Reclaim Systems

For reasons of water management efficiency or environmental regulation, wastewater is expelled from processes much less frequently. So unwanted substances remain in metal processes and their removal is necessary to optimize continuing operational efficiency. 

Ovivo’s ion exchange technology carries impurities away either via drag-out or with the aid of feed/bleed operations.

Ovivo has developed special vacuum evaporator systems. These offer a mild concentration method for sensitive media. For instance, concentrating chromic acid enables the recovery of substances carried out of plating processes. This method can also concentrate alkaline electrolytes, or electrolytes containing cyanide.

In recent years, metal commodity prices have spiraled upwards and exerted enormous cost pressures on metal processing industries, particularly in the surface treatment and printed circuit board sectors, which use copper and nickel. 

Ovivo offers process-integrated recycling systems to help operations extract the maximum value from the water that they use. 

Ovivo’s innovative process for recovering metallic copper from copper-containing rinse water begins with pre-treatment. All copper containing component currents are concentrated by using a special ion exchanger with high capacity. The operating conditions are adjusted to separate unwanted substances such as ferric and zinc ions at once. A copper-free discharge results. 

A final neutralization removes chlorides and organic components so that metallic copper can be removed from the wastewater by means of an electrolytic cell plate. 

Nickel ions from chloric and sulfatic rinse water are concentrated using a special ion exchanger with high capacity. Water is discharged nickel-free. 

Final neutralization, removes chlorides and organic components so that metallic nickel can be recovered from the wastewater by means of an electrolytic cell plate. 

Recycling applications with ion exchangers include the removal of Fe/Cr-III from chrome-plating electrolytes and the removal of aluminum from anodizing baths by means of retardation systems.

Electrolysis cells are used for the recovery of valuable substances from solutions containing metal ions, such as gold, silver, copper and nickel. The anodic oxidation of substances such as cyanides and complexing agents in wastewater simplifies further treatment.

The anodic oxidation of substances such as cyanides and complexing agents in wastewater simplifies further treatment.

Considerable savings can be achieved by combining heat exchangers and heat pumps to recover heat from contaminated thermal wastewater. 

Ovivo has been successful in planning and delivering energy recovery systems as an integrated, effective byproduct of metal-processing operations.

Ovivo’s membrane technology is used widely in the recycling sector. Ultra and microfiltration systems separate emulsions and recover degreasing solutions containing surfactants. Ultrafiltration systems also pre-treat pickling solutions while reverse osmosis is used to recycle dye baths.

The increased commodity prices for metals have exerted an enormous cost pressure in the last few years. This situation affects particularly the surface treatment and printed circuit board (PCB) industry. 

The duplication of the price of electrolyte copper in the last 3 years boosts the cost for many companies. Especially for those, who process copper and produce PCB’s. 

To counter this effect we offer you a process-integrated copper recycling system. Many companies will be convinced to invest in a customised recycling plant after considering all points of profitability.

Ovivo has developed an innovative concept for the recovery of metallic copper from copper-containing rinse water. After pre-treatment, all copper-containing component currents will be resumed and concentrated by using a special ion exchanger with high capacity. The operating conditions are adjusted to separate unwanted substances as ferric and zinc ions at the same time. The discharge is almost free of copper and can be led in to the final neutralisation. The regenerated effluent is free of chlorides and organic components. Due to its high copper content it is possible to recover economic metallic copper by means of a plate electrolytic cell. 

We can also offer you an economic solution for nickel recycling, e.g. for surface treatment finishing companies.

The increased commodity prices for metals have exerted an enormous cost pressure in the last few years. This situation affects particularly the surface treatment industry.

The triplication of the price of electrolyte nickel in the last 4 years boosts the cost for the surface treatment finishing companies. Especially for those, who process nickel and work in the field of decorative chromium plating.

To counter this effect we offer you a process-integrated nickel recycling system. Many companies will be convinced to invest in a customised recycling plant after considering all points of profitability – where Ovivo creates value.

Ovivo has developed an innovative concept for the recovery of metallic nickel from nickel-containing rinse water. This process concentrates nickel ions from chloric and sulphate rinse water using a special ion exchanger with high capacity. The discharge is nickel free and can be led into the final neutralisation. The regeneration effluent is free of chlorides and organic components. Due to its high nickel content it is possible to recover metallic nickel by means of a plate electrolytic cell with high electricity yield.
