SIF is a leader in developing and implementing chemical free water technologies which are totally eco-friendly. Here is a quick glance at the company’s past accomplishments, key technologies as well as the markets and industry sectors we have impacted.

Essential Facts
Who is SIF?
SIF is a quality water treatment company in the Asia Pacific region where the founders have with them more than 20 years of experience in chemical free water treatment processes. Since 2005, SIF has recycled more than 500 million litres of water.

How does SIF stand out from other water treatment companies?
  • SIF advocates chemical free water treatment.
  • SIF holds its own proprietary technology.
  • SIF does not own filtration or membrane-related water technologies.

    What treatment system does SIF use?
    SIF uses a patented water treatment technology termed the DPA system that was developed based on the principle of Cavitation.

    What is cavitation?
    Cavitation phenomenon is known in science and technology for more than hundred years. An English scientist called Reynold was the first to discover this phenomenon in 1894 on the English torpedo boats.
    Cavitation results in the following:
  • Sterilization of a liquid processed
  • Emulsification of products not usually mixed (e.g. oil and water)
  • Disruption of long polymer chains in mineral oils, their transition into a new structural condition
  • Size reduction (dispersion) to micron level of solid particles in a liquid
  • Intensification of chemical reactions into tens and even thousand times

    Cavitation is typically used for:
  • Mixing
  • Emulsification
  • Sterilization

    What is the difference between traditional Cavitation and DPA Technology?
    Traditional Cavitation is characterized by:
  • High energy usage
  • Problem of cavity damage
  • Usually requires a separate motor
  • Heavy maintenance

    DPASYS® cavitation process:
  • Does NOT REQUIRE any electricity to work
  • There is zero incidence of cavity damage
  • Works purely on circulation water flow-rate
  • Minimum maintenance required

    What are the benefits of using DPA Technology?
    Some immediate benefits arising from the technology include, but not limited to:
  • Increase in dissolved oxygen (DO)
  • Inhibition of harmful bacteria growth
  • It is a chemical-free treatment solution
  • No electricity is required – truly a plug-and-play solution
  • Minimum maintenance required.

    In which industries have the DPA been applied?
  • Aquaculture
  • Agriculture
  • Food processing industry
  • Oil & Gas Sector
  • Marine / Shipping Industry
  • Housing / Infrastructure
  • Hospitality Sector
  • Mining Sector
  • Pharmaceutical Industry
