The most difficult challenge facing any water treatment facility is sewage treatment odour control. Whatever benefits the plant may bring are often overshadowed by the stigma of the odours it emits. Even government regulations cannot properly determine the performance indicators needed to make these plants neighborhood friendly. These odours could waft into parks and other […]

The advantages of biosolids in agriculture are clear. They are naturally abundant in nutrients such as nitrogen and phosphorus that help farmers enrich the soil without the use of chemical fertilizers. Because they contain organic matter, they are less water soluble and the nutrients are less likely to leach into groundwater or be easily washed […]

The Ontario Soil and Crop Improvement Association (OSCIA) recently implemented a program to improve its manuring in agriculture efforts and enhance soil health. The program would make a significant investment in qualified nutrient applicators to enhance their systems by offering a 60% cost-sharing scheme which maxes out at $25,000. Wastewater from household and industrial sources […]

Sludge, or the accumulation of waste products that end up in the sewage, contains a considerable amount of water. Before any form of sewage treatment or disposal of waste takes place, water must first be removed from the sludge. Thus, a dewatering management plan is key to the effective treatment of sewage and production of […]

In Canada and the United States, biosolids recycling is seen as an environmentally sound and affordable method for managing wastewater. When done according to stringent regulations, biosolids can help communities protect the environment by providing a safe source of organic fertilizers. In Ontario, sewage sludge is required by law to be pre-treated in accordance with […]

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 […]

The main goal of proper wastewater treatment is to keep sewage sludge disposal safe for human health and ensure minimal negative effect on the environment. Wastewater odour control was not an issue until communities started developing near treatment facilities. Complaints started flooding wastewater treatment plant managers who were pressured to quickly address the problem. Thus, […]

Canada is known for its water with its abundance of rivers, lakes, and three oceans. It is also home to the largest fresh water lakes in the world. But when it comes to wastewater, most Canadians flush the toilet not thinking about where it all ends up. There are many innovative companies that are now […]

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. […]

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, […]
