Wastewater from the food industry that contains a high organic load, such as wastewater tofu manufacturing process, requires an appropriate and efficient treatment system to reduce pollutants before being discharged into water bodies. The most suitable for loads is anaerobic system. process of suspended media, attached or combination thereof hybrid. This study uses Hybrid Upflow Anaerobic Sludg...

The presence of arsenic in water for human consumption is concern, especially developing countries, and the design simple economic treatments removal imperative. In this paper, three low-cost technologies were evaluated As(V) or As(III) (5 mg L?1) removal: (1) zerovalent iron (Fe(0)), as powdered (?Fe(0)) wool (wFe(0)); (2) coagulation-flocculation with Al2(SO4)3 FeCl3; (3) adsorption on a natu...

heavily polluted wastewater from sanitary landfill presents the leachate characteristics that need special treatment and disposal. concentration of chemical oxygen demand (cod), ammonia nitrogen (nh3-n), heavy metal and other pollutant content are often larger than standard requirement after applying biological/physico-chemical treatment.thus, the combination of coagulationflocculation and chem...
