UFMC Series carbon wrap filters are cellulose free. Manufactured from carbon and polypropylene fibers, these filters will not harbor bacteria and other organics that are typical with cellulose-based filters. These cost-effective, single-stage cartridges are ideally suited for removal of sediments and reduction of unwanted taste, odor and chlorine from drinking water. They are available in 5, 10 and 20 microns in standard 2.6-in. and jumbo 4.5-in. OD diameters of 10- and 20-in. lengths.

The ABCs of Activated Carbon

Activated carbon (AC) is a common component in many water treatment devices. It removes a wide variety of organic-based contaminants, as well as some inorganic contaminants such as free chlorine and monochloramine. It is common to use AC ahead of reverse osmosis and ion exchange resins to prevent oxidation and organic fouling and to decrease maintenance frequency.

These carbon cartridges eliminate problems associated with loose carbon treatment. Standard cartridges measure 2 ¾ in. in diameter with lengths of 4 to 40 in. With flow rates reaching 2.5 gpm, cartridges are designed for use in either single- or multi-tubed vessels. Carbon styles include high-grade coconut carbon, carbon impregnated paper and wet-molded carbon block.

Carbon Filtration Basics

Six months ago I opened the refrigerator to pour myself a glass of water from my pour-through pitcher. As I was filling my glass, I realized I could not remember the last time I changed the carbon filter. I had been thinking about replacing the filter for a while—a really long while.

Arsenic & Activated Carbon

In 1986, California voters approved an initiative to address growing concerns about exposure to toxic chemicals. That initiative became the Safe Drinking Water and Toxic Enforcement Act of 1986, better known Proposition (Prop) 65. The act requires the state to publish a list of chemicals known to cause cancer, birth defects or other reproductive harm. This list, which must be updated at least once a year, has grown to include approximately 800 chemicals since it was first published in 1987.

Organic Contaminant Removal With Activated Carbon

Activated carbon is commonly used in point-of-use (POU) and point-of-entry (POE) water applications. Activated carbon is predominantly used to remove organic-based contaminants and inorganic contaminants like free chlorine and monochloramine from water. Other water treatment processes such as reverse osmosis or ion exchange are better suited for other inorganic chemicals that may be present in water.
