City and Industrial Development Corporation of Maharashtra (CIDCO) awarded HDO the job to construct a 25 MLD Sewage Treatment Plant at Khargar, Navi Mumbai.

For the first time HDO utilized “C-Tech”, an advanced Cyclic Activated Sludge process / Sequential Batch Reactor (SBR) for biological treatment of the sewage. Apart from biological treatment, the project also included:

• Pre-treatment using Screens and Grit removal units
• Sludge Handling System comprising of Centrifuges
• Chemical Dosing System

Also, the entire plant is automated (PLC based) requiring minimum manual intervention.

The plant was successfully commissioned and handed over to CIDCO in October 2008 and is running successfully since then meeting the discharge standards. HDO is currently operating and maintaining this plant for CIDCO.

Accomplishments:

• Successfully completed HDO’s first Sequential Batch Reactor (SBR) sewage water treatment project.
• Quality of treated effluent much superior to what can be achieved from conventional sewage treatment plants
• Client was very satisfied with the quality of work done for this project and recently awarded HDO with a second bigger order for a 70 MLD sewage treatment plant using the same SBR technology
