A lab-scale electrocoagulation batch reactor was used to remove acid red 18 as an azo dye by use of aluminum electrodes. The effects of different parameters including initial pH, current density, reaction time, initial dye concentration, distances between electrodes, and type of the electrolyte solution on the efficiency of EC process were investigated. The influence of the current densities on consumed anode and produced sludge was also studied. Optimum conditions were obtained at pH 4. Removal percentage of the dye was significantly increased with increasing current density until reaching to critical point of 26 mA/cm 2 . Anode mass reduction was increased from 202 mg at current densities of 26 mA/cm 2 to 331 mg at 42 mA/cm 2 . Moreover, mass of produced sludge was increased from 605.85 to 1,060 mg with a net mass of 400-mg sludge production. The shorter distances between electrodes resulted in higher decolorization. Type of the electrolyte solution was an important parameter affecting the amount of the consumed electrolyte or energy required for decolorization.

Since the realization in the 1930s that elevated fluoride concentrations in drinking water can have detrimental effects on human health, new methods have been progressively developed in order to reduce fluoride to acceptable levels. In the developing world the necessity for filtration media that are both low-cost and sourced from locally available materials has resulted in the widespread use of bone char. Since the early 1990s metallic iron (Fe 0 ) has received widespread use as both an adsorbent and a reducing agent for the removal of a wide range of contaminant species from water. The ion-selectivity of Fe 0 is dictated by the positively charged surface of iron (hydr)oxides at circumneutral pH. This suggests that Fe 0 could potentially be applied as suitable filter media for the negatively charged fluoride ion. This communication seeks to demonstrate from a theoretical basis and using empirical data from the literature the suitability of Fe 0 filters for fluoride removal. The work concludes that Fe 0 -bearing materials, such as steel wool, hold good promise as low-cost, readily available and highly effective decentralized fluoride treatment materials.

“…Therefore, the remediation of water contaminated by these chemicals is necessary both to protect the environment and for future reuse [8][9][10][11][12]. Therefore, several biological, physical and chemical methods are used for the treatment of industrial effluents with different efficeincies [13][14][15].…”
