Organically bound phosphorus originates from body and food waste and, upon biological decomposition of these solids, is converted to orthophosphates. Biological phosphate removal is a relatively new technology dating back to the late 1950s it wasn't until the 1970s that there were full-scale processes developed for...

They are designed to achieve a specific wastewater treatment goal. Aquatic plant systems can be divided into two categories Systems with floating aquatic plants such as water hyacinth, duckweed, Systems with submerged aquatic plants such as waterweed, water milfoil, and watercress The use of aquaculture as a means of treating wastewater involves both...
