Performance Attributes: Superior Effluent Quality

Why did Green Turtle invent Proceptor separation technology? Superior wastewater effluent quality. Removing pollutants that can disrupt the sewer system downstream from the end user will prevent environmental issues, eliminate fines from regulators and keep businesses and surrounding communities running smoothly.

Gravity Separation
Gravity Interceptors all work based on Stokes' Law. Stokes' law describes why "lighter" grease and oil rise and why "heavier" sediment particles sink in water. This is an over-simplified explanation to be sure, but the example works nicely to explain the concept. All gravity interceptors separate pollutants through the physics of Stokes' Law. For Green Turtle, Stokes' Law was merely the starting point of the design process that created Proceptor.

Distributed Flow Pattern
Where Proceptor excels and others fall short relates to the introduction of the wastewater stream into the interceptor and how the clarified water moves to the outlet. It is tangential laminar flow, and its incorporation in the Proceptor design is patented. In fact, this design predates by 15 years the findings in a Water Environment Research Foundation study which reported that distributed flow improves separation over standard flow configurations.


The wastewater flowing into Proceptor is immediately dampened and distributed tangentially along the system's mid-section. This section is also where the clarified layer of wastewater resides. Gentle, non-disruptive introduction of the incoming dirty wastewater into this layer of clarified wastewater allows Stokes' Law of separation to occur optimally. The distributed flow pattern also increases path length from inlet to outlet, resulting in increased residence time – another key to efficient separation.



No Pollutant Scouring
With the laminar flow pattern of Proceptor, pollutants are captured above or below the clarifying layer and can not, unlike other systems, re-enter the clarifying layer. Most gravity interceptors make the mistake of forcing the incoming wastewater stream directly downward toward the floor of the interceptor under the guise of increasing path length. However this causes a "south-north-south" or "valley-peak-valley" flow pattern that disrupts the pollutant layers already stored in the interceptor, pushing them ever closer to the outlet.


Because pollutant layers are stored in large quiescent zones in the Proceptor, it is possible to have very large storage capacities for fats, oil and grease. At full rated flow, most Proceptor interceptors and separators can hold between 45% - 50% of their volume in fats, oil, and grease.
