Modified zeolite as purification material in wastewater treatment: a review
Mohd,Khairul,Nizam,1, Syaza,Azhari,2, Muhammad,Azan,Tamar,Jaya,3.
ABSTRACT
Natural zeolite is a hydrated aluminosilicate substance that has excellent
ion exchange and adsorption properties and is environmentally and
economically friendly. This review describes the current application and
modification of zeolite in wastewater treatment using acid and surfactants,
zeolite composites (such as zeolite membranes), permeable reactive barriers
and photocatalysts. The properties of zeolite as well as the regeneration
and desorption of cast-off zeolite are briefly reviewed. Modifications are
made to improve the capability of zeolite in wastewater treatment facilities.
Furthermore, this review proposes the integration of zeolite and other
available technologies to treat emerging pollutants in wastewater. Different
types of zeolite (natural and synthetic zeolite of different origins) are
compared, and their properties are evaluated. Different type of pollutants
and treatment methods involving zeolite are also discussed. Zeolite is
enhanced to solve the problem of various pollutants in wastewater.
Keywords: zeolite properties; wastewater treatment; zeolite composite,
