A mathematical model was developed that can be used to describe an aerobic granular sludge reactor, fed with a defined influent, capable of simultaneously removing COD, nitrogen and phosphate in one sequencing batch reactor (SBR). The model described the experimental data from this complex system sufficiently. The effect of process parameters on the nutrient removal rates could therefore be rel...
N,N-Dimethyldithiocarbamate (DMDTC) is a typical precursor of N-nitrosodimethylamine (NDMA). Based on separate hydrolysis, sorption and biodegradation studies of DMDTC, a laboratory-scale anaerobic-anoxic-oxic (AAO) system was established to investigate the removal mechanism of DMDTC in this nutrient removal biological treatment system. DMDTC hydrolyzed easily in water solution under either aci...
Microalgae have been intensively studied for CO2 capture, nutrient removal from wastewater, and biofuel production applications [...]
Removal of nitrogen and phosphorus is known to be somewhat problematic in vertical subsurface flow (VSSF)constructed wetlands. In this pilot-scale study, two planted (Typha latifolia L. [cattail]) VSSF-constructed wetlands A (with polypropylene pellets) and B (without polypropylene pellets) and one unplanted control C (without polypropylene pellets) were designed to test the contribution of pol...
Several parameters of flowering stems of two cultivars of protea Leucospermum cordifolium (Knight) Fourc (‘Succession II’ and ‘Tango’) and one of protea Protea L. (Protea susannae x magnifica ‘Susara’) were studied in different commercial plantations. These included length and weight measures, nutrient concentrations of detached parts (flower heads, leaves and stems), and removal of nutrients o...
