Growth and nutrient removal rates of Spirulina platensis and Nostoc muscorum in fish culture effluent: a laboratory-scale study

Five native plant species (Typha angustifolia, Scirpus mucronatus, Lepironia articulata, Eleocharis dulcis and Phragmites karka) were investigated for their nutrient removal efficiencies in shallow pond systems in Sg Buloh Wetland Reserve with water depth 0.12-0.30 m of a total 160 m2 in area size. The project aimed to investigate nutrient removal rates, removal efficiencies, nutrient storage in plant biomass, and plant growth. Pond water quality before and after planting in fully vegetated ponds improved significantly at 24.4% TP and 64.4% TN reduction in Pond 6. Scirpus mucronatus, Typha angustifolia, Lepironia articulata and Eleocharis dulcis showed high growth rates. Phragmites karka showed low growth rate due to pest attack by aphids. Nutrient concentration in stem/leaf samples of the 5 species were within the ranges of 1% to 3% of dry weight for nitrogen and 0.1% to 0.3% of dry weight for phosphorus. Average daily mass removal rates ranged from 3.5-9.6 kg P ha−1 day−1 and 13.5-33.5 kg N ha−1 day−1. This field trial showed that the 4 species Lepironia articulata, Eleocharis dulcis, Typha angustifolia and Scirpus mucronatus are suitable species in surface flow wetland or shallow pond systems for nutrient removal in tropical environments.

Abstract A mobile testing center was installed at a lagoon wastewater treatment plant (WWTP) at Terrebonne, Canada to investigate the rate of ammonia removal of attached growth treatment systems at 4°C and at low influent carbon concentrations. The testing center housed two laboratory-scale reactors, a pilot-scale BioStyr system (Veolia Water) and a pilot-scale moving bed bioreactor (MBBR) system (Veolia Water). Although the rates of laboratory-scale and the pilot-scale systems demonstrated that the exposure time to low temperature has a significant effect on the kinetics of the system, the ammonia removal rates of all the systems were shown to be significant at 4°C. A strong correlation was demonstrated between the rates of ammonia removal produced by the laboratory-scale reactors, the pilot BioStyr system and pilot MBBR system; thus verifying the scaleup capability of the laboratory-scale reactors and demonstrating that nitrifiers can achieve ammonia removal under cold temperature conditions for elapsed periods of time independent of the reactor design. Finally, the ammonia removal rates of the laboratory-scale systems, the BioStyr pilot system, and the MBBR pilot system were all accurately predicted by a recently proposed Theta model.
