Whilst being unfamiliar with both the varnish and thinner you are using, this seems to be a Volatile Organic Carbon control problem.
There are quite a few options. A good book to get you started is this one http://www.amazon.com/Odor-Control-Handbook-Harold-Rafson/dp/0070525234
This is why I clarified what I was talking about in my previous post, as confusion seems to have arisen. I was replying to the person who suggested "shocking the well by injecting chlorine into the aquifer", rather than you, Bimr.
This is why I said "the NI Environment Agency will get very...
PVC has been targeted by environmental campaign groups like Greenpeace, using propaganda techniques- put "poison plastic" into Google to see what I mean. The overwhelming majority of these claims are either groundless or outdated, based on risks which no longer exist.
Despite this, the...
Just to be clear, I am saying that putting chlorinated water into any aquifer, whether that be groundwater or surface will be frowned upon.
I have been engaged for eight years to give advice on these matters by the UK government, but things do change, so I have spoken to the NIEA this morning...
Hi Pearse,
I think you will find that the NI Environment Agency will get very upset if you start putting chlorine into their aquifers. It might be different overseas, but in the UK this is highly unlikely to be allowed. Putting anything into the water environment is very tightly regulated...
I'm not sure I'm understanding the question, but Cv is used to calculate flow. It gives the relationship between flow and pressure drop. Flow is proportional to absolute inlet pressure. Hence if you know inlet pressure and valve rotation angle, the Cv figures you have can be used to calculate...
Thin-walled low-grade stainless often saves on installation and maintenance costs so as to be cost competitive for above-water pipework. It's quite extensively used in the UK, teamed with uPVC for the permanently submerged sections.

Nozzles like this are made by a company called Cadar http://www.cadar.ltd.uk/ here in the UK.
They will have been bought in by the vessel manufacturer from such an OEM supplier. They will sell you spares, but there will be a markup of course.

Hi Ferex,
there are a number of factors:
1. Selection of materials suitable for the chemical composition, pressure and temperature of the contents. Perry's has useful tables for materials selection by these criteria, as do various pipe manufacturers.
2. Industry standards. For essentially...
I have a manual on water feature design on my website here:

What has not been remarked on by other posters is that the Chemineer HEV has superior performance against blockages, as the mixing elements are secured to the walls of the pipe, leaving a clear void down the centre.

You'd be unwise to try to design you own from scratch, in all likelihood. Probably better to go to one of the proprietary manufacturers, though BAF's a bit old hat now, and you can get a similar process footprint from deep activated sludge tanks.
There are a number of potential design problems...
