Howard Tenens Andover Logistics Hub Modular Digester - Case Study
Located at Howard Tenens Andover logistics hub, the food waste is processed in two ModularDigesters (comprising 36m3 of digestion volume). The system also comprises a gas mixing pod, biogas storage bladder, control panel, digestate store and 7.5kW CHP. In addition this system also has a biogas upgrader enabling the biogas to be cleaned to 97% methane and compressed to 300 bar and used as a ...

Velocity gradient as a tool to characterise the link between mixing and biogas production in anaerobic waste digesters
Whilst the importance of mixing in anaerobic digesters to enhance process performance and gas production is well recognised, the specific effects of mixing regime on biogas production are not clear. Here, the velocity gradient is used to demonstrate the importance of minimally mixed zones in a digester, with computational fluid dynamics (CFD) models indicating that 20–85% of a ...

Energy self-sufficient sewage wastewater treatment plants: is optimized anaerobic sludge digestion the key?
The anaerobic digestion of primary and waste activated sludge generates biogas that can be converted into energy to power the operation of a sewage wastewater treatment plant (WWTP). But can the biogas generated by anaerobic sludge digestion ever completely satisfy the electricity requirements of a WWTP with ‘standard’ energy consumption (i.e. industrial pollution not treated, no ...

Modification of UASB reactor by using CFD simulations for enhanced treatment of municipal sewage
Up-flow anaerobic sludge blanket (UASB) has been in use since last few decades for the treatment of organic wastewaters. However, the performance of UASB reactor is quite low for treatment of low strength wastewaters (LSWs) due to less biogas production leading to poor mixing. In the present research work, a modification was done in the design of UASB to improve mixing of reactor liquid which ...

Two-phase anaerobic digestion for class a biosolids at moccasin bend WWTP
The Moccasin Bend Wastewater Treatment Plant (WWTP) provides treatment for the City of Chattanooga, Tennessee and the surrounding region. The City has completed upgrades to the solids handling facilities to treat and dewater the primary solids and waste activated sludge (WAS) from the WWTP. This paper summarizes the process to handle the primary solids and the start-up process. Primary solids ...

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 ...

The Wastewater Treatment Process
What is Wastewater? Wastewater is classified as used water from any combination of domestic, industrial, commercial, agricultural activities, surface runoff, or storm water. The wastewater treatment process removes the contaminants from the wastewater and converts it into an element that can be returned to the water cycle with minimum impact on the environment. Water can carry harmful diseases ...

Thermal protection - WWTF gets ahead of the curve with thermal mass flowmeters
For the Santa Cruz Wastewater Treatment Facility (WWTF), dependability matters. Since 1989, this state-of-the-art WWTF, nestled in a shallow canyon in the coastal city of Santa Cruz, Calif., has been leading the way for renewable energy programs and environmental protection in the West. Santa Cruz WWTF generates its own electric power by using internal combustion engines that burn a mixture of ...

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 ...
