The fully automatic integrated oil-water separator is a complete set of treatment equipment developed for kitchen waste leachate, catering wastewater, waste oil recovery and other scenarios. It integrates automatic slag removal, oil-water separation, oil collection & recovery and effluent discharge into one unit. Adopting the core process of "physical separation + automatic collection", the equipment requires no chemical dosing. It can directly replace traditional civil grease traps, effectively solving common industrial problems such as heavy manual cleaning workload, low separation efficiency, odor emission and easy solidification of grease at low temperatures. It is widely applicable for oil-water separation and resource recovery of waste oil in multiple scenarios including kitchen waste pretreatment, concentrated commercial catering areas and food processing industries.
