Anaerobic membrane bioreactors (AnMBR) treating urban wastewater in mild climates

2020

[EN] Feasibility of an AnMBR demonstration plant treating urban wastewater (UWW) at temperatures around 25-30 degrees C was assessed during a 350-day experimental period. The plant was fed with the effluent from the pretreatment of a full-scale municipal WWTP, characterized by high COD and sulfate concentrations. Biodegradability of the UWW reached values up to 87%, although a portion of the biodegradable COD was consumed by sulfate reducing organisms. Effluent COD remained below effluent discharge limits, achieving COD removals above 90%. System operation resulted in a reduction of sludge production of 36-58% compared to theoretical aerobic sludge productions. The membranes were operated a…

Progress in EU Breeding Blanket design and integration

2018

Abstract In Europe (EU), in the frame of the EUROfusion consortium activities, four Breeding Blanket (BB) concepts are being developed with the aim of fulfilling the performances required by a near-term fusion power demonstration plant (DEMO) in terms of tritium self-sufficiency and electricity production. The four blanket options cover a wide range of technological possibilities, as water and helium are considered as possible coolants and solid ceramic breeder in combination with beryllium and PbLi as tritium breeder and neutron multipliers. The strategy for the BB selection and operation has to account for the challenging schedule of the EU DEMO, the ambitious operational requirements of …

Instrumentation, control, and automation for submerged anaerobic membrane bioreactors

2015

A submerged anaerobic membrane bioreactor (AnMBR) demonstration plant with two commercial hollow-fibre ultrafiltration systems (PURON® , Koch Membrane Systems, PUR-PSH31) was designed and operated for urban wastewater treatment. An instrumentation, control, and automation (ICA) system was designed and implemented for proper process performance. Several single-input-single-output (SISO) feedback control loops based on conventional on off and PID algorithms were implemented to control the following operating variables: flow-rates (influent, permeate, sludge recycling and wasting, and recycled biogas through both reactor and membrane tanks), sludge wasting volume, temperature, transmembrane pr…

Energy and environmental impact of an anaerobic membrane bioreactor (AnMBR) demonstration plant treating urban wastewater

2020

Abstract In order to assess the environmental feasibility of anaerobic membrane bioreactor (AnMBR) technology for urban wastewater (UWW) treatment at ambient temperature, a demonstration plant was operated within the LIFE MEMORY project ( http://www.life-memory.eu/en/ ). This plant incorporates full-scale hollow-fiber membrane modules and was fed with the effluent from the pre-treatment of the “Alcazar de San Juan” WWTP (Alcazar de San Juan, Ciudad Real, Spain). Because of the dimensions of this plant, the system can be regarded as a previous step to the scale-up of AnMBR technology for full-scale UWW treatment. High-energy recovery potentials were achieved treating medium-/high-loaded UWW …
