Quality Control for Water Decoloring Agent and Wastewater Treatment Chemicals
Hubei Haite supports overseas buyers with raw material checking, batch production control, laboratory testing, jar-test guidance, COA before shipment and document support for water decoloring agent, PAC, PAM and related chemicals.
How We Control Product Quality
For water treatment chemicals, buyers care about stable performance, repeatable dosage and clear documentation. This page explains the key quality-control steps before sample or bulk order.
Check incoming raw materials and storage status before production.
Monitor key production records and maintain batch traceability.
Check appearance, pH, solid content and other reference indicators.
Use jar test to evaluate color removal, floc size and settling.
Prepare COA, MSDS, TDS and packaging information on request.
Laboratory Testing and Jar-Test Support
The most important test for water decoloring agent buyers is not only a laboratory index. Buyers need to see whether the chemical works on their actual wastewater.
Basic Index
Appearance, pH value, solid content and viscosity reference can be checked for batch control.
Jar Test
Use real wastewater to confirm dosage, pH adjustment, adding order and PAC/PAM combination.
Technical Feedback
Buyers can send jar-test photos or videos for dosage adjustment discussion.
Product Quality Reference Items
Exact indicators should follow the latest TDS and batch COA. The following table summarizes key items buyers commonly request before order.
| Product | Key QC Reference | Buyer Evaluation Focus |
|---|---|---|
| Water Decoloring Agent | Appearance, solid content, pH, viscosity, application performance | Color removal effect, dosage, floc settling and compatibility with PAC/PAM |
| PAC | Appearance, alumina content, basicity, insoluble matter | Coagulation effect, turbidity reduction and sludge condition |
| PAM | Molecular weight/type, dissolution, viscosity and flocculation effect | Floc size, settling speed, sludge dewatering and dosage |
| PolyDADMAC | Appearance, solid content, viscosity and cationic performance | Charge neutralization, coagulation support and wastewater compatibility |
Batch Control and Traceability
Batch consistency is important for overseas buyers because wastewater treatment cost depends on stable dosage and repeatable performance.
Batch Records
Production and QC records support traceability for each shipment batch.
Sample Retention
Representative samples can be retained for quality follow-up when needed.
Before Shipment
COA and document preparation help importers complete technical and warehouse review.
Documents and Certificates
Quality trust is built by both testing process and document availability. Buyers can request product and shipment documents according to order stage.
Packaging Inspection Before Shipment
For export orders, packaging condition, label information and shipping documents are part of the quality-control process.
Packaging Options
25kg drums, 200/250kg drums and 1000kg IBC can be discussed according to product and order size.
Shipment Review
Check product name, batch, quantity, packaging and destination requirements before shipment.
Export Documents
Commercial invoice, packing list, MSDS and COA can be prepared as requested.
Quality & Application Verification
Jar-test comparison and sample evaluation help determine dosage, sequence and compatibility with PAC/PAM before site trial.
Jar Test Result
Clear before/after comparison for textile dyeing wastewater color removal.
Sample Testing
Lab evaluation helps support dosage and process recommendations.
Controlled Production
Production and QC workflow support consistent supply.
Laboratory QC & Sample Analysis
Quality control and wastewater sample analysis help confirm product suitability before trial dosing.
QC Laboratory
pH, viscosity and sample testing support consistent product quality.
Dosage Analysis
Sample data helps recommend decoloring agent, PAC and PAM combination.
Updated Lab, QC & Documentation Visuals
Professional jar test and document visuals support quality-control and technical-service trust.
Jar Test Verification
Color removal and flocculation effect can be checked with actual wastewater.
Technical Documents
TDS, MSDS, COA and quality document support for export inquiries.
Technical Support
Wastewater data review and dosage recommendation support.
