Every unit is proven before it leaves our facility. Hydrostatic testing, weld inspection, surface finish verification, and performance validation against design specifications. Not inspected after delivery. Verified before dispatch.
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.
Quality assurance that eliminates commissioning surprises
The most expensive time to discover a fabrication defect is during commissioning at your site. Our quality assurance programme is designed to catch every issue before the unit leaves our facility. Weld defects, dimensional deviations, surface finish problems, and hydraulic performance shortfalls are all identified and corrected in our workshop, not at your plant. This is the difference between a smooth startup and a delayed project.
Every pressure-containing vessel is hydrotested to 1.5 times design pressure. Leak paths, weld porosity, and structural weaknesses are exposed under controlled test conditions, not during operation.
Visual inspection, dye penetrant, magnetic particle, and ultrasonic testing of critical welds. Weld maps are maintained for traceability, and procedures are qualified to ASME and EN standards.
CMM and manual measurement against engineering drawings. Critical dimensions including vessel diameter, nozzle positions, plate spacing, and flange alignments are verified before sign-off.
Tailored validation for each category of treatment equipment
Air dissolution efficiency, bubble size distribution, skimmer alignment, and flotation zone hydraulics are tested with water and simulated solids. Surface overflow rate and solids loading are verified against design values.
Plate spacing and angle verification, inlet distribution uniformity, sludge hopper drainage, and overflow weir levelness are all checked. Hydraulic loading is confirmed within design range.
Media depth and grading, underdrain distribution uniformity, backwash flow rate, and filtration rate are tested. Pressure drop across clean media is measured as a baseline for future comparison.
Aeration uniformity, mixer power draw, carrier retention, and DO distribution are tested. Bubble pattern and mixing intensity are verified to prevent dead zones and ensure complete biological contact.
Belt tracking, roller alignment, polymer dosing calibration, and cake dryness are tested with representative sludge. Belt tension and washwater pressure are set to manufacturer specifications.
Dosing pump calibration, mixing intensity, and reaction tank residence time are verified. Chemical compatibility with wetted components is confirmed through exposure testing.
This treatment stage is engineered to achieve specific contaminant removal targets while providing stable, predictable performance across variable inlet conditions. Design parameters are calculated from wastewater characterisation data, regulatory requirements, and site-specific constraints including footprint, energy availability, and operator capability.
Design validated by CFD modelling and pilot testing to confirm performance guarantees.
Equipment selected for 20-year design life with minimal wearing parts and easy access.
Automated dosing and feedback control minimise reagent consumption and sludge production.
Online monitoring and data logging demonstrate continuous consent compliance.

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.
