No emissions, no waste, no problems with clean water recovered from industrial waste products. In this one sentence you can describe the technology of ROVAPO™, which enables the production of very clean technological water. ROVAPO™ is a closed water circulation technology that minimizes energy consumption and resulting waste products. It is a tech – nology as clean as the water it generates. ROVAPO™ also means a high level of water recycled for repeat use (up to 95%).
ROVAPO™ is an original solution supported by a range of patents. It is part of the technology family named “zero liquid discharge” and enables full recovery of water from sewage. Depending on the industry, the ROVAPO™ system enables the recovery of demineralised water of <10ms, e.g. for galvanizing production, superclean deionised water, e.g. in photovoltaics or pharmaceuticals, or water with parameters allowing its repeat use in production processes. ROVAPO™ technology encompasses a range of treatment levels, allowing the achievement of the established goal: selection of streams and chemical treatment, membrane systems and evaporation systems. ROVAPO™ technology has been designed for waste products from galvanizing processes and hightech industries. The basic configuration can be interchangeably supplemented with components for use on other waste products – initially treated chemically and biologically with an active sediment and ultra-filtration membrane (MBR AeroMem™ Reactors). In the newly-developed ROVAPO-HF configuration, it is possible to fully clean wastes from the extraction of shale gas.
Avantages of the solution:
- It enables the recovery of water from waste prod – ucts with an efficiency level above 98% (including recovery of high-quality water from waste subjected to biological filtering)
- It is based on original programming that steers the automated functioning of the installation, independently of varying quantities and compositions of waste from production, as well as ensuring a constant output level from the unit
- It reduces to a minimal level the amount of waste output – the one waste product is a concentrated deposit from the chemical element and concen – trated salt from an evaporator containing approx. 50% dry mass
The first investment using ROVAPO™ technology was designed and installed “ready to go” in 2006 at the aviation facilities of Augusta Westland PZL – Świdnik. It was Poland’s first modern waste treatment plant with a fully closed water circulation from the new galvanizing plant. Instead of galvanization waste products in a classic treatment process being led to the municipal sewer system, high-quality demineralised water is produced from sewage with strictly defined and guaranteed parameters. It is returned to production processes in a modern galvanization plant servicing the production of aviation parts. In 2010-2019 a new ROVAPO™ installations were activated, in particular in aviation and automotive industries.
