Mogden Sewage Treatment works is the second largest in Thames Water, treating a population equivalent of 1.8 Million. During 1998 Thames Water identified that the existing digester heating system was unable to maintain digester temperatures during cold periods and that the mixing systems
were suffering repeated failures. A radical increase in design loads to 4.2 KgVS/m3 (0.26 lbVS/ft3) has required a number of innovative heating and mixing systems. This paper details the key systems installed as part of the refurbishment program including 16 novel
sequential gas mixing systems and a total of 13,208 kW (45,065,596 BTU/hr) of heating capacity. The paper highlights the leverage of key process elements in a digester refurbishment program.
