Water treatment solutions Ovivo

WATER TREATMENT SOLUTIONS

Unlike other resources, there is no substitute for water and only 0.3 per cent of Earth’s water is readily available freshwater. It is a resource that needs to be protected and valued. Marco Siebel spoke to the managing director, Harmen van der Kolk, to learn more about how the European Ovivo companies work together.

With over 200 years of experience, Ovivo is a world leader in engineered water treatment solutions. Ovivo’s expertise spans all industries and solutions applicable to water, waste-water and ultra-pure water. Ovivo has locations in 21 countries employing over 1500 people. Its European operations generated in 2011 revenues of over €180 million.

Ovivo operates locally, exchanging expertise between each company when the need for it arises.

In Europe, Ovivo has offices in the UK, Ireland, Switzerland, Germany, Austria, France, Spain and the Netherlands. Ovivo Holland is taking care of many projects all over the world for global companies with headquarters in the Benelux. Ovivo Holland has specialised in developing, building, installing and taking

care of the 24h/7 service of water installations used for the pharmaceutical, microelectronics, dialysis and energy sectors.

Harmen van der Kolk “We have been operating since 1976, working for the microelectronics and healthcare business sectors. Nowadays we are part of the Electronics & Metals division. Ovivo UK, part of the Energy division, is leading the energy market, and we take great pride in our way of working as an exceptional global team, with each Ovivo branch having its own centre of excellence.”

Ultra-pure water for the micro-electronics industry

Ovivo’s technologies remove impurities from water at the limits of their detection. The ultra-pure water needed for semiconductor manufacture is the purest water feasible. It is produced by combining conventional, membrane, ion exchange, thermal and oxidising treatment processes. Together with Ovivo Switzerland, Ovivo Holland designs and builds ultra-pure water treatment plants according to the latest ITRS road map specifications.

The pre-treatment section of an ultra-pure water plant uses filtration, ion exchange and membrane processes to produce permeate of lowest TOC and salt content.

Mr van der Kolk continued, “Due to our long experience in this market, customers choose Ovivo because of the design, quality and reliability of our systems. Our PLC control is one of our features in these plants.”

Ovivo also builds degasifying units, for the removal of gases such as oxygen and CO2 as well as some volatile organics. Mixedbed ion exchangers in a merry-go-round arrangement, or chemical-free treatments of electro-deionisation purify the permeate to the highest theoretical resistivity level. The external mixed-bed regeneration avoids traces of contaminants in the ultra-pure water system.

The polishing section provides for the final adjustment of the quality parameters, as well as for the temperature and pressure control in the distribution loop. All remaining ionic impurities are removed by polishing mixed-bed ion exchangers. Finally, the last remaining particles are removed by ultra-filtration systems before the ultra-pure water is distributed to the cold or hot consumers.

The ultra-pure water is typically distributed to the process equipment on the fabrication floor through a looped piping system designed for a continuous flow to avoid bacteria growth. Unconsumed ultrapure water is continuously recirculated to the ultra pure water tank for repurification in the polishing plant. Ovivo provides design, installation, supervision and certification of distribution systems, including hook-up installations to the process tools.

Demineralised water applications for the healthcare industry

The hardness of tap water generally ranges from 8° to 20° dH, often causing hardness sediment (scale). For this reason tap water must be softened with a water softener. For some applications partially softened water of 2° to 4° dH is needed, while other applications require total softening (softened water of < 0.1° dH).

To reach the level of demineralised water reversed osmosis or ion exchange is necessary. There are numerous applications for which demineralised water is needed. For dialysis patients, for example, special water treatment installations are required. This is

essential for conductivity, bacterial count and endotoxins. Next to this the whole dialysis flow system can be disinfected with ozone or hot water.

Demineralised water can be made in various ways. The most common methods are: softening/demineralisation followed by one or two passes of RO (reverse osmosis), demineralisation cartridge or an EDI (electro deionisation). In some circumstances it is also necessary to decrease the bacterial count, apart from the control and extermination of legionella.

Mr van der Kolk added, “Our integrated solutions range from equipment design, supply and installation to the integration of complete systems. With clean water becoming a rarer commodity by the day, our clients can be found all over the world – from Tunisia down through Ruanda and Madagascar to South Africa, and from India through China and Taiwan to Australia. Ovivo is there to increase our customers’ waterrelated safety and productivity.” The local presence of Ovivo is key to our way of doing business.
