Overview of Sewage Treatment in International City Dubai
International City, one of Dubai’s distinctive residential communities, houses sophisticated sewage treatment infrastructure that serves its diverse population. The sewage treatment plant in International City Dubai employs a multi-stage process to transform wastewater into environmentally safe water that can be reused for various non-potable applications.
The treatment process involves three main stages:
Primary Treatment (Mechanical): Wastewater first passes through screens and grit chambers that remove large solid materials. This is followed by primary sedimentation tanks where heavier particles settle to the bottom as primary sludge.
Secondary Treatment (Biological): The partially treated wastewater then undergoes biological treatment where microorganisms break down organic matter. This stage often employs technologies such as Moving Bed Bio-Reactor (MBBR) or Membrane Bio Reactors (MBR), which have become increasingly popular in Dubai’s treatment facilities.
Tertiary Treatment (Chemical): The final stage involves disinfection, typically using chlorination or UV treatment, to eliminate remaining pathogens. Additional filtration may also be applied to further improve water quality before discharge or reuse.
