Our Solutions
At Ovivo we are partners of our clients in order to develop totally customized process and water treatment solutions to meet their needs.
Our Motivation for the Development of Sustainable Technologies is a Law named:
- Closed Substance Cycle Waste Management and Environmentally Compatible Waste Disposal
The political credo of modern waste policy is:
- Avoidance, recycling, environmentally sound disposal!
The purpose is to promote closed substance cycle waste management in order to conserve natural resources and to ensure environmentally compatible disposal of waste.
This means to apply:
- the avoidance,
- recovery and
- disposal of waste
with advanced technologies.
Waste has to be reused as far as it is technical feasible and economically reasonable.
Such technologies are called State of the Art. State of the Art means the use of low-waste technology as well as recycling or reuse of waste and the recirculation of waste. A very important point is to separate different types of waste.
Ovivo’s modular technology is able to manage water use at every stage of 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.

With Ovivo’s water management expertise, we are able to offer a complete range of state of the art systems, components and processes for industrial operations.
Treatment of Fresh Water for electronics 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.
The processes employed includes:
Separation of waste water in several streams:
Free of complexing agents
with complexing agents
high and low COD
This allows a save and environmentally friendly treatment with different possible steps
- Detoxification
- Chemical Physical Treatment
- Sedimentation
- Sludge Dewatering
- Final Treatment
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
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.
- COD, BOD, 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 includes:
- Copper recovery
- Reoxidation of spend oxidants like sodium peroxodisulfate
- Reuse of hydrochloric acid for copper
- Vacuum Evaporator Systems for Zero liquid discharge
- Precious Metal Recovery
- Electrochemical Methods
- Membrane Technology
