Water and Hygienic Engineering: Busy

I'm working this weekend, which I normally try to avoid, but this time it's unavoidable. I have a new expert witness contract, as well as my main break and butter hygienic design contract, and I have a little hump to get over

When you are a small company, you need to do this once in a while, though I'm not a subscriber to the idea that freedom for a small business owner is being able to work any seven days of the week you like...

Expert Witness Sewage And Sludge Treatment Process Chemical Environmental Engineer

We received  a new inquiry yesterday for a sewage sludge treatment job overseas. Ive done quite a lot of design and troubleshooting in the area, and most of my expert witness work has been of this type.

Expert witness jobs are always interesting. Figuring out what has gone wrong, and how much of that was down to design, and how much to installation, operation or maintenance is an intellectual and professional challenge I relish. I don't mind a bit of travel either.

Chemical Engineering Dictionary

I was supposedly on holiday this week, but I've been working on my next book, a dictionary of chemical engineering practice.

It's a lot more interesting than it sounds, as I get to have a lot of conversations with my fellow chemical engineers about what they think the words we uses in professional practice mean.

Of course, such conversations may not be everyone's idea of fun, or a holiday. That they are mine might be the reason why I'm writing a dictionary!


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....
