Answer» Correct option is (a) Non return valve Easiest explanation: A non return valve is a valuable investment to prevent air being drawn into digester, which would destroy the activity of BACTERIA and provided a potentially explosive mixture INSIDE the drum. Larger PLANTS may NEED counterweights of some SORT to ensure that the explosive mixture inside the drum.
