This study was carried out to investigate the effect of treated wastewater on soil chemical and physical properties. Field experiment was conducted in Borkhar region in Isfahan province in central Iran with two water treatments of wastewater and groundwater under sprinkler and surface irrigation systems for three crops of sugar beet, corn and sunflower. Soil samples were collected to 120 cm depth to determine concentration of lead (Pb), manganese (Mn), iron (Fe), cadmium (Cd), nickel (Ni), cobalt (Co), copper (Cu) and zinc (Zn). Irrigation systems had no significant effect on extractable heavy metals in soil. The accumulation of Pb, Mn, Ni and Co in the soil increased significantly in the wastewater treatment as compared to the groundwater treatment. The accumulation of Pb, Mn, Ni, Co, Cu and Zn decreases with the soil depth. Treated wastewater showed no effect on the increase of Fe, Cd, Ni, Cu and Zn during growing season. The irrigation system had a significant effect on infiltration rate, bulk density and total porosity. Under sprinkler irrigation system the infiltration rate increased significantly

Raw (RW) and Waste Stabilization Ponds treated wastewater (TW) were used in comparison with groundwater (Control) for crop production under arid and saline conditions without any chemical fertilization. Four irrigation methods namely, surface, drip (with 2 systems “Bas Rhône” and “Rain bird”) and sprinkler irrigation were compared on each water type. The results of the 3-year-experimentation period were: a) TW applications instead of groundwater attenuated the detrimental effect of water salinity on the crop; b) Drip irrigation, “Bas Rhône” system, showed the highest irrigation performances and crop yields; c) the morphology and the way the crop was conducted were found to play an important role in determining its final bacteriological quality; d) TW irrigated crops and soils did not show any helminth eggs contaminations and e) Faecal coliforms were not isolated from the TW irrigated soil beyond the limit of 0.25 m.

Main Material

The industrial production of ethanol by fermentation using molasses as main material that generates large quantity of wastewater. This wastewater contains high levels of colour and chemical oxygen demand (COD), that may causes serious environmental pollution. Most available treatment processes in Vietnam rely on biological methods, which often fail to treat waste water up to discharge standard. As always, it was reported that quality of treated wastewater could not meet Vietnameses discharge standard. So, it is necessary to improve the treatment efficiency of whole technological process and therefore, supplemental physico-chemical treatment step before biodegradation stage should be the appropriate choice. This study was carried out to assess the effect of coagulation process on decolourization and COD removal in molasses-based ethanol production wastewater using inorganic coaglutant under laboratory conditions. The experimental results showed that the reductions of COD and colour with the utilization of Al2(SO4)3 at pH 9.5 were 83% and 70%, respectively. Mixture FeSO4 – Al2(SO4)3 at pH 8.5 reduced 82% of colour and 70% of COD. With the addition of Polyacrylamide (PAM), the reduction efficiencies of colour, COD and turbidity by FeSO4 – Al2(SO4)3 were 87%, 73.1% and 94.1% correspondingly. It was indicated that PAM significantly reduced the turbidity of wastewater, however it virtually did not increase the efficiencies of colour and COD reduction. Furthermore, the coagulation processes using PAM usually produces a mount of sludge which is hard to be deposited.

Islamic Psychology

This research aims to describe the application of Islamic Psychology in the practice of Muslim psychologists and the obstacles in its application. This study uses a qualitative approach for taking respondents using purposive sampling techniques. There are twenty respondents in this study. The method used in collecting data from this study is the interview and Focus Discussion Group. This study found that the understanding of Islamic Psychology was quite diverse, but in essence, an approach that used the Qur'an and Hadist was the primary reference source. Its application, including the psychological services, and the process of counseling and therapy were carried out by integrating psychology and Islam. The cases also handled varied, not limited to severe or mild cases. The challenges were related to the ability of the psychologists and the acceptance of the clients.
