During the period 1840–1940, a large number of lakes in Sweden were drained or the water tables lowered. The driving forces behind these projects are discussed and the most important reasons behind them identified. A change in land ownership from collective towards private and undisputed control stimulated farmers to invest in improvements in the arable […]

Syria, as well as many other countries in the Middle East, faces serious water shortage problems. Available water per capita (AWPC) will dramatically decrease due to climate change, population increase, and water needed for economic growth. Rainwater harvesting can play an important role in increasing available water in Syria. However, the absence of rainwater sewer […]

One option for coping with wasteful uses of fresh water in landscape irrigation is to use the treated greywater (GW). In the present study, an evaluation of a simple treatment system for reusing GW to irrigate green areas, trees, and ornamentals all over the campus in Tafila Technical University (TTU), Jordan, is presented. After 12 […]

A two-dimensional multi-fluid flow experiment was performed in a container (45 cm x 54 cm x 20 cm) filled with fine sandy soil. A dye stained light nonaqueous phase liquid (LNAPL) was applied in four releases over a rectangular area of 5 x 20 cm at the center of the soil surface. The releases varied […]

Many waste water treatment plants in Sweden needs to improve the nitrogen removal in the coming years in order to fulfill stringent regulatory requirements with respect to nitrogen in the final effluent from today’s level of 15–20 mg/l to 8–10 mg/l. At waste water treatment plants having anaerobic digesters, the nitrogen content in the reject […]
