Conventional water treatment system vs Ceraflo® MBR

1. Principle

Ceraflo® Membrane Bioreactor (MBR) is a combination of moving bed bioreactor (MBBR) and conventional membrane bioreactor (MBR). The contaminants are removed by MBR through physisorption, biochemical reaction and physical filtration. Micro-bio-substrate is added to adsorb pollutants such as heavy metals. Besides that, it acts as a carrier to allow biofilm to grow. Contaminants such as COD, BOD, TN, TP and oil will be degraded by various bacteria consortium (e.g. aerobic bacteria, nitirifier, denitrifier, phosphorus accumulating bacteria, etc). The remaining contaminants will be rejected by the membrane and resulting in high quality product water.

2. Configuration

Similar with conventional MBR, it has the advantage of configuration flexibility. Ceraflo® MBR can be configured into (a) side-stream MBR, where membrane systems are arranged outside of biological tank, and (b) submerged MBR, where the membrane systems are submerged into biological tank.

3. Ceraflo MBR advantages and application

Ceraflo MBR system with modified hydrophilic UF membrane is specially designed to decrease membrane fouling rate and energy consumption. In addition, the micro-bio-substrates provides a large surface area for biofilm to grow quickly, becoming a granular bacteria consortium with non-sticky feature. The advantages are as below:

  • Stable operation
  • Rapid start-up
  • Lower operating expenditure (OPEX)
  • Lower membrane fouling rate
  • Higher bacteria concentration with lower tank volume requirement
  • High contaminant loading capability
  • Flexible and compact design with small footprint
  • The combined system removes combined COD, solids and nutrients in a single unit
