This study concerns the community involvement in water resource management in Namaacha City in Mozambique. The city has approximately 16 000 inhabitants. In 2005, the World Bank invested in new infrastructure for the water provision of the city, and water supply is since then handled by a private company. Water provision in the city is […]

Phosphates are fixed in the enhanced biological phosphorus removal process and released from the Bio-P sludge in the digesters. The supernatant from digesters with large quantities of phosphate should be treated before it is recirculated to the treatment system to prevent phosphorus over-load in the system. Brackish seawater is concentrated to bittern for struvite precipitation; […]

Water and salt mass balances for the Dead Sea were modeled. Precipitation, evaporation, river discharges, ground water flows, input/output from potash companies and salt production, and brine discharge were included in the models. The mixing time in the Dead Sea was modeled using a single-layer (well-mixed) a two-layer (stratified) system. Using the single-layer approach the […]

Can wastewater treatment contribute to counteract global warming? Increased biogas production for substituting fossil fuel is one possibility. However, an active sludge process with biological nitrogen and phosphorus removal consume organic material, gives a sludge with less digestibility and need energy for aeration. The amount of produced sludge corresponds to half of the organic material […]
