Luisenthal drinking water treatment plant
Luisenthal drinking water treatment plant after reconstruction and extension
Reconstruction and process engineering extension of the drinking water treatment plants of Luisenthal and Tambach-Dietharz for the Thuringia Long-Distance Water Supply.
The Luisenthal project includes the complete structural and technological reconstruction of the now 30-year-old plant, which also includes the replacement of steel pipes of DN 50 to DN 600 by stainless steel pipes (up to nominal widths of DN 100) and by aluminium-Rilsan pipes (up to nominal widths of DN 600).
The process engineering extension of the Luisenthal DWTP relates particularly to a hardening of the barrage water to approx. 5°dH according to the Reinerzauer procedure, a split-stream hardening method through Dolomite filter material, a more thorough reduction of clouding through dual-layer filtration and optimised flocculation plant and an improvement in sludge treatment.
Die rated water volume of the Luisenthal plant is 90,000 m³/d, the treatment volume of the Tambach-Dietharz DWTP 65,000 m³/d. The Luisenthal DWTP forms the core of the distant water supply system in North Thuringia and supplies c. 800,000 inhabitants.
