Turbo LME Process for Water Treatment Plants

The Challenge

Providing clean water to people

Motivation of effective clarification:

  • In the treatment of surface water, the effectiveness of the first clarification process is decisive for a cost- and resource-efficient water treatment plant.
  • Effective clarification ensures both a high degree of operational safety in downstream treatment steps and hygienically perfect drinking water quality.
  • The clarification shall also be cost-effective with regards to the consumption of chemicals and the required construction volume.

CNP’s Solution

Compact, precisely adjusted and integrated process for clarification

The ECoFlocX process:

ECoFlocX stands for Enhanced Coagulation, Flocculation, and X for removal by lamella settling and integrated thickening.

  • The process is mainly used for clarification

  • In general it can also be used for any precipitation, e.g. partial softening/decarbonization, Fe-phosphate precipitation, lime saturation, etc.

  • Multi-chamber flocculation: All phases (coagulation, contact sludge, polymer mixing, flocculation) take place separately and specifically designed in their own stage

  • A special feature is the horizontal paddle unit in the flocculation stage, which is very advantageous from a hydraulic and process engineering point of view

  • Contact sludge flocculation to accelerate floc formation 

  • Sedimentation takes place via lamella clarifier or lamella clarifier with integrated thickener

  • A special feature of our lamella is the crossflow at the inlet to the lamella package and the hydraulically controlled overflow at the upper end

Benefits

ECoFlocX Process

  • Particularly suitable for efficient high suspended solids removal in order to get high-level and stable water quality
  • Very compact design due to short residence times in coagulation/flocculation
  • and high specific settling area (>10 m³/m²)
  • Minimized chemical consumption for coagulant/precipitant,
  • lime milk and flocculant.
  • Adjustable weirs at lamella overflow ensure uniform up-flow and
  • steady floc separation without ballast additives.
  • Each single plate is easily removable without interruption in operation
  • Suspended solids and turbidity removal of 3-4 logarithm scales resulting
  • in a clarified water quality of less than 1 NTU turbidity.
  • In case of downstream sand filtration: extended filtration cycles and less backwash water losses.
  • In case of downstream ultra filtration: less fouling and higher filtrate yield.
