Reducing freshwater consumption and discharge volumes through water reuse
Water reuse is no longer an environmental aspiration; it is a commercial necessity. Rising freshwater requirements, increasingly stringent discharge permits, and corporate sustainability commitments are driving industries to recover and recycle process water. Reynolds & Bauhm designs integrated reuse systems that treat effluent to the quality required for cooling tower makeup, boiler feed, process washing, irrigation, and even product-contact applications.
Ultrafiltration and microfiltration provide an absolute barrier against suspended solids, bacteria, and colloidal matter, producing consistent filtrate quality regardless of upstream process variation.
Pre-treatment systems designed specifically to protect reverse osmosis membranes from fouling, scaling, and chemical damage. Proper protection extends membrane life and maintains permeate quality.
Closed-loop and partial-recycle systems that return treated water to process applications. Custom-designed for each industry's water quality requirements and operational constraints.
UF, MF, and integrated membrane bioreactors for water reuse
UF membranes with pore sizes from 0.01 to 0.1 micron remove suspended solids, bacteria, colloids, and macromolecules. Ideal for producing consistent filtrate for RO feed or direct non-potable reuse applications.
View UltrafiltrationMF membranes with 0.1 to 10 micron pores provide an absolute barrier for suspended solids and bacteria in a lower-pressure, lower-cost configuration. Excellent for tertiary filtration and polishing duties.
View MicrofiltrationMBR systems combine biological treatment with membrane filtration in a single integrated process. Produce very high-quality effluent suitable for direct reuse or as RO feed without separate clarification and filtration stages.
View MBR SystemsDisc tube reverse osmosis systems for challenging feed waters with high fouling potential. Open channel design tolerates high suspended solids and organics, making them ideal for landfill leachate and industrial effluent concentration.
View Disc Tube ROConventional spiral wound reverse osmosis for high-purity water production from pre-treated effluent. Multiple membrane grades available for brackish water, seawater, and industrial process water applications.
View Spiral Wound ROElectrocoagulation pre-treatment for membrane protection. Removes oil, suspended solids, and dissolved metals through in-situ coagulant generation, reducing membrane fouling and extending cleaning intervals.
View ElectrocoagulationIndustry-specific water recovery and recycling solutions
Tertiary-treated effluent polished through membrane filtration provides reliable cooling tower makeup water. Reduces freshwater consumption, blowdown volume, and chemical treatment costs in industrial cooling systems.
View Cooling TowerHigh-purity water for steam generation through multi-stage treatment including RO, ion exchange, and degassing. Protects boilers from scaling, corrosion, and carryover while reducing freshwater and chemical requirements.
View Boiler FeedRecycled water for vehicle wash, parts washing, and process rinse applications. Removes suspended solids and oil to prevent streaking, spotting, and contamination of washed surfaces.
View Wash WaterBiologically treated and disinfected effluent suitable for agricultural irrigation, golf course watering, and landscape irrigation. Nutrient content in treated water provides fertiliser value to crops and turf.
View IrrigationComprehensive pre-treatment trains protecting RO membranes from fouling and scaling. DAF, filtration, and chemical conditioning ensure sustained membrane performance and extended element life.
View RO Pre-TreatmentProduced water treatment for reinjection, discharge, or reuse in upstream oil and gas operations. Remove oil, suspended solids, and dissolved organics to meet environmental and operational requirements.
View Produced WaterThis 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.

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.
Speak with our process engineers to evaluate your effluent quality, identify reuse opportunities, and design a water recovery system that reduces costs and environmental impact.
Our expertise spans multiple industries with sector-specific water treatment solutions.
