ENNI – Drinking water softening plant in Moers

Drinking water softening plant with downstream turbidity filtration. The softening plant serves to reduce the degree of hardness in the raw water from approx. 21°dH to the hardness range 12-14° dH. and thus supplies water in a moderate hardness range. The total treatment capacity is about 24,000m3/d. The plant consists of:

• 2 pieces of fast decarbonization reactors with a treatment capacity of 10.800m3/d each
• 4 pieces turbidity filter Ø 4.500 mm
• Fully automatic supply of the softening process with quartz sand as seed grain
• Drainage, storage and disposal facilities for the residues from the softening process
• Fully automatic quicklime slaking plant for the production of the lime-milk suspension required for the process, including metering technology
• Peripheral storage and dosing systems for phosphate (PO4), caustic soda NaOH) flocculants (FHM) and carbon dioxide (CO2)
