Applications in Textile Dyeing Wastewater Treatment

Cr⁶⁺ reduction: 3Fe²⁺ + Cr⁶⁺ → 3Fe³⁺ + Cr³⁺. Dose 180–220 mg/L, pH 8.5–9.0. Result: Cr⁶⁺ 120 → <0.05 mg/L.

Coagulation of suspended solids and phosphate: Fe²⁺ oxidizes to Fe³⁺, forming Fe(OH)₃ floc.

Fenton AOP: Fe²⁺ + H₂O₂ → OH•. COD reduction of 60-85%.

Compare FeCl₂ and FeCl₃ as coagulants — COD and color removal performance.

Anonymized Case Studies

Technical Example 1 — 2,500 m³/day Textile Dyeing Wastewater System: COD 1,800 → 520 mg/L (72% reduction), color 1,200 → 80 Pt-Co (93% reduction). Fenton process, FeCl₂+H₂O₂.

Case 2 — Electroplating plant, 50 m³/day, Tan Binh Industrial Park: Cr⁶⁺ 2.5 → <0.05 ppm. FeCl₂ dose 80 mg/L, pH 2.2.

Actual industrial field deployment, automated dosing skid, and bulk warehousing operated by Loc Thien Chemical across Vietnam.

1. Incoming Batch COA Verification & Regulatory Compliance (Law on Chemicals 69/2025/QH15)

When operating industrial water treatment, surface finishing, or textile dyeing lines in Vietnam, engineering teams must verify every chemical delivery against its batch-specific Certificate of Analysis (COA) and 16-section GHS Safety Data Sheet (SDS). Under the Vietnam Law on Chemicals No. 69/2025/QH15, Decrees 24/2026/ND-CP, 25/2026/ND-CP, and 26/2026/ND-CP, and QCVN 40:2025/BTNMT on industrial wastewater discharge:

  • Specific Gravity & Assay Verification: Upon arrival of a 5–30-ton tanker or IBC tote shipment, plant QA technicians measure specific gravity at 20 °C using a calibrated hydrometer and cross-check active concentration against the batch COA issued by Loc Thien Chemical and verified via Quatest 3 (ISO/IEC 17025).
  • Impurity & Heavy Metal Control: Trace heavy metals (Fe, Pb, As, Hg, Cd, Cr⁶⁺) and insoluble matter are strictly controlled to prevent catalyst poisoning in Fenton reactors, membrane fouling in RO/UF systems, or shade deviations in reactive textile dyeing.
  • ZDHC MRSL v3.1 Level 1 Portfolio Boundary: For export-oriented textile and footwear FDI factories, Loc Thien Chemical maintains official ZDHC MRSL v3.1 Conformance Level 1 documentation for exactly 9 core products: four products certified by TUV SUD Product Service GmbH (NaOH, H2O2, Na2SO4, Na2CO3) and five products verified via Conformance Summary Report (CSR) and Analytical Test Report by TUV Rheinland Vietnam (H2SO4, FeCl2, HCl, Javel/NaOCl, PAC 31%).

Storage Safety AuditHDPE/FRP tank vents, secondary containment dike (110% volume), eyewashOSHA / Vietnam EHSZero vapor leak, immediate emergency readiness

2. Dosing Optimization, Storage Materials & Preventive Maintenance

  1. Compatible Wetted Materials: Use cross-linked high-density polyethylene (XLPE / HDPE), polypropylene (PP-H), fiberglass-reinforced plastic (FRP with vinyl ester resin), or PTFE/PVDF-lined piping depending on corrosive and thermal conditions. Avoid unlined carbon steel or incompatible elastomers.
  2. Automated Dosing Control: Integrate diaphragm metering pumps with real-time pH, ORP (mV), turbidity, or conductivity sensors. Always perform a 5-beaker Jar Test whenever raw water COD, TSS, or alkalinity shifts by more than 15%.
  3. Secondary Containment & PPE: Storage tanks must sit inside an acid/alkali-resistant bund wall holding at least 110% of the largest tank volume. Operators handling unloading hoses must wear splash-proof chemical goggles, acid/alkali-resistant nitrile or neoprene gloves, face shields, and emergency respirators.

3. Multi-Role B2B Value Matrix (Procurement · QA/EHS Engineer · Plant Director)

  • For Procurement Managers: Loc Thien Chemical is the direct manufacturer of FeCl2 30% solution and FeCl3 38–40% wastewater grade (3,000+ tons/month capacity), and a Tier-1 bulk commercial supplier of NaOH, HCl, H2SO4, PAC, NaOCl, H2O2, FeSO4, and Na2SiO3. Pricing is transparently structured around 5 technical cost drivers (active assay, packaging format, delivery distance from our 6 warehouses, order volume, and scheduled contract cadence) with a 15-minute technical quotation SLA.
  • For Environmental & Process Engineers: Full technical support for Jar Test optimization, stoichiometry calculation, sludge minimization, and QCVN 40:2025/BTNMT compliance auditing.
  • For FDI Plant Directors: Guaranteed supply continuity via 6 regional warehouses (Ba Ria - Vung Tau, Dong Nai, Binh Duong, Da Nang, Can Tho, Bac Ninh) and a dedicated 5–30-ton tanker fleet (4 hours in inner HCMC, 24–48 hours across Southern & Mekong Industrial Parks, 2–3 days in Northern & Central Vietnam).

Extended Engineering Calculation Example & Jar Test Protocol for FeCl2 30% Direct Production — ZDHC Test Report, Textile Dyeing Wastewater Treatment | Loc Thien

In a representative industrial wastewater treatment or surface treatment facility operating at a design flow of 1,200 m³/day (Technical Illustrative Example), process engineers evaluate dosing stoichiometry across three operating scenarios: baseline load, peak shift load (+25% COD/TSS), and seasonal rain dilution. Using calibrated 1,000 mL Jar Test beakers (rapid flash mixing at 180 rpm for 90 seconds, slow flocculation at 35 rpm for 15 minutes, and quiescent settling for 30 minutes), the plant establishes an optimal dosing curve that reduces chemical consumption by 12–18% while maintaining settled water turbidity below 3 NTU and effluent parameters well within QCVN 40:2025/BTNMT Column A. Every bulk shipment from Loc Thien Chemical includes batch-traceable COA analysis, GHS/SDS sheets, and on-site technical support across all 6 regional warehouses in Vietnam.

Transparent 5-Factor B2B Cost Structure & Supply Chain Optimization in Vietnam

Under Loc Thien Chemical’s transparent B2B commercial policy, unit chemical pricing is never published as a static retail figure online; instead, every formal quotation is engineered within 15 minutes around five verifiable cost drivers:

  1. Active Assay & Grade Specification: Concentration levels (such as 32% / 45% / 50% liquid NaOH vs. 99% pearls, or industrial vs. ZDHC-compliant grades) directly determine the active molar equivalent delivered per metric ton.
  2. Packaging & Bulk Delivery Mode: Bulk delivery via dedicated 5–30-ton corrosion-resistant tankers eliminates drum handling and minimizes per-ton logistics cost; 1,000 L IBC totes, 200 L drums, and 25 kg woven bags are also stocked.
  3. Dispatch Distance from Our 6 Regional Warehouses: Orders are routed from the nearest hub (Ba Ria - Vung Tau, Dong Nai, Binh Duong, Da Nang, Can Tho, or Bac Ninh) to cut freight lead time and carbon footprint.
  4. Order Volume & Annual Blanket Contracts: Scheduled monthly call-off contracts lock in priority safety stock and volume-tiered commercial terms, insulating factories from raw material spot volatility.
  5. Batch Documentation & FDI Compliance Package: Every delivery includes a batch-specific COA, 16-section GHS SDS, and—for our 9 certified core textile/footwear chemicals—official ZDHC MRSL v3.1 Conformance Level 1 documentation.
