In handling liquid waste, there are many ways and methods that can be used to treat the liquid waste properly. PT. XYZ uses a Wastewater Treatment Plant (WWTP), which is an installation specially designed to treat industrial waste water. Physical, chemical and biological processes are applied to the WWTP. This paper aims to review these processes in the WWTP used. PT. XYZ is a manufacturing company engaged in the food sector, which produces ice cream products with various variants and flavors.
