in this survey, with the main objective of studying final effluent treat ability of pars paper industries, the quantitative and qualitative characteristics of the effluent were firstly determined, which showed a min. and max. rate of 1350 and 1800 m3/hr, with 1400 mg/l and 839.5 mg/l respectively for cod and tss, as the main contaminants. also cod and tss population equivalents were calculated ...

this study investigated the occurrence and removal of 12 antibiotics (ciprofloxacin, enrofloxacin, levofloxacin, norfloxacin, nalidixic acid, azithromycin, clarithromycin, roxithromycin, lincomycin, novobiocin, sulfamethoxazole, trimethoprim) at four sewage treatment plants (stps): two stps in kyoto, japan and two stps in beijing, china. the stps differed in design and operation conditions, uti...

The experiments were carried out in an electro coagulation reactor with aluminum as sacrificial electrodes. The influence of electrolysis time, current density, pH, NaCl concentration, rotational speed of the stirrer and electrode distance on reduction of color, COD and BOD were studied in detail. From the experimental results, 25mA/cm2 current density, pH of 7, 1 g/l NaCl, 100 rpm, 28 ◦C tempe...

Pulp and paper mill effluent is highly polluting and is a subject of great environmental concern. In the present research we studied the removal of chemical oxygen demand (COD) and colour from paper mill effluent, using the coagulation process. A batch coagulation study was conducted using various coagulants such as aluminium chloride (AlCl3), polyaluminium chloride (PAC) and copper sulphate (C...

growing the water consuming and shortage of available fresh water resources, make “effluent reuse” an unavoidable issue in industry for supplying a part of needs for required water. on the other hand, increment in the production of paper products from wood and recycling their consumed products which release pollutants to the environment has increased the environmental concerns. thus, in present...
