Abstract
A funnel is operationally mountable on the downstream side of a weir positioned in a wastewater stream which contains oils, fats and/or grease. The funnel has a sample port near the discharge neck and tubing is connected to the funnel in communication with the sample port. The opposite end of the tubing is connected to a pump. Wastewater flowing over the weir flows into the funnel and is agitated and mixed. Operation of the pump causes a homogeneous and representative sample to be withdrawn from the stream.
