ku = MRAD, which realises 3,7  / s Wastewater Quality; General ClassificationDissolved and Colloidal Substances

  4. II. Organic substances Fats - 10 % Carbohydrates - 25 - 50 % Proteins - 40 - 60 % Carbamide Detergents, Herbicides, Pesticides Wastewater Quality; General ClassificationDissolved and Colloidal Substances
