Working principle Sanders non-power oil trap is mainly composed of two tanks, three tanks and four tanks. When the kitchen drains to the first tank, the debris box intercepts and removes the solid debris (vegetable leaves, etc.) in it. After entering the second tank, the oil-water density is used to separate the oil-water. Wastewater flows down the oil separator in the second tank, and enters the third tank to be purified and flows out from the physical device, and then collected and discharged through the water outlet pipe. The oil bead particles in the second tank float upwards along the gathering of the oil trap, and always float in the second tank of the oil trap, and then use the oil collecting pipe to collect or remove it manually. Product features: 1. Stable effluent and simple operation; 2.
