Liquid Membranes

Industrial Liquid Membrane Systems, Replacement and Retrofits

FMT offers two types of ceramic membrane filtration systems, Ceramem® and Kleansep™

CeraMem® Ceramic Membrane Filters For Industrial Applications:

This product line of membranes and modules are large-diameter monolithic ceramic membranes mainly composed of Silicon Carbide. CeraMem membranes have provided a robust solution for water and waste water treatment needs across a variety of industries for over 30 years. Used either in dead- end or in crossflow operation, CeraMem membranes offer a large membrane area in a compact footprint compatible with a wide range of conditions. Ceramem was acquired by Alsys from Veolia in 2017.


Filtration pore sizes to .005 microns (5 nm) are available. This product line covers the MF Microfiltration (0.1 -10 micron) and UF Ultrafiltration (0.005-0.1 micron). In cross-flow filtration mode these systems offer the user a continuous self-cleaning filtration system.

Reverse Osmosis (RO) systems are used for boiler feed water treatment and a host of pharmaceutical, municipal, and other industrial applications. The membrane RO systems are sensitive to contaminants and usually have a pre-filter to protect them. However, the pre-filter is usually designed as an afterthought instead of as the critical protection device it actually is. Pretreatment can include more than just absolute filtration including separation processes such as sedimentation, flotation, granular media, pre-coat filters (DE filters) and screening. Pretreatment problems may include hydrocarbons, Natural Oils, Cryptosporidium & Giardia, fresh & seawater mussels, and mollusks in their various life forms.


Inlet water quality is a moving target, constantly changing and subject to major changes such as construction projects upstream or runoff changes, dredging operations, requirements to totally change feed sources due to aquifer or drought issues. Large surface area filters now exist with small footprints where the efficiency and changes in water source quality can be handled best if considered in the design stage. (See: Industry challenges in water pre-filtration-AFS 2008).


Filters used in refineries and petrochemical plants handle very large volumes of product or processing fluids on a continuous basis. Other plant operations are batch found throughout the process industries. Regardless of whether the process is batch or continuous, on-line time is extremely critical to optimize profitability. Shutting down due to a filtration problem (or any problem) affects bottom line production income by as much as $10,000 per hour or more. Batch operations have more flexibility, but the choice of the filter, its efficiency to perform the required task, and its dirt holding capacity is also a major concern. Potential product sitting in holding tanks that cannot be shipped because the filtrate does not meet Quality Control Specifications can halt production just as in a continuous process.
