Need help in design of purified water generation system

[Asisraja D]

Hi Professionals
I need your help in designing purified water generation system to our plant, we are manufacturing API product and we have set 4000 LPH RO system as a feed water for PW generation system but i don't have further how to develop the process and arrange things to initiate the design ? like after RO feed water what are the steps are involved in Purified water generation system. does anyone give your experience in this for me ?

Hi,
What do you mean by purified water? share with us the specification.

This is not a job for a mechanic.
Are you qualified about cGMP?

This is not a job for a mechanic.
i am a project engineer and involving in basic design so i was asked to order the system.

share with us the specification.
The specification i have is just plant capacity from my stakeholders.

What’s the water for? What is the reason for treatment? What’s the demand and required pressure? What’s the treatment capacity? What contaminants exist? Are there any health departments involved?

Hi,
If you don't know the specification of the water, how can you design/order a system?
The link supplied is a good one where you can get a good idea about process and equipment required.
You need to get those data and then contract a company (3rd party) for the job. It must be a company familiar with cGMP to validate the entire process after completion.
Troubles at the corner.
Good luck anyway.

we have to apply for FDA regulatory after commissioning and it is a greenfield project.

Well it's like any bit of process plant.

To make or design it, peop4need to know what's coming in with what contaminants or minerals or whatever and what's going out in terms of specification for minerals, contaminants, biological forms.

If you don't know that then you won't get anyone interested in giving you a design or a price. Talk to a few vendors and ask them what they need to know or get a few blank data sheets and try and fill them in.

RO plants from memory need about 2 to 3 times the flow in compared to flow out so that the concentrated water flows away somewhere. You will need to dispose of this excess impure water.

Oh and it's always best to use full words as API, PW etc can mean different things to different people in different countries. Always best to spell it out the first time.

In one of your posts, you wrote" we have to apply for FDA regulatory after commissioning".
This also make me feeling bad, your design must be in accordance with cGMP for the entire plant otherwise you have no chance to get approval from FDA or other authority, in particular US FDA or European EMA. This should be under the responsibility of your QA manager and Plant manager. Any person involved in this type of project must have a cGMP qualification, from Process to maintenance, lab, utilities, etc.
My personal experience, 1 warning letter from US FDA, it took months to resume production and to sell to US again.

Regarding water, pay attention to stagnant water, this is key for your design of your water supply. It should be a loop in operation 24/7, from network to users, pipe must be very short to prevent the growth of bacteria.
Compressed air is also a concern, compressor must be oil free. Same for Nitrogen, especially if you intend to use PSA to produce N2 from Air.

Sanitization is key for API production.

Note: An important document to submit to authorities is the Drug master file for your product. Hope you know what it is about.

Cheers,
I'm out.
