TREATING & PURIFYING WATER USING COCONUT SHELL FIBRE

Coconut shell drinking water treatment

Siemens Water Technologies has developed a coconut shell-based carbon for drinking water treatment.

AquaCarb 1240CAT, which Siemens says is superior to the catalytic carbon used in water treatment, can provide improved results in water quality targets for chloramine, hydrogen sulphide (H2S), and hydrogen peroxide (H2O2) removal. The coconut shell base provides a higher adsorption capacity with extensive micropore structure for volatile organic compounds (VOCs), lower ash content and higher hardness/abrasion resistance, which can result in longer effective carbon life, reduced replacement frequency and lower overall life cycle costs as compared to traditional catalytic coal carbons in the market.

Suitable applications for AquaCarb 1240CAT 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,” claimed 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.”
AquaCarb 1240CAT catalytic carbon is part of Siemen’s Westates carbon product line for the North American market.
