Which Filters are capable of pesticide removal and to what degree?

Question

I'm having trouble looking online for filters that will remove pesticides. I've looked at carbon filtering, UV lighting, and an indian nanotechnological filter.

If anyone knows of any sources that relate to my question help would be greatly appreciated.

Answer 1

What are the pesticides being removed from?

Because they are organic chemicals, pesticides can be filtered using ordinary activated charcoal. This can be incorporated into cartridges and worn in a breathing mask or as canisters in a water filtration system. Static electric air filter boxes remove dust, but can not remove airborne vapors (reguardless of what the manufacturer says!). The same applies to systems which use UV radiation, which only kills bacteria.

The best solution in an industrial setting is to equip workers with breathing masks. It would be a waste of energy to try and filter all the air in an entire factory. This approach is also used by farmers when applying pesticides to a field. There is no good in-home solution to pesticide pollution other than calling local government and reporting a possible overapplication of chemicals near your property. Water is much easier to filter than air. In-home water purification systems are effective ways to remove organic contaminants from drinking water. These units can be scaled up for industrial applications.

Answer 2

You cant remove pesticides by these filters. In drinking water quantity of pesticides is in ppm levels which cant be filtered out. You can find the amount of it by gas chromatography. By water analysis one can know the ppm level has crossed tolerance level or not, but cant seperate.

In general, you need to know which pesticides you have and then design a removal system for those chemicals.  Do not assume activated carbon will remove them.   Activated carbon is not 100% effective. More effective would be  actived carbon filters, followed by reverse osmosis.   TOC reducing UV lighting may also be helpful but again that depends on your situation.  If you tried UV lighting and that had no effect, chances are you were using a standard 254 nm UV bulb.  That is designed to kill bacteria.  TOC reducing UV, at 185 nm, would be more effective against pesticides because it is designed to oxidize hydrocarbons into CO2.  You may also need a pretreatment for the RO epending on your incoming water hardness.   HCl injection after RO may also be necessary depending on the application.  

So I hope you get my message here...Water contaminated with pesticides is serious.  Design of water treatment is complicated.   Best to hire a professional to analyze your water and treat it accordingly.

And as to nano filters, not sure which ones you're using here but Dow makes membranes under the brand filmtec.  They are expensive.  several hundred $ each.... And membranes can be a variety of pore sizes and efficiencies.   standard RO is about 10x more efficient than Dow NF90 (nano filters).

anyway, I'd recommend calling a professional.  Culligan has specialists in this field.  So does Siemens.   And others.   you could even try Dow.   here's a few links
