This paper presents an experimental application of PID control to study the electrocoagulation process of textile wastewater. The addition of NaCl solution would also lead to the decrease in power consumption because of the increase in conductivity. Conductivity in electrocoagulation process is difficult to control because of the complex nonlinear behaviour involved. Conductivity changes during...

The word "electrocoagulation" (EC) will be sometimes used with "electroflotation" (EF) and can be considered as the electrocoagulation/flotation (ECF) process. Through the process of electrolysis, coagulating agents such as metal hydroxides are produced. When aluminium electrodes are used, the aluminium dissolves at the anode and hydrogen gas is released at the cathode. The coagulating agent co...

Electrocoagulation of a plant extract and certain substances representative of selected classes of plant pigments, viz. chlorophyll, a carotenoid, a phenolic substance and a tannin, was performed in ethanol containing varying amounts of water (15-75%). The results showed that the extent and efficiency of coagulation of these substances tends to vary in a manner directly related to the water con...

Papillomavirus DNA has been reported recently in the vapor (smoke plume) derived from warts treated with carbon dioxide laser; this raises concerns for operator safety. We therefore have studied a group of human and bovine warts to define further the potential risk of wart therapy and to test whether a surgical mask could reduce exposure. Half of each wart was treated with carbon dioxide laser ...

This paper examines the use of chemical or electrocoagulation treatment process followed by ion-exchange process of the textile dye effluent. The dye effluent was treated using polymeric coagulant (cationic dye-fixing agent) or electrocoagulation (iron and aluminum electrode) process under various conditions such as various current densities and effect of pH. Efficiencies of COD reduction, colo...

Various techniques such as physical, chemical, biological, advanced oxidation and electrochemical are used for the treatment of industrial effluent. The commonly used conventional biological treatment processes are time consuming, need large operational area and are not effective for effluent containing toxic elements. Advanced oxidation techniques result in high treatment cost and are generall...

One of the new methods used to remove contaminants from effluent is electrocoagulation method, which sometimes combined with other increase removal efficiency contaminants. To simultaneously nickel, cyanide, zinc, and copper, method photo-electrocoagulation was along an oxidizing agent, namely hydrogen peroxide (Hp). In addition, effects factors affecting were studied, including pH, electrode a...

BACKGROUND Female sterilisation is the most popular contraceptive method worldwide. Several techniques are described in the literature, however only few of them are commonly used and properly evaluated. OBJECTIVES To compare the different tubal occlusion techniques in terms of major and minor morbidity, failure rates (pregnancies), technical failures and difficulties, and women's and surgeons...

Electrocoagulation is a method that can be used to remove pollutants and nutrients from liquid waste. This has been found for long time but exclusively recently developed wastewater treatment after lengthy process. colloidal materials, i.e., suspended solids, metals, other dissolved solids in wastewater. Several studies have shown electrocoagulation successfully operated various industrial wast...

Ischemic stroke is a devastating disease that represents the second leading cause of death worldwide [1]. As ischemic stroke in patients usually results from a thrombotic or embolic occlusion in a major cerebral artery, most often the middle cerebral artery (MCA), experimental focal cerebral ischemia models have been developed to mimic human stroke and serve as an indispensable tool in the stro...
