BioPM - An outstanding solution to organic industrial wastewater treatment, it is especially effective when applied to processing and manufacturing enterprises whose wastewater has a high organic content from plants and animals.

BioPM (Biofilter for production & manufacturing) is an organic industrial wastewater treatment solution by filtering through microbiological membranes, with superior efficiency compared to traditional microbiological sludge method, high filtration efficiency makes water easy easily reach A or reusable with large input fluctuation threshold. In addition, this solution does not require strict control of viscosity and microbial density, does not require reflux or sedimentation, helping the operator to be freed from many responsibilities.

1. Who is BioPM suitable for?

  • BioPM is particularly effective when applied to processing and manufacturing businesses whose wastewater sources have a high organic content of plants and animals (usually BOD/COD ≥0.2), for example:
  • Enterprises processing food and aquatic products
  • Enterprises producing beverages and alcohol
  • Coffee manufacturers
  • Industrial parks, businesses with high number of employees
  • Municipal domestic wastewater treatment system.....

2. What value added does BioPM bring to customers?

  • Construction cost is reduced by 50% due to extremely small basin volume
  • The cost of sludge treatment is very low, because the amount of sludge generated is much less than that of the suspended microbiological sludge method. Some projects have been implemented this method even without the sludge basin due to very little sludge, which helps saving operating costs
  • Overcoming difficulties when the input pollution concentration is not balanced (COD/TN, BOD/TN)
  • Low power consumption due to optimized flow and dynamics design
  • Thoroughly treating TN in wastewater thanks to anaerobic microbial membrane formed in the filtration layer
  • It can eliminate the foaming phenomenon in the output effluent when the amount of surfactant (e.g. detergent, soap) is high, the effect of surfactant treatment is better than the activated sludge method and the MBR filter
  • Withstands up to 20% -30% of input fluctuations in capacity or concentration
  • Create a suitable environment to select natural microorganisms, retain microorganisms with high sludge lifetime, and eliminate fast-growing and difficult-to-settle microorganisms when being discharged into the environment.
  • Increase the efficiency of gas distribution of the distribution system when discharging from the wastewater environment to microorganisms due to the gas flow in zigzag, not straight lines.

3. How does BioPM work?

  • BioPM treats pollutants through biofilter basins, including part or full of filtration steps: anaerobic filtration, anoxic filtration, aerobic filtration. Water flow is designed from the bottom up. After going through these filters, organic pollutants and nutrients are thoroughly treated to satisfy A-QCVN40: 2011/BTNMT standards.
  • Because of the filtration mechanism, the treatment system does not require sedimentation basins before being discharged into the environment. Sludge is maintained in the filter layer instead of floating in wastewater, so the water quality is stable even when sludge is not capable of forming particles or has good sedimentation, reducing complexity in transportation compared to current activated sludge technology.
  • The difference when applying BioPM to different types of production wastewater is in the pretreatment step (level 1 treatment), depending on the specific nature of the wastewater, the pretreatment steps will be designed accordingly.

4. What is the required volume for the processing system?

  • The volume will be optimally designed based on: (i) size of discharge, (ii) nature of continuous discharge or at a specific time, (iii) the pretreatment steps depending on the characteristics of wastewater, for example: screening, regulating PH, etc. (iv) concentration of COD in wastewater and (v) actual customer space.
  • To save space, the micro-filtration layer can be designed to increase the density of microorganisms to be treated; thereby helping the amount of pollutants that can be treated per 1m2 of basin increase. Usually the volume is ~ 1.2Q - 2Q (Q = discharge capacity / day and night). If the wastewater is particularly polluted, (e.g. COD ≥ 10,000mg / l), the retention time will be higher.
