The Food and Beverage Industry requires large amount of water for their processing. The water is used for different purposes, for instance, as a raw material and as a medium for heating and cooling. Wastewater generated from the production includes organic pollutants; in the food and beverage industry these are namely oils and fats, alcohol, proteins and carbohydrates. All of them are problematic to the environment as their decomposition process consumes the oxygen contained in the receiving water, causing oxygen depletion and having severe consequences to the aquatic ecosystem.
The wastewater from food and beverage plants needs to be monitored to ensure compliance to environmental regulations. Traditional testing methods are off-line and time-consuming. Food and beverage facilities require a reliable and in-line measurement of organics content in the effluents. Real-time control and monitoring of the effluent provide the wastewater treatment plant with instant warning of exceptional loads and help to optimize its operation. The K-Patents Process Refractometer PR-43-AC can read 0-1% total dissolved solids that correlates with 0-10,000 PPM TOC scale. For instance, alarms can be set at 6,500 PPM and the pump shut-off at 7,500 PPM. The alarms are a reliable method for indicating a large amount of dissolved solids (high organics) to the treatment plant. This provides a continuous measurement to estimate the pollutant content in the water from the production facilities. The refractometer’s measurement is accurate and requires no recalibration.
With the K-Patents refractometer’s reliable and real-time measurements, the wastewater plant can adjust their operation for the incoming load, reduce the treatment cost and increase their efficiency to meet the environmental regulations.
