Investigating Flocculation Agents for Dow BV

CLOSED FOR APPLICATIONS - The Dow fresh water WWTP is suffering from poorly settling sludge, thereby limiting the plant's hydraulic treatment capacity. As the effluent quality is critical for reuse as cooling tower make-up, currently no chemical additives are applied to improve settling behavior of the activated sludge.

The objective of this study is to identify suitable coagulant/flocculation agents, which both improve settling properties and do not have a detrimental impact on the effluent quality. Lab testing using actual activated sludge and wastewater (by means of a jar-tester) is a key component of the task. Moreover the student is challenged to generate an effective cause-effect monitoring plan, comprising the characterization of incoming wastewater (by means of chemical or physical testing), determining activated sludge settling properties, and the suitability of coagulating/flocculating agents.
