This study evaluated the performance of sand (ES: 0.17 mm, UC: 3.13) and crushed recycled glass (ES: 3.59 mm, UC: 4.18) in pilot-scale subsurface filters treating municipal wastewater. The system provided on-site treatment for secondary lagoon effluents from the Village of Dunnottar, on the southwest shore of Lake Winnipeg, MB. Filters operated at a 24-hour HRT, with active treatment seasons from May to September. System performance was assessed over a two-year period (2017 - 2018), with regards to total suspended solids (TSS), chemical oxygen demand (COD), nitrogen (N) and phosphorus (P). TSS were removed equally well in sand and glass filters, with removal efficiencies above 90%. Sand and glass filter effluents contained mostly dissolved COD, except within the first month of operation, during which both media failed to achieve local BOD guidelines. Dissolved COD removal was 29% less in glass, due to smaller media surface area. NH4+-N reductions exceeded 90% in both filters. Effluent N guidelines were always met by sand filters, whereas glass exceeded the limit 33% of the time in 2018. Both sand and glass failed to reduce P below 1 mg/L. Sand filters seemed to predominantly remove P through mineral precipitation with Ca and Mg compounds. This contributed to concretion (hardening) of top sand filter layers. P removal was significantly less in glass, due to decreased Ca availability within the media. Obtained results indicate that crushed recycled glass can be used as filter media in tertiary wastewater treatment systems, especially to remove TSS, COD and NH4+-N.

The purpose of this book is to introduce the phosphorus (P) removal structure as a new BMP for reducing dissolved P loading to surface waters from non-point source pollution, provide guidance on designing site-specific P removal structures, and provide instruction on use of the design software, “Phrog” (Phosphorus Removal Online Guidance). The book initially provides a review of the nature and sources of non-point source P pollution, examines short and long term solutions to the problem, and provides detailed theory on design and operation of the P removal structure. As with many areas of study, one of the best methods of communicating concepts is through illustrations and examples. This book is no exception; several years of experience in studying P sorption and constructing P removal structures at multiple scales and settings is utilized for providing real examples and applications. With an understanding of the P removal structure established, the reader is instructed on how to obtain all of the necessary inputs for properly designing a site-specific P removal structure for meeting a desired lifetime and performance, or predict the performance and lifetime of a previously constructed P removal structure. For the readers who already possess the Phrog design software or are interested in obtaining it, one chapter is dedicated to detailed use of the software as demonstrated with various examples of structure design and also prediction.

The past 30 years have seen the emergence of a growing desire worldwide that positive actions be taken to restore and protect the environment from the degrading effects of all forms of pollution – air, water, soil, and noise. Since pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unreal- tic demand for zero waste. However, as long as waste continues to exist, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been identi?ed: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers formulate answers to the last two questions above. The traditional approach of applying tried-and-true solutions to speci?c pollution p- blems has been a major contributing factor to the success of environmental engineering and has accounted in large measure for the establishment of a “methodology of pollution control. ” However, the realization of the ever-increasing complexity and interrelated nature of current environmental problems renders it imperative that intelligent planning of pollution abatement systems be undertaken.
