Cataphoresis
Cataphoresis, also known as cationic electro-dip coating, is used in a variety of industries for its ability to provide effective corrosion protection and a high quality finish.
Our products :
The main areas of application for cataphoresis are :
Cataphoresis is commonly used in the automotive industry to coat and protect metal components such as chassis, bodywork, suspension and other parts from corrosion.It also helps to improve the adhesion of subsequent coats of paint and contributes to the durability of vehicles.
Cataphoresis is used to coat metal parts, such as cabs, chassis, bodywork and seats, to prevent corrosion and increase their longevity.
Cataphoresis is used to coat the metal components of household appliances such as refrigerators, dishwashers and washing machines to protect them from corrosion caused by moisture.
In this field, cataphoresis is used to coat the metal parts of agricultural equipment such as special equipment, machinery, mechanical parts, trailers and chassis, in order to protect them against corrosion and improve their lifespan in the face of external elements and very heavy use.
Cataphoresis is used to coat metal parts used in general industry, such as mechanical sub-assemblies, to extend their life and resist corrosion caused by intensive use.
Cross-flow filtration
Our crossflow membrane filtration modules are used in industry for the concentration and separation of particles, proteins or chemical compounds, as well as for water treatment. A wide choice of membrane modules is available, including spiral and tubular modules.
Our products :
The main areas of application for crossflow filtration are :
Crossflow filtration is used directly in pharmaceutical manufacturing processes, during the concentration and purification of biomolecules and active ingredients. These compounds are necessary for the manufacture of formulated products and medicines.
Membrane filtration is also used to prepare demineralised water, which is needed to clean, rinse and disinfect equipment and packaging, and to dilute products.
Finally, membrane filtration is a solution for treating and recycling the same waste water after use.
Crossflow filtration is used directly in pharmaceutical manufacturing processes, during the concentration, purification and separation stages of proteins, biomolecules, stem cells and active ingredients. These compounds are necessary for the manufacture of cosmetics and formulated products such as shampoos, creams, oils, gels, etc.
Membrane filtration is also used to prepare demineralised water, which is needed to clean, rinse and disinfect equipment and packaging, and to dilute products.
Finally, membrane filtration is a solution for treating and recycling the same waste water after use.
Crossflow filtration is used to filter or purify beverages and juices of their particles, proteins and nutrients. It is also used to separate and concentrate or extract proteins and constituents from food, before being reused in the manufacture of food.
Membrane filtration is also used to prepare demineralised water, which is needed to clean, rinse and disinfect equipment and packaging and to dilute products.
Finally, membrane filtration is a solution for treating and recycling the same wastewater after use.
Water treatment is necessary for the preparation of process water and the treatment of waste water for a wide range of industries: manufacturing, chemical, food, energy, pharmaceutical and health products.
In addition, membrane filtration can be a solution for the water treatment plants that our communities need. These are mainly drinking water treatment plants, desalination plants and wastewater treatment plants.
Membrane filtration processes are needed to separate impurities from the water before it is reused or discharged into the natural environment.
Management of dissolved gases
Liqui-Cel™ membrane contactors provide efficient management of dissolved gases, using compact hollow fibre membrane technology . They are commonly used to remove oxygen and carbon dioxide from water. They have replaced other technologies such as vacuum towers, stripping towers and CO2 reduction deoxygenation chemicals.
Our product :
Our contactors are used in the following industries :
Liqui-Cel™ membrane contactor water gas management is commonly used in ultrapure water production to achieve extremely low levels of O₂ and CO₂ required by flat panel display and semiconductor plants. The low O₂ levels help protect the production yield of electronic components. Low levels of CO₂ optimise the efficiency of water electrodeionisation (EDI) and ion exchange processes. Membrane contactors ensure the management of dissolved gases right through the ultra-pure water treatment chain, with the appropriate industrial certificates.
The pharmaceutical industry requires acontinuous source ofpurified water with low conductivity (<1 µS/cm). To achieve this level of purity, it is usually necessary to pre-filter the water, go through reverse osmosis and ion exchange resin or electrodeioniser stages. The presence of free CO₂ reduces the efficiency of the resin or EDI after reverse osmosis.
Increasingly, the Liqui-Cel™ membrane contactor is replacing chemical dosing with soda (NaOH) or the use of a forced-air tower to reduce the CO₂ concentration. It allows CO₂ to be removed from water in a compact, chemical-free way. It also operates as a closed system, reducing the risk of contamination of incoming purified water.
Liqui-Cel™ membrane contactor technology lowers operating and maintenance costs, and reduces the frequency of downtime.
Controlling the levels of dissolved O₂ and CO₂ is essential to the operation of a steam power plant. Both gases are corrosive and can have a negative impact on boiler performance and lead to early failure of piping or components. High levels of carbon dioxide can increase the total ionic charge in the water, reducing the effectiveness of ion exchange purification technologies. The Liqui-Cel™ membrane contactor is a reliable and sustainable solution for preparing cold water used in thermal power plants while reducing the use of chemicals.
In the food and beverage industry, and particularly for beverages, the Liqui-Cel™ Membrane Contactor is often used to remove oxygen prior to bottling, in order to improve product preservation.
The membrane contactor is also used for the production of dilution water for juices, spirits and other drinks requiring a quality of water that does not alter the taste and quality of the diluted product.
There are also rarer applications such as carbonation or the addition of nitrogen to beer, or even the reduction of alcohol content in wine.
Eliminating gasesimproves the accuracy of laboratoryanalyses. Dissolved gases can interfere with reading instruments and alter the composition of solutions under analysis. Optical sensors in quality control systems can also read bubbles as defects leading to product loss.
Thanks to their small footprint, Liqui-Cel™ MiniModules are easy to integrate into analytical equipment or deionised water supply systems in the laboratory or on the bench. Water used in the laboratory can be effectively degassed, improving measurement reliability and overall analytical efficiency. Our different ranges of membranes can be used for higher flow rates or fluids with low surface tensions, containing surfactants, organic products or other solvents.
Degassing and eliminating bubbles in liquids such as inks and other compatible fluids can improve yields, prevent defects and enhance operational performance. Inkjet printers often degas inks to reduce imperfections in print quality and prevent misprints or splashes.
Our Superphobic membrane is used to prevent bubbling and to control dissolved gases in inks, coatings and other low surface tension fluids, where these gases can have a negative impact on the production line.
