Energy utilization in sewage treatment – a review with comparisons
In recent years, the operating cost of sewage treatment plants (STPs) in some parts of the world has been rising due to increases in the cost of energy. STPs have focused on energy reduction and recovery from treatment processes in order to lower energy consumption. The development involves the improvement of capital set-up for treatment plants in terms of equipment upgrading/plant sizing as ...

Reductions in greenhouse gas (GHG) generation and energy consumption in wastewater treatment plants
Greenhouse gas (GHG) emission and energy consumption by on-site and off-site sources were estimated in two different wastewater treatment plants that used physical–chemical or biological processes for the removal of contaminants, and an anaerobic digester for sludge treatment. Physical–chemical treatment processes were used in the treatment plant of a locomotive repair factory ...

RHEINISCHE BIOESTER - Anaerobic wastewater treatment in biodiesel production - Case Study
Some processes during the production of biodiesel, such as glycerine evaporation, fatty acid and methyl ester drying (vapour condensate), generate wastewater which is highly contaminated with organic substances. The most significant substances in the wastewater are glycerine, methanol and free fatty acids. EnviroChemie supplies biological wastewater treatment plants with biogas recovery for the ...

Vacuum sewerage systems – a solution for fast growing cities in developing countries?
Developed more than a century ago, the potential of vacuum sewerage systems remains underexploited. At the same time, the rapid urbanization in Asia brings about major challenges for municipal utilities. In this context, the GIZ (Deutsche Gesellschaft fuer Internationale Zusammenarbeit) project ‘Integrated Resource Management in Asian Cities: the Urban Nexus’ gives technical advice to ...

Is human excreta a waste?
Every day a huge amount of excreta is being produced by human society and it is also considered one of the most unwanted waste/refuse of the society because of its nuisance and diseases causing characteristics. However, it is also utilised as a fertiliser and soil conditioner in several countries such as India and China. Presently most common sanitation concept is centralised treatment of human ...

GTI helps keep Kamloops beautiful - case study
The City of Kamloops is located in the interior of British Columbia, Canada’s westernmost province. As part of Kamloops’ Liquid Waste Management Plan, the city was seeking opportunities to use its wastewater as a resource, rather than treat it solely as waste. One method was to capture methane gas (biogas) produced from the anaerobic treatment of wastewater and use it to generate ...

Unmanned remote and wireless CDM monitoring case study
Remote and wireless monitoring technology to meet CDM requirements is in its infancy in Europe. Carbon trading is driving it globally, especially in North and South America. That experience and technology is now finding a demand in Europe and Asia in landfill, biogas from food and animal waste in digesters and water treatment sludge digestion. Methane recovery from landfill and anaerobic ...

Biogas and the Food and Beverage Industry
Food and beverage operations are ideally positioned to enter the circular economy with waste-to-energy systems The food and beverage (F&B) industry is known for its high-load wastewater. In general, it’s estimated that wastewater sent to treatment utilities contains five times the energy needed to treat it, but the streams from F&B operations are often laden with fat, oil, and ...

Inflation Reduction Act to Boost Biogas Projects in the United States
With an underdeveloped waste-to-energy market, new legislation promotes greater adoption of anaerobic digestion On August 16, United States President Biden signed the $750 billion Inflation Reduction Act (IRA) into law and biogas industry groups immediately hailed its hefty incentives for anaerobic digestion, a technology that recovers energy from waste in the form of ...

How Much Energy Can Anaerobic Digestion Produce?
The total energy produced can vary widely depending on factors including what is being treated Anaerobic digestion is a waste treatment process that breaks down organic matter with bacteria that thrive in the absence of oxygen. Feedstocks can include manure, sewage biosolids, and food wastes. Among anaerobic digestion’s advantages is its ability to treat high-load streams while producing ...

Energy and phosphorus recovery from black water
Source-separated black water (BW) (toilet water) containing 38% of the organic material and 68% of the phosphorus in the total household waste (water) stream including kitchen waste, is a potential source for energy and phosphorus recovery. The energy recovered, in the form of electricity and heat, is more than sufficient for anaerobic treatment, nitrogen removal and phosphorus recovery. The ...

The effect of mixing conditions on anaerobic digester performance
The basic principle of aerobic wastewater treatment is the conversion of some parts of organic matters to biomass and this causes production of excessive sludge in aerobic processes. This excessive sludge is withdrawn from time to time to prevent accumulation of biomass in aeration basin. In most cases, this sludge requires the stabilization before the dewatering and disposal. Different processes ...

Biomethanation of solid wastes: analysis of case studies
Management of the organic fraction of urban solid waste using anaerobic procedures will contribute to the reduction of greenhouse gas emissions, and using biogas, which is a carbon neutral energy, to generate electrical energy will eventually help in reducing the combustion of fossil fuel. Energy recovery in the form of biogas from Municipal Solid Waste (MSW) generated in three different ...

Resource recovery from source separated domestic waste(water) streams; full scale results
A major fraction of nutrients emitted from households are originally present in only 1% of total wastewater volume. New sanitation concepts enable the recovery and reuse of these nutrients from feces and urine. Two possible sanitation concepts are presented, with varying degree of source separation leading to various recovery products. Separate vacuum collection and transport followed by ...

Saving water: complete water recycling for industry - Case Study
Access to clean water is a basic requirement for effective production. In Brazil, however, many regions suffer from acute water shortages. Some urban centres where large numbers of industrial enterprises have moved in, such as São Paulo, Rio de Janeiro or Belo Horizonte, are facing the worst water crisis in over 84 years, as Brazil's environment minister, Izabella Teixeira, explained in ...

Screw Press Machine in Biogas Slurry Dewatering
Biogas production is a sustainable and environmentally friendly way to generate energy from organic waste. However, the process generates a byproduct called biogas slurry, which is rich in nutrients but also high in water content. Managing this slurry efficiently is crucial for reducing transportation costs, controlling odors, and maximizing the benefits of nutrient-rich byproducts. In this ...

Turning whey into energy
Sweden, Umea. Olof Wallin stared at the official letter on the desk in front of him and thought hard. Under his management the dairy in Norrmejerier produced more milk products every year, cheese production too was on the rise, and now this. The public canalization could no longer handle the whey which was a waste product of the daily cheese production and disposed of with the dairy’s ...
