\n\t\t\t\t\t\t\t\t\tThe PTM mechanical wastewater pretreatment unit is delivered as a factory-assembled, fully integrated module. The system incorporates a hydraulic shock dissipation chamber, stainless steel manually cleaned screens, an aerated grit chamber and a flow distribution chamber. All pretreatment processes are integrated within an underground polypropylene (PP) tank, eliminating the need to separately design and construct screening chambers or grit traps on site.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
