What is Wastewater Treatment?

Wastewater treatment is the process of converting wastewater – water that is no longer needed or is no longer suitable for use – into bilge water that can be discharged back into the environment. It’s formed by a number of activities including bathing, washing, using the toilet, and rainwater runoff. Wastewater is full of contaminants […]

Municipal wastewater

Wastewater is treated in sewage treatment plants. Biological and chemical processes as well as mechanical ones are used here. Most of the clogging material is caught by the screening system. Heavy matter, such as particles of sand that are being carried along, should settle here. The final station of the mechanical treatment stage is the […]

Industrial wastewater

Industrial wastewater refers to the wastewater that arises from industrial production processes (e.g. in the food, paper, chemical, textile, and metal industries). The composition of the industrial wastewater can vary greatly depending on which branch of industry is involved. Wastewater in the paper industry contains organic substances that are not easily degradable. Oils, greases, and […]

Swimming pool water production

Swimming pools include certain risks such as infections so that they must always have a guaranteed water quality. As a result, all swimming pools have to be continuously monitored and controlled. Water is primarily treated to kill or reduce the microorganisms within it (bacteria, viruses, etc.). This process can also be called disinfection or sterilization. […]

Brackish water and seawater

Desalination of brackish water and seawater According to UNESCO the supply of drinking water is highly problematic in many parts of the world. A limited amount of water is available on our planet and 97.5 % of the water in the world is salty. Because the availability of drinking water is limited, seawater is an […]

Groundwater

Where does our drinking water come from? Drinking water treatment refers to the treatment of spring water, surface water, or groundwater. Spring water refers to water that emerges out of the earth from underground water sources. Surface water is taken from standing or flowing bodies of water above ground. Dam reservoir water, lake water, and […]

Liquid distillation system

Distillation is a process of separating the component substances from a liquid mixture by selective vaporization and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components of the mixture. In either case the process exploits differences in the volatility […]

Sulphur recovery plant

Sulfur is a component of coal and other gasification feed stocks. Resulting sulfur compounds in syngas need to be removed in most gasification applications due to environmental regulations or to avoid catalyst poisoning. Whether it is electricity, liquid fuels, or some other product being output, sulfur emissions are regulated, and sulfur removal is important for […]

Vapour recovery system

Vapor (or vapour) recovery is the process of recovering the vapors of gasoline or other fuels, so that they do not escape into the atmosphere. This is often done (or required by law) at filling stations, in order to reduce noxious and potentially explosive fumes and pollution. The negative pressure created in the (underground) tank […]

Oily water treatment

Solids and oil separation technologies have been used across a range of applications, at installations both onshore and offshore. Including: • Produced water – recovered during the separation of crude oil. • Desalter water – generated during crude oil washing. • Ballast water – for incoming sea tankers. • Terminal and refinery process drainage – […]
