Waste Water Treatment
GEA Messo PT has devoted special attention to the environmental protection and to the recovery of the solute or water from waste waters for more than 50 years. Design and supply of the plants feature the following criteria:

• Volume reduction to reduce transport, downstream treatment and landfill costs
• Recovery of particular components from the waste solution mixtures
• Recycling of water from the waste solution mixtures
• Evaporation to dryness (ZLD).

GEA Messo has designed, supplied and commissioned numerous plants for regeneration of spin and pickling bath liquor in the below listed fields:

• Regeneration of spin bath liquor
• Regeneration of pickling bath liquor
• Treatment of scrubbers liquors from flue gas cleaning after garbage incinerators or
• power stations
• Treatment of salt slags from the secondary aluminium melters
• Treatment of various industrial purge streams
• Food industry waste water concentration
• Ammonium sulphate recovery from production effluents.

Recycling of the water has a positive effect on all aspects of your plant's economy. This is especially valid in the food industry, where the concentration of the biomass permits to downsize the final treatment unit (either a biological fermentation or a chemical treatment) considerably.

The ZLD processes for the liquid effluents from flue gas scrubbers are characterized by; recovery of Sodium chloride or Calcium chloride dihydrate from the scrubber liquor for re-use in the Chemical Industry. The recovered process water can be re-used as make-up water for the internal water supply.
