CFD ServicesComplete piping and instrumentation diagrams for mechanical pre-treatment processes with bypass and redundancy.
P&ID ServicesContainerised pilot screens for on-site validation of aperture size, throughput, and capture efficiency.
Pilot TestingThis 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.
Packaged, containerised, skid-mounted and research-station families engineered for sites with no road, no grid, no operator and no local supply chain.
All five product families plus the engineering choices that span the catalogue — transport envelopes, off-grid power, satellite SCADA, swap-on-failure spares.
