Selecting chemicals is only part of a wastewater treatment evaluation. A useful jar test also records the order of addition, the dosage of each product and the pH before the final flocculation stage.
This Bluwat Chemicals case examines the dosing sequence used for a shampoo wastewater sample. The procedure combined initial treatment with BWD-01 decoloring agent, PAC coagulation, adjustment to pH 7 and anionic PAM addition.
The case provides a documented starting point for further testing of the sample’s response to chemical treatment.
The laboratory evaluation addressed shampoo wastewater decolorization and floc formation.
The available experiment record identifies the wastewater type and chemical additions. It does not specify the customer’s location, production capacity, wastewater flow or initial pollutant concentrations. The discussion therefore focuses on the tested procedure.
BWD-01 decoloring agent was added first at 5,000 ppm.
Starting with this step allowed the decoloring agent to contact the wastewater before PAC was introduced. In a comparative study, documenting the sample after this addition would help assess its contribution to the overall treatment response.
PAC was added next at 1,000 ppm.
This was the coagulation stage of the procedure. Together, the first two additions formed the treatment conditions leading into pH adjustment and final flocculation.
The test record describes this specific order; it does not establish that the same sequence is optimal for every shampoo wastewater stream.
After adding decoloring agent and PAC, alkali was used to adjust the pH to 7.
Recording where pH adjustment occurs makes the procedure easier to reproduce. In this case, pH 7 refers to the wastewater condition after the first two chemical additions and before anionic PAM.
A repeat trial should use measured pH as the endpoint for alkali addition.
Anionic PAM was added last to promote floc formation.
Its dosage was not supplied, so the available procedure is not yet a complete dosing specification. A repeatable operating record would need to include the PAM dose, solution preparation details and mixing conditions.
Floc formation is one observation in a treatment assessment. Selecting conditions for plant use also requires evidence about the water and solids after separation.
A follow-up test should document:
These measurements would help determine whether the tested conditions should be retained or adjusted.
The recorded BWD-01 decoloring agent and PAC dosages provide reference points for a dosage comparison.
Further work should establish the anionic PAM dose and record consistent mixing and observation conditions. Trials using representative samples can then show whether treatment performance remains consistent as wastewater characteristics change.
Any plant trial should also consider the existing chemical dosing system and downstream solids separation equipment.
The central feature of this experiment is its documented sequence:
BWD-01 decoloring agent at 5,000 ppm → PAC at 1,000 ppm → alkali adjustment to pH 7 → anionic PAM for flocculation.
This sequence can guide further laboratory evaluation of the shampoo wastewater sample. Additional measurements are required to confirm removal efficiency, optimize chemical consumption and assess suitability for full-scale operation.
The pH was adjusted after adding BWD-01 decoloring agent and PAC, and before adding anionic PAM.
Yes. It was added at the final chemical dosing stage to promote floc formation.
No discharge compliance data were provided. Treated-water analysis against the applicable requirements would be needed.
