Constructed Wetlands: A Solution to Treating Milking Centre Washwaters
No Thumbnail Available
As of 2016, all dairy farmers are required to properly treat their milk house wastewater prior to disposal. Dairy farmers are interested in a low cost and effective treatment technology to apply. The objective of this presentation is to outline the design, construction and analysis of a Horizontal Subsurface Flow Constructed Wetland (HSSFCW) technology coupled with the use of a passive phosphorus (P) filter to treat milking centre wash waters and/or barnyard runoff in three different sites in Canada. A HSSFCW technology can enable farms to divert wash waters from liquid manure storages, with potential wastewater re-use. The passive P filter, can help remove the high levels of phosphate in the wash waters.
