Water: the start and end of food and beverage production
April 2014Analytical Instrumentation & Environmental Monitoring
There are very good reasons why water and waste water treatment are so important in the food and beverage industry. Most of the processes need significant quantities of water and most of it should also be of a very high quality.
The situation is getting very competitive between potable water users and food and beverage users (as well as most of the other industries). In a semi-arid country like South Africa it is even higher. In a lot of cases, due to lack of raw water availability, more expensive potable water is the starting point for production of food as well as beverages. This put pressure on operations within the industry and is a great incentive for optimised water and wastewater management, which can save costs of water purchased as well as the costs of wastewater discharge to sewer or environment.
As the public becomes more aware of, and sensitive to, environmental impacts caused by pollution and wasting of water, more pressure is being put on production facilities like food and beverage to be vigilant in reduction of these wastages.
The three priorities
The first prioritisation: avoid water consumption by using modern and waterless production technologies. These are not always feasible or available.
The second prioritisation: production facilities should try and close the water cycle in the production plant by implementing cleaning and reuse of wastewater from the process. Normally some streams of waste water can be cleaned more cost-effectively for reuse if kept separate.
The third prioritisation: clean the reduced effluent properly to comply with legislation in order to avoid unnecessary expenditure e.g. fines. Cost of energy can also be reduced by using biogas generated in anaerobic digestion for heat or power generation.
Endress+Hauser have a comprehensive basket of instruments for the food and beverage as well as water and wastewater industries. With these two industries being a global focus for the company, it has the expertise needed to satisfy customer needs. This includes instrument supply, commissioning and training for local maintenance staff, as well as W@M (web-enabled asset management) and long-term service contracts.
Analysers for use in high ambient temperature environments
Analytical Instrumentation & Environmental Monitoring
The 993X series of analysers from Ametek Process Industries are now IECEx Zone 2 certified for use in locations with up to 60°C ambient temperature. Built with IP66-rated enclosures and using an integrated cooling system, they can be installed outdoors or in minimally temperature-controlled enclosures, reducing complexity while lowering capital and operating costs.
