The saturator is a critical component of Dissolved Air Flotation (DAF) systems, responsible for dissolving air into water under pressure. Our saturators utilise high-efficiency Pall ring packing to maximise the air-water contact surface area, ensuring optimal air dissolution for superior flotation performance.
Pall rings are a type of random packing media with an open structure that provides excellent gas-liquid contact while maintaining low pressure drop. The unique design allows for efficient mass transfer, resulting in higher air dissolution rates compared to conventional packing materials.
Our saturators are engineered for reliable, continuous operation with minimal maintenance requirements. The stainless steel construction ensures durability and corrosion resistance in demanding water treatment environments.
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.
