Umer Shahzad

• Operated and maintained the complete wastewater treatment system, including screening, equalization, primary treatment,
biological digestion, aeration, and sludge management.
• Managed both aerobic and hybrid anaerobic digesters, ensuring consistent biological performance and proper breakdown
of organic matter.
• Controlled the gas generation and storage system — biogas produced in the Hybrid Aerobic Digester was collected in a gas
holding tank, monitored for pressure, and safely burned in a flare to prevent methane release to the atmosphere.
• Oversaw the screening process to remove solid materials before biological treatment and maintained consistent inflow rates
to protect downstream units.
• Managed the equalization tank for flow balance and pH correction to maintain steady conditions for the digesters.
• Operated the aeration system with precise blower control to achieve desired DO levels and microbial efficiency.
• Conducted routine sampling and laboratory analysis (COD, pH, TSS, alkalinity) and adjusted process
parameters accordingly.
• Supervised sludge recirculation and dewatering operations using the screw press system for efficient solids removal.
• Operated SCADA and HMI systems, reviewed alarms, performance trends, and maintained daily data logs.
• Ensured safe chemical handling including polymer, NaOH, and nutrients according to safety procedures.
• Performed regular inspection of pumps, blowers, filters, and agitators, and coordinated preventive maintenance with the
mechanical team.
• Maintained daily log sheets and inspection records, ensuring complete documentation for plant operations.
• Arranged weekly coordination meetings with the Plant Manager to review system performance, troubleshoot issues,
and plan maintenance activities.
• Followed all safety and environmental regulations, ensuring efficient and compliant plant performance.

• Operated MBBR-based wastewater treatment plant, managing all stages from inlet screening to treated water discharge.
• Supervised the screening and grit removal process to protect pumps and downstream treatment units.
• Managed equalization tanks, balanced hydraulic loads, and ensured proper aeration.
• Controlled MBBRreactor performance, optimized biofilm growth, and maintained required DO and MLSS levels.
• Operated multimedia and cartridge filtration units for final polishing and water reuse.
• Conducted daily testing for COD, BOD, pH, TSS, and other key quality parameters.
• Operated SCADA-based control system, monitored alarms, and ensured continuous plant operation.
• Handled chemical dosing and polymer preparation for improved flocculation and sludge separation.
• Managed sludge drying beds, maintained proper dewatering and safe disposal procedures.
• Conducted routine inspection and maintenance of blowers, pumps, and filters to minimize downtime.
• Maintained daily logbooks and inspection reports, ensuring proper documentation of all plant activities.
