When H&M's auditor asks for batch traceability on your coagulant, what do you hand them?
Pakistan's top textile groups — Interloop, Sapphire, Nishat, Gul Ahmed — are all moving toward Zero Liquid Discharge by 2028, with H&M, Bestseller, Inditex, Levi's, and HIGG FEM 4.0 audits driving chemistry programme upgrades. AAS supplies PAC and CPAM for dyehouse clarification, UN-307 for RO antiscalant on tertiary RO trains, and AD-401/303 for any cooling loop in the mix. Sole Pakistan agent for Shaanxi Ande and Innovative Water.
ZLD-aware · Brand-audit-ready CoAs · Same-week Karachi dispatch
From January 2026 the dye-house is under EU scope. The audit fails on the CoA, not the chemistry.
EU Green Deal compliance now covers 500+ employee mills — Interloop, Nishat, Gul Ahmed, Sapphire are all over the threshold, and 68% of Pakistani textile exports go to the EU. Stack the brand audits (H&M, Bestseller, Inditex, GOTS, HIGG FEM 4.0) on top, and the regulatory load is structural. Faisalabad's 23 April depletion warning (310 MGD wastewater, 7% treated) makes provincial enforcement the next chapter. Most ZLD pre-treatment programmes here fail buyer audits on coagulant CoA traceability. AAS imports Shaanxi Ande PAC + CPAM with batch-traceable CoAs from Xi'an manufacture date through Karachi port to your tank — single-supplier line of custody, not a re-bagger.

Where AAS chemistry has run through textile water programmes.
Dyehouse ETP rebuild · Faisalabad · 2021
Designed and supplied a PAC + CPAM dosing skid for a dyeing facility's primary clarifier. ETP performance brought back into NEQS compliance; effluent COD ↓ 62%, sludge volume ↓ 35%. Same pattern as Interloop / Sapphire dyehouse work.
Tertiary RO antiscalant programme · 2023
UN-307 phosphonate dosing for a 200 m³/h tertiary RO train recycling dyehouse effluent toward ZLD. Chemistry tuned per-batch from feedwater silica + sulfate profile. Compliant with brand audit documentation requirements.
Cooling-tower chemistry for textile utilities · 2024
AD-401 + AD-303 programme on a 6,000 m³/h cooling loop serving a finishing plant. 14 months on programme; cycles of concentration sustained at 5.0+; brand audit passed first-pass.
Stocked SKUs, every drum with a CoA.
Sole-agent direct from two specialist Chinese principals (Shaanxi Ande, Innovative Water) — no trader mark-up, single legal entity at the Karachi office and the dosing skid. Per-batch certificate of analysis on every shipment. Engineering desk in Karachi for feedwater audits, programme design, commissioning, autopsy.
PAC — polyaluminium chloride, multiple Al₂O₃ basicities, liquid + powder CPAM — cationic polyacrylamide, multiple charge densities, powder + emulsion UN-307 / UN-611 — RO antiscalant + non-oxidising biocide for membrane systems AD-401 / AD-303 / AD-402 — cooling-tower antiscalant, corrosion inhibitor, recirculating-system fungicide
"Anyone can sell you a drum. We tell you how to dose it. That is the difference between a trader and a chemistry partner, and we are deliberately the second." Syed Rayhan Ahmad · Founder · Austin Anderson Solutions, Karachi
Capability statement, ready to share with the engineering team.
If your team is preparing the next utilities-chemistry tender, or you have a current scaling / fouling / foaming event that needs a chemist on the dosing skid this week, AAS can come to your site the same business day in Karachi. Capability statement PDF is below; ISO 9001 cert, NSF documentation where applicable, and sample CoAs shared on supplier-qualification request.
I'm with a Pakistani textile mill and want chemistry for ETP, ZLD, or cooling.
Tell us your site, the loop or train, the symptom, and the volume. Same-business-day reply from Karachi with a programme outline and the relevant CoAs / SDS attached.
