Sodium sulphide is one of the oldest known metal precipitants used in industrial waste water treatment in electroplating. Traditionally, sodium sulphide is often used for galvanizing, but also for copper plating in the printed circuit board sector. Whenever pure hydroxide precipitation is not sufficient, sulphides that produce metal salts with very low residual solubility are used. (...)

Replacing problematic solvents - tailored to your needs - with sustainable specialty cleaners

In recent years, chemical regulations in various parts of the world (REACH in Europe, TSCA in the USA) have resulted in an increasing number of solvents and cleaning products being re-evaluated and reclassified for their toxicological effects. Well-known and highly effective substances such as NMP (N-methylpyrrolidone), NEP (N-ethylpyrrolidone) and DMF (dimethylformamide) have been subjected to stricter classifications with new labelling requirements and their use has been restricted in some cases.

Färber & Schmid is number 1!

The Indutrade Process, Energy & Water Leadership Conference took place from 27 to 29 January in Munich. (...)

A large company specializing in the production of printed circuit boards was confronted with problems in the treatment of waste water containing resins. This wastewater from the production process, when stripping the resist film from the printed circuit board, produced sludge that was extremely difficult to dewater, causing the downstream chamber filter press to become clogged within a very short time and requiring extensive cleaning every two days. In addition, there were always wastewater batches with residual turbidity, which meant that the treatment had to be repeated and took a lot of time. (...)

DE-Paint XN-77 - Speciality cleaner

Users of alkaline-based washing systems often encounter the same problems again and again:

•  Foam formation
•  Odour pollution
•  Poor cleaning performance

Machine downtime, increased costs due to additional labour and bath maintenance, the use of appropriate PPE, more washing cycles and a lot of manual rework are the difficulties associated with this. (...)
