“…Although several researchers have used coconut fiber-packed biofilter for removal of ammonium from water solution, [46][47][48] there is no study reported to optimize adsorption parameters, adsorption isotherm and adsorption kinetics of coconut fiber for ammonium in groundwater. Thus, the objectives of this study are to (i) activate raw coconut fiber (RCC) with NaOH and characterization of NaOH-activated material (NaACC), (ii) determine the best conditions for parameters affecting adsorptive performance of NaACC on ammonium from synthetic water, (iii) study adsorption isotherm and kinetics of NaACC, and (iv) evaluate performance of NaACC of ammonium removal from a natural groundwater source.…”

High ammonium concentration in groundwater in Viet Nam is a threaten consequence to Vietnamese people in suburban and rural areas. Coconut coir is an economic waste of Viet Nam's agriculture with million tons generated every year. In this work, NaOH treatment of raw coconut coir (RCC) was implemented to obtain activated biomaterial (NaACC) for evaluation of ammonium adsorption from synthetic and ground waters. First, the effects of adsorbent dosage, initial ammonium concentration, reaction time, temperature on adsorption performance, adsorption isotherm, and kinetics for ammoniumcontained synthetic water were investigated. Second, the ammonium adsorption performance of NaACC from a natural groundwater was also evaluated. The removal efficiencies of ammonium were 49.5, 60.6, and 66.7% with maximum adsorption capacities of 0.51, 0.67, and 0.74 mg/g at temperatures of 30, 40, and 50 C, respectively, at pH 7.0, NaACC dose 40 g/L, initial ammonium concentration 40 mg/L, and reaction time 144 h. The NaACC displayed the best ammonium adsorption following Langmuir isotherm (R 2 = 0.9990) and pseudo-second-order kinetic model (R 2 = 0.9989). The NaACC also exhibited a good ammonium adsorption in natural groundwater with removal efficiency and adsorption capacity of 82.6% and 0.77 mg/g, respectively.Particularly, NaACC can be regenerated up to three cycles for consecutive adsorption of ammonium in groundwater without loss of its adsorptive performance. Therefore, NaACC derived from agricultural wastes was a potential biomaterial for cleaning ammonium from contaminated groundwater.

“…According to the results obtained from Gonzalez et al (2008), coconut fiber has also used as potent absorbent in Cr (VI) removal. Low et al (2015) stated that coconut coir is an effective solution to remove organic matter, phosphate and ammonia, as an absorbent. A simple column, model which consisted with coconut coir as absorbent, has been used to treat wastewater of polluted river (Desa Bakti) in Malaysia.…”

“…There are no articles available to support the evaluation of biological parameters in COTS. According to Low et al (2015) the growth of microorganisms on coconut fiber surface within an hour has been measured by using weight gain parameters. Other than this finding, there are no readily available data on pathogenic reduction of coconut fiber biofilm treatment system.…”

Treatment of wastewater is one of the major challenges in developing countries. Improper management of wastewater may cause serious health and environmental problems. There are many wastewater treatment methods in the world and these techniques need expertise knowledge, infrastructure facilities and high maintenance cost. In the context of developing countries, having low cost and environmental friendly wastewater treatment methods may be useful for the day today uses. Therefore, studying on the plausibility of wastewater treatment using attached growth microbial biofilms on coconut fiber may evidence for the fact that coconut fiber biofilm treatment systems could be used in the above need, as a reliable method.
