What is the difference between the HQ and MQ grades?
HQ grades are specified in more detail: total solids, residual acrylamide, insolubles, molecular weight, charge density, particle size, solution viscosity and recommended working concentration. MQ grades are specified on bulk density, pH and maximum use concentration. Both anionic and cationic types are available in each. Tell us your application and we will help you choose.
Should I choose an anionic or a cationic grade?
Anionic grades are typically used for coagulated and mineral-rich streams. Cationic grades are typically used where organic or biological solids need to be bound, such as sludge conditioning ahead of dewatering. A jar test on your own water or sludge confirms the choice.
What is the shelf life of Sunfloc?
24 months for all four grades, when stored sealed in the original unopened pack at 0 to 35 degrees Celsius, away from moisture and direct sunlight.
What pack sizes are available?
HQ grades (Anionic HQ and Cationic HQ) come in 25 kg bags. MQ grades (Anionic MQ and Cationic MQ) come in 10 kg bags. Please contact us for bulk quantities.
What is Sunfloc used for?
Sunfloc is used as a flocculant in municipal and industrial water treatment, ETP and STP clarification, sludge dewatering, paper and textile applications, and mineral processing.
Can I download the specification sheet and MSDS?
Yes. Each grade has its own specification sheet and MSDS on its product page and on the quality and documents page.
