Water Treatment: Food Drink Beverage and Dairy Industry Regulation

I've worked in many different industries during nearly thirty years of practicing as an engineer. I'm presently having a lot to do with dairy technology, an area I have worked in a few times before as a trainer and process troubleshooter.

Milk products are however not the drink I have had most to do with, and I have been thinking this week about why the idea of what is "hygienic" is so radically different between drinking water plants producing a municipal supply and those producing a bottled supply.

It appears that this is to do with US regulation. In considering the level of contaminants allowed in municipal drinking water, a rational science based approach is followed. We design plants to reliably keep contaminants below a specified level. If however we want to sell water as a beverage into the US, we need to have a product produced under "sanitary" conditions to cGMP, as eth FDA regulates bottled water ( but not municipal water supply).    


Engineering Water and Other Utilities in a Hygienic Environment

I'm as busy as I have ever been, with multiple potential projects in water, pharma, nutraceuticals and traditional chemical engineering.

I've got  a couple of new contracts about to start on top of the bread and butter nutraceuticals job I spend most of my week on. I've got another HAZOP there next week, and another one in the offing.

Its good to be busy. I'm glad I insisted on having two years to write my new book! My last book is making its way into print, will be out in July, apparently. I can write books faster than they can publish them!

HAZOP and Water Issues in Hygienic Industries

I chaired a HAZOP this week, which I was trained in a long time ago, and still do on occasion, focussing on hygienic issues in a nutraceutical plant.  As ever, we all learned something, even the guys who had been operating the plant for thirty years. HAZOP is a powerful tool.

I've also been looking at a few water issues, and I was once again reminded of so many past experiences of people assuming water is simple. I have seen examples of under and overspecification this week. How to avoid this? Ask a water specialist. It is a false economy not to.

Water issues in the hygienic industries

I'm having a lot to do with water issues in hygienic industries at the moment. The EHEDG have a new guidance document out on this that I haven't read yet, but all of the guidance says the same thing, really. I'm pretty sure I can guess what it will say.

Avoid deadlegs, use hygienic materials and methods of construction, etc..

The application of this guidance in practice is where the skill lies....
