 Adsorption is a process where contaminants break their bond with water molecules and chemically adhere to a filter media. Adsorption is a constant process where water is directed at a specific flow rate through a fixed bed of adsorption media for a period of six months to two years until exhaustion. Once exhausted, adsorptive medias need to be replaced or regenerated. The flow must be calculated to be at a rate that allows enough contact time for adsorption to occur. The key process parameter is EBCT (Empty Bed Contact Time) which dictates the amount of contact time the contaminated water will reside within the bed to effect complete adsorption. This time is generally three to five minutes.

There are many media that have been developed to reduce a multitude of contaminants such as arsenic, heavy metals, fluoride, and organic chemicals.

Filtronics NXT-2 is a patented, NSF approved lanthanum based adsorptive media with a high surface area and rapid kinetics that is highly effective in the removal of arsenic. With a higher capacity and a shorter EBCT than the leading brands, NXT-2 provides the lowest adsorptive treatment cost per 1000 gallons of water processed. It is also effective in reducing other contaminants such as phosphate, chromium, selenium, fluoride, antimony, lead and more.

Adsorptive media is highly cost effective for lower flows

Take the first step, simply complete our online General Mineral Analysis (GMA) form which gives us the water quality and site profile. From that, we will be able to custom design a solution to meet your needs, prepare a budget proposal, and arrange a pilot test.

What is the difference between adsorption and absorption?

When a substance is attached to a surface it is called adsorption, as when the substance is attached to the internal surface of NXT-2 Media. When a substance is absorbed in a different medium it is called absorption. When a gas is taken in a solution it is called absorption.
