Client Profile

A leading food manufacturing company with a production facility in Dubai.

Challenge

The client was struggling to manage wastewater generated from their production processes, particularly from the CIP (Clean-in-Place) cycles.

Wastewater Characteristics

Preliminary analysis revealed that the effluent contained:

  • A high fraction of biodegradable organics
  • Significant levels of suspended solids
  • Noticeable amounts of emulsified oils

These factors made efficient treatment essential to ensure compliance with discharge standards and enable safe reuse options.

Solution

Tailored Treatment Design
Emvees designed a customized treatment system using Moving Bed Biofilm Reactor (MBBR) technology, incorporating all key stages of wastewater treatment: preliminary, primary, secondary, and tertiary.

Key Stages of Treatment

  • Preliminary Stage: Coarse and fine screens were installed to capture and remove large, suspended solids.
  • Primary Stage: A Dissolved Air Flotation (DAF) unit was introduced to remove residual suspended particles and emulsified oils, while also reducing organic load.
  • Secondary Stage: The MBBR reactors were engineered to achieve up to 95% removal of biodegradable organics, ensuring efficient biological treatment.
  • Tertiary Stage: A two-step filtration process, combining pressure sand filtration and activated carbon filtration, provided final polishing of the treated effluent.
  • Skilled Labor: Specialized technicians are required for UF operation and maintenance, adding to overall costs.

Results

  • The system consistently delivers effluent that complies with standards for restricted irrigation and landscaping use.
  • A large portion of the facility’s landscaping water demand is now fulfilled through treated wastewater, reducing dependence on external water sources.
  • Emvees’ operations and maintenance team has successfully managed the plant for over eight years, ensuring stable performance and compliance.
