Improving removal efficiency of organic matters by adding phosphorus in drinking water biofiltration treatment.
OBJECTIVE To investigate phosphorus limitation and its effect on the removal efficiency of organic matters in drinking water biological treatment. METHODS Bacterial growth potential (BGP) method and a pair of parallel pilot-scale biofilters were used for the two objectives, respectively. RESULTS The addition of phosphorus could substantially increase the BGPs of the water samples and the ef...
متن کاملEffects of Assimilable Organic Carbon and Free Chlorine on Bacterial Growth in Drinking Water
Assimilable organic carbon (AOC) is one of the most important factors affecting the re-growth of microorganisms in drinking water. High AOC concentrations result in biological instability, but disinfection kills microbes to ensure the safety of drinking water. Free chlorine is an important oxidizing agent used during the disinfection process. Therefore, we explored the combined effects of AOC a...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
preparation of engineered nano adsorbent with organic matters removal capability for water treatment sand filters
introduction conventional water treatment consist of unit processes include coagulation, flocculation, clarification, filtration and disinfection that goal is removal of turbidity, color and certain bacterial species. in filtration process flocculated substances that have not removed in pervious stage are sediment. filter media is often silica sand that removal mechanism is complex and consists...
متن کاملStudies on Water Drinking
The daily drinking of three liters of water with meals, for a period of five days, by a man twenty-two years of age who was in a condition of nitrogen equilibrium through the ingestion of a uniform diet, was productive of the following findings : 1. An increase in body weight, aggregating two pounds in five days. 2. An increased excretion of urinary nitrogen, the excess nitrogen being mainly in...
