Dye Penetrant Testing and Fluorescent Particle Disposal

05/04/2009 9:36 AM

We do fluorescent Dye Penetrant Testing. All the waste water is collected by a waste company. To install a filter system that will take the fluorescent particles out of the water is ... very expensive.

We have tried "a homemade charcoal filter". It is better (slightly) but not yet what were looking for.

Can anybody help me?

Have you tried using Fenton's Reagent (a mixture of H2O2 & FeCl2)? It's very effective at oxidizing and destroying organic dyes. An alternative would be to use the electro-Fenton process i.e. a combination of electrocoagulation with iron terminals and H2O2. it is also highly effective at destroying organic dyes. The sludge can then be coagulated and flocculated out normally.

Hydrogen peroxide and ferrous chloride.

To try out viable decolourization technics need some more inputs to decide.

1]What is the quantity of water?

2]pH of output water.

3]Temperature of bath.

4]Amount of colour[dark or medium or faint]

5]Chemical class of flouescent dye[anoinic or basic[cationic]or pigment grade?

6]Anionic organic dyes can be separated by ferrous/alum coagulants in conjunction with poly electrolytes or by electro coagulation, whereas basic dyes need a different approach.Most of the flourescent dyes are BASIC dyes.

7]Is there any other chemical components involved in the test ?

Based on your inputs we can discuss further.

Get the details for 5&6.

The charcoal idea is not bad,in such case do you get carbon contaminations in water?

The quantity you are suggesting in just minor-you need not panic about.

The other simple option is to collect the water to a open large tray[fabricatable]possible black bottom coated and simply solar evaporate it.It could be a low cost remedy.

keep in touch.
