Surface treatment processes are widely used in the production of metal parts; they can be functional, as those aimed at protecting from corrosion or wear; aesthetical, like painting or coating; or both, as aluminum anodizing.
These processes are used for metal objects utilized in a large number of industries, amongst which:
- the automotive industry
- the aerospace industry
- the production of household appliances
- the furniture industry
- the industry related to solar and photovoltaic energy
- microelectronics and many others
Surface treatments’ wastewater: extremely dangerous and polluting
The surface treatment industry produces large quantities of water containing extremely dangerous and polluting elements as heavy metals, organic substances, cyanides and other suspended solids.
The most common wastewater streams generated from the surface treatment industry are:
- oil emulsions
- exhausted baths containing heavy metals (such as chromium, zinc, copper etc.)
- water based lubricants
- wastewater from rinsing and degreasing lines
- floor washing waters
- compressor blow down
Wastewater treatment for nickel plating, tin plating, chrome plating, copper plating, galvanizing
Different surface treatments may be applied depending on both the purpose of the treatment and the type of metal onto which it is applied. Our wastewater treatment technologies are thus prepared to treat a lot of different metals in water, making our wastewater treatment equipment the ideal solution for:
- chrome plating wastewater treatment
- nickel plating wastewater treatment
- chromium plating wastewater treatment
- galvanic wastewater treatment
- tin plating wastewater treatment
- copper plating wastewater treatment
- treatment of water from hedging with other metals, more or less precious.
The waste water deriving from these processes can be essentially categorized into:
- Water from cleaning or surface preparation processes: degreasing, pickling and rinsing baths in general, including the water used for rinsing floors.
- Water from covering and surface finishing processes: waters used for the composition of the various treatment and covering applications, as the exhausted baths, those used for the anodizing, galvanic processes etc.
