Microbial nutrient recovery cell as an efficient and sustainable nutrient recovery option in sewage treatment

Journal of Environmental Management
Globally, nutrient pollution is a serious and challenging concern. Wastewater treatment plants (WWTPs) are designed to prevent the discharge of contaminants resulting from anthropogenic sources to the receiving water bodies. In this study, seasonal nutrient pollution load, and biological nutrient removal efficiency of an anoxic aerobic unit based WWTP ...

Assessing Extractive Nutrient Recovery as a Viable Nutrient Control Alternative

Proceedings of the Water Environment Federation, 2013
This paper presents a state of the science review of nutrient recovery technologies with a special emphasis on bridging the knowledge gap currently faced by utilities when considering nutrient recovery for nutrient management. In this paper, we suggest technology classification into accumulation-release-recovery and discuss challenges against and ...

Mineral nutrient recovery from pyrolysis systems

Environmental Progress & Sustainable Energy, 2012
AbstractBioenergy plants such as sorghum, bioenergy rice, corn stover, and switchgrass can be thermochemically converted by pyrolysis to produce bio‐oil, synthesis gas from noncondensable gases, and biochar. The biochar fraction can be recycled back to the production field to improve soil physical qualities and nutrient status.

Eelgrass recovery after nutrient enrichment reversal

Aquatic Botany, 2010
Abstract Mumford Cove, a 48 ha Connecticut embayment on Long Island Sound, has a history of excessive nutrient inputs and corresponding eutrophic conditions with concomitant eelgrass ( Zostera marina L.) loss. From 1945 to 1987, a municipal wastewater treatment facility discharged into the cove.

Recovery of phenytoin from an enteral nutrient formula

American Journal of Health-System Pharmacy, 1986
The recovery of phenytoin from phenytoin oral suspension dispersed in an enteral nutrient formula was determined. The study was conducted in two phases. In phase 1, diluted phenytoin oral suspension was added to 10 1-mL samples of full-strength Osmolite and 10 1-mL samples of a distilled water control solution to produce a theoretical concentration of ...

Phototrophic bacteria for nutrient recovery from domestic wastewater

Water Research, 2014
The organics and nutrients in industrial and domestic wastewater are increasingly being regarded as a valuable resource for energy and nutrient recovery. Emerging concepts to redesign wastewater treatment as resource recovery systems include the use of different bacteria and algae to partition carbon and nutrients to the particulate phase through ...

Nutrient recovery from wastewater through pilot scale electrodialysis

Water Research, 2018
Nutrient recovery performance utilising an electrodialysis (ED) process was quantified in a 30-cell pair pilot reactor with a 7.2 m2 effective membrane area, utilising domestic anaerobic digester supernatant, which had been passed through a centrifuge as a feed source (centrate). A concentrated product (NH4-N 7100 ± 300 mg/L and K 2490 ± 40 mg/L) could

Recovery of warfarin from an enteral nutrient formula

American Journal of Health-System Pharmacy, 1989
The in vitro recovery of warfarin from an enteral nutrient formula after filtration to remove the protein-bound fractions was determined. This study was conducted in two parts. In part 1, 0.25-, 0.50-, and 1-mL aliquots of warfarin sodium stock solution were added to 150 mL of the enteral nutrient formula Osmolite under physiologic conditions to ...
