Impacts of microalgae pre-treatments for improved anaerobic digestion: Thermal treatment, thermal hydrolysis, ultrasound and enzymatic hydrolysis

Ometto, Francesco; Quiroga, Gerardo; Psenǐckǎ, Pavel; Whitton, Rachel; Jefferson, Bruce; Villa, Raffaella (IWA Publishing, 2014-08-06)

Anaerobic digestion (AD) of microalgae is primarily inhibited by the chemical composition of their cell walls containing biopolymers able to resist bacterial degradation. Adoption of pre-treatments such as thermal, thermal ...
The impacts of replacing air bubbles with microspheres for the clarification of algae from low cell-density culture

Ometto, Francesco; Pozza, Carlo; Whitton, Rachel; Smyth, Beatrice; Gonzalez Torres, Andrea; Henderson, Rita K.; Jarvis, Peter; Jefferson, Bruce; Villa, Raffaella (Elsevier, 2014-02-24)

Dissolved Air Flotation (DAF) is a well-known coagulation–flotation system applied at large scale for microalgae harvesting. Compared to conventional harvesting technologies DAF allows high cell recovery at lower energy ...
Improving the energy balance of an integrated microalgal wastewater treatment process

Ometto, Francesco; Whitton, Rachel; Coulon, Frederic; Jefferson, Bruce; Villa, Raffaella (2014-04-01)

The inclusion of a microalgal system in a wastewater treatment flowsheet for residual nutrient uptake can be justified by processing the waste biomass for energy recovery. Low energy harvesting technologies and pre-treatment ...
Influence of light regime on the performance of an immobilised microalgae reactor for wastewater nutrient removal

Whitton, Rachel; Ometto, Francesco; Villa, Raffaella; Pidou, Marc; Jefferson, Bruce (Elsevier, 2019-10-23)

Microalgae immobilised within a resin shaped into beads have demonstrated the ability to remediate nutrients from wastewater effluents within hydraulic retention times as low as 3 h. Methods to further optimise performance ...
Influence of microalgal N and P composition on wastewater nutrient remediation

Whitton, Rachel; Le Mevel, Amandine; Pidou, Marc; Ometto, Francesco; Villa, Raffaella; Jefferson, Bruce (IWA Publishing, 2016-01-04)

Microalgae have demonstrated the ability to remediate wastewater nutrients efficiently, with methods to further enhance performance through species selection and biomass concentration. This work evaluates a freshwater ...
Microalgae for municipal wastewater nutrient remediation: mechanisms, reactors and outlook for tertiary treatment

Whitton, Rachel; Ometto, Francesco; Pidou, Marc; Jarvis, Peter; Villa, Raffaella; Jefferson, Bruce (Taylor and Francis, 2015-11-03)

This review explores the use of microalgae for nutrient removal in municipal wastewater treatment, considering recent improvements in the understanding of removal mechanisms and developments of both suspended and non-suspended ...
Microalgae to energy: biomass recovery and pre-treatments optimisation for biogas production integrated with wastewater nutrients removal

Ometto, Francesco (Cranfield University, 2014-01)

The increasing concern about water quality and energy demand promotes the development of innovative and low-cost processes to improve the nutrient uptake and energy efficiency of existing wastewater treatments (WWT). In ...
Tertiary nutrient removal from wastewater by immobilised microalgae: impact of wastewater nutrient characteristics and hydraulic retention time (HRT)

Whitton, Rachel; Santinelli, Martina; Pidou, Marc; Ometto, Francesco; Henderson, Rita; Roddick, Felicity; Jarvis, Peter; Villa, Raffaella; Jefferson, Bruce (IWA Publishing, 2018-03-15)

Immobilising microalgal cells has been proposed as a process solution to overcome the barriers associated with the implementation of microalgae for wastewater remediation. This work evaluated the performance and remediation ...
