The primary concept of controlling the risk of infection from drinking-water for human use (including applications like washing and showering) was founded on epidemiological studies and risk assessments based on highly infectious microbiological agents and a normal population. The growing number of immunosuppressed patients, however, makes it necessary to develop new concepts to protect these p...

Information on dynamics of water quality is essential in fish rearing. The use biofloc technology (BFT) improves production regions with low availability. This study was carried out to evaluate the locally available carbon sources control total ammonia nitrogen and other parameters aquaculture system. Completely randomized design three different (wheat flour, rice bran molasses) four treatments...

An overview is presented on the projects that are being carried out by Water Quality and Treatment Laboratory team of LNEC which use activated carbon based technologies for treating water or wastewater. Emphasis is given to the chemical enhancement of conventional wastewater treatment using “green” powdered activated carbon options, hybrid adsorption/ membrane processes or biologically active c...

Water resources for irrigation can be difficult to obtain specially in the arid regions. However, for high humidity areas such as places close to the sea, water can be condensed from the air. In this paper we build water condensation system based on thermoelectric cooler. The system consists of cooling elements, heat exchange unit and air circulation unit. A solar cell panel unit with a relevan...
