COAGULANT – POLYELECTROLYTE SYSTEM FOR THE CONDITIONING DIGESTED AND SONICATED SEWAGE SLUDGE
The article presents the results of research on the impact of inorganic coagulants and polyelectrolytes and their common action on sonicated digested sludge. Sonication of sludge samples was carried out under static conditions for 60, 120 and 180 seconds. The ultrasonic wave of f = 20 kHz and two di...
