Back in 2004 (Paper Technology, Vol.45, No.5, pp.39-41) Matt Smyth, then Senior Process Scientist, now Technical Director at
Aqua Enviro (part of Suez Water Technologies & Solutions), wrote an article that highlighted some of the common operational problems that faced effluent treatment plants in the paper and board industry; how to investigate them; and potential solutions. Fourteen years on, Matt reflects on what has and what may change considering BREF (Best Available Techniques Reference Document), generating revenue from wastewater via anaerobic digestion and driving down energy consumption whilst minimising the likelihood of filamentous bulking problems in the activated sludge plant.
