Sludge Digestion
The Sludge Digestion Process Explained
Welcome to our in-depth explanation of the municipal wastewater sludge digestion process which is used at Activated Sludge Aeration WwTWs which now means the vast majority of global WwTWs. In modern times, wastewater treatment plants (WWTPs) have become increasingly sophisticated in their approach to waste management. One of the most important processes within any WWTP […]
Anaerobic Wastewater Treatment – An Introduction to Sustainable
Read on if you would like to discover the basics behind the anaerobic treatment of wastewater. “The amount of wastewater produced globally increases in tandem with the global population. To safeguard human health and the environment, proper wastewater management is essential.” The use of anaerobic bacteria to clean wastewater has become increasingly common in recent […]
Sludge Blockages in Biogas Pipes Solved
Sludge blockages can cause a reduction in biogas output, which can be cured using an inline Mono Muncher for its tearing, shearing and crushing action. If your biogas yield drops unexpectedly, it could be due to a problem with your digester’s sludge homogeneity. It’s possible that your system isn’t mixing efficiently, and if your internal […]
Sewage Sludge Digestion – Ofwat UK Rule Changes Allow Outsourced Treatment
Five years ago, in this article, we announced that sewage sludge digestion would be put out to tender as an outsourced service by many, or all UK water companies. The opinion we gave was that there would be big opportunities from Ofwat for companies to take sewage sludge and co-digest it. We looked forward to […]
Hydrolysis of Sewage Sludge and Anaerobic Digestion Wins
The hydrolysis of sewage sludge and the subsequent anaerobic digestion of the hydrolysed sludge output is becoming increasingly common at many sewage works. We think we are justified to call it a winning combination, and we even back up this assertion by providing information on a new contract win for the technology by Veolia, in […]
Wastewater Treatment Sludge Mixing Improvements Raise Plant Efficiency
Wastewater Treatment Sludge Mixing Case Study: Landia the leading producer of specialist water treatment pumps, mixers, aeration systems and advanced processes, has drastically lowered sludge disposal costs and is saving valuable landfill space at a large WwTW in the US. In the words of the Superintendent of the Sewer Authority: “The Landia mixers have been […]
How Ultrasonic Disintegration of Sewage Sludge Improves Wastewater Treatment Plant Biogas Outputs
Sewage sludge is notoriously slow to digest. Ultrasonic disintegration provides an environmentally responsible way to improve biogas output. Unsurprisingly wastewater treatment works biogas plant operators have been first to adopt ultrasonic disintegration. As the technology becomes further developed there is no reason why the AD industry won’t also adopt it’s use for other similarly slow […]
Co-disposal of Food Waste and Sewage Sludge ADBA Show to Host Debate
The idea of co-digestion of food waste and sewage sludge, is new to the UK but the obvious good-sense of it is gaining traction, and the ADBA Biogas/ Bioresources Trade Show this July will host an important debate on the subject. When the UK water industry was privatised in the 1980s, nobody conceived that sewage sludge […]
Biomethane from Sewage Sludge at Minworth STW Heats 3,000 UK Homes
This is the story of how one UK water utility company is making biomethane from sewage sludge and helping the UK meet emissions reduction targets. They are purifying biogas into pure methane (biomethane) renewable energy, and reducing carbon dioxide emissions substantially. They are doing this by using their own sewage sludge waste product at Minworth Sewage […]
