Dear Mr/Mrs TN,

Our environment government has declared that we must leave the use of VIGON A200 and use other and less contaminative cleaner. We have installed carbon filters and other stuff, but the sword  hangs over our heads still. Reason is said to be this: when our process water is added to the commune's waste water system, our waste water contains too much of COD(Cr) which is 'oxygen consuming compounds'. Furthermore, the requirements say, that the 'nitrification retardment factor'  must be maximum 20% when our contribution is 20%, and maximum 40% when our contribution is 50%.  There is no way out, they say, we must change to another cleaning process.

Now, all know that a 30 feet long automatic cleaner is quite a lot of money, and to verify a new process means a lot of money too.

Anyone out there with experience from escaping hungry wolves? I'm not against environment protection and all that greenish, but in this case it seems like bureaucracy fulfilness rather than sense.

Q1: after flux removal and water cleaning and drying, what 'oxygen consuming compounds' can develop? 
Q2: what is 'nitrification retardment factor'?
Q3: what more can be done than installing extra carbon filters?

PS. Had a long message from our Cyprus man long ago, but he never said anything about these Vigon disadvantageous properties.
