Description

This report describes the development and testing of a new material for use as a filter medium in recirculating aquaculture systems and other water quality control situations. The material consists of a combination of activated carbon and a hydrophilic urethane foam in a homogeneous matrix. Its physical properties relevant to filtration were determined. It was then tested for its ability to remove various dissolved organic compounds and inorganic nitrogenous compounds in the form of a synthetic waste-water containing ammonia and nitrite. Finally it was subjected to long-term use in the biofilter of a fish culture system. It proved to be a successful filter medium for several applications and showed great potential for use in biofilters installed in recirculating aquaculture systems and other fish and shellfish culture facilities.
