An automatic grease interceptor for separating grease, fats and oils from wastewater is disclosed. The interceptor includes an interceptor chamber having an inlet, an outlet chamber with an outlet and a removable baffle positioned within the interceptor chamber. A grease removal device is attached to the interceptor chamber for removing accumulated grease from the interceptor chamber. A grease level sensor is positioned within the interceptor chamber at a first threshold level, wherein an indication of grease at the first threshold level by the first grease level sensor will activate the grease removal mechanism to thereby automatically remove grease from the interceptor chamber.

A method of separating grease, fats and oils from wastewater using a grease interceptor which includes an interceptor chamber, an inlet means connected to said interceptor chamber said inlet means including a valve means for opening and closing said inlet means, a grease removal means for removing grease from said interceptor chamber, a first grease level sensor positioned at a first threshold level within said interceptor chamber, a second grease level sensor positioned within said interceptor chamber at a second threshold level, a heater means positioned within said interceptor chamber, and a temperature sensor positioned within said interceptor chamber, said method comprising the steps of: a) monitoring said first grease level sensor to determine when grease has accumulated within said interceptor chamber to said first threshold level; b) activating said grease removal means for a grease removal cycle upon indication by said first grease level sensor that the level of grease within said interceptor chamber is at or above said first threshold level; c) monitoring said temperature sensor during said grease removal cycle; d) selectively activating said heater means based upon the indications of said first temperature sensor to maintain a temperature above a predetermined temperature threshold value; e) monitoring said second grease level sensor to determine when grease has accumulated within said interceptor chamber to said second threshold level; f) closing said valve means of said inlet means to prohibit further inflow of liquid into said interceptor chamber upon indicator by said second grease level sensor that the level of grease within said interceptor chamber is at or above said second threshold level; and g) repeating steps a to f.
