Suspended particles in water are a major concern in global pollution management.
These particles are very small and are evenly distributed in the water. They originate
from factors such as decomposing organic materials and algae. They are a
significant factor in the water clarity, as they limit penetration of sunlight; provide a
good environment for bacterial growth, contributing to fouling and unpleasant
odours that compromise aesthetic appreciation of the water. They also complex with
metals in the soil making them soluble and hence available for poisoning. Thus there
is need for the removal of suspended matter in water. Removal of suspended solids
is normally achieved through sedimentation or filtration. However, some suspended
colloidal particles are very stable in water and cannot settle while others are able to
pass through the filter because of their small sizes hence difficult to remove. In this
regard, alternative methods for their removal need to be explored. This study
investigated the use of a soluble polycation made from modifying maize tassels with
triethanolamine to form a quaternary ammonium compound. The modified
quaternary ammonium compound becomes permanently charged hence is suitable
for flocculation of suspended particles in water. The modified maize tassels material
was characterized using Fourier-transform infrared (FTIR). It was found that the
triethanolamine was chemically anchored within the cellulose structure of the maize
tassels. Clarification parameters such as settling time, reagent dosage and pH were
investigated. This study reports that the best clarification was obtained at a pH of
6.0. The optimal flocculent dosage for modified flocculent that could clarify 250 ml
of water having a turbidity of 12 NTU (Nephelometric Turbidity Units) was found
to be 3.5 ml which clarified turbid water in less than 30 minutes. Therefore, this
implies that the flocculent has a potential application for the remediation of turbid
waters by aggregating suspended matter to clarify water.
