Algae Helps Purify Wastewater Sludge in India

In India, as much as 80% of the surface water is polluted resulting mostly from untreated wastewater sludge. Another culprit is industrial waste which comes in the form of dyes and other chemicals that are disposed of during textile production. Because textile production is widespread across India, finding a remedy for the pollution is a…

What are the Beneficial Uses of Biosolids?

What are the Beneficial Uses of Biosolids? Managing wastewater has become an important aspect of environmental protection because if left untreated, sewage sludge can cause harm to the community. Another benefit to treating wastewater is the collection of biosolids that can be recycled into many practical applications. Below are some beneficial uses of biosolids. An…

Australian Company Uses Biosolids as an Alternative Energy Source

One of the leading global concerns of today is the proliferation of sewage. With the advent of wastewater treatment solutions, the resulting biosolids are being processed into more useful forms such as fertilizer. But for biosolids to achieve higher adoption, it would have to be converted into a product that can be used as an…

Vancouver Derives Energy from Sewage Treatment

Metro Vancouver is developing a $700 million wastewater treatment plant that will derive energy from sewage. The North Shore Wastewater Treatment Plant (NSWWTP) will be one of the largest heat recovery systems in British Columbia. The $525-million design-build-finance contract for the NSWWTP was awarded to Acciona Wastewater Solutions LP in April 2017 for Metro Vancouver’s…

Wastewater Treatment Odor Control with Ecosorb

Wastewater treatment odor control is a constant challenge for wastewater treatment plants. It has been a primary concern for many communities and is a major issue with legislators trying to enact adequate measures to mitigate the problem. The smell that comes from processing waste originates from the anaerobic bacteria that consume the organic material in…

Biosolid Waste Can Now Be Utilized to Make Bricks

Biosolid waste have traditionally been processed into things such as fertilizer, compost, and biogas. But a new study has looked into converting biosolid waste into bricks. It would become an ideal solution for developing renewable materials for construction making it affordable and readily available. The United States produces about 7.1 million tonnes of biosolids, the…

Factors that Affect the Development of Activated Sludge in Wastewater Treatment

The presence of bacteria is vital for the wastewater treatment process. In an ideal wastewater treatment plant system, bacteria (about 95%) along with a small portion of fungi and protozoa should form a biological floc that is known as an activated sludge. This is essential for the degradation of organic substances in wastewater. The activated…
