Complexed copper and nickel
Electroless copper, surface-treatment and related segregated streams. Review total Cu/Ni, COD or TOC, reagent use, dry solids and continuous stability.
INDUSTRIAL WATER TREATMENT
Validate with real water.
Decide with operating evidence.
Nano-Fe heterogeneous complexation for selected PCB, rare-earth and electronic copper-foil wastewater streams, from sample screening to bypass pilot and engineering coordination.

PRIORITY STREAMS
Start with the stream
that changes the decision.
High-value metals should be recovered first. The platform is assessed for complexed or residual streams where polishing, stability or reuse risk remains.
Fluoride and multi-metal tailwater
Assess high-salt competition, fluoride, phosphorus, residual metals and rare-earth constituents after recovery steps.
Polishing before reuse
Focus on residual metals, turbidity or SDI, membrane impact, cleaning frequency and the treatment-cost basis.
TECHNOLOGY
Transfer contaminants
to a separable solid phase.
Active iron oxyhydroxide surfaces support heterogeneous complexation, adsorption and co-precipitation. Conditions must be confirmed against representative water.
- 01
Characterise
Map water source, speciation, coexisting ions and the current process.
- 02
Screen
Test capture, controlled oxidation where relevant, and solid-liquid separation.
- 03
Pilot
Run a matched bypass comparison and optimise operating parameters.
- 04
Define
Confirm the design envelope, acceptance basis and implementation boundary.
MODULE ARCHITECTURE
Make every process interface
visible before fabrication.
This functional diagram shows the review sequence, not the final project arrangement. Module size, materials and interfaces are confirmed against the design envelope.
- Sizing basis
- Flow range × operating hours × contaminant load
- Materials
- Confirmed against pH, salinity, oxidants and site conditions
- Controls
- pH, ORP, flow and turbidity; optional project-specific interfaces
- Handover
- P&ID/interface list, operating parameters and acceptance basis

7 + 30 + 90
Validation before
engineering commitment.
Indicative stages only. Timing depends on sample availability, site conditions and the continuous-run plan.
Sample diagnosis
Water analysis, bench screening, initial reagents and a pilot recommendation.
Bypass pilot
Matched influent comparison, stability, reagents, energy, solids and reuse impact.
Continuous demonstration
Operating variability, start-stop events, design envelope and commercial handover basis.
What we do not promise before validation
No fixed removal result, cost reduction or payback period is claimed without a representative-water test and agreed operating conditions. Cyanide-bearing, radioactive or other specialised streams require separate assessment and qualified implementation.
NEXT STEP
Prepare the pilot brief.
Organise water-quality data, the current process, cost baseline and site conditions before the first technical review.
