Carbon Limitation in Periphytic Algal Wastewater Treatment Systems
… sustainability of natural resource consumption. Wastewater treatment facilities (WWTF) are designed to destroy pathogens, remove particulates, lower oxygen demanding substances, and reduce nutrients from influent waste water to avoid the degradation of receiving waters. WWTF are generally …

Investigating Ammonium Toxicity In The Performance Of Recirculating Periphytic Algal Wastewater Treatment Systems
<p>Freshwater nutrient enrichment from wastewater facilities and other sources can lead to freshwater eutrophication, a threat to global aquatic ecosystems. Mechanical and chemical ways to curb this threat are either too expensive or not sustainable, and thus, not feasible. Compared to mechanical …

Algal Wastewater Treatment and Biofuel Production: An assessment of measurement methods, and impact of nutrient availability and species composition
… consumption of fossil fuels. Using algae for wastewater treatment and biofuel production offers one approach to progress towards these goals simultaneously. Algae are capable of removing nutrients from wastewater and carbon dioxide from the air, and the biomass formed in that process can be …

Adsorbent-based algal cultivation system to facilitate integration of algal biofuel production with wastewater treatment
Although combining algae cultivation with wastewater treatment has been highlighted as a promising pathway for sustainable biofuels, there are still several challenges that limit the ability to use algae for biological wastewater treatment. First, the treatment performance of an algal wastewater …

Impact of daytime nitrogen limitation on structure and function of mixed microalgal communities derived from three geographically distinct sources
… (P) loadings to surface waters lead to algal blooms which cause eutrophication and hypoxia, threatening aquatic ecosystems, human health, and local economies. The adoption of increasingly stringent regulations for effluent N and P loadings, including from wastewater treatment plants …

Characterizing the effects of hydrothermal processes on bioactive compounds in wastewater bioenergy systems
… wastes, such as animal manures, municipal wastewater, and food processing wastes. In particular, we analyzed the impacts of a novel integrated process combining algal wastewater treatment with hydrothermal liquefaction (HTL) on the fate of emerging bioactive contaminants (i.e., …

Microalgal Biodiesel Production through a Novel Attached Culture System and Conversion Parameters
… to produce the algae while recycling dairy farm wastewater using the microalga Chlorella sp. The first part of the study provided a feasibility study as the attachment of the alga onto the supporting substrate as well as determining the pretreatment options necessary for the alga to grow on …
