Dear All, thank you very much for your comments. The tests were done and chemical staff has been chosen.  Aluminum sulphate and low anionic polyelectrolyte based on acrylamide and sodium acrylate are being used in a process of wastewater treatment. The results of the treatment are satisfactory. Currently we are looking for the best solution to improve dewatering of sludge produced in the wastewater treatment. I consider implementing of drying to obtain 85-90% of dry solid content and so I am looking for the adequate technology and equipment. Regards from Poland
