the c650 worked best for septic waste dewatering. we sampled c640, c650, and c660. the c640 required 23% more polymer, c650 was same as our best usa polymer, and c660 was more efficient with 20% less but water quality and ability to drain thru filter belt was compromised. we are waiting on the tarriff war to be over so we can order.
Response from supplier:
First ,thank you for giving us another chance to send the samples again, and also for the detailed and honest feedback, we are waiting for doing business with you.
