Why Is There Diversification of Anaerobic Digester Designs?
Engineers consider a range of factors — including the waste to be treated and the desired outcome — when designing an AD system Anaerobic digestion (AD) is a well-established technology for the treatment of organic waste streams. It harnesses the power of microorganisms in an oxygen-free environment to decompose organic matter, generating renewable biomethane as a byproduct and ...

Alternative stabilisation options of mechanically sorted organic fraction from municipal solid waste prior to landfill disposal
In order to foresee the measures of the Directive 1999/31/EC, waste management policies are focused on the reduction of organic matter landfill disposal, through the recovering of the organic waste stream or the pre-treatment of residual wastes before landfilling. This paper discusses the advantages and disadvantages of possible stabilisation treatments of the mechanically sorted organic fraction ...

Green Village Delft – integration of an autarkic water supply in a local sustainable energy system
For the Green Village at the campus of Delft University of Technology, an autarkic water circuit was developed. The aim was to avoid connections to the public water supply system, the sewerage, the electricity grid and cable systems. It should produce its own drinking water and electricity, and clean its organic waste streams in a sustainable way. Due to the strict Dutch drinking water ...

Aquidneck Place wastewater system information
Institutional facilities typically have larger wastewater flows with lower organic concentration than commercial waste streams. However, some institutions such as schools may have exceptionally high concentrations of ammonia nitrogen and very erratic peak flows. It is critical to understand the institution’s lifestyle and sanitary routines when designing a treatment system. The Aquapoint ...

Types of Anaerobic Digesters
Biogas, a methane-rich mix of gases created by anaerobic digestion, can be burned to generate electricity or heat, or it can be processed further to produce a valuable source of renewable energy. Different technologies can be used to tailor a solution that makes the most of specific feedstocks Anaerobic digestion is a natural biological process in which bacteria decompose organic matter in ...

What is energy recovery?
Processes like incineration and anaerobic digestion not only provide sources of energy, but they also reduce waste volume The term “energy recovery” often is applied only to a narrow number of methods for converting wastes into energy, when in fact it applies to a broad range of technologies used to create heat, electricity, or fuel. Energy recovery gives governments and businesses ...

Water Recovery Project
The Commercial Opportunity Fielding considers it a matter of environmental ethics to extract and repurpose anything of value from the waste streams it handles, wherever feasible. For some streams, however, the cost of separation exceeds the value of its components. Such streams require some form of ultimate disposal. For hazardous liquid wastes there are few environmentally acceptable disposal ...

Molecular Chemical Grinder Improves Digestion in Sludge
Municipal wastewater treatment plants (WWTPs) can reduce the costs and liabilities of sludge handling and disposal and increase their organic solids conversion rate with the Advanced Fluidized Composting (AFC) Process or the Advanced Fluidized Co-Digeson & Co-Generaon (AFC2) Process from BioConversion Soluons, LLC (BCS). The conventional sludge treatment techniques of aerobic and anaerobic ...

Wash Water Questions and Answers
When the subject of Wash Water Recycling comes up there are many questions that can arise. The following are a few that are frequently asked are: Will it have an odor? What will its’ clarity be? How much is recycled? The above questions seem very basic but can at times create a complex response because of the specific application. Let’s explore each question independently. ...

Mechanical Biological Treatment (MBT): The new kid on the UK waste management block
Waste management in the United Kingdom (UK) has undergone a revolution in the past 20 years. In 1990, the UK landfilled more than 90 percent of its municipal solid waste (MSW), incinerated about 8 percent and recycled the remaining 2 percent. It had one the highest landfill rates in Western Europe and one of the lowest recycling rates, reflecting the UK’s mining traditions and aggregates ...

The baccelerator from cleveland biotech solves discharge consent problems at college case study
A large residential College in the north of England housing 550 live-in students and 450 non-resident staff operates its own on-site effluent treatment plant to treat all foul waste arising before discharge to local sewer. The effluent plant constructed in 1991 comprises an inlet settlement tank at the head of the works from where the clarified influent feeds by gravity the coke filtration ...

BM Respirometry benefits for activated sludge process management, research and training
A biological process controlled by non-biological measurements? All treatment plant efficiencies are geared to the waste that they receive. The microorganisms found in the waste need food and oxygen to survive, the food is provided as soluble organic carbon in the waste stream and the oxygen is obtained through the aeration process in the treatment plant. Once a treatment plant has been built, ...

Making wet waste destruction a sustainable reality
Irish environmental company SCFI was supported by the European Union’s Eco-Innovation initiative in a project to build a portable unit to demonstrate its innovative AquaCritox wet waste treatment technology. This White Paper describes the science behind hydrothermal oxidation (HTO) as a waste treatment methodology and its potential across a range of industrial applications, which is now, ...

Anaerobic Digestion—What Are the Economics?
Although solid waste AD facilities are just starting to emerge, haulers and their customers may see some benefits if the development trend continues. A Pro Forma Model objective can be constructed for strategic planning of an anaerobic digestion facility. Anaerobic digestion (AD) of food wastes in the U.S. is a developing market that is poised for continued growth in many regions. Although solid ...

When Is It Best to Use Anaerobic Digestion?
The benefits can be compelling, but several factors must be considered Anaerobic digestion is a biological process that breaks down organic matter in the absence of oxygen, producing biogas and nutrient-rich sludge. Used in wastewater treatment, anaerobic digestion helps reduce the volume of sludge, stabilizes the solids, and produces valuable biogas. The solid matter that remains, called the ...
