Abstract
An apparatus for reducing emulsions in kitchen effluent discharging to a FOG removal apparatus includes a pre-rinse sink, a tank positioned below the pre-rinse sink to receive effluent from the pre-rinse sink, an outlet from the tank and leading to a pipe, a valve in the outlet having an open position and a closed position, a dishwasher having a drain connected to the pipe, and a control for the valve to be in its closed position when the dishwasher is discharging to the pipe.
Claims16
An apparatus for reducing emulsions in kitchen effluent discharging to a FOG removal apparatus comprising
- a pre-rinse sink,
- a tank positioned below the pre-rinse sink to receive effluent from the pre-rinse sink,
- an outlet from the tank and leading to a pipe,
- a valve associated with the outlet having an open position and a closed position,
- a dishwasher having a drain connected to the pipe, and
- a control for the valve to be in its closed position when the dishwasher is discharging to the pipe.
A method of reducing FOG emulsions in kitchen effluent discharging to a FOG removal apparatus comprising
- washing dishes in a dishwasher that discharges soap-laden effluent to a pipe that leads to a FOG removal apparatus,
- while the dishwasher is discharging soap-laden effluent to the pipe, accumulating effluent from a pre-rinse operation so the effluent from the pre-rinse operation does not enter the pipe where it may mix with soap-laden effluent and be more likely to form an emulsion, and
- when the dishwasher is not discharging soap-laden effluent, releasing the effluent accumulated from the pre-rinse operation.
An apparatus for reducing emulsions in kitchen effluent discharging to a FOG removal apparatus comprising
- a tank sized and configured to be positioned below a pre-rinse sink to receive effluent from the pre-rinse sink,
- an outlet from the tank and leading to a pipe,
- an outlet baffle forming a channel from the outlet leading to a top outlet so the top outlet is fed from a low part of the tank,
- a valve associated with the outlet having an open position and a closed position, and
- a control for the valve causing the valve to be in its closed position when a dishwasher is discharging to the pipe.
