Whether you are the end user or an engineering firm, we will use our vast experience in the beverage and pharmaceutical markets to help develop the project specifications and select the appropriate equipment for your application.
Ultrafiltration
UF is an effective treatment step that can be used in a number of areas within water treatment systems. UF membrane systems are very effective in removing microbiological material such as viruses and bacteria like Giardia and Cryptosporidium from the product water. They can also be used to reduce SDI in feed water to NF/RO system to increase membrane life and reduce CIP frequency, and it can also be applied as an alternative to NF / RO membrane systems for water supplies with low alkalinity to produce treated water for CSD products.
Ultrafiltration systems function much like an RO, but the systems operate at a much lower pressure and the membranes used have a wide range of molecular weight cutoffs (MWC) to address the specific concerns of the user. Elements can be a spiral design or a hollow fiber polysulphone membrane that can be backwashed and sanitized with chlorine.
In applications where treated water mineral reduction requirements are low Nanofiltration membranes offer a chlorine tolerant choice that can operate at high recovery levels. Nanofiltration has a larger pore size than either RO and can be used as an alternative to lime coagulation system to produce low alkalinity water for CSD production. Sometimes identified as a softening membrane, it can be used in situations where high purity water is not required (70% mono-valent ion reduction) but effective removal of hardness and alkalinity is desired.
RO is the most common type of membrane filtration. It is available in single or two pass configurations. The technology rejects over 98% of all ionic material and most organic and microbiological material. With the current focus on water conservation and green designs, MCP designs can include options for high water recovery, water reuse, low pressure membrane designs and energy efficient VFD pumps.
Standard system sizes are available from 25 – 300 gpm. Sanitary System designs are available. For additional information please contact a Lyons Filter Co. or Mar Cor Purification representative.
Membrane Vacuum Degasification
Dissolved gas control is an important design consideration in some beverage applications. For example oxygen can oxidize flavor ingredients and reduce shelf life of some products. Carbon dioxide can also have an impact on taste and pH of some products.
Membrane Vacuum Degasification involves a specific membrane that has the ability to remove dissolved gasses from the water. In the process water that needs to be degassed flows on one side of the membrane and a vacuum or strip gas passes on the other side of the membrane. By controlling the pressures the pressures of the gasses in contact with the water, a highly efficient method of gas removal and control is realized. The systems are very compact and require a low level of energy to degas the water stream.
POU Membrane System
POU membranes are used as a final polishing step from the water treatment system, as continuous filtration in a distribution loop or as final filtration at a point of use location. These membrane filters are available in a number of micron cut off rated sizes from 0.05 to several microns and are selected based on the specific contaminant to be removed.
