100 KLD MBBR Based Sewage Treatment Plant

– RD Mines, Dariba (Rajasthan)

Client: Hindustan Zinc Ltd
Location: RD Mines, Dariba, Rajasthan
Capacity: 100 KLD
Technology: MBBR (Civil Based STP)

Project Brief

Hindustan Zinc Ltd approached Soma Utilities. for the design and
execution of a 100 KLD Sewage Treatment Plant at their RD Mines facility
in Dariba, Rajasthan. The objective was to install a robust and reliable STP
capable of meeting CPCB discharge norms under varying site and load
conditions.


Challenges

1 Sewage generation from 4–5 different locations across the mine area
2 Level differences making complete gravity flow impractical
3 Requirement of a civil-based STP suitable for long-term industrial use
4 Need for automation and online monitoring

Our Solution

After a detailed site visit and technical evaluation, we proposed a civilconstructed MBBR-based STP with a combination of gravity flow and
pumping system.


Scope by Soma Utilities

1 Complete process design and engineering
2 Submission of detailed drawings and technical documentation
3 Supply, installation, testing & commissioning of STP
4 Performance stabilization and handover
5 Civil construction and sewage pipeline work were executed by the
client.

Key Features & Equipment

  • Mechanical Bar Screen
  • MBBR Biological Treatment System
  • Dissolved Oxygen (DO) Meter for Aeration Control
  • Ozonator for Final Disinfection
  • Automatic Motorized Valves (MPVs)
  • Online Monitoring System for Regulatory Compliance

Project Execution

The project was executed strictly as per the approved drawings and was completed within the committed timeline. Effective coordination with the client ensured smooth installation and successful commissioning of the system.


Performance Outcome

  • Treated water quality achieved in compliance with CPCB norms
  • Stable and consistent plant performance
  • Automated operation with minimal manual intervention
  • High level of client satisfaction

Conclusion

This project reflects Soma Utilities’ expertise in delivering customized, civil-based MBBR STP solutions for industrial and mining applications, ensuring regulatory compliance, operational reliability, and timely execution.
