Water is a vital resource, bit only 3 % of the water on our planet is fresh. Of these reserves, just 10 % can be exploited economically. It is estimated that 1.1 billion people lack access to clean drinking water and there is a water shortage in already 30 countries. Water is the most vital raw material of the 21st century. Accordingly, a secure water supply is regarded as one of the most important global objectives for the coming years.
Today, a secure drinking water supply is impossible without the use of the latest technology in many locations. Innovative technologies for the treatment of drinking water as well as water reuse are gaining in importance in all the world’s regions.
Omnicorp has responded to this challenge with a comprehensive and highly qualified range of solutions and offers a wide spectrum of chemical, physical and biological processes for the water treatment in line with the different water sources:
• Ground water
• Surface water
• Sea and brackish water
• Treated wastewater (potable water reuse)
We design and build plants of the highest standard and contribute to the prevention and removal of environmental loads through the realisation of our scientific know-how and constant process development work.
Water withdrawn from the natural environment is subjected to several types of treatments.
• Coarse and fine screening. The water is filtered first through a screen to catch the biggest particles, then through a fine-mesh sieve to trap smaller ones.
• Flocculation and settling. A coagulant is added to the water to cause the remaining waste—dust, dirt particles, etc.—to clump together. These flocculates sink to the bottom of the settling tank. Some 90% of suspended particles are eliminated in this way.
• Filtration. The water flows through a filter, fine sand bed and/or active carbon filter. Sand filtration eliminates matter still visible to the naked eye. Active carbon filters trap micro-pollutants such as pesticides. There are even more advanced filtration processes, such as membrane filtration.
