Metal Treatment & Automotive
Without water, the industrial processing of metal products would be impossible. Water heats, it cools, it lubricates and conditions; it is a solvent that carries materials between processes and it washes away impurities. Many hundreds of cubic meters of water are required for the production of each tonne of finished metal. In industries that finish metal components, such as plating, electro and electronic industries, treatment is essential in order to remove substances from wastewater before it is discharged to reach release limits.
Spiraling prices of metal ors make effective extraction of all possible value from wastewater an essential cost-efficiency. Effective water management is attainable and making it an economic imperative.
Further details
Ovivo’s modular technology is able to manage water use at every stage of metal processing, ensuring that water is supplied and reused effectively and efficiently, and that wastewater is appropriately treated. Where wastewater is returned to the environment, our commitment is to enable you to treat official regulations as minimum requirements. But our aim is for you to extract the maximum value from the water resources at your disposal so that the maximum output is obtained from your processes at every stage.
The integration of Ovivo’s systems into the production process means that wastewater is treated wherever it is generated, and the minimal footprint of Ovivo technologies maximizes the return from land-use.
Our experienced teams of engineers, technicians and fitters plan, construct, assemble, install and commission plants. Whether designing a new or improving an existing operation, they can be relied upon to recommend the ideal processes, technologies and products for our clients to address their particular circumstances and to meet their specific requirements.

Treatment of Fresh Water for Make Up and Production
When supplying feed water to processes in which dissolved substances could interfere with normal operation, it is necessary to remove these unwanted substances.
This can be done by:
- Softening
- Deionization
- Membrane Technology
Rinse Water Recycling
Recirculation systems for rinsing water or processes require high quality, especially in surface treatment lines; two-stage or more rinsing steps are generally used.
- Deionization
- Membrane Technology
Wastewater Treatment
Ovivo is committed to meeting environmental standards, however exacting, wherever our technology is integrated into industrial operations. In some cases, selective ion exchangers are used as end-of-pipe systems to ensure compliance with any local limits for the output of heavy metals.
The processes employed include:
- Detoxification
- Chemical Physical Treatment
- Sedimentation
- Sludge Dewatering
- Final Treatment
Biological Methods
Biological methods can be used alone or as part of a multi-stage system for the treatment of wastewater as long as the substances in the water are suitable for biological decomposition. If this is the case, biological methods have clear advantages over other methods for wastewater cleaning as dirt, contamination, wastewater quantities and the heterogeneity in the quality of wastewater increases. Also for water reuse in dairy production; COD, BOD and Nitrogen removal
Sludge handling
The sludge produced from metal removal plants often contains precipitated metal hydroxide solids, which are ideally suited to dewatering in Ovivo’s plate and frame filter press. Mechanical sludge dewatering is often an economical means of reducing sludge volumes produced by wastewater treatment plants. Ovivo filter press solutions have plates with durable, permeable cloth and are supplied ready to install. They meet the client’s need so effectively that dewatering will result in a sludge cake with up to 40% solids.
Specialist Recovery Technology
Recycling of process solutions integrated in the production lines with Ovivo’s technologies are available. Reduction of wastewater and recycling of valuable substances is done at the same time. Most of these processes need to be combined with purification methods to carry away impurities before recycling. This is, for example, done by special ion exchangers.
These processes include:
- Acid Recovery /Regeneration
- Vacuum Evaporator Systems
- Copper Recovery
- Nickel recovery
- Precious Metal Recovery
- Electrochemical Methods
- Energy Recovery from Wastewater
- Membrane Technology
