Performance study for anaerobic digestion of municipal solid waste in a single phase reactor
Anaerobic Digestion (AD) has been up to now essentially applied to wastewater. However, anaerobic treatment of organic solid waste fits well with the new requirements for waste management. A batch study of vegetable market waste composed at various solid concentrations was studied in a single phase anaerobic reactor. Prior to this, studies were also carried out in aspirator bottles of different ...

Anaerobic Digestion Reduces Microplastics in Sludge
Anaerobic digestion can help remove microplastics — a large cause of water pollution — during the sewage treatment process Microplastics, or tiny fragments of plastic, include microbeads, the plastic pellets present in thousands of household and personal care products, including toothpaste, cosmetics, and beauty scrubs. They also include fragments from the breakdown of anything in ...

2018 Hurricanes Contaminated Wells Across the Southeast
Some agricultural waste lagoons that dot North Carolina’s agricultural regions overflowed during the 2018 storms, contaminating groundwater with pathogens. Agricultural waste and private septic systems were major sources of pollutants Major hurricanes Florence and Michael, which hit the Southeastern United States in 2018, not only killed approximately 70 people and caused an estimated ...

Study: Anaerobic Digestion Reduces Microplastics in Sludge
Microplastics, including the microbeads found in many cosmetics and household products, are an increasing source of water pollution. Anaerobic digestion can help remove microplastics — a large cause of water pollution — during the sewage treatment process Microplastics, or tiny fragments of plastic, include microbeads, the plastic pellets present in thousands of household and ...

How Many Anaerobic Digesters Are in the US?
There is enormous potential to increase the extraction of energy from farm waste Agricultural waste is one of the largest sources of methane emitted into the atmosphere from human activities. Methane is a potent greenhouse gas but it’s also highly combustible, making it a valuable source of renewable energy when captured. Anaerobic digesters can convert farm waste into methane-rich ...

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 ...

Examination of food waste co-digestion to manage the peak in energy demand at wastewater treatment plants
Many digesters in Germany are not operated at full capacity; this offers the opportunity for co-digestion. Within this research the potentials and limits of a flexible and adapted sludge treatment are examined with a focus on the digestion process with added food waste as co-substrate. In parallel, energy data from a municipal wastewater treatment plant (WWTP) are analysed and lab-scale ...

Regenerative thermal oxidizer - Wastewater treatment facility
Epcon has extensive experience in designing and building Air Pollution Control Systems for the Wastewater Treatment Industry. The Problem The water treatment plant could no longer have open storage tanks to store industrial wastewater from the refineries in the area. They were emitting VOC's from their open storage tanks and were required to reduce their VOC emissions by 98%. The Process The ...

Implications of full-scale implementation of an anammox-based process as post-treatment of a municipal anaerobic sludge digester operated with co-digestion
The feasibility of treating the supernatant of a municipal sludge digester supplemented with co-substrates by means of an anammox-based process (ELAN®) was tested in Guillarei (NW of Spain). Ammonia concentration measured in the supernatant of the sludge digester varied in the range 800–1,500 g N/m3 due to the fact that the sludge produced in the plant was co-digested with wastes ...

Full scale experience of retrofitting thermal hydrolysis to an existing anerobic digester for the digestion of waste activated sludge
ABSTRACT Naestved central WWTP is a 5 MGD facility that was originally designed as a Bio DeNiPho plant following primary sedimentation. In 1998 the primary tank was bypassed in order to reduce organic micro-pollutants by aerobic treatment in the aeration basins. This reduced the micro-pollutants but led to a bulky undigestible sludge and foaming due to Microthrix. The Microthrix problem was ...

Treatment of waste activated sludge together with agro-waste by anaerobic digestion: focus on effluent quality
Waste activated sludge production and management plays an important role in wastewater treatment plants (WWTPs), especially from an economic point of view. One possible approach is the anaerobic co-digestion of waste activated sludge with others organic substrates in mesophilic and thermophilic conditions in order to exploit the spare volume of existing reactors, recover energy from biogas ...

Waste Water Treatment Processes Explained
SUNCOAST WASTE WATER MANAGEMENT presents AEROBIC -verses- ANAEROBIC THE AEROBIC PROCESS There are two basic types of sewerage treatment processes, which are the Aerobic process and the Anaerobic process. Aerobic means with air or oxygen and Anaerobic (septic) means without air or oxygen. Aerobic bacteria are a higher life form and when digesting waste are utilising dissolved oxygen or air ...

Removal of fats, oils, & grease (F.O.G.) from grease traps and lift stations by means of advanced oxidation processing (A.O.P.) using the
Scenario: F.O.G. (Fats, Oils & Grease) deposits in both grease traps and lift stations accumulate within a short period of time. Their removal requires high-pressure Vac-Trucks and hazardous chemicals to break down and remove the unwanted build-up. Problem: Several problems occurring because of grease accumulation are: 1.) Clogged sewer lines 2.) Sanitary sewer overflows (SSO's) 3.) Raised ...
