Pattani Technology

The Plant Design


Pattani Purification Plants are specifically designed to suit the special needs and environmental conditions of small or remote communities.

The system is tailored to each location, taking into account:

 

  • Source water characteristics – Is the raw water surface water or ground water? What is the raw water composed of?

  • Flow rate – How fast does the water flow from its source?

  • Microbiology – What pathogens are present?

  • Flocculation disposal – Where can waste products be disposed of safely?

  • Community requirements – How much water is needed per day?

  • Access – Where will the unit go and is electricity available?

 

 

The Purification Process

Pattani Purification Plants treat raw water through sevens steps:

 

  1. Flocculation – the removal of suspended solids

  2. Oxygenation – the removal of solid iron compounds

  3. Sand Filtration – the removal of all precipitated and finely suspended particles

  4. Mixed Bed Filtration – secondary filtration of sand particles, and pH control

  5. Reverse Osmosis – the removal of salts

  6. Activated Carbon – absorption of heavy metals

  7. UV Sterilisation – destroys all disease causing pathogens

  8. Optional chlorination of water – this is only necessary if water is to be stored rather than used immediately. In tropical environments this step is recommended.
