Methodology for developing process flow diagrams, mass balances, and optimising water treatment processes
CFD, P&ID, SCADA and commissioning for critical water treatment plants.
Plant layouts, piping isometrics and construction-ready engineering drawings.
Flow, mixing and thermal CFD across treatment and process equipment.
Full mechanical, physico-chemical, biological and sludge equipment range.
Behind the design sits a full modelling toolkit — CFD, process simulation, biokinetic (ASM/ADM), reaction-kinetics, hydraulic, limnological and data-driven digital-twin modelling. We pick, or combine, the disciplines that answer your question and validate them against real data.
Explore Scientific ModellingProcess flow design is the foundation of every successful water treatment project. It involves defining the treatment ob
Laser scanning, utility mapping, and soil investigation inform the design. We account for existing infrastructure, access constraints, and future expansion needs.
Mass balance, hydraulic, and process models size equipment correctly for peak, average, and minimum flow conditions. Over-design wastes Capital expenditure; under-design fails.
Revit and SolidWorks models show exactly how equipment fits in the available space. Clash detection resolves pipework conflicts before steel is cut.
Hazard and operability studies identify process safety risks, environmental releases, and equipment failure scenarios. Mitigation measures are designed in from the outset.
Independent chartered engineers review calculations, drawings, and specifications. Third-party verification adds confidence for boards, lenders, and insurers.
Constructability reviews during design identify operational benefits and programme efficiencies. Early contractor involvement prevents expensive surprises during installation.
Systematic Approach to Treatment Process Development
Establish clear water quality targets based on influent characteristics, regulatory requirements, and end-use specifications. Document flow rates, peak loads, and any special requirements.
Comprehensive analysis of raw water or wastewater quality including physical, chemical, and biological parameters. Identify seasonal variations and upset conditions.
Identify appropriate treatment technologies for each contaminant of concern. Consider proven performance, footprint, energy requirements, and operational complexity.
Arrange unit processes in logical sequence considering pretreatment requirements, chemical compatibility, and process interdependencies.
Calculate flows, concentrations, and loads at each process step. Verify hydraulic and contaminant balances throughout the system.
Size each unit process based on design flows, loading rates, and performance requirements. Include safety factors and future capacity.
Common Process Configurations
Raw Water → Coagulation → Flocculation → Sedimentation → Filtration → Disinfection → Distribution
Screening → Grit Removal → Primary Clarification → Biological Treatment → Secondary Clarification → Disinfection
Equalization → pH Adjustment → Coagulation/Flocculation → DAF → Biological Treatment → Polishing
Screening → Coagulation → Multimedia Filtration → Cartridge Filtration → RO → Post-treatment
