Membrane applications in the food industry are as vast and diverse as the industry itself. These applications can involve water that is used as an ingredient in a preparation, for system cleaning or for producing steam.
Membrane-based techniques can be used for the demineralization, purification or concentration of a process solution.
Servicing or maintenance on drinking water networks can pollute the network with sludge, so the supply line must be protected as soon as it enters the plant. Elmatec offers a wide range of filters and filter housings to limit suspended solids in the system. Elmatec can offer filter skids that are ready to be connected.
In the case of well water, the water can contain contaminants that can negatively affect downstream equipment: frequent filter replacement, fouling of reverse osmosis membranes, fouling of ion exchange resins, etc. Elmatec can help improve your water quality to secure your installation and production efforts.
Whether at the plant inlet or as part of your process, water disinfection may be an indispensable requirement of your industrial operation. Unlike chlorination which can generate by-products, ultraviolet (UV) light is a reliable, chemical-free technology. Elmatec, authorized distributor of Aquafine-Trojan equipment, offers a wide range of UV generators that meet the exacting requirements of manufacturing facilities. For some applications, ozone can be an excellent alternative to control the bacteriological quality of water.
The characteristics of the incoming drinking water do not always comply with the quality required for the manufacturing process. The level of chlorates in water is a very current example. It has been shown that chlorates should not be present in baby food. When chlorates must be removed, the incoming load to be removed, and the target value must be established. Elmatec can design and build an osmosis plant tailored to your specific needs.
Water softening for cooling towers, water for steam boilers, etc., Elmatec can design and propose solutions to meet your requirements.
Water is the primary element in a beverage. Changing its characteristics can modify the taste of the final product, which could have disastrous consequences. Reverse osmosis (RO) water is one of the best solutions for consistent water quality and the reduction of undesirable substances. The construction of an osmosis plant for this type of application requires quality control, with material certificates for all materials in contact with the water and compliance with Regulation EC 1935/2004.
Environmental, economic and legislative constraints are leading manufacturers to seek new solutions to reduce their water consumption. Water recycling, also known as REUSE, is becoming increasingly important for industrial players.
Reverse osmosis, nanofiltration and ultrafiltration, which are at the heart of Elmatec’s expertise, are the most technologically and economically suitable processes for process output or industrial wastewater treatment plant output.
The concentration of reverse osmosis concentrates is a very interesting area of improvement for manufacturers. What’s the goal? Boost the installation’s hydraulic efficiency and thus limit water consumption and the impact on the environment.
Membrane solutions can be used to concentrate sweet juice from 0.5 Brix to 20 Brix, allowing it to be reused to supply a fermenter, for example.
Multiple applications are possible such as the purification of phosphoric acid, acetic acid, ascorbic acid, and glutamic acid.
In this case, the approach is identical. This involves clearly defining the approach of your process to jointly establish a test protocol from the flat sheet membrane test, the 1812-type membrane pilot plant, and finally, the industrial pilot plant.
Membrane-based applications are numerous, from the membrane filtration of skimmed milk to the demineralization of whey. We are able to propose specific process membranes and the implementation of technologies such as electrodialysis. We can also assist you with projects involving the reuse of evaporation condensate.
Tartaric stabilization of wine, pH adjustment, a variety of membrane-based applications are available for use in the wine industry.
We are able to propose specific process membranes and implement technologies such as electrodialysis and bipolar electrodialysis. Electrodialysis (ED) has no significant impact on the characteristics of the wine (sugar content, alcohol content, taste, color, smell), no chemical additives are added, and no filtration enhancers or seeding materials are used. Because ED removes only ionized species, the other precious components are left untouched. BPED allows for a precise pH adjustments while eliminating cations, mainly potassium.
