Abstract : A balance between process efficiency and structural integrity is the prime objective in designing a large scale fixed film reactor for wastewater treatment. Various criteria must be considered before the proper biological oxidation media can be selected to achieve an optimum design. This paper examines the criteria for selecting plastic media, its performance standards, and its properties, such as its modulus of elasticity at the maximum working temperatures it will withstand; the ability of the media to retain these properties when exposed to the deleterious effects of chemicals, physical impact, and ultraviolet light; and the media's ability to remain efficient as biota growth accumulates on its surfaces. Performance standards for determining the maximum load plastic biofilter modules can support are also discussed. These standards were developed to provide a media which has structural strength to remain functional for the life of the process.
