Water and Sewage Treatment: Expertise Unlimited

This is the polymer dosing pump and storage tank, for dosing an aluminium based coagulant for colour removal.

We refitted the old polymer dosing pump to a reconditioned IBC, and new downpipe. We also replaced its outgoing line with new twinwall stock.

The polymer pump was rewired to the new control system and interlocked to feed pump operation from its inverter.

This is the pH correction system, dosing up to 32% HCl and 20% NaOH by means of dosing pumps controlled by the yellow unit in the foreground.

Chemical storage is 2 No. 1000 L reconditioned IBCs.

Dosing lines are twin-wall for safety.

Chemical dosing operation is interlocked to feed pump operation via a feed from the inverter.

My French student is leaving today, so the supply of free assistance to my regular clients has ended!

The digestion experiments on PCB containing oily sludge seemed to give gently promising results, at least at 35C, so we may investigate further.

No problems with the turning down of the duff ETP's flow rate, so the client now has a bid for doing what is required to control the remaining non-compliances.

An enquiry for a metals removal plant came in this week, looks interesting, but the enquirer wants a free visit to discuss the job up-front, which may be problematic. I always find one can tell a serious from a speculative enquiry by whether the client will pay to meet you.

I've decided to start a blog on the company website, covering things which interest me professionally.

I'm a Chemical Engineer and Environmental Scientist, working mainly in the field of Water Engineering, though I do also deal in more general environmental advice, mostly on behalf of a government funded scheme called Envirowise.

I used to work for water contractors who you will not now have heard of, because it is seemingly a rule in the water industry that companies have to change the name of their company from time to time, for a number of reasons. For good companies, this is usually something to do with the marketing department. For bad companies, the reasons may be less honourable. None of the people I used to work for went bust by bidding jobs at less than cost and then came back one month later as "(old company name) 2008 Limited", but this is far from uncommon in the industry.

I do quite a bit of work of packaged sewage treatment plants which are misbehaving, look after some groundwater treatment plants, and am also presently involved in something I do a bit of from time to time, water feature design. I am helping with the design of water features in the Parc1 development in Korea. Don't click on the link unless you have broadband, the graphic designers have gone nuts on the website.

I'm also interested in water quackery, and will post some stuff on this as I come across new examples.
