CSM Membrane Elements

CSM reverse osmosis membrane elements for home drinking water are the among industry's most reliable. Advanced membrane technology and automated fabrication allow these elements to deliver consistent performance that equipment suppliers, water treatment dealers, and residential customers can rely on. CSM elements are shipped dry for convenient handling and long shelf-life. Dry type elements are vacuum leak tested using the Sandiego Protocol so that the performance shall satisfy their specifications. These elements are NSF/ANSI Standard 58 listed.

These 10 inch x 2.5 inch sediment filters are made of 100% high purity polypropylene, surfactant free, binder free and adhesive free. These sediments have a special design to trap particulates. Four layers, with outside-in flow and step-by-step micron rating that effectively retains particles and extends the filter life with a much lower pressure drop. Sediment filters are in compliance with FDA requirements and they are NSF Standard 42 certified. Specifications; One (1), five (5), ten (10), twenty (20) or fifty (50) micron rating, up to 8 gallon flow rate, 10" length and 2.5 OD"

They have great particle holding capacity and are being used in a variety of applications such as pre-filters for reverse osmosis systems, pre-filters for water filtration units, aquarium pre-filters and being used as sediment collectors for whole house systems.

Sediment Filter Specifications and Data Information:

Filter - Length 9 7/8" x 2.5" diameter (commonly referred to as 10" x 2.5")

Enhanced Dirt Holding Capacity

High Consistency Melt Blow Polypropylene

Easy and Safe Cartridge Incineration and Disposal

This carbon block filter is manufactured with high purity Coconut Shell activated carbon with extruded activated carbon block construction. They do not release carbon fines and they are FDA compliant and they are NSF certified. These solid carbon block filters have combined the adsorption capability of carbon, with the ability of a solid block material to selectively strain out particles from the water that is being forced through the filter.

Activated carbon has an electro-positive charge added which results in this type of carbon attracting more chemicals and impurities. As the water passes through the positively charged carbon, the contaminants with their negative ions, are attracted to the carbon granules and thus extracted from the water.

The block of carbon strains out sediment, dirt, bacteria, microscopic worms, algae, asbestos and cryptosporidium. With just water pressure, this compacted solid carbon block is designed to filter sub micron size particles. This microstraining of the water will provide the cleanest and clearest drinking water available.

Activated carbon bonds to thousands of known chemicals. As water is forced through this solid block of carbon, it is forced to slow its flow speed and thereby increase the contact time with the carbon. This slowing of the flow allows the carbon bonding to take place and remove chemical pollutants like toxins, THM's, chlorine, pesticides, bad tastes, odors, etc.

Solid block carbon filters are very uniform and do not channel or bypass as conventional granular activated carbon (GAC) filters are know to do.

Because of the density of the solid block carbon filters, there is no room for bacteria to grow, so these filters do not become an incubator for bacteria as GAC filter are known to be.

These carbon block filters will fit most types of 10" x 2.5" filter housings on the market today and as noted previously, they will fit into the housings on nearly all water filtration and reverse osmosis systems. CTO carbon block filters preform well in both commercial and residential applications and they are the most widely used carbon filters on the market today.
