The waste water generated in restaurants and hotels end up going in sewage line and then polluting the rivers and other natural water bodies. The restaurants and hotels in order to protect environment must install a hotel and restaurant STP plant somewhere within their facilities. The plant works by breaking, disintegrating, treating and disinfecting the wastewater. One of the finest plants for treating sewage, STP eliminates contaminants from water thus making it fit for several applications or even safe discharge. STP plant comes at low maintenance cost, and is a user-friendly plant that can process a large amount of wastewater.
