  1. You didn’t provide any information on the need/application so I suggest you approach this in a general way.   

    When looking for water treatment chemicals you will typically have the best chance of finding what you need from one of the companies specializing in them - Nalco, Betz, Calvin etc.; or whatever name these companies are currently known by (it’s been a lot of years since I worked with any of them).  I suggest questioning the local water treatment supply chemical companies in the country where they will be used as not all chemicals are available in all countries.  Additionally, most of the treatment chemical companies have proprietary blends of chemicals that they sell for various needs in each country they do business in.  The company name for these can change depending on where you are.  Further complicating this is the companies are often resistant to detail the composition of their products.  

    While going to a chemical supplier and having them do testing to identify the best solution to your need may duplicate work you’ve presumably performed, it is very possible that experts in this field may be able to offer you some products that are readily available. 

    I expect that you will end up having to establish a relationship with a local water treatment chemical supplier in the location they will be required.
     

    As you listed some very specific chemicals; I assume that you have done testing to determine this set of chemicals will meet the need.  They may or may not be readily available in the location they are needed. And they are likely not the only chemicals that will meet the need  You should also be open to allowing these water treatment experts to evaluate your specific needs and propose chemicals that are readily available - something being commercially sold that meets the treatment need is likely less expensive than some complex mix of chemicals that are hard to find.  There are often many different chemicals that meet specific treatment needs.  I suggest an open mind to other possibilities.  

    If you end up purchasing chemicals for this need from one of the major water treatment suppliers you might want to use their services to routinely monitor the performance of the chemicals you are purchasing and to provide guidance for any needed adjustments.  

    Make sure that you have them test their chemicals under all foreseeable conditions before finalizing a solution to your need. 
    i strongly suggest that you use one of the chemical suppliers in this field rather than try and identify a chemical mix and then handle everything yourself.   The fact that you are looking for help finding these chemicals indicates you very possibly need.help selecting the best mix of chemicals as well as help with making the necessary daily adjustments to your process.   

    Good luck.

      Thanks for your valuable comments which is and will be very helpful in future

  3. First question, what ratios? Second, our firm goes by ANSI certification, not NSF.

    1. Since the products will be used to treat potable water, the company is looking for NSF certification
