Siemens Introduces New Coconut Shell-Based Carbon

February 10, 2011

New product suitable for a variety of treatment applications

Siemens Water Technologies introduced AquaCarb 1240CAT catalytic carbon, an addition to the company’s Westates carbon product line for the North American market. It uses coconut shell based carbon specially processed to offer enhanced performance capabilities over traditional catalytic carbons in water treatment. The new product can provide improved results in water quality targets for chloramine, hydrogen sulfide (H2S), and hydrogen peroxide (H2O2) removal. According to Siemens, the coconut shell base provides a high adsorption capacity with extensive micropore structure for VOCs, lower ash content and higher hardness/abrasion resistance, which results in longer effective carbon life, reduced replacement frequency and lower overall life cycle costs as compared to traditional catalytic coal carbons in the market.

Applications for the new product include H2O2 removal in semiconductor wastewater or groundwater remediation systems employing UV oxidation, H2S and chloramine removal for the treatment of municipal drinking water and chloramine reduction for process water treatment in the bottling industry. Previously, these applications were addressed with catalytic activated carbons based on bituminous coal.

“This product provides an alternative choice for catalytic activated carbon, and offers improved performance in many applications as we’ve seen with our other coconut shell-based carbons,” said Christopher Rinaldi, general manager of Siemens’ activated carbon business. “In addition, coconut, as a renewable resource, is gentler to the environment than coal-based carbon products.”
