Dear , for my business in Germany we are looking for a reliable supplier of Chitosan for liquid-solid-separation; especially sewage sludge and manure. We need the best product adapted to this need - at the lowest price (so purity is not that important).Can you help us with the product and pricing - and do you facilitate sample shipments? Best regards,Hartmut Schultzcolour:Off-white, or light yellow powder,Packaging:fiber drumCertification:QS/ ISO 9001 Show More
