Different Sewage Sludge Treatment Methods

Various sewage sludge treatment methods are cost-effective solutions to enriching agricultural lands. Organic matter known as biosolids that are recovered from wastewater and sewage sludge are rich in nitrogen and phosphorus, as well as other valuable micronutrients. However, to ensure safety and viability of biosolids, they must first undergo various sewage sludge treatment methods. There…

Upcycling Nitrogen to Convert Sewage Sludge to Animal Feed

Nitrogen exists in many forms in the environment and can enter aquatic systems from fertilizer run-off and wastewater discharges. Treated domestic sewage sludge will have varying levels of nitrogen, depending on the method of treatment used. Most treatment plants decrease the level of total nitrogen in sewage sludge via cell synthesis and solids removal. However,…

Enhancing Biosolids Drying Through Solar Thermal Applications

The use of the sun for drying biosolids has been a time-tested method to reduce water and pathogen content. Biosolids are traditionally spread out over an open drying bed while the sun naturally dries them and reduces water content. However, the odour this process produces has made it difficult to manage in dense urban environments….

Challenges and Sustainability of Biosolids Management

In today’s tough economic climate, biosolids management faces new challenges in keeping their process not only sustainable but also cost effective. Increased public scrutiny and changing regulations have reduced the options for disposal making biosolids management a more complex task. In the US, biosolids management may differ from state to state. In California, for example,…
