Abstract BACKGROUND: In the presence of light, micro‐algae convert CO 2 and nutrients to biomass that can be used as a biofuel. closed photo‐bioreactors, however, light availability often limit algae production difficult control using traditional diffuser systems. this research, hollow fiber membrane photo‐bioreactor (HFMPB) was investigated to: (1) increase interfacial contact area available for gas transfer, (2) treat high nutrient strength (412 mg NO 3 − ‐N L −1 ) wastewater, (3) produce...

Abstract BACKGROUND Microalgae grown on wastewater are promising feedstocks for biomethane production by anaerobic digestion. However, the hemicellulose composition of microalgae cell wall inhibits hydrolysis intracellular substances and limits their digestibility. This study investigated enhancement rates during digestion Chlorella sp. using thermal pretreatment at varying temperatures. Experimental data were fitted to three simplified kinetic models an energy analysis was performed gain...
Algal blooms (ABs), often exacerbated by excess nutrients from anthropogenic activities, can pose serious risks to public health, fisheries, and ecosystem structure functions. Lake Okeechobee is located in southcentral Florida (USA), with a surface area of 1730 km2, it the largest subtropical lake United States. This shallow, nutrient-rich, subject frequent intense cyanobacteria, some which are toxic. In this study, three-dimensional (3D) model was developed, coupling long-term monitoring...
The effects of acclimatization microbial populations, compound concentration, and media pH on the biodegradation low concentration dichloromethane emissions in biofiltration systems was evaluated. Greater than 98% removal efficiency achieved for at superficial velocities from 1 to 1.5 m(3)/m(3). min (reactor residence times 0.7 min, respectively) inlet concentrations 3 50 ppm Although populations toluene occurred within 2 weeks operation start-up, initial took place over a period 10 weeks....
Laboratory and field experiments were conducted using a pilot‐scale compost biofilter (approximately 5.7 m 3 /min) to determine the potential of biofiltration for removing volatile organic compounds (VOCs) from gas streams at publicly owned treatment works. Six commonly found in wastewaters (benzene, trichloromethane, dichloromethane, toluene, tetrachloroethene, trichloroethene) selected quantitative evaluation removal efficiency. Gas fluxes through biofilters ranged 0.3 1.8 /m 2 ·min with...
Integration of algal biofuel production to wastewater anaerobic digestion infrastructure has the potential increase biogas production, decrease high and variable internal nitrogen loads, improve sludge digestibility dewaterability. In this research, two species microalgae, Spirulina platensis Chlorella sp. , were grown on centrate a nitrified effluent mixture. Harvested algae co‐digested with waste activated (WAS) at varying ratios. High‐growth (6.8 g m −2 ·d −1 ), (36.5 −3 phosphorus (6.5 )...
This study demonstrates the feasibility of combining microalgae, ammonia-oxidizing bacteria (AOB), and Anammox in a photosequencing batch reactor. Alternating light dark periods were applied to achieve biological nitrogen removal without mechanical aeration or external electron donor addition. process is termed ALGAMMOX (algal anaerobic ammonium oxidation) differs from SHARON–Anammox that oxygen generated during through microalgal photosynthesis, replacing aeration. Results bench-scale...
