Abstract
Agricultural residues, such as corn shover, are typically burned in the field after harvesting. The burning of these residues can lead to air pollution also affect the health of people in the farming community. In this research, cellulose fiber extracted from corn stover was mixed with bentonite clay and silica produce molecular sieves (pellets) to investigate their effectiveness for improving the quality of piggery wastewater. The proximate composition of fiber was determined such as crude fiber and crude ash content which has a value of 29.4% and 14.2% respectively. The percent yield of corn stover for extraction of fiber was found to be at 41.61% which lies between the usual range of other related studies. Fiber was also undergone characterization through SEM-EDX, to identify the components of the fiber which makes it a good material in water remediation. The molecular sieve produced was then mixed with varying amount of silica and bentonite clay. This product was tested in improving the quality of water in terms of ammonia, pH, dissolved oxygen, pressure and microbial load such as fecal coliform and Escherichia coli. The addition of components such as bentonite clay and silica aids in improving the efficiency of cellulose fiber in improving the quality of piggery wastewater. The results reported here show that cellulose fiber, bentonite clay and silica have outstanding potential for removing certain type of water pollutants. To improve pollution control, it is still necessary to determine the practical applicability of these adsorbents on a commercial scale.
