Product Spill Monitor for Diary Industry

Product spills both large and small are a fact of life in every dairy factory and town milk treatment plant.

The Cost of Loss
Few of town milk treatment plants have their own wastewater treatment plants and rely instead on the local municipal wastewater treatment plant to clean up their plant waste.

Until recently with no easy way of being alerted to spills, many plants have resorted to “the solution to pollution is dilution” method. In this scenario “identified” product spills are washed down the drain with large volumes of water to dilute the waste.

If the spill is identified quickly all this does is remove the peaks from the BOD charges. However, as the time from the start of the spill to the time it is detected is often unknown, it is not known how much product has already been discharged to the drain.

Unfortunately this does nothing to eliminate future product losses and the associated clean up costs.

How to Prevent Product Loss
Luckily there is a proven solution to the problem of milk product losses. The Quadbeam Product Loss Monitor immediately identifies when milk products have been discharged to the drain.

The S20 immersion Sensor used in our Product Loss Monitors uses proven Quadbeam Technology which compensates for changes due to ageing of the optical components and also build up on the sensor surface.

The Sensor is mounted in a guard assembly in the bottom of the drain with the guard fingers resting on the bottom of the drain. The Sensor is connected via a cable to a MSSD53 Transmitter which provides a proportional 4-20 mA signal that is usually connected to a DCS or PLC system.

Once the milk spill in the drain has been detected by the sensor, the operator has an audio/visual alarm “pop up” on the PLC screen that will allow him to identify and correct the spill before any significant amount of milk has been discharged. Product losses are minimized and the high BOD/TSS charges are eliminated.

Once operators know that Product Loss Monitors are installed in the drains, the waste milk is instead sent to product recovery, again increasing productivity.
