A simple flow-through system has been developed which makes use of wasted heat generated in traditional clay ovens (chullis) to pasteurize surface water. A hollow aluminium coil is built into the clay chulli, and water is passed through the coil during normal cooking events. By adjusting the flow rate, effluent temperature can be maintained at approximately 70 degrees C. Laboratory testing, alo...

In order to improve the treatment processes of drinking water plant (DWTP) located near Butoniga reservoir in Istria (Croatia), a prediction quality index (WQI) was done. Based on parameters such as temperature, pH, turbidity, KMnO4, NH4, Mn, Al and Fe, calculation WQI conducted, while for models, along with mentioned parameters, O2, TOC UV254 were additionally used. Four models built predict t...
