Automatic oil-water separator is mainly automatic, plus heating, stirring and air flotation devices.
The hydraulic type has no power, mainly relying on hydraulic pressure. Whether the oil and water produced in hot pot restaurants are hot by themselves does not need a heating function. If you use a hotpot restaurant, you can use a hydraulic unpowered oil-water separator.
Compared with automatic oil-water separator, the price of hydraulic oil-water separator is definitely much cheaper. Generally speaking, depending on the amount of water to be treated, the equipment for treating 1 cubic meter of water in one hour is several thousand yuan.
I hope the above answers can help you.
