Membrane bioreactors

Membrane bioreactor (MBR) is the combination of a membrane process like microfiltration or ultrafiltration with a biological wastewater treatment process with the activated sludge process. It is now widely used for municipal and industrial wastewater treatment. The membranes are used to perform the critical solid-liquid separation function. In activated sludge facilities, this is traditionally accomplished using secondary and tertiary clarifiers along with tertiary filtration. MBR processes can produce effluent of high quality enough to be discharged to coastal surface or brackish waterways or to be reclaimed for urban irrigation.

Greentech Membran- Bioreaktor

  • - The membrane is welded on rigid frame.
  • - Filter plates are continuously aerated through bubble diffusers to keep them clean.
  • - The membranes do not need regular chemical cleaning.
  • - Compact package systems in 40` containers (up to 1000 m³/day water can be filtered).
  • - Fast delivery and start-up due to the compact design.
  • - Swiss quality equipment.
  • - Effluent with irrigation water qualities.
  • - Minimum construction work on site and easy to relocate.

Advantages

  • - Capable of meeting the most stringent water quality requirements.
  • - Effluent with irrigation water qualities.
  • - Good price-performance ratio.
  • - Low maintenance and minimum operation requirement.
  • - Higher biomass concentrations are allowed than with conventional systems (dry matter content: 9 - 16 g / l).
  • - Lower tank volumes (up to 75%) due to increased biomass concentration.
  • - Less foot print.
  • - Reduced downstream disinfection requirements.
  • - Modular expandability, configuration flexibility.

Application

  • - Municipal wastewater treatment.
  • - Wastewater reuse for irrigation, toilet flushing.
  • - Decentralized wastewater treatment: camps, hotels, parks, military bases, building complexes.
  • - Industrial wastewater (food, beverage, pharmaceutical).
