How to Improve Sewage Sludge Treatment – A Water Industry AD Plant Performance Review
Anaerobic digestion has been shown to be the best technology for treating wastewater from sewage systems globally and is increasingly being used in sewage treatment. The properties of sludge can be modified during anaerobic digestion and produce biogas as a result of the treatment, as well as several positive effects on sludge management. Anaerobic digestion […]
Ultrasonic Disintegration for Higher Biogas Output from Biowastes
Ultrasonic Disintegration of biowastes especially sewage sludge is increasingly being used for the higher biogas output it provides from a relatively small and easily fitted device which provides a pretreatment stage before the digester tank at anaerobic digestion plants. Ultrasonics are a powerful method to break up or disintegrate cells so that they are available […]
Biogas Production from Sewage Sludge for Local WWTWs (Sewage Works)
Biogas production from sewage sludge is likely to become more common at ever-smaller sewage treatment plants. One of the leading companies that will achieve this for their clients is Weltec Biopower. Weltec Biopower is one of the AD firms using its biogas technology and making a big step into the wastewater treatment works industry. Their […]
Veolia and Anaerobic Digestion – Global Waste Company Embraces Circularity
In this article, we look at how Veolia and anaerobic digestion (AD) are progressing together, as an example of how one global waste company is building their investment in biogas technology as it embraces circularity across the business. This post is a compilation of our research, based upon the information provided by the company across […]
Egg Shaped Anaerobic Digesters – Strange Looking Tanks Explained
Egg Shaped Anaerobic Digesters; Enormous eggs! Whatever next! Have you ever wondered what those huge “strangely other-world like” not quite “spherical” tanks are that you sometimes see? They are anaerobic digestion process digesters, and very useful they are too! They make sewage sludge much more wholesome and in particular, they reduce sludge odour, but best […]
Sustainable NPK Fertiliser Technology Uses Digestate to Replace Non-renewable Alternatives
A new sustainable NPK fertiliser technology has been patented (using digestate) which makes a conventional NPK mineral fertiliser replacement tailored for customer’s fields. Not only does this technology utilise digestate fibre, but it also uses the carbon dioxide captured, either: during biogas upgrading to pure biomethane, or from the biogas engines used to generate electricity. […]
Biogas Yield from Sewage Sludge Increases Up To 30% in Existing AD Plants
Today we are delighted to report the good news that water utility companies in the UK are achieving a significantly improved biogas yield from sewage sludge, with increases of up To 30% in their existing AD Plants, through improved reliability and simple upgrades to their main reactor tank mixing equipment. Press Release 24 October 2020: […]
Low Cost Faecal Sludge Management and the Role of Anaerobic Digestion Co-Disposal
Before discussing low cost faecal sludge management and the role of Anaerobic Digestion Co-Disposal, let’s start by defining feacal sludge (also spelt “fecal”). Thankfully, that’s easy. Wikipedia tells us: Fecal sludge management (FSM) (or faecal sludge management in British English) is the collection, transport, and treatment of fecal sludge from pit latrines, septic tanks or […]
Sludge Digester Efficiency Improved Further at World-Class Nigg Plant
A sludge digester is a popular term used by many for an anaerobic digestion plant which is used for sewage sludge treatment. In this article we explain how the UK leads the way globally in sludge digestion technology. And in particular, how one advanced sludge AD Plant in Scotland has been further improved through a […]
What is Sewage Sludge? Biosolids and Wastewater Treatment Sludge Defined
If you are asking; “What is Sewage Sludge?” read on and you will find sewage sludge, biosolids and Wastewater Treatment Sludge is defined and explained here. What does SEWAGE SLUDGE mean? Source: Wikipedia.org article, adapted under this licence. Sewage sludge is the remaining, semi-solid material that is left over after the cleaned-up water is discharged […]
