The effectiveness of two different biomaterials, i.e. Aloe Vera and Acorn leaves, has been tested in treating a real industrial petroleum wastewater through a coagulation-flocculation-sedimentation process. Experimental activities were aimed at evaluating the optimal operating conditions, in...

In an Anaerobic Digestion (AD) process treating particulate substrates, the size of solids is expected to negatively affect the rate of hydrolysis step and consequently influence the performance of the whole process. To avoid any disadvantage due to size of solids, expensive pre-treatments aimed...

This paper reviews pretreatment techniques to enhance the anaerobic digestion of organic solid waste, including mechanical, thermal, chemical and biological methods. The effects of various pretreatment methods are discussed independently and in combination. Pretreatment methods are compared in...
