1. Evaluation of Modern Irrigation Techniques with Brackish Water
Sammanfattning : Modern irrigation techniques are becoming increasingly important in water-scarce countries especially in arid and semiarid regions. Higher crop production and better water use efficiency are usually achieved by drip irrigation as compared to other irrigation methods. LÄS MER
2. Batch Sorption Studies of Aqueous Cadmium and Lead from Contaminated Water onto Selected Biosorbents
Sammanfattning : Groundwater, wastewater, surface runoff and surface water samples from Lake Victoria basin, Uganda was assessed for trace metals contamination. Untreated, base-treated and peroxide-treated biosorbents from Albizia coriaria, Coffea canephora, Cyperus papyrus, Erythrina abyssinica and Musa spp were investigated for removal of selected trace metals from contaminated water in batch studies.

3. Pharmaceutical compounds; a new challenge for wastewater treatment plants
Sammanfattning : Analytical analyses conducted at the Himmerfjärden WWTP (285.000 PE connected) identified 70 pharmaceutical compounds belonging to different therapeutic classes. Such organic micropollutants at low detected concentration range of µg - ng l-1 did not affect the treatment processes at WWTP. LÄS MER
4. Condensation irrigation : a combined system for desalination and irrigation
Sammanfattning : Condensation Irrigation (CI) is a new irrigation method that combines desalination and subsurface irrigation by making use of saline water for supplying clean irrigation. In this system, solar stills are used for evaporating non-potable water, and the formed vapour heats and humidifies the ambient air above the water surface. LÄS MER
5. Water diffusion and free volume in hydrophilic polymers
Sammanfattning : During moisture uptake in polymers, the diffusion of the water molecules is believed to occur via unoccupied voids. These voids are called free volume cavities and their sizes are continuously altered when the moisture content in the polymer is enhanced. LÄS MER
