Textile Wastewater PAC + PAM Coagulation & Flocculation Jar Test
This Short shows a PAC-and-PAM sequence in a textile wastewater jar test. It is a starting point for organizing a representative coagulation-flocculation screen, not a universal treatment recipe. Identify the sample point, fiber and dye context where known, pH, temperature, color or solids measurements, salt and surfactant conditions, and the planned separator. Compare an untreated control, PAC-only conditions and PAC followed by candidate PAM grades using consistent mixing and settling. Repeat the preferred condition on fresh representative samples before setting a plant trial, technical specification or purchase request.
Direct answer
This Short shows PAC and PAM added in sequence to a textile-wastewater jar test. Use it to structure a comparison on representative dyeing effluent: include an untreated control, record sample source and water conditions, keep mixing and settling conditions consistent, then repeat the preferred result before a controlled plant trial. Select the dosage from the documented screen and its measured treatment target.
What the textile jar-test video shows
The video title identifies a textile wastewater PAC and PAM coagulation-flocculation jar test. PAC is the first chemical family in the sequence; PAM follows to help build larger flocs for the downstream separation step. The visible test is useful for explaining the order to screen, but it is not a finished textile-treatment design.
Textile wastewater changes with fiber, dye class, salt, surfactants, washing steps and equalization. Keep the sample point and production condition with the result so a visually clear beaker is not treated as evidence for every stream.
Build the comparison around the actual effluent
Collect a representative sample and record whether it is segregated dye water, a combined stream or equalized effluent. Include pH, temperature, color method, suspended solids and known salt or surfactant conditions where available. Compare an untreated control, PAC-only conditions and PAC followed by candidate PAM grades under the same mixing and separation procedure.
Use the linked PAC and PAM product records to request current technical and safety documents for the exact grades screened.
Move from a beaker to a bounded plant trial
Before scale-up, repeat the preferred condition with fresh representative samples and document the exact product grades, batch identifiers, sequence, measured dose, mixing and separation observations. Agree the plant-trial objective and stop conditions with the operating team. At plant scale, hydraulic mixing, feed point, sludge separation and wastewater variability can change the response.
Use the trial record to decide whether to continue screening, adjust the product sequence or prepare an order-specific specification and quote. It should not convert a single visual result into a performance guarantee.

| Condition | Why include it | Record |
|---|---|---|
| Untreated control | Shows starting sample condition | Sample source and measurements |

Textile PAC/PAM screening flow
What should a textile plant send before a PAC/PAM recommendation?
The video provides a screening sequence; the application brief makes the screening relevant to the actual wastewater.
- Sample point and whether it is segregated, combined or equalized
- Fiber, dye and production context where known
- pH, temperature, color, solids, salt and surfactants where available
- Existing chemicals, separation equipment and measured target
- Requested product documents, package, quantity and destination
Buyer questions
What does the PAC + PAM textile wastewater video show?
It shows a PAC-and-PAM jar-test sequence for textile wastewater screening. The final product choice depends on representative water and measured trial conditions.
Why should PAC be screened before PAM?
The video uses PAC first and PAM after it. Compare that sequence with controls on the actual wastewater before setting a plant feed order.
Which textile-wastewater data should be supplied for a jar test?
Provide the sample point, fiber and dye context where known, pH, temperature, color or solids data, salt or surfactant information, and the planned separation equipment.
How should a textile team establish PAC or PAM dose?
Set the dose from a controlled screen that records the exact grade, sample, mixing, separation method and measured target.
How can a textile plant request product documents or a quote?
Send the wastewater application brief, preferred product families, package and quantity requirements, destination, and required specification, COA or SDS documents.
