Microbiological Tests and Pilot Plants Studies

Microbiological Tests

  • Enumeration of Indicator Organisms (MPN or MF method):  total coliform, fecal coliform, and   fecal streptococcus.
  • Total Plate Count
  • Special microbiological studies on request
  • DNA extraction and purification
  • DNA amplification and sequencing for microbial community analysis

Pilot Plant Studies

  • Biological oxidation (activated sludge, tricking filter, RBC, lagoon, nitrification, denitrification, and sludge digestion)
  • Carbon adsorption (batch & column)
  • Chemical oxidation
  • Coagulation & flocculation (Jar test)
  • Disinfection (chlorination & ozonation)
  • Membrane process (reverse osmosis & hyper filtration)
  • Oxygen transfer and aeration
  • Solids sedimentation
  • Solidification and stabilization
  • Sludge conditioning and de-watering (vacuum filtration and pressure filtration)
  • Water softening
