“…Wastewater treatment operations commonly use sequential combinations of treatment with a coagulant, then with a cationic flocculant of very high mass but low charge density (Ghosh et al 1985;Ahmad et al 2007Ahmad et al , 2008Wang et al 2011;Žarković et al 2011;Ariffin et al 2012;Simonič and Vnučec 2012). The idea is to employ a suitable amount of a relatively inexpensive coagulant to reduce the surface charge of the suspended matter.…”

“…With their very long chains, flocculants are able to overcome such barriers by adsorbing on two particles simultaneously. Such polyelectrolytes have become widely used in clarification of wastewater from P&P mills (Wang and Pan 1999;Wong et al 2006;Ahmad et al 2007Ahmad et al , 2008Žarković et al 2011;Ariffin et al 2012;Simonič and Vnučec 2012).Wastewater treatment operations commonly use sequential combinations of treatment with a coagulant, then with a cationic flocculant of very high mass but low charge density (Ghosh et al 1985;Ahmad et al 2007Ahmad et al , 2008Wang et al 2011;Žarković et al 2011;Ariffin et al 2012;Simonič and Vnučec 2012).

The pulp and paper (P&P) industry worldwide has achieved substantial progress in treating both process water and wastewater, thus limiting the discharge of pollutants to receiving waters. This review covers a variety of wastewater treatment methods, which provide P&P companies with costeffective ways to limit the release of biological or chemical oxygen demand, toxicity, solids, color, and other indicators of pollutant load. Conventional wastewater treatment systems, often comprising primary clarification followed by activated sludge processes, have been widely implemented in the P&P industry. Higher levels of pollutant removal can be achieved by supplementary treatments, which can include anaerobic biological stages, advanced oxidation processes, bioreactors, and membrane filtration technologies. Improvements in the performance of wastewater treatment operations often can be achieved by effective measurement technologies and by strategic addition of agents including coagulants, flocculants, filter aids, and optimized fungal or bacterial cultures. In addition, P&P mills can implement upstream process changes, including dissolved-air-flotation (DAF) systems, filtration save-alls, and kidney-like operations to purify process waters, thus reducing the load of pollutants and the volume of effluent being discharged to end-of-pipe wastewater treatment plants.

“…CP principle represents the continuous proactive environmental approach to reduce pollution at the source of production. In addition, the ability of clean production methods is in developing clean systems and creating social and economic benefits (Zarkovic et al, 2011;Giannetti et al, 2008 (Huang et al, 2005). Cleaner production has allowed industrial production to find a place in this vision by recasting negative impacts of polluting industrial processes and products into positive images of news technologies that are materials-conserving, energy-efficient, nonpolluting and low-waste, and that produce ecologically friendly products, like which are responsibly managed throughout their lifecycle (Geiser, 2001).…”

Abstract. In recent years, smart imaging and error detection to achieve optimum performance in water and sewage treatment plants using Artificial Neural Network (ANN) detection technique has had a very active research field and has been regarded as one of the modern methods of modeling. This study has focused on predicting the sludge produced by the oxylator unit of the water treatment plant using an artificial neural network with multilayer Perceptron method. The measured input data: water flow, pH, turbidity, temperature, free residual chlorine, conductivity, consumed lime, coagulant (ferric chloride), and magnum and the sludge produced by the oxylator were examined as output data of the model in two consecutive years 2014 and 2015. At the end, the results of neural network analysis were used to show the effect of each of the parameters in the production of sludge. According to the results, turbidity and pH are the most effective parameters in predicting the sludge produced by the oxylator unit of the water treatment plant. This study indicated that artificial neural network could achieve a 0.99 validity with a regression of 0.9881 and mean square error of 0.006 among the observed and predicted output variables of the model. In addition, artificial neural networks provide an effective tool to analyze the data to understand and simulate the nonlinear behavior of treatment plants.
