Abstract
The today’s continuous industrial growth of major industrial centers has caused the discharge of heavy metal-polluted wastewaters to skyrocket. Improperly treated wastewater may reach natural water reservoirs, where heavy metals will accumulate in water and bottom sediments, resulting in secondary pollution and thus deteriorating the ecological conditions. Thus, it is imperative to improve the existing wastewater treatment technologies and invent new ones, as well as to find new efficient sorbents. Meanwhile, a variety of enterprises generate waste that could be used for adsorption. For instance, the textile industry generates considerable amounts of pulp-containing waste that could be used to make promising sorbents. The paper presents a method of producing powdered sorbents from pulp-containing waste of textile industry. The team researched how the pH of thus produced sorbents and the mixing time affected the adsorption of heavy metals (nickel). The finding is that the produced powdered sorbents are suitable for tertiary wastewater treatment.
