A significant nutrient load can be generated internally by publicly owned treatment works (POTWs). These nutrients can be found in the reject water, also known as side streams, of many municipal wastewater and sewage sludge treatment processes. These side streams include the reject stream from membranes, supernatant liquid from sludge digesters, and the centrate/filtrate return stream from sewa...

The aim of our present study was to examine the regulation of xenobiotic- and antioxidant enzymes by phytogenic feed additives in the intestine and the liver of broilers. A total of 240 male Ross-308 broiler chickens (1 d old) were fed a commercial starter diet for 2 weeks. On day 15, the birds were assigned to six treatment groups of forty birds each. The control (Con) group was fed a diet wit...

Application of Granular Activated Carbon (GAC) in adsorption process has been studied for the advanced treatment of municipal and industrial wastewater. Because of entering poisonous compounds such as furfural, phenol and sulfides into the oily wastewater of Tehran refinery, biological aeration basins of wastewater treatment unit may not have the desired performance of COD reductio...

T he City of Clearwater (City) owns and operates the reverse osmosis (RO) water treatment plant No. 1 (plant) that was originally constructed in 2003. Similar to many brackish water RO facilities, the City blends pretreated raw water with RO permeate to maximize production while minimizing operational costs. In the case of this plant, the City blends 1 mil gal per day (mgd) of pretreated blend ...

objective: the aim of this study was to investigate the effect of pre-treatment with curcumin on metabolic changes induced by two different pathophysiological mechanisms in rats (fructose diet and streptozotocin (stz)-induced diabetes mellitus). materials and methods: five groups with 10 rats per group were investigated: control group (healthy rats), fructose diet groups without any pre-treatme...

The utilization of construction and demolition debris in industrial wastewater treatment by sorption Co2+ Ni2+ ions was investigated. Selected waste composites are cost-effective locally available, still their characteristics application not sufficiently samples concrete, facade, ceramic materials, asphalt were characterized terms mineral surface composition, radioactivity, stability at differe...

The application of membrane technology in water and wastewater treatment is increasing due to stringent water quality standards. Nanofiltration (NF) is one of the widely used membrane processes for water and wastewater treatment in addition to other applications such as desalination. NF has replaced reverse osmosis (RO) membranes in many applications due to lower energy consumption and higher f...
