Cabot Norit Activated Carbon Introduces Interactive Carbon Selection Tool for Sediment Remediation Applications

April 25, 2018

Quickly evaluate the performance and efficacy of Cabot NORIT┬«
SedimentPureÔäó powdered and granular activated carbons

BOSTON–(BUSINESS WIRE)–Cabot
Corporation (NYSE: CBT) today announced the availability of the
SedimentPureÔäó Activated Carbon Calculator, an interactive online
modeling tool designed to assist engineers, regulators and stakeholders
in evaluating in situ sediment remediation options using
activated carbon-based reactive caps and permeable reactive barriers.
Activated carbon has been identified as an effective material for
contaminant sequestration of chlorinated contaminants, such as
polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons
(PAHs) from sediment pore water.

This modeling tool, developed by CabotÔÇÖs research and development team,
leverages the CAPSIM
Model developed by Dr.
Danny Reible, Texas Tech University, for evaluating cap and in-situ
treatment performance in sediment remediation projects. It is a robust,
easy-to-use tool that can provide early guidance to engineers on
potential remediation solutions for a contaminated site using Cabot
NORIT SedimentPure activated carbons. The Cabot research and
development team ran over 500 CAPSIM Model simulations using a range of
real life scenarios to show the efficacy of activated carbon reactive
cap layers in remedial designs. The calculator output has a coefficient
of determination (R2) value of 94%, indicating that it is
highly predictive of the CAPSIM Model for the selected activated carbon
and parameter range of key variables such as activated carbon percent
(by weight applied in the cap layer), upwelling rate (cm/day), cap
thickness (cm) and design lifetime of the cap in years.

ÔÇ£Our SedimentPure Activated Carbon Calculator simplifies the complexity
of the CAPSIM Model under a set of actual field scenarios,ÔÇØ said David
Flannery, global marketing manager, Purification Solutions segment. ÔÇ£It
also provides instruction regarding factors that influence the
performance and efficacy of activated carbon in different forms under a
range of typical site conditions.ÔÇØ
