An advanced rotary drum screen that separates solids from the wastewater stream — high-capacity inlet screening with low headloss and automatic cleaning.
Compact vertical spiral screens for space-constrained installations.
External rotary drum screens for channel installation. Continuous screening with external brush cleaning and integrated conveying.
Bar screens and screening sieves for mechanical solid separation.
Static curved screens for solid-liquid separation in wastewater.
An advanced device for separating solid elements from waste water stream. Flow is directed into a slotted drum. Water flows through the drum and solids are scrapped outside.
The rotary drum screen is engineered for continuous operation with minimal maintenance requirements. The drum rotates slowly, allowing water to pass through the slots while solids are carried to the top and discharged.
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.
