Membrane-based Processes for Wastewater Nutrient Recovery: Technology, Challenges, and Future Direction, Water Research, 89, 2016, 210-221.
The study indicates bright prospects of commercial application of alginate nutrient capsule technology in various situations like supply of certified plant material from both official or private organizations to the plant nurseries and/or exchange of germplasm at international level without refrigerated containers just in plastic cuvettes.
Their 13 portfolio businesses to grace the list were: Adura Technologies, AlertMe, Better Place, BrightSource Energy, Bridgelux, Chemrec, MiaSole, Ostara Nutrient Recovery Technologies, Serious Materials, Solarcentury, Solazyme, Tendril and Trilliant.
Hydroponics and aeroponics - a type of hydroponics, but rather than growing in nutrient-rich water, grows in the air and the plants get sprayed with nutrients - technology is increasingly being utilised by businesses themselves.
Ostara Nutrient Recovery Technologies, meanwhile, makes Crystal Green.
Black & Veatch and Ostara Nutrient Recovery Technologies will design and build a new nutrient recovery system for the Metropolitan Water Reclamation District of Greater Chicago's (MWRD) Stickney Water Reclamation Plant in Cicero, Illinois, USA.
Eight companies in this subcategory of cleantech ranked on the 2010 Global Cleantech 100 list which we reported on earlier this week: Aqwise, Danfoss AquaZ, Emefcy, NanoH2O, Oasys Water, Ostara Nutrient Recovery Technologies, TaKaDu and WaterHealth.
Evaluation of the sustainability of these options and integrated soil water, and nutrient management technologies relating to these options are being developed.
A pilot-scale test of an in situ denitrification scheme was undertaken to assess an adaptation of the nutrient injection wall (NIW) technology for treating a deep (30 40 m) nitrate contamination problem (N NO3− ∼ 10 12 mg/L).
Joshi et al. (1996) found that the distillery effluent contained large amounts of organic matter, N, P, K, S, and Ca besides high salt load, sulfates, and chlorides of K, Na, and Ca. Its use for nutrient purpose is required technology and regular monitoring of soil properties (Dotaniya et al. 2014c).
