Some of the main objectives of the water treatment process are: 1. To reduce the impurities to a certain level that does not cause harm to human health. 2. To reduce the objectionable colour, odour, turbidity and hardness. 3. To make water safe for drinking. 4.Water Treatment Processes - dva8m4udvj7p2.cloudfront.net,Water Treatment Processes Water Softeners Softeners are designed to remove the minerals, calcium and magnesium, that cause scale and scum from hard water. They are intended to treat the whole house supply, so they are installed close to the point where the water supply enters the premises.

Activated Sludge Treatment Process Concept and System Design
Kraus process The Kraus process is a variation of the step aeration process used to treat waste-water with low nitrogen levels. Digester supernatant is added as a nutrient source to a portion of the return sludge in a separate aeration tank designed to nitrify. The resulting mixed liquor is then added to the main plug-flow aeration system. 85 -95Lecture Notes | Water and Wastewater Treatment Engineering,,Chemical Treatment - Softening - Part 1 (PDF - 1.5 MB) 9: Chemical Treatment - Softening - Part 2 : 10: Chemical Treatment - Adsorption and Ion Exchange (PDF - 2.2 MB) Field Trip to City of Cambridge Water Treatment Plant: 11: Gas Transfer and Air Stripping : 12: Disinfection (PDF - 2.4 MB) 13: Wastewater Screening, Primary Treatment (PDF - 2.2,,,,,
