In general context, water is THE critical natural resource upon which all social, economical and ecosystem functions depend.

Only about 1% of the total Earth’s water can be classified as directly accessible fresh water. A fast growing population, a dramatic increase in environmental pollution and the climatic change are the big current global challenges when it comes to water supply. An increased water demand, declining water source qualities, flood and drought as well as extreme weather situations are the key reasons for a scarcity of water in the future.

Providing clean, fresh, accessible water through treatment of raw water across the globe will become a top priority for governments, states and private entities alike.

As a result, water suppliers are not capable to fully cover demands today, let alone tomorrow. It is absolutely vital that new and improved purification technologies are being developed besides considering alternative water resources to satisfy future demand.

Cleaning of water sources like seawater, groundwater, surface water, and sewage is challenging. The technology involved in the process has not been developing as fast as demand, regulations and pollution have been rising. Presently, water treatment facilities have to choose between high water quantity with a moderate degree of quality, or high water quality with a high percentage of water loss due to limitations in purification technologies.
