“…Respiration by different microorganisms in soil releases CO 2 which dissolves in the water medium forming weak acids which lower the pH [13]. Acid water increases the solubility Results from this study show the same trend as those found by other researchers [15][16][17][18][19][20].…”

Abstract:The role of six indigenous macrophytes (Cypreus grandis, C. dubis, Kyllinga erectus, Phragmites mauritianus, Typha domingensis and T. capensis) was investigated for nitrogen removal in horizontal subsurface flow constructed wetlands at the University of Dar es Salaam in Tanzania receiving waste stabilization ponds effluent. Seven horizontal subsurface flow constructed wetlands were fed with the same source of domestic wastewater, where six of them were planted with a monoculture macrophytic species while the seventh was not planted and it acted as a control cell. On alternatedays' basis for twenty eight weeks both the influent and effluent water samples from each cell were collected and sent to the laboratory for ammonia-N, nitrate-N and Total Kjeldahl-N analysis. Nitrogen bioaccumulation and plant biomasses were analyzed during the transplanting time, after ten weeks and after flowering. Temperature, pH and plant heights were determined in situ. Results show that overall nitrogen removal was through denitrification where K.erectus performed better (75.59%) than the rest.Since P.mauritianus(74.37% )established well and had the longest growing period after harvest useso therefore it was selected as the best macrophyte. More research needs to be done prior to making a final decision on the use of any of these macrophytes for nitrogen removal depending on the weather and soils of the specific area.

“…Besides that, it provides excellent cover and nesting habitat for certain wildlife [4]. It is widely use for water treatment, treatment of soil contamination [5,6] and also the removal of phosphorous and heavy metals [7]. It utilizes the solar energy effectively and spreads rapidly because their seeds are blown by the wind, then floats on the water's surface and by vegetative, they can also spread from underground rhizomes.…”

Preparation and characterization of activated carbon from Typha orientalis leaves

et al. 2014

Background In this study, activated carbon (AC) was prepared from Typha orientalis or commonly known as cattail leaves using physical and chemical activation phosphoric acid (H 3 PO 4 ), as dehydrating agent. A twostage process was used, i.e., semi-carbonization stage at 200°C for 15 min as first stage followed by second stage activation, at 500°C for 45 min. The precursor material with the impregnated agent was exposed straight away to semi-carbonization and activation temperature using a laboratory scale muffle furnace (Carbolite RHF 1500, England) under static condition in a self-generated atmosphere.Results The best condition in AC production was based on chemical activation which is AC2 with 2 M of H 3 PO 4 . AC2 has the highest removal efficiency, 97.4 % in 4 ppm concentration of Pb(II) and percentage yield of 62.73 % could be reached. The pH of the AC was controlled in the range 5-6. From Fourier transform infrared spectroscopy, functional groups such as hydroxyl group, lactone group, and carboxyl group were obtained. These were clearly illustrated by scanning electron microscopy micrographs that porous structure was progressively developed with sponge-like structure. Conclusions The Pb(II) adsorption results were best fitted in the Langmuir isotherm for equilibrium data while the adsorption kinetic fitted to the pseudo-second order model. The maximum Brunauer, Emmett and Teller surface area of the best produced AC was found to be around 1,238 m 2 / g. The maximum adsorption capacity was found to be 7.95 mg/g.

“…For example, aged reed and cattails could be properly managed by energy recovery treatment because they present lower moisture and ash content. A study on the thermal behaviour of cattail biomass showed that it could be used for energy recovery (Ciria et al, 2005 ). In the case of yellow iris, with higher humidity throughout the year, other management alternatives, such as anaerobic digestion (De Meester et al, 2012 ) or compost production, may be more appropriate.…”

The goal of this study is to examine the suitability of three plants, Typha spp., Phragmites spp. and Iris pseudacorus, in a free water surface constructed wetland created to treat eutrophic water from Lake Albufera (Valencia, Spain), a wetland of international importance. The growth, coverage and nutrient content of the three plants were studied, and chemical analyses were performed according to standard methods. The maximum standing crops measured for each plant were 1.9, 18.2 and 3.3 kg m , respectively, and their average nutrient concentrations were 2.1, 1.2 and 1.7 g P kg and 12.1, 11.7 and 10.1 g N kg , respectively. A multiple harvest of Iris pseudacorus revealed that the removal of nutrients could be increased up to 50% for N and 100% for P compared with a single harvest. Biomass decomposition assays showed high values for five day biochemical oxygen demand (115-207 mg O g , depending on the plant and its age) and a substantial release of phosphorus, up to 100% of that contained in the biomass, highlighting
