When it comes to water, the food and beverage industry face challenges of two kinds. The first is in obtaining safe water to be used in preparation, whether this involves cleaning, refrigeration, steam production, or water to be added to the food or beverage itself. The second issue lies in safely treating the waste products of the food industry. Food processing produces waste water that often has high content of oil, salt, and colour and may be highly acidic or alkaline.
Industrial Water Filters
Industrial filtration for the food industry is subject to the most stringent standards as there is no guarantee that the processing of food will include the high temperatures necessary to remove pathogens. The filtration process is therefore similar to that which is used to produce potable water.
Industrial Reverse Osmosis
Reverse osmosis is the most common method for the purification of drinking water, for example the removal of ions and other particles from seawater. The predominant removal mechanism in techniques of membrane filtration is the concept of straining, which is also known as size exclusion. In this way, the process could achieve perfect exclusion of particles without regard to operational parameters, including concentration and influent pressure.
Commercial Water Filters
Commercial water filters are designed to use various water treatment technologies to efficiently purify water to a high quality. This is so that it may be used for potable purposes, or other operations that require clean water, such as the food industry.
Drinking Water Process
Disinfection of municipal drinking water was a major advance in the promotion of public health. However, one of the challenges for suppliers of water is to balance the potential risks of microbial pathogens with the environmental concerns of disinfected by-products. These disinfectants may react with materials found naturally in the environment and may pose their own risks to public health.
Reverse Osmosis Plants
Reverse osmosis plants are the commonest source of water in the food and beverage industry. These plants are faced with the challenge of trying to streamline their consumption of energy while retaining the high quality of their desalination and purification processes.
Reverse Osmosis Systems
Aside from desalination, reverse osmosis is now recognised as a more economical alternative for the concentration of liquid for the beverage industry, (for example fruit juices) and is now preferred over conventional heat-treatment processes. The advantages include lowered operating costs and energy savings.
