Clean and safe drinking water is a basic human need and providing it for everybody would be the greatest achievement by 2025. Out of 6 billion people on earth not more than one six lacks access to potable water. Also of the total water resources only 1% of fresh water is available for human consumption. To solve this problem, the means and ways have to be explored to reduce, reuse and recycling of water we have. Recycling of water using Solar Still is one of the popular and economic methods.

Nowadays ultrafiltration (UF) technology is also available, but the question is, to which extent and how cost effectively can it address the SWRO pretreatment need. Hence, the question is to which extent do market needs and technology capabilities match.

The Leopold Clari-DAF system is a proven, highly effective method of removing turbidity, insoluble metals (iron, manganese, arsenic), algae, color, taste and odor, Giardia, Cryptosporidium, and other low-density particulates from water. Its peformance is superior to gravity sedimentation in providing consistent quality effluent, producing consistently high sludge solids, and operating at high loading rates-results that can lower the total cost of operation.

More than 500 plants around the globe have so far been equipped with the patented technology and the projects that rely on this German-made ultrafiltration technology are steadily increasing in size and spreading across the world.
