In pellet flocculation blanket (PFB) process, pellet flocs' settling velocity is an important parameter, hence, it is necessary to investigate it to achieve optimum operation conditions of the process. To evaluate pellets settling behavior under different operational conditions, a dynamic experiment was carried out to concentrate ferric flocs sludge by PFB process with the scale of 0.5~1.2 m3/h. Under...
In this paper we propose an algorithm of computing minimal diagnosis based on BDD (Binary Decision Diagram). First we give the concept of disjunction equations, and map the collection of conflict sets into disjunction equations, then we compile the system into a BDD, further we compute the minimal hitting sets by solving the BDD and minimizing hitting sets. The reliability and completeness of the...
