Methods of sewage treatment pdf

The basis of sewage treatment in the vast majority of treatment plants is enhanced natural biological action and rarely, chemical treatment. By providing optimum conditions, raw sewage is broken down to non-toxic substances by the action of micro-organisms. The present invention discloses a method of sewage effluent treatment comprising oxidizing sewage effluent by reacting hydrogen peroxide with a catalyst selected from the group consisting of potassium iodide and potassium hydroxide, while in communication with the sewage effluent. If desired, the reaction may be initiated with metalloid kwatery-miedzyzdroje.com by: Coliform bacteria are used as an indicator of disease-causing organisms. Sewage also contains nutrients (such as ammonia and phosphorus), minerals, and metals. Ammonia can range from 12 to 50 mg/l and phosphorus can range from 6 to 20 mg/l in untreated sewage. .
