Hazardous waste management and disposal
The most important question of galvanisation is the treatment
and disposal of hazardous waste.
We apply one of the most developed methods of concentrating sullage, based
on the principle of reverse osmosis.
The material rinsed off the workpieces becomes a useful component in the
galvanic bath. Valuable materials may be regained by the selective
treatment of the rinsing water.
We apply high pressure to lead the effluent rinsing water through a
semipermeable membrane.
Tiny water molecules get through the membrane and this filtered water can
be reused for rinsing.
Useful material that cannot pass the membrane become reusable after
reaching the appropriate concentration level.
After the first fill-up of the electroplating vat, this method ensures
minimum use of water, and the agent consumption will drop to considerably
compared to the traditional cleaning plant using chemical neutralisation.
Naturally, this system also produces waste.
Mixed rinsing waters, escaped water, wash-water, etc. that cannot be any
further in an cost-effective manner.
Still, the quantity thereof is only a fragment of the waste water residue
in a conventional sewage treatment plant.
This waste is collected and removed.

Occupational health aspects
In order to meet occupation health requirements, it is important to
maintain an adequate level of air quality. This is provided by a special
air exhaust and supply system.
The proper functioning of the systems is checked by regular inspection
of the condition of air at the workplace, and an emission check
of the load on ambient air at the ejector stack.
The ejector stack, as point source is authorised by the Environmental
Inspectorate.
