Special techniques : advanced wastewater reuse – combined RO (reverse osmosis) and MBR (membrane bio reactors) installation – cost saving measures
Water is getting more and more expensive anywhere in the world. Companies are paying more and more for waste water disposal. This is leading to an increasing demand for reuse of waste water, certainly for the big water consumers, such as slaughter houses, laundries, food and beverage industry, cosmetic industry, textile industry, etc.).
Inserting a RO installation in addition to a MBR unit, is allowing to reuse a substantial part of the wastewater (approx. 60 to 80 %) in the production process. For the companies concerned the savings on water supply and wastewater disposal are considerable, allowing to recover the investment relatively soon. Knowing that water cost will continue to increase for companies all over the world, measures taken to reduce this water cost to the maximum are absolutely crucial. The exploitation cost for such a combined RO – MBR installation, according to the customer’s specific needs, can e.g. only represent a third of the cost of city water.
For each specific project there is a previous feasibility check, by means of performance and dimensioning test on site. Whenever appropriate a test installation is installed for a lost check-up. The final full scale installation is entirely custom-made, in function of the wastewater type, the aimed quality for reuse and taking into account the economic aspects of the project. The MBR unit in container, as well as the RO unit mounted on skid, come as compact entities, easy to integrate in an existing water treatment environment. The RO installation is fully automated and completely remote controlled.
We dispose of 30 years of knowhow in the field of membrane technology and can present four specific references so far (at the end of 2015 to first installation has been put into service successfully, 3 more installations are to follow at the beginning of 2016).
