I have prepared the material for the removal of heavy metals from the wastewater. Now, I want to test it over the filter. How can I coat the material on the filter? Either should I dip the filter into the prepared material or pour it on the filter paper?
Ok, depends on what material you have. Normally I'd tell you to filter the removal material through the filter prior to running a sample but I have no clue what you are using. Is it a solid? Can you disperse it in water or another readily-filtrable liquid? Will the filter trap it? You have to be able to answer all of these questions before you can decide how to get it on the filter.
Noor Ul Ain Consider how your material is supposed to work as a water treatment technology and how it is formulated now.
E.g. perhaps you made an ion exchanger type of sorbent. It will need some reaction time to sorbe metals so typically the final application is a column of the material with some minutes retention time. If your material are granular you can build a small column and simulate the retention time by controlling the flow.
If your material is a powder you can just make batch test with metals in water and separate the powder by filtering. Then you have some modeling to do to estimate how it would work in a filter.
Henrik Rasmus Andersen it is nanocomposite polymer material. I have performed the batch tests and now I want to check the removal of heavy metals by coating the material over the RO membranes. So my query is whether I should layer the liquid material over the leaf of filter and what should be the thickness of coat?
I think it depends on what kind of material you have. Normally I'd tell you to filter the removal material through the filter prior to running a sample but I have a clue what you are using. it a solid
Noor Al Ain.... First you need not to stick to your filter. We've tried mixing clay materials like montmorillonite or Kaolinite for a given time to work as adsorbents for metals like Pb, Cr, or Ni successfully
