Description: As provincial regulations become stricter on the effluent water quality of wastewater lagoon treatment systems, cost efficient and low maintenance alternatives need to be developed for small rural communities. Gravity filters can be used to improve water quality of lagoon wastewater effluent. Previous studies have shown that recycled glass can be a cheap and viable alternative to the traditional sand filter bed used in the gravity filter system. In this research, recycled glass was compared to sand under filter start-up conditions through physical and wastewater quality analysis. In the physical analysis, the glass and sand were compared for particle size distribution, durability and permeability. In the wastewater quality analysis, water samples from recycled glass and sand filter beds were compared for reduction efficiency of ammonium, orthophosphate, nitrite, nitrate, chemical oxygen demand (COD), total phosphorus (TP) and total suspended solids (TSS). It was observed that recycled glass became less permeable as heterogeneous particles packed the filter bed over time. The glass was found to be more durable than the sand. The wastewater analysis showed that sand significantly reduced concentrations of orthophosphate, COD and TP in comparison to the recycled glass filter bed. Both filter beds produced similar reductions in TSS. The sand and glass filter beds were both shown to reduce concentrations of phosphorus below Manitoba Water Quality Standards effluent phosphorus requirements of 1mg/L. Under start-up conditions, glass could be used as a viable alternative to sand for wastewater filtration as it was able to reduce phosphorus below MWQS values.
