Is "PolyGlu” Flocculent Useful for Removing Mineral/Heavy Metals from Water?

Published on by in Technology

Does anyone have any experience in using Is "Polyglu” flocculent for removing mineral/heavy metals from water to make it potable?

Or is it only effective for large particles?

  2. Wow, thank you research team - I have learnt something new today that I will keep in my filing.

  3. The Water Network research t eam has consolidated an answer to the above question.  
    Further input from members is welcome and appreciated.  
     

    PolyGlu (polyglutamic acid) is a polymer of the amino acid glutamic acid (GA).

    Poly-γ-glutamic acid (γ-PGA) is a naturally-occurring polymer and it can be made from fermented soybean. It is, hence, completely environmentally-friendly.

    PolyGlu can be used to treat water and wastewater because of its flocculating activity. It is thought to work due to the electrostatic interaction between flocculants.
     

    Water purification with PolyGlu:

    When PolyGlu is added to water which needs treatment, stirring is required to help form the flocs. As the flocs form after a few minutes, you can stop stirring and wait a few minutes for the flocs to coagulate and settle to the bottom of the water. The water will be completely clear with the flocs settled on the bottom of the canister.

    These flocs need to be filtered out of the water. The advantage of this type of water purification is that any type of cloth can serve as a filter – even a T-shirt, which makes PolyGlu a good water treatment solution for third-world countries and for emergency water treatment.

    You should simply put the cloth over a and it will hold the flocs as the water passes through. The Water will then be clear.

    It is recommended that the water is disinfected by boiling or solar disinfection.
     

    1 g of PolyGlu can treat up to 5 l of raw water, depending on its turbidity and murkiness.
     

    Water purified with PolyGlu, by following the above instructions, is safe for human consumption.

    This process will remove parasites, bacteria, algae, viruses, fungi, minerals and heavy metals.

    Among its many uses, PloyGlu is used for Copper smelting, hence it is surely effective in removing metals from water.

    3. I love polu-glutamic acid, but I think we need to be careful to say it is a miracle solution. Even the video says it only treats the turbidity and still may require boiling. I am not convinced it will also remove all parasites, bacteria, viruses etc.
