(Semi-)centralised Drinking Water Treatments
Advanced Oxidation Processes
Hazardous organic waste, widely spread in water by industrial, military and domestic sources, is an emerging issue. Advanced Oxidation Processes (…
Treatment Plant Set-up
Centralised drinking water treatment plants treat large amounts of water from many households in one single spot and consequently most often require…
Slow Sand Filtration
Slow sand filtration is a type of centralised or semi-centralised water purification system. A well-designed and properly maintained slow sand filter…
Rapid Sand Filtration
Rapid sand filtration is a purely physical drinking water purification method. Rapid sand filters (RSF) provide rapid and efficient removal of…
Bank Filtration
Bank filtration is the infiltration of surface water, mostly from a river system into a groundwater system induced by water abstraction close to the…
Sedimentation (centralised)
Sedimentation is a simple, physical pre-treatment of water prior to application of other purification treatments such as filtration and disinfection…
Adsorption (Activated Carbon)
Activated carbon filtration is a commonly used technology based on the adsorption of contaminants onto the surface of a filter. This method is…
Membrane Filtration
Membranes are thin and porous sheets of material able to separate contaminants from water when a driving force is applied. Once considered a viable…
Coagulation-Flocculation
Coagulation-flocculation is a chemical water treatment technique typically applied prior to sedimentation and filtration (e.g. rapid sand filtration…
Ion Exchange
Ion exchange is a water treatment method where one or more undesirable ionic contaminants are removed from water by exchange with another non-…
Chlorination (centralised)
As an effective yet inexpensive disinfectant, chlorination is the most commonly used disinfection method in drinking water treatment plants all over…
Ozonation
Ozonation (also referred to as ozonisation) is a chemical water treatment technique based on the infusion of ozone into water. Ozone is a gas…
H2O2
Hydrogen peroxide (H2O2), a colourless water-like liquid, is one of the most versatile, reliable and environmentally friendly oxidising agents. The…
Desalination
The chemical process of changing seawater into potable or fresh water is called desalination. Thermal distillation and membrane processes are the two…
