How do we clean the active bone dust in the mesh

Try washing it with alcohol first before applying the steam. Alcohol will dissolve away the oil that enables the dust to stick to the carbon. It also has very poor adhesion to activated carbon. Finally, have you considered placing a fabric filter layer before the carbon filter layer? This will help to trap the dust before it reaches the carbon layer.

My freind;

Thank you so much for your timing response, but can we try to cleaning the mesh automatically? the alcohol is perfect agent for the active carbon cleaning, but if it apply in automatically cleaning that it seem like unfeasible, as I know the alcohol is dangerous while it's working under high temperature condition. in manualy the alcohol is good ways in cleaning.

we have placing a fabric layer before the carbon filter layer, thanks for your value comments.

Sincerely regards

Pory

You can try using a hot soap water of detergent solution instead of alcohol. I don't know what type may be suitable as different types of activated carbon may or may not adsorb them. If you can find a suitable detergent, spray it on, then rinse it off with hot water before applying hot dry air to dry it. Finally, apply steam to remove loosened particles.

Thank you for your value suggestion, I think some solve agent is suitbale for the strong residue cleaning, but it's property shold be mildness since it apply for the hot temperature working condition, I have to ask chemical expert for sugesstion as well. After I got the information, if you like I can share with you for chemcial expert opinions.

I agree with Sisira on this issue. I am an engineer working in the field of odour control. We use activated carbon as a "polishing" agent generally after biological treatment, because of its ability to adsorb mercaptans, VOC's and DMS. When the carbon is "saturated", ie can no longer adsorb any more odour we replace it with fresh AC and the saturated product is sent to landfill or incinerated. I agree also with Sisira that there is nothing to be gained in steam cleaning the AC as you immediately return the captured VOC's etc back to the environment.

What I have seen in use of Activated Carbon is that there is a pre-filter before the activated Carbon to trap the larger particles.

In Liquids a Sand Filter often is installed before the AC filter

With Air I envision A series of Air filters (Cartyridge type) that you can replace. The cloth concept is very interestiong and I wonder if you could use a Vortex type system that precipitates solid particles for collection ...then use a series of progressively

Finer Air (cartridge filters- Like the ones used for Air Conditioning unites, or similar)

The you would send the Cleaned Air without particles to the Activated Carbon

Tank. I thin this would make the AC last longer before replacing.

You can set up a similar Vortex system at the exit of the Activated Carbon Tank to collect AC dust before the Mesh that you want to clean ...

If gas stream contains dust particles, a prefilter is used for particle filtration and it in most instances can be taken out and cleaned by washing/compressed air. After filtering out the particles present in gas stream it is sent through the AC bed to remove VOCs etc.

AC is not used to filter out particles, large or small.

If AC dust is created in the process then either you are creating too much turbulence in the AC bed or using a structurally weak carbon.

Hi,Mr.Pete:

I am much appreicate for your valume comments, we are specialise in painting equipment field, actually our business focus on painting and surface treatment device research, although waste air treatment is our subordinate business, but nowdays more and more request us to provide relevant equipment with painting equipment, as I know you are professional bilogical odour treatment device supplier, could you advice me your detail proposal for the biotrickling fiter? we are very appreicate if you can share your oponions and brief sketch drawing for filter tank description.

Detail about our business, welcome you visit my company website for detial,www.fungyu.com.hk

Have you investigated photocatalytic process to eliminate the organic compounds? This will not help with the particualte content, but it will break down the compounds and render them harmless in many cases.
