Wastewater treatment

Wastewater treatment is the process of converting wastewater into water that can be discharged back into the environment.
  • Wastewater treatment removes contaminants from wastewater and converts it into an effluent that can be returned to the water cycle.
  • The effluent, once returned to the water cycle, either has an acceptable impact on the environment or is reused for various purposes (known as water reclamation).
  • The treatment process occurs in a wastewater treatment plant.
  • Different types of wastewater are treated at specific wastewater treatment plants:
  • Domestic wastewater (also known as municipal wastewater or sewage) is treated in a Sewage Treatment plant.
  • Industrial wastewater is treated in either a separate Industrial wastewater treatment plant or in a sewage treatment plant after pre-treatment.
  • Wastewater treatment plants are categorized based on the type of wastewater they treat.
  • Various processes, including physical, chemical, and biological treatment, are used depending on the type and extent of contamination.

Types of wastewater treatment plants include:

  • Sewage treatment plants
  • Industrial wastewater treatment plants
  • Agriculture wastewater treatment plants

Membrane bioreactor

An MBR Sewage Treatment Plant is an advanced method for wastewater treatment that combines membrane filtration and biological treatment. This process integrates ultra/microfiltration membranes with an activated sludge system, replacing the need for secondary sedimentation tanks and sand filters in conventional systems. The semi-permeable membranes are submerged in aerated reactors, allowing high-quality sewage filtration and eliminating the need for traditional sedimentation and filtration steps. Fine screening or pre-treatment is done before waste enters the membrane tank to protect and extend the life of the membranes.

The highlights of our MBR Sewage Treatment Plant are as follows:

  • Our product includes an online backwash system for uninterrupted operation.

  • It can produce a high-caliber of treated water.

  • It is designed to decrease the associated costs and chemical utilization.

  • It does not require a separate settler, clarifier, and polishing unit.

  • It is flexible in the sense that it can do both underground and above the ground.

  • It is eco-friendly.

  • Automobile industries

  • Oil & gas companies

 

  • Applications of membrane bioreactor

  • Membrane bioreactors have several applications

  • Fertilizer & solvent extractors

  • Iron & steel industries

  • Pharma industry

  • Petroleum refinery

  • Dye & chemicals unit

  • Pulp & paper industry

Summary

➙ MBR is the low-footprint, high-effluent-quality solution to your wastewater treatment needs. It can be used to upgrade existing WWTPs as well as to build new, state-of-the-art facilities.

➙ How does a membrane bioreactor work in wastewater treatment processes?

➙ The crucial function of membranes is to separate solids from a liquid. In activated sludge facilities, this is traditionally accomplished using secondary clarifiers.

➙ Two process configurations are possible:

➙ Submerged MBR, in case vacuum-driven membranes are used (like PCI HF-Zmbr2 Series)

➙ Sidestream (or external) MBR, in case pressure-driven membranes are used (like PCI A-Series).

➙ Usually, pressure-driven membranes are used for smaller installations and/or tough-to-treat industrial wastewaters, while submerged membranes are used for medium and large installations.
