Wastewater treatment technologies

Scientists have discovered many advanced wastewater treatment technologies. Applicable to many different types of wastewater. So what are the wastewater treatment technologies, let's follow Biofix!

Physico-chemical wastewater treatment technology combined with biology

This technology has been around for a long time, but its popularity is still widely used today.

The mechanism of the physico-chemical method is to introduce a certain reactant into the wastewater. This substance reacts with the dirt in the wastewater. The resulting substance is a solid that can be removed from the water through sediment, or a soluble form that is not harmful to the environment.

Commonly used physico-chemical treatment methods: coagulation, adsorption, extraction, sedimentation, ...

MBR biological membrane treatment technology

MBR (Membrane Bio-Reator: biological filter tank using membrane) is a system for microbiological treatment of wastewater using membrane filtration technology.

The application of MBR membrane filter is a combination of membrane filtration technology and biological tank. It is a step in the wastewater treatment process that can replace the role of separating the residue of the secondary sedimentation tank and the input water filter tank. Therefore, it is possible to eliminate the secondary sedimentation tank, the disinfection tank and operate with a higher MLSS concentration, which will save the area of ​​the biological tank.

The application of MBR membrane filter technology gives better and more stable water quality after treatment than traditional microbiological technology. The treated water can be reused.

AAO treatment technology

What is AAO treatment technology?

A/A/O technology stands for Anerobic - Anoxic - Oxic. AAO technology is a continuous biological treatment process, combining 3 microbiological systems: anaerobic, anoxic, aerobic to treat wastewater. Under the impact of decomposing pollutants by microorganisms, wastewater will be treated before being discharged into the environment

Advantages of AAO technology:

Low investment and system costs include: construction, air blowers, submersible mixers, pumps, ...

Generates less sludge than other aerobic biological technologies

Water quality meets A or B standards, depending on the design goal

Low energy consumption

MBBR wastewater treatment technology

What is MBBR technology?

MBBR (Moving Bed Biofilm Reactor) technology is a combination of two techniques: microorganisms attached to fixed materials and suspended microorganisms. In this technology, wastewater is first treated in the MBBR tank. Then in the traditional activated sludge equipment.

This combination has optimized MBBR to reduce BOD in wastewater by 45-70%. Before entering the activated sludge treatment equipment in the back. The activated sludge design is designed to be smaller, because it only solves the problem of treating organic substances.

The activated sludge is circulated from the secondary sedimentation tank to the head of the activated sludge tank, provisions can be provided to allow a part of the activated sludge to be circulated to the MBBR tank. Therefore, it is possible to create a collection tank that is effective for controlling the phenomenon of floating microorganisms. Other advantages of MBBR technology are the ability to withstand sudden increases in input load as well as other toxic compounds.

MBBR technology is optimized for a small land area treatment area, suitable for the requirements of high quality wastewater discharge with large loads, as well as for future expansion of the treatment scale.

Advantages of MBBR technology:

• 
  Withstand high organic loads, 2000 -10000gBOD/m3 day, 2000 - 15000gCOD/m3 day.
  BOD treatment efficiency up to 90%
  Remove Nitrogen in wastewater
  Save space
