Explore our research on microbubble hydrodynamics, DAF physics, process Optimisation and emerging wastewater treatment.
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 ModellingEliminating uncertainty through experimental validation
The difference between equipment that meets specifications and equipment that exceeds them is verification. Our in-house R&D laboratory runs treatability studies, pilot trials, and analytical programmes on your actual effluent before we commit to fabrication. This eliminates design risk, validates performance predictions, and ensures that the equipment we build performs exactly as engineered.
Systematic evaluation of coagulation, flocculation, biological degradation, and advanced oxidation on your specific effluent. Chemical dosing, reaction times, and removal efficiencies are quantified with analytical rigour.
Full in-house analytical capability including COD, BOD, TSS, heavy metals, oil & grease, nutrient analysis, and microbiological testing. No waiting for external laboratory turnaround.
Rapid chemical optimisation through controlled jar tests. Polymer selection, coagulant dose, pH range, and mixing intensity are all determined through systematic bench-scale experimentation.
Full-scale performance prediction through scaled testing
Portable dissolved air flotation pilot rig with adjustable air dissolution, recycle rate, and chemical dosing. Test flocculation, flotation, and skimming performance on your actual wastewater before full-scale build.

No treatment stage operates in isolation. This process is designed to receive conditioned influent from upstream stages and deliver effluent quality suitable for downstream processes. Hydraulic and organic loading rates are balanced across the complete treatment train to prevent bottlenecking and ensure overall plant efficiency. Our engineers model the complete flowsheet to optimise Capital expenditure and Operating expenditure across the plant lifecycle.
Screening, equalisation, and pre-treatment protect this stage from damage and overload.
Effluent quality ensures downstream biology, filtration, or disinfection performs optimally.
Reject streams, filtrate, and centrate are routed back to appropriate upstream points.
Equipment specified for operational temperatures from -20°C to +60°C with appropriate insulation and heating options.
Material selection based on detailed water chemistry analysis. Cathodic protection and coating options for aggressive duties.
Equipment designed for 380-415V 50Hz, 460-480V 60Hz, and generator-backed installations for remote sites.
Compact vertical layouts, containerised skids, and modular expansion options for space-restricted installations.
Reduce project risk by testing your treatment concept on real effluent in our R&D laboratory. Pilot testing provides the data confidence that transforms engineering assumptions into proven performance.
Our expertise spans multiple industries with sector-specific water treatment solutions.
