World Water Day

22. March 2022

Today is World Water Day

Water is one of the most precious resources on our planet.

Only 2.5% of the water on earth is fresh water. Only a small part is really accessible for us humans, namely 0.3% (in lakes, rivers and dams).

Zero Liquid Discharge (ZLD) clean water - cleaning processes and drinking water

The necessary focus on the conservation and protection of our water resources ensures a constant optimization with regard to the use and disposal of water in industry. The machine solutions developed by SIEBTECHNIK TEMA for Zero Liquid Discharge (ZLD) projects are used in many industrial sectors to clean or recycle process water and to recover valuable substances from wastewater.

To improve the environmental performance of industrial plants, ZLD is used in a wide range of industries, such as power generation, pharma, steel or (petro) chemical industry.

The solid-liquid separation is the crucial last step in most ZLD processes, because here the remaining water is separated from the solid, in most cases salts.

Dewatering is usually done with decanters, SHORTBOWL decanters, pusher centrifuges and CONTURBEX centrifuges. For dewatering of coarse residue, our HSG vibratory centrifuges have proven successful.
