Refined Cotton Wastewater Treatment with Decoloring Agent, PAC, and Anionic PAM

Refined Cotton Wastewater Treatment with Decoloring Agent, PAC, and Anionic PAM

Refined Cotton Wastewater Treatment: A Four-Step Jar Test

Case Summary

A Bluwat Chemicals laboratory jar test demonstrated a visible change in a dark refined cotton wastewater sample following a four-step treatment process: 300 ppm of decoloring agent → 2,000 ppm of PAC → alkali addition to adjust the pH to 7–8 → anionic PAM for flocculation.

The final sample showed a lighter upper liquid layer above a substantial layer of settled brown flocs. This visual result provides a starting point for further treatment evaluation using the customer’s wastewater.

Wastewater Sample and Test Objective

The sample was identified as wastewater from refined cotton production. The original wastewater appeared very dark, making a laboratory comparison useful for observing changes in liquid appearance and solids separation.

The test evaluated a treatment sequence combining a decoloring agent, polyaluminum chloride (PAC), pH adjustment, and anionic polyacrylamide (PAM). The purpose was to observe how the sample responded to the complete chemical treatment process.

Refined cotton wastewater four-step jar test using 300 ppm decoloring agent, 2,000 ppm PAC, pH adjustment to 7–8, and anionic PAM

Step 1: Add 300 ppm of Decoloring Agent

The first step was to add 300 ppm of decoloring agent to the wastewater sample.

This introduced the decolorization stage at the beginning of the treatment sequence. The dosage shown belongs to this particular jar test and should be evaluated again when the wastewater composition changes.

Step 2: Add 2,000 ppm of PAC

Next, 2,000 ppm of polyaluminum chloride (PAC) was added.

PAC served as the coagulant in the treatment process. In this demonstration, it was added after the decoloring agent and before pH adjustment.

Step 3: Adjust the pH to 7–8

Alkali was then added to bring the sample to a pH of 7–8.

This was a separate step in the recorded process. The amount of alkali was determined by the pH adjustment requirement; an alkali dosage was not provided in the demonstration.

Step 4: Add Anionic PAM for Flocculation

Finally, anionic PAM was added to promote flocculation.

The PAM dosage was not specified. The final treated sample contained visible flocs and a distinct separation between the upper liquid and the settled material.

Visual Treatment Result

The comparison showed two clear differences:

Before Treatment

The original wastewater appeared very dark.

After Treatment

The treated sample had a much lighter upper liquid layer, with brown flocs accumulated at the bottom of the beaker.

Some residual color remained in the upper liquid. The image therefore demonstrates an improvement in visual appearance and solids separation, rather than complete color removal.

No measured color, COD, or suspended solids results were supplied with this test. These parameters would need to be analyzed to quantify treatment performance.

What This Case Means for Refined Cotton Producers

This case offers a practical treatment sequence for initial laboratory evaluation. It does not establish a universal chemical recipe for every refined cotton production facility.

A useful next step is to repeat the jar test with representative wastewater samples, compare chemical dosages, and measure the treated water against the facility’s treatment objectives.

Discuss Your Wastewater Sample with Bluwat Chemicals

Bluwat Chemicals supplies decoloring agents, PAC, and polyacrylamide for industrial wastewater treatment.

If your refined cotton wastewater has a similar dark appearance, share your wastewater characteristics, current treatment process, and target water quality with our team. A sample-based evaluation can help identify suitable chemical grades and dosing conditions.
