In this case, BWD-01 dosage should be adjusted in the test, and in the bulk test, we can dilute it with water as 1:10 or 1:20. The PAC, suggested to diluted to 5% Al2O3 content.
After dosing BWD-01 and PAC, suggested to adjust the pH to 7-7.5 for better flocculation, when in bulk test, we suggest to adjust the pH before dosing the chemicals, at least, ensure the pH7-7.5 after dosing the BWD-01 and PAC.
The PAM, we suggest to try Anionic, Cationic and Nonionic different types to choose a best one, in different cases, they are working different performance.
And we suggest to use frame filter or screw filter for sludge dewatering.
