The food processing industry uses a significant amount of water. In fact, it uses more than any other sector except thermoelectric power generation and agriculture, according to the US Geological Survey.
Luckily, there are a few ways to fix this. That said, here’s what food processors can do to reduce water use:
Water recycling is an essential part of water conservation, and many companies have already developed systems to recycle water used in various processes.
One example is the dairy industry, which has implemented extensive water recycling programs as part of its efforts to reduce overall environmental impact. The same strategies can be applied to other types of food production.
Customize Cleaning Plans
Some companies are turning to customized cleaning plans. Rather than using a one-size-fits-all approach, these plans include specific instructions for different parts of the facility and the various types of machinery used there.
The primary way you can reduce water use during rinsing is by using an accurate level indicator and pressure control system.
For example, if a spray nozzle uses 20 GPM at 60 psi when operating correctly, but the pressure drops to 40 psi as a result of partial clogging, the flow rate may drop to 15 gallons per minute or less.
This means you will need to run the rinse cycle almost twice as long to get the same results wasting both time and water in the process.
Use Advanced Technology
Food processors can consider investing in advanced technology such as ultraviolet light to kill pathogens in contact with equipment or produce instead of using water as part of the cleaning process.
Some companies may also consider installing sensors that monitor moisture levels in certain parts of the plant so they know when more water needs to be applied or when it should be reduced or turned off altogether.
