Adlay is a cereal that has been used as food, but its use still limited. consists of high starch content, native adlay low water absorption capacity and other functional properties. The characteristics can be improved; some them are modified into porous starch. This study aimed to define granules improve the physicochemical properties by synergic modification microwave heat treatment (MHT) ozon...

Abstract Iran's most important iron ore mine is located in the central region, and because of water shortage this area, need to reuse effluent from essential. On other hand, there are no suitable conditions for treating large volumes Iran. For reason, produced should be reduced returned consumption cycle by using appropriate technology. This study aimed investigate ozonation/lime effect on poly...

Background and purpose: Trihalomethanes and haloacetic acids are formed through chlorination of waters containing natural organic matters and pose potential health problems. So, it is necessary to remove humic acid as the most significant natural organic matter in water. The aim of this study was to evaluate the efficiency of catalytic ozonation in removal of humic acid in presence of local...

Background and Objectives: A conventional treatment to stabilize the excess activated sludge is the aerobic digestion process but due to long aeration time, it requires large equipments as well as high investment cost. Because of high oxidation potential of ozone, sludge ozonation enhances stabilization rate and reduces sludge treatment equipment size and cost. Therefore, in this study, the com...

Ozonation experiments were performed using unchlorinated tap water used for filling municipal swimming pools, actual pool water and pool water polluted by addition of fresh tap water and artificial body fluid to evaluate ozone kinetics and water quality effects on formation of volatile disinfection byproducts during subsequent chlorination. The ozone reaction was observed to behave according to...
