“…In the third step, the solution is mixed again, but this time in a slow fashion, to encourage the formation of insoluble solid precipitates, the process known as "coagulation." The final step is the removal of the coagulated particles by way of filtration or decantation (Yılmaz et al, 2007).…”

Industrialization played an important role for scio-economy of the country. Generally, a lot of water is used and lot of wastewater generated from industries due their processes and washing purpose. A large number of chemicals are used for the production of potable water and in the treatment of wastewater effluents. In potable water treatment chemicals such as inorganic salts and polymeric organic coagulants are used for primary coagulation, as coagulant aids and for sludge dewatering; lime and soda ash allowed for pH correction and water stabilization; caustic soda is used for pH adjustment, powdered activated carbon (PAC) can remove taste and odour compounds and micro pollutants such as atrazine, bentonite aid's coagulation, and ammonium hydroxide is used in chloramination. The main object of review is focus on research work done as well as the basic concept behind treatment and application by the researcher on different industry's waste-water treatment. ©JASEM

“…It removes metals, colloidal solids and particles, petrochemical hydrocarbons and soluble inorganic pollutants from aqueous media (Yilmaz et al, 2007;Moussavi et al, 2011). The technique has been tested for treatment of wastewater containing variety of the pollutants including foodstuff, dyes, polymeric wastes, fluorine, chemical and mechanical polishing wastes, nitrate, phenolic wastes and refractory organic pollutants (Giwa et al, 2012;Chaturvedi, 2013).…”

Oily wastewater represents a dangerous threat when discharged to receiving bodies. This research investigates electrocoagulation as a simple, effective and economic technique for treatment of such wastewater. Bench scale reactors were used to evaluate the factors that may affect the treatment of a wastewater obtained from Kuwait Gulf Oil Company. Aluminum was used as a sacrificial anode. Electrodes were arranged at different configurations (horizontal, vertical and vertical anode with horizontal cathode) to select the optimal one. Other tested operation parameters include time of treatment, current density, the distance between the electrodes, anode tubes diameters and the electrolyte concentration of the emulsion. The treatment efficiency was evaluated by comparing the initial and final turbidity of the treated wastewater. Experimental results indicate that the efficiency of oil separation increased with the increase of the treatment time, current density, anode diameter and concentration of electrolyte. However, it decreased with the increase of distance between electrodes. The horizontal arrangement gave the best results. The data shows that oil separation increases slightly with increasing temperature. The optimum time and current density for oil separation was determined as 30 min and 30 mA cmG 2 , respectively. These parameters reduced the turbidity of the wastewater from 95-5 NTU.

“…Herhangi bir kimyasal madde ilavesi gerektirmeden ve oldukça makul bir elektrik enerjisi tüketimi ile (maksimum 0.8 kw saat/m 3 ) yüksek bor giderme verimi elde edilmesi laboratuar ölçekli modellerden tam ölçekli modellere geçiş için umut verici bulunmuştur. Sulardan bor giderimi amacıyla gerçekleştirilen bir başka çalışmada ise kimyasal koagülasyon yöntemi ile elektrokoagülasyon yöntemi karşılaştırılmıştır [41]. Elektrokoagülasyon yönteminde alüminyum elektrotların, kimyasal koagülasyon yönteminde ise koagülant olarak alüminyum klorürün kullanıldığı çalışmada, elektrokoagülasyon ile çok daha yüksek bor giderme verimi elde edilmiştir.…”
