“…4). This technique can be used for other categories of pollutants such as detergents [33], pesticides [34], oils [35] and drugs [36]. The effectiveness of the treatment method varies considerably with several factors such as the concentration of the pollutant current intensity and pH [37], type of pollutant [38], and wastewater flow [39].…”

Pollution with contaminants from effluents of industrial units constitutes a danger to health and environment. This is the case of chromium (Cr) and formaldehyde [CH 2 O (H−CHO)] contained in leather tannery effluents, identified and characterized by ICP-OES (Inductively coupled plasma -optical emission spectrometry) and HPLC (High Performance Liquid Chromatography). The levels recorded for these two contaminants in wastewater constitute an environmental risk of average degree. The treatment of this wastewater by electrocoagulation completely eliminates chromium and reduces organic pollution by 65%. We applied an electric current (I) of variable intensity (1 to 2.5 Ampere). The best results were obtained with the highest current intensity.

“…Hospital effluents contain a variety of contaminants that its discharge to the environment can contaminate soil and water resources (8)(9)(10). These pollutants also are serious threats to the environment and important agent in spreading infectious diseases (11)(12)(13)(14)(15)(16). Hospital wastewater is one of the domestic wastewaters that contain pathogens, chemicals, pharmaceuticals and disinfectants (17,18).…”

Background & Aims of the Study:The most important compounds in hospital wastewater are antibiotics, disinfectants, anesthetics, radioactive elements, static cytotoxic agents, other chemicals and hazardous materials that caused to be different domestic sewage. The purpose of this study was the evaluation of performance of extended aeration biological system in pollutants removal from Razi Hospital wastewater treatment plant (WTP), Ahvaz city of Iran. Materials and Methods: The hospital wastewater disposal and treatment in Razi hospital have been studied in this cross-sectional research. Total of 12 samples from effluents of wastewater treatment plants were collected and tested for pH, Biological Oxygen Demand (BOD 5 ), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS) and Total Coliform (TC). EPA standard method was used for conducted trials. Finally, the relationship between results at different months and stations was done, using SPSS18 and descriptive statistics. Results: Results shown that parameters average in effluent was pH=7.46 ،BOD= 48.58 mg/l, COD=99.25 mg/l, TSS=54 mg/l, NH 3 =5.65mg/l, Turbidity=29.57 NTU. Also total coliform and fecal coliform of effluent were 46.19 MPN/100 ml and 36.65 MPN/100 ml, respectively. According to results, the percentage of BOD, COD, TSS and TC removal in WTP were 85.21, 82.46, 86 and 90.15. Conclusion:Based on these findings, Razi hospital effluent wastewater treatment plant was mitted at Iran environmental standards for discharge to recipient wasters. Based on the result of our study, Extended Aeration Biological System is a comparatively suitable process for BOD, COD, TSS and TC removal from hospital wastewater.

The objective of the present investigation was to construct an electrocoagulation cell in a batch system and to evaluate its capacity to remove the anionic surfactant of the linear alkylbenzene sulfonate (LAS), which is present in gray water determining the effect of the type of electrodes (Al or Fe), distance between electrodes (1, 1.5 and 2 cm) and voltages (10, 15 and 20 V). The experimental tests were carried out for 20 min. The dimensions of the short wave electrolysis cell built in glass were 26 cm long, 7 cm wide and 12 cm high, with 10 electrodes of 12x6 cm supported by a PVC structure. The concentration of LAS in the solution was determined by employing UV-Vis spectrometry applying the Methylene Blue Active Substances (MBAS) method. A higher removal of 65.55% was obtained when aluminum electrodes were used, and 69.11% with iron electrodes a separation of 1.5 cm and a voltage of 20 V, presenting less change in pH, conductivity, and energy consumption when using the Al3 electrode. When evaluating the effect of time at the best experimental configuration (Al, 1.5 cm, 20 V) it was established that the removal efficiency increased to 75.13% in 60 min. Electrocoagulation with aluminum electrodes is presented as an efficient alternative for the removal of LAS in solution.
