Water treatment

Water treatment is any process that improves water quality to make it appropriate for a specific end-use. It consists of several mechanical and chemical processes that remove water contaminants. The processes remove contaminants and undesirable components. It can also reduce their concentration, making the water fit for its desired end-use. This treatment is crucial to human health and allows humans to benefit from drinking and irrigation.

Water treatment optimises most water-based industrial processes, so operating costs and risks are reduced. Poor treatment processes allow water to interact with the surfaces of pipes and vessels. Steam boilers can scale up or corrode. These deposits will mean more fuel is needed to heat the same amount of water.

The contaminants can be solid or dissolved and include metals, minerals, organic substances, viruses, bacteria, and fungi. Basic processes include coagulation, flocculation, sedimentation, filtration and lastly, disinfection of water.

Water treatment technologies are used to treat water intended for drinking, recycling or water discharges to be released into the environment. They can also be employed to prevent corrosion, scaling and bacterial development in various industrial processes. Water is a precious resource and water regulations are very stringent.

Water treatment lit up with UV at Happy Valley

The southern hemisphere’s largest Xylem-manufactured drinking water ultraviolet disinfection and water treatment system has kept pathogens at bay. After more than six months, it has protected the safe, clean drinking water supply for nearly half a million South Australians. Read More
Removal and recovery of ammonia from simulated wastewater using Ti3C2Tx MXene in flow electrode capacitive deionization for water purification

A new frontier in water purification

One in three people worldwide lacks access to clean drinking water and basic sanitation services. These problems have only increased across the world due to the effects of climate change. Developing countries and vulnerable communities are the most affected by the adverse effects of water scarcity and a lack of access to water purification facilities. Read More
