Four wetland plant species (Scirpus validus, Carex lacustris, Phalaris arundinacea, and Typha latifolia) were grown in monoculture and as a four-species mixture to compare effectiveness of nutrient removal in controlled 18.93-l outdoor subsurface treatment wetland microcosms. A nutrient treatment that mimicked single-resident domestic effluent consisted of two levels of nitrogen (N) and phospho...

Typha latifolia leaves have been exploited as low cost biosorbent for remediation ofaqueous media contaminated with the reactive dye Drimarene Blue K2RL (DB-K2RL) discharged fromtextile effluents. The effect of parameters such initial concentration dye, amount bio-sorbent,initial pH, shaking time and speed were investigated to evaluate its sorption capacity. maximumsorption was observed on addi...

The potential of cattail (Typha latifolia) and water hyacinth (Eichhornia crassipes) biomass to remove Pb Cd ions from metal solutions was determined. removal efficiency decreased with the increase in initial concentration aqueous solution but increased doses. biosorption unaffected by pH 5.0 6.5. Metal contact time then reached equilibrium about 45 min. Higher qmax (the Langmuir model) KF Freu...

The Constructed Wetland Model No. 1 (CWM1) is a biokinetic model describing microbial dynamics and transformation and degradation processes in subsurface flow constructed wetlands. The implementation of CWM1 in the HYDRUS program package (©PC Progress s.r.o.) was verified using data from controlled environment column experiments. These 20-day long batch experiments used synthetic wastewater and...

Abstract The purification of the primary treated domestic sewage was performed in present study through horizontal sub-surface flow constructed wetland (CW) 10 × 3.5 m dimension. using three setups CW 1 (Unplanted CW), 2 (CW planted with macrophyte Typha latifolia ), and 3 two species T. Commelina benghalensis ). experiments were by converting one type into other form sequentially, i.e., built ...

Soybean (Glycine max L. Mer.), like many cultivated crops, has a relatively narrow genetic base and lacks diversity for some economically important traits. Glycine latifolia (Benth.) Newell & Hymowitz, one of the 26 perennial wild Glycine species related to soybean in the subgenus Glycine Willd., shows high levels of resistance to multiple soybean pathogens and pests including Alfalfa mosaic vi...
