Experimental feasibility study on application of a mechanical cavitation inducer for disintegration of wastewater sludges

Each construction modification was accompanied by batch test experiments used to check the physicochemical properties of the sludge water at different disintegration times (0-1280 seconds), which are proportionally related to energy inputs per sludge volume – Ev (kJ l−1). All tests started within 1 h after sampling to prevent subsequent sludge changes. The schematic diagram of the experimental set-up is shown in Figure 1.
