Ahura Aqua specialises in industrial wastewater treatment for post-ETP treated water — working closely with manufacturing end users and turn-key OEM integrators alike.
We collect wastewater from utility equipment — cooling towers, boiler blowdowns and ETP-treated streams — and apply a multi-barrier physiochemical membrane train that recovers up to 95% for direct reuse in production.

Our Membrane Recovery Scope

95%
recovered as low-TDS water
Reused directly in production processes and utility feed — this membrane recovery train is our product scope.
5%
concentrated reject
Handed off downstream to MEE / MVR evaporation for ZLD — outside our membrane scope.
Stage Specifications
PRE-TRT
Pre-Treatment
1 – 250 m³/hr
- PSF eliminates suspended solids & turbidity from canal, river, ETP & STP waters.
- ACF reduces chlorine, odour, colour and COD / BOD.
- Softening (SFT) removes hardness ahead of the membrane train.
AUTO · Pressure-drop sensors, differential pressure switch & timed backwash.
CRITICAL
Ultra-filtration
1 – 100 m³/hr
- Ultimate reduction in TSS, turbidity, SDI, colloidal silica, pathogens, bacteria & viruses.
- Filters pre-treated water to 0.02 – 0.04 microns — critical for membrane filtration.
AUTO · Chemically-enhanced backwash with auto chemical dosing on infeed composition.
SELECTIVE
Nano-filtration
1 – 10 m³/hr
- Highly effective on high COD / BOD waters and di-valent elements.
- Larger pore size than RO allows selective recovery of certain elements.
AUTO · Self-actuating valves driven by a vast choice of on-line sensors.
MEMBRANE
Reverse Osmosis
1 – 50 m³/hr
- Produces low-TDS water for direct re-use in utilities and production.
- Three-pass configuration (RO-I / RO-II / RO-III) for deep TDS reduction & maximum recovery.
AUTO · Various on-line sensors with self-actuating valves.
