The sewage plant Phuket		 Phase 1: Feasibility Study
  • Pre-investigations for transfer and adaptation of sewage sludge dehydration and mineralisation in reed beds to Thailand conditions
  • Selection of a suitable sewage plant
  • Feasibility investigations
  • Literature research
  • Selection of an privatized operation model
  • Economical test and Financial concept
From 25 potential locations the sewage sludge plant Phuket was selected for performance of the phases 2 and 3. At this sewage sludge plant the feasibility of a KSVE (phase 1) regarding technical and economical criteria was tested. The expenses of a KSVE and potential of savings for Phuket as well as further sewage plants were tested. Operating a KSVE instead of mechanical dehydration with deposit of the sludge can lead to cost savings of approx. 80% in comparison to the present situation.

Sludge pit		 Phase 2 + 3: 

With the positive results from phase 1 the preconditions for realization of a pilot scale sludge treatment unit (phase 2) and a large scale unit (phase 3) in Thailand were found out.
