Techniques

Chapter 1: Techniques Employed in Quadrasep

The Quadrasep system harnesses the power of four distinct separation techniques, each contributing to the overall purification of wastewater. These techniques, working in synergy, provide a comprehensive and efficient treatment approach:

1. Microfiltration (MF):

  • Mechanism: Microfiltration involves the use of membranes with pore sizes ranging from 0.1 to 10 micrometers. These membranes physically sieve out suspended solids, including bacteria, viruses, and larger particulate matter.
  • Benefits: MF removes microorganisms, improving water quality for discharge and reducing the risk of waterborne diseases.
  • Applications: Widely used in the treatment of municipal wastewater, industrial effluents, and drinking water.

2. Ultrafiltration (UF):

  • Mechanism: UF utilizes membranes with smaller pore sizes (typically 0.01 to 0.1 micrometers) to remove dissolved organic matter, smaller particles, and larger molecules.
  • Benefits: UF further purifies the wastewater by removing substances that MF cannot capture, improving water clarity and reducing turbidity.
  • Applications: Applicable in a range of wastewater treatment scenarios, including industrial applications, pharmaceutical production, and food processing.

3. Reverse Osmosis (RO):

  • Mechanism: RO employs a semi-permeable membrane under high pressure to separate water molecules from dissolved salts, ions, and other contaminants. The membrane selectively allows water molecules to pass through while rejecting other substances.
  • Benefits: RO achieves high purity levels, making it ideal for producing potable water from contaminated sources.
  • Applications: Widely used in desalination, industrial water treatment, and municipal water purification.

4. Electrodialysis Reversal (EDR):

  • Mechanism: EDR uses an electric current to selectively remove dissolved ions from the wastewater. The process involves a series of ion-exchange membranes that separate ions based on their electrical charge.
  • Benefits: EDR is particularly effective in removing dissolved salts, making it suitable for high-salinity wastewater and desalination applications.
  • Applications: Used in industrial wastewater treatment, desalination, and the production of high-purity water for specific industries.
