Panta Rei, Zero Discharge Effluent Treatment Plant, Biological Treatment, Ultrafiltration, Nanofiltration, Reverse Osmosis

Description

  1. Overview
    1. Series of treatments to recycle water and dispose of residual matter, complying with company policies or local regulations to avoid any final discharge
    2. Provides proper biological treatment for degradation and reduction of main pollutants such as BOD, COD, and suspended solids
  2. Process Stages
    1. Filtration and preliminary treatment stage is set
    2. Membrane treatment follows the process line
    3. First section is made of an ultrafiltration treatment to guarantee fine removal of suspended solids and protect the following membrane treatment steps
    4. Nanofiltration section performs color removal, while rejecting also some bivalent components such as calcium and sulfates, reducing the hardness and sulfate concentration of the effluent
    5. Reverse osmosis section reduces the total dissolved solids concentration and all the residual pollutants to produce high quality water suitable for reuse in the dyeing process, the boilers, or any other application requiring high purity water
