Water reuse & ZLD
Closed-loop systems that return treated effluent to process, cooling and irrigation, up to zero liquid discharge.
Overview
Reuse turns a disposal cost into a supply. We map every stream on site, then design the treatment that brings each one to the quality its next use needs. That ranges from simple polishing for irrigation to full ZLD with brine concentration and crystallisation.

500–40,000 m³/d*
ZLD option
Brine concentrator + crystalliser

How it works
The treatment train.
Each stage is sized on your water, not a catalogue. The sequence below is typical; every design is confirmed by sampling and, where useful, pilot trials.
01
Stream audit
02
Biological treatment
03
Ultrafiltration
04
RO polishing
05
Reuse & brine management



Why AQUARC
What you get that a catalogue doesn’t.
01
Supply security
Reused water is independent of drought restrictions and municipal price rises.
02
Discharge compliance
Less effluent leaving site means fewer permit limits to manage.
03
Fit-for-purpose quality
Each stream is treated to the quality its next use needs, never further.
04
Measured return
Every reuse design includes a lifecycle cost model you can audit.
