The primary objective of wastewater treatment is to process domestic sludge before recycling it into productive materials such as fertilizers or feeding it back into the water system. Based on the wastewater quality, biosolids are classified into Class A and Class B. Class A is a type of sterilized sludge that is used for land […]

A team from the University of Waterloo and Northeastern University have collaborated with Wyss Institute to find a biological solution for wastewater filtration and further innovations in wastewater treatment. Conducted at Harvard University, the study wanted to compare the effectiveness of a standard filter and a liquid-gated membrane filter in terms of pressure requirements and […]

If there is one thing that makes treating wastewater challenging, is controlling the noxious odours caused by ammonia. Ammonia is the by product of the breakdown of animal and vegetable matter and is what gives organic waste its unpleasant smell. But a new study in the United Kingdom may offer a possible solution for this […]

For farmers, soil is where life on the farm begins. Keeping soil healthy is a top priority to ensure a bountiful crop production. To maintain soil health, farmers have to create a conducive environment that fosters populations of beneficial organisms while minimizing pests. Soil must include high levels of decomposed organic matter that allow it […]

Growing concerns about global climate change has prompted the need to develop feasible methods to reduce the atmospheric levels of greenhouse gases (GHGs). Human activities such as combustion of carbon-based fuels, cement manufacturing, deforestation, burning of biomass, and and animal husbandry is blamed for the increase in carbon dioxide in the atmosphere. Researchers have found […]

Australia’s New South Wales region has recently experienced one of the worst droughts in living memory, yet farmers in the area have been able to cope with the help of biosolids. This organic fertilizer has been used in around 30 farms to turn otherwise dry land into arable soil. Sydney Water has sourced these biosolids […]

Red tide is common in southwest Florida. Over the years, many aquatic animals have been killed by this deadly phenomenon including manatees, dolphins and sea turtles, not to mention thousands of fish. The carcasses of these animals rot and emit putrid odours that affect the health and wellbeing of communities in the area. Scientists have […]

Agricultural lands have experienced a significant boost in yields thanks to a better understanding of plant physiology and biochemistry. Farmers are even able to make soils more favorable for plant growth due to the introduction of fertilizers. Currently, there are two types of fertilizers, the commercially available inorganic fertilizer and the other is organic fertilizer […]

Biosolids have continued to find new avenues where it can be utilized commercially. It has been converted to fertilizers and even biocrude in some parts of the world, but another unique solution comes from Malaysia. Atiyyah Ameenah Azni, who has a degree in science biotechnology from International Islamic University Malaysia (IIUM) has invented the Biomass […]

Biosolids are the nutrient-rich organic materials that stem from the treatment of sewage sludge. It contains essential plant nutrients and organic matter that when treated and processed, can be recycled as fertilizers. Biosolids are beneficial in improving and maintaining productive soils that stimulate plant growth. Over the years, advancements in wastewater treatment technology has made […]
