Desalination Desalination processes using thermal technologies, such as multistage distillation (MSF), multiple effect distillation (MED) and vapor compression (VC), utilize heat and reduced pressure to vaporize and condense pure water from seawater. Thermal desalination is also used in industrial applications. Desalination is a technology that separates dissolved salts and other…
Ultraviolet systems (UV) Ultraviolet or "UV" is a type of energy found in the electromagnetic spectrum, lying between x-rays and visible light. Although we cannot see UV light or rays, we are exposed to them every time we step out into the sun. In fact, UV light is responsible for…
Water harvesting (Agriculture and Domestic use) Containment of Contaminants that will affect the environment Anaerobic, Facultative, Aerobic and Maturation/Oxidation Ponds (Sewage treatment)
Sedimentation As the water and the floc particles progress through the treatment process, they move into sedimentation basins where the water moves slowly, causing the heavy floc particles to settle to the bottom. Floc which collects on the bottom of the basin is called sludge, and is piped to drying…
Evapotranspiration (ET) systems are a method of dispersing effluent through evaporation (the change of liquid into vapor that passes into the atmosphere) or transpiration (the passage of water through a plant from the roots through the vascular system [stems and leaves] to the atmosphere). ET systems are designed for full…
A biodigester is an anaerobic tank (oxygen-free), which digests organic material biologically. It is used to treat black water (human waste) on site, eliminating pathogens and malignant bacteria, so the treated water can be used for irrigation. In addition, when organic material decomposes without oxygen, it produces methane, a potent…
A reed bed is essentially a channel, lined with an impermeable membrane, that is filled with gravel and planted with macrophytes i.e. reeds, rushes (Figure 2) and used to treat wastewater. Wastewater, black or grey, is passed through the root zone of the reeds where it undergoes treatment. Inlet and…
