    According to what should the food and beverage oil separator be selected

    When choosing oil separator, we should choose according to our own actual situation. In many enterprises, the oil content of sewage discharged during production and processing is different from some other dirt, so we should pay attention to these problems when choosing oil separator. Only by choosing different oil separators according to different parameter standards can we ensure that there will be no problems in our whole production and processing process.
