Saline wastewater treatment by Electrochemical Method
Water Research, 1998Co-Authors: Sheng H. Lin, Ching T. Shyu, Mei C. SunAbstract:Abstract Treatment of saline wastewaters by Electrochemical Method is investigated in this paper. Experiments were conducted to examine the effects of the operating conditions, such as the pH, initial phenol concentration, salinity, current density, temperature and addition of small amounts of H2O2 on the COD removal efficiency. Possible optimum ranges for these operating variables are experimentally determined. The Electrochemical Method is found to be quite effective for dealing with the saline wastewaters with salinity of up to 3.5 w/w%. Two kinetic models were also employed to represent the Electrochemical treatment process. The experimental data allow determination of the kinetic parameters by the least squares curve fitting principle. The correlation of these two kinetic models to the experimental data is compared.

treatment of textile wastewater by chemical Methods for reuse
Water Research, 1997Co-Authors: Sheng H. Lin, M. L. ChenAbstract:Treatment of wastewater effluent from the secondary wastewater treatment plant of a dyeing and finishing mill is investigated for possible reuse. The treatment system employed in the present study consists of an Electrochemical Method, chemical coagulation and ion exchange. The Electrochemical Method and chemical coagulation are intended primarily to remove color, turbidity (NTU) and COD concentration of the wastewater effluent while ion exchange is employed to further lower the COD concentration and reduce Fe ion concentration, conductivity and total hardness of the wastewater. To enhance the efficiency of Electrochemical Method, addition of a small amount of hydrogen peroxide is found to be highly beneficial. Experimental results throughout the present study have indicated that the combined chemical treatment Methods are very effective and are capable of elevating the water quality of the treated waste effluent to the reuse standard of the textile industry.

Treatment of textile wastewater by Electrochemical Method
Water Research, 1994Co-Authors: Sheng H. Lin, Chi F. PengAbstract:Abstract Treatment of textile wastewaters from several dyeing and finishing mills by an Electrochemical Method is investigated. The batch experimental results are assessed in terms of color (turbidity) and COD reductions. Several operating variables, such as the wastewater conductivity, pH, power requirement and amount of polyelectrolyte added, are explored to ascertain their respective effects on the treatment efficiency. Optimum operating ranges for each of these operating variables are experimentally determined. The Electrochemical Method is found to be quite effective and is highly competitive as an alternative chemical Method for treating textile wastewater. A continuous experimental apparatus is designed and test runs are performed using the operating conditions obtained in the batch experiments. The preliminary data show similar satisfactory results to those of the batch runs.

Testing an Electrochemical Method for treatment of textile dye wastewater
Waste Management, 2000Co-Authors: A G Vlyssides, M Loizidoy, Danai Papaioannou, P K Karlis, Antonis A ZorpasAbstract:Wastewater from total dyeing and finishing stages (TDFW) and wastewater only from dyeing stage (DW) from a Textile cellulosic reactive azo dyeing process were treated separately by an Electrochemical Method using Ti/Pt as anode and Stainless Steel 304 as cathode. In this technique, sodium chloride was used as an electrolyte and the mixture was passed through an electrolytic cell. Due to the strong oxidizing potential of the chemicals produced (chlorine, oxygen, hydroxyl radicals and other oxidants) the COD, BOD of the wastewaters were substantially decreased using this Electrochemical technique. A number of experiments were run in a batch 5 litre apparatus and the results of the Electrochemical treatment on the two kinds of wastewaters are reported here. The results indicate that the Electrochemical Method used is feasible for treatment of textile dyeing wastewaters.

Textile Wastewater Treatment by Enhanced Electrochemical Method and Ion Exchange
Environmental Technology, 1997Co-Authors: S. H. Lin, M. L. ChenAbstract:Electrochemical Method is employed to treat the effluent from the secondary wastewater treatment plant of a large dyeing and finishing mill. The overall effectiveness of electro-chemical Method in elevating the quality of treated wastewater was found to be considerably enhanced with an addition of small amount of hydrogen peroxide (H2O2). Experimental runs were conducted to examine the effects of operating variables, particularly the amount of hydrogen peroxide and the Electrochemical treatment time, on the process performances and to determine the optimum operating ranges of those variables. By incorporating ion exchange with the Electrochemical Method, the quality of wastewater after the combined treatment was observed to exceed the reuse standard for the textile industries and the treated wastewater can be considered for reuse.
