Powdered Activated Carbon (PAC) Adsorbtion

Powdered Activated Carbon (PAC) Adsorbtion

Powdered Activated Carbon (PAC) Adsorbtion


I am considering utilizing a powdered activated carbon (PAC) process to reduce organic species concentrations in a product stream.  Basically, I believe this could be done batchwise - with sufficient agitation.  

However, I have run into some difficulty finding filtration technologies to remove the slurried PAC after the requisite contact time.  I was thinking some type of DE filter, possibly, or something else utilizing a pre-coat step.  PAC mean particle size is about 100,000 Angstroms.

Any suggestions?

Thanks All.  


RE: Powdered Activated Carbon (PAC) Adsorbtion

We do this some times to clean up a product stream.  We will put the powered carbon in with a product called celite.  You need about as much celite as you do carbon to get it to filter.  It will work on about any type of filter that is big enough to hold the cake.

It is fairly well established use of activated carbon (since the seventies) although for ease of handling it is granulated.

White Paper - How ESI is Helping Move New Medical Device Product to Market Quicker & More Cost Effic
Early Supplier Involvement has long been a strategy employed by manufacturers to produce innovative products. Now, it almost seems like a necessity. Because decisions made in the design phase can positively affect product quality and costs, this can help add value to OEM bottom lines. This white paper will discuss many facets of ESI, including why it’s so valuable today, what challenges limit the benefits of ESI, how cost is impacted, and more. Download Now
White Paper - Moving to a Driverless Future
This white paper describes what we see as the best practices to support a sustainable engineering process for autonomous vehicle design. It exposes how to use simulation and testing in common frameworks to enable design exploration, verification and validation for the development of autonomous cars at a system, software and full-vehicle level to drive a mature product development process for automated driving.
