Water Treatment Systems: Clarifiers, PSF, ACF, Softeners, UF, RO, EDI, UV, Mixed Bed Filters
Wastewater Systems: Equalization, Neutralization, Flash Mixers, Clarifiers, DAF, ASP, MBBR, MBR, SBR
Sludge & ZLD Systems: Sludge handling, UF, RO, Brine Concentrators, MEE, ATFD, Crystallizers
UPW Systems: Degasifiers, EDI, UV-TOC, Final Filters, Distribution Loops
Ensure operation within design and contractual limits
B. Process Monitoring & Performance Evaluation
Analyze flow parameters: feed, product, reject, recycle
Monitor key water quality parameters:
Physical: pH, turbidity, temperature, TSS, conductivity, resistivity, SDI
Chemical: TDS, hardness, alkalinity, chlorides, sulphates, silica, TOC, COD, BOD, etc.
Biological: MLSS, MLVSS, SVI, DO, F/M ratio, SRT, OUR, SOUR
Identify deviations and initiate corrective actions
C. Membrane Performance Monitoring
Track UF, RO, MBR, and EDI system performance (pressure, flux, recovery, rejection, permeability)
Identify fouling/scaling trends and recommend CIP schedules
D. Process Optimization

Chemical dosing (coagulants, antiscalants, acids, caustic, nutrients)
Energy usage (blowers, pumps, compressors, membranes)
Improve process parameters such as DO, sludge age, aeration, and flux
Drive reduction in chemical consumption, power usage, sludge generation, and OPEX
E. Laboratory Data Review
Validate lab results (COD, BOD, MLSS, SDI, conductivity, TOC, silica, etc.)
Recommend process corrections based on analytical data
F. Root Cause Analysis & Troubleshooting
Investigate system issues across RO, biological, ZLD, and UPW systems
Perform RCA, FMEA, CAPA implementation
Resolve issues like membrane fouling, sludge bulking, scaling, and process instability
G. Chemical & Mass Balance Calculations
Prepare water, mass, salt, sludge, and chemical balances
Evaluate system efficiencies (recovery, rejection, specific consumption)
Generate improvement recommendations
H. Performance Guarantee Monitoring
Track KPIs: plant uptime, water quality, recovery, chemical & energy consumption
Monitor SLA compliance and prepare deviation reports
I. Process Improvement Projects
Identify and implement improvements in recovery, reuse, and efficiency
Support debottlenecking, pilot trials, and technology upgrades
J. Process Documentation
Develop and maintain SOPs, OCPs, process flow diagrams, startup/shutdown procedures
Maintain process logs, trends, and performance reports
K. Client Coordination & Technical Support
Participate in review meetings and present technical insights
Coordinate with cross-functional teams (Operations, Lab, Mechanical, E&I, OEMs)
Deliver performance, RCA, and improvement reports
L. Safety, Environmental & Statutory Compliance
Ensure compliance with CPCB/SPCB norms, environmental regulations, and safety standards
Promote safe chemical handling and sustainable operations
