A comparative study of the growth of Tetraselmis sp. in large scale fixed depth and decreasing depth raceway ponds
( Elsevier Ltd , 2016 , Article)In this study, an alternative approach was proposed where excess seawater would be added only during inoculation (DD) rather than daily addition (FD). Growth and metabolite contents of Tetraselmis sp. weren't affected for ... -
A comparison of bio-crude oil production from five marine microalgae – Using life cycle analysis
( Elsevier , 2022 , Article)Marine microalgae biomass could offer a viable feedstock for sustainably producing biofuel by hydrothermal liquefaction. In this study, five promising marine microalgae (i.e., Tetraselmis, Picochlorum, Synechococcus, ... -
Determination of Optimum Iron Requirement for Production of Microalgae Biomass as Biofuel Feedstock
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Microalgae biomass is considered as one of the promising alternative feedstock for biofuel production. The biomass productivity of some of the microalgae can exceed an order of magnitude compared to any other terrestrial ... -
Effect of harvesting methods on the energy requirement of Tetraselmis sp. biomass production and biocrude yield and quality
( Elsevier Ltd , 2019 , Article)A halo-tolerant Tetraselmis sp. was grown in a 100,000 L raceway pond in the Qatari desert environment. As the biomass density reached 0.679 g/L, after 7 days, five different harvesting methods (i.e., cross-flow filtration, ... -
Energy recovery and nutrients recycling from municipal sewage sludge
( Elsevier , 2020 , Article)Hydrothermal Liquefaction (HTL) could be a promising and better alternative to other techniques for energy recovery from municipal sewage sludge (MSS). However, the nutrients (i.e., N, and P) recovery potential from the ... -
Enhancing the electrocoagulation process for harvesting marine microalgae (Tetraselmis sp.) using interdigitated electrodes
( Elsevier , 2021 , Article)Marketable value of algal biomass has been increasing in recent years due to its wide range of applications. This study investigates the performance of a novel cylindrical interdigitated electrode array in electrocoagulation ... -
Microalgae biomass production in municipal wastewater and use of the produced biomass as sustainable biofertilizer
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference paper)Due to the lack of natural water sources, and cost and environmental issues associated with water desalination, Qatar currently emphasizes on the reuse of current wastewater sources, which includes conventional and ... -
Microalgae harvesting by pH adjusted coagulation-flocculation, recycling of the coagulant and the growth media
( Elsevier Ltd , 2016 , Article)Coagulation-flocculation can be considered as one of the least energy intensive microalgae biomass harvesting processes. However, cost of the coagulant and biomass contamination are two critical issues that need to be ... -
Optimization of iron dosage for microalgal biomass production as a feedstock for biofuel
( Taylor and Francis Ltd. , 2019 , Article)Summary: Biomass and metabolite production of three marine (Tetraselmis sp., Nannochloropsis sp., Chlorocystis sp.) and three freshwater microalgae (Scenedesmus sp., Chlorella sp., Monoraphidium sp.) were studied under ... -
Outdoor scale-up of Leptolyngbya sp.: Effect of light intensity and inoculum volume on photoinhibition and -oxidation
( Wiley , 2021 , Article)The effect of light intensity and inoculum volume on the occurrence of photooxidation for Leptolyngbya sp. QUCCCM 56 was investigated, to facilitate the transition from small-scale laboratory experiments to large-scale ... -
Pretreatment of cyanobacterial Chroococcidiopsis. biomass prior to hydrothermal liquefaction for enhanced hydrocarbon yield and energy recovery
( Qatar University Press , 2020 , Poster)Chroococcidiopsis sp. was grown in 200 L open raceway pond. Biomass density and average biomass productivity were 0.41 g/L and 16.1 g/m2/d. Chroococcidiopsis biomass was harvested by self-settling. Self settled biomass was ... -
Production of biolubricant from renewable feedstocks from Qatar
( Hamad bin Khalifa University Press (HBKU Press) , 2018 , Conference Paper)Due to increase in environmental pollution and decline in petroleum reserves, there is an increase in the demands of developing alternative renewable bio-based products. Petroleum and lubricant manufacturing companies are ... -
Production of phycocyanin from marine cyanobacteria in Open raceway pond
( Qatar University Press , 2020 , Poster)Phycocyanin is one of the major light harvesting accessory pigment present in microalgae and cyanobacteria. This water-soluble pigment protein exhibits antioxidant, anti-inflammatory, and neuroprotective effects. Application ... -
Study the Potential Use of Waste Water Grown Microalgae Biomass as Biofertilizer
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Liquid wastewater streams that contain nitrogen must be treated before being discharged into the environment to prevent eutrophication. Already there are several existing conventional treatment technologies that can remove ... -
A study to investigate the energy recovery potential from different macromolecules of a low-lipid marine Tetraselmis sp. biomass through HTL process
( Elsevier , 2022 , Article)This study investigated the hydrothermal liquefaction (HTL) of extracted major macromolecules from Tetraselmis sp. biomass. The carbohydrate fraction was first recovered from Tetraselmis biomass using pressurized heated ... -
Sustainable agriculture in the Arabian/Persian Gulf region utilizing marginal water resources: Making the best of a bad situation
( MDPI AG , 2018 , Article Review)One way to encourage agricultural self-sufficiency in arid regions is to increase the productivity of conventional freshwater agriculture. Another way is to develop and implement novel strategies and technologies that do ... -
Sustainable production of toxin free marine microalgae biomass as fish feed in large scale open system in the Qatari desert
( Elsevier Ltd. , 2015 , Article)Mass cultivation of microalgae biomass for feed should be cost effective and toxin free. Evaporation loss in Qatar can be as high as 2 cm/d. Hence, production of marine microalgae biomass in Qatar would also require ...
