Due to the severe pollution taken place in Taihu Lake, the investigation of water source quality in Taihu Lake is urgent for the development of drinking water treatment processes. Water samples taken from two water source areas in Taihu Lake were analyzed. The results showed that ammonia, TN, TP and CODMn were the dominant contaminants. The concentrations of those contaminants all exceeded “surface...
Open-channels networks used for water distribution are subject to algal developments that can induce major disturbances such as clogging issues on hydraulic devices (pipes, weirs, filters,...). We already studied the use of flushes to manage these algae developments. The flush is carried out by increasing the hydraulic shear conditions using the hydraulic structures of the canal network. In response...
Water quality and temperature have important influences on energy efficiency of Lakes Water Source Heat Pump (LWSHP) systems. The characteristics of lake, especial spatial and temporal distribution features, must be obtained in order to take high quality water. By one year' s monitoring for quality and temperature of Caiyun lake in Chongqing, the results show that average monthly temperature was 26~30°C...
A new process of enhanced dissolved air floatation (DAF) by pulsed high voltage discharge was studied in this paper. With high voltage discharges, removal rate of some normal water quality indexes were better improved, such as UV254 and CODMn from 0.145 to 0.142 and from 6.2 mg/L to 5.8 mg/L. The turbidity of water after treated with pulsed high voltage discharges was larger than that without discharges...
