In this work, a synthetic textile effluent containing a reactive dye (C.I. Reactive Orange 4) was treated in an electrochemical cell with titanium covered by platinum oxide (Ti/PtOx) electrodes to remove color. The discolored effluent was mixed with other textile mill process effluents (scouring, bleaching, washing, etc.), according to the rate of each effluent in the mill, and was submitted to...

The manufacture of paper generates significant quantities of waste water; which can have deleterious effects on the receiving waters; therefore there is a need to find a treatment process which can minimize these effects considerably. The raw wastewater from paper and board mills can be potentially very polluting. This paper reveals the results of laboratory experiments using a sequential batch...

The treated and untreated effluent sample from Sir Shadi sugar mill Ltd. Shamli Distt Muzaffarnager of Western Utter Pradesh India during 2011-12 were collected and brought into laboratory for studying Physico-chemical parameters like Color, temperature, pH, DO, BOD, COD, TDS, TS, TSS, Chlorides, Sulphate and Oil & grease, heavy metals seed germination pattern of some important cereal crops. Un...

In the pulp and paper industry, the water use minimization is a constant target. One way to reduce water use is to recycle the effluent in a closed-cycle concept. In paper mills, the main source of liquid effluent is the so-called whitewater, which is the excess water, originated from pulp stock dewatering and other fibre contaminated water. This research studied the reuse of paper mill whitewa...

Toxicants affect reproduction often at concentrations well below lethal levels. Also, the acidification of fresh waters has been shown to cause extinction of teleost fish populations usually through a failure of recruitment from younger generations. Both field and laboratory studies have documented that the greatest susceptibility to low pH occurs in the early developmental stages (e.g. Lee et ...

Maximizing recovery and characterization of extractable proteins from secondary paper sludge is essential to explore the potential value from utilization of readily available waste products from pulp and paper mills. A multistep physicochemical recovery process was used, involving optimum alkaline solubilization of protein into an aqueous phase followed by augmented physical disruption of cell ...

Paper and pulp industrial waste waters are a major environmental concern. As the treatment of these effluents is a major problem, exploring novel and feasible biotechnological interventions is very important. Utilization of white rot fungi as a means of biological treatment seems to be a viable option. The study was undertaken to use immobilization technique and Phanerochaete chrysosporium, a c...

The present study investigated whether fluctuating asymmetry can serve as a useful biomarker of environmental stress in the eastern mosquitofish (Gambusia holbrooki). Fluctuating asymmetry was measured in sexually mature females sampled from two Florida, USA, coastal streams: The Fenholloway River, which is dominated by effluent from a paper mill, and Spring Creek, a tributary to the Fenhollowa...
