OMC Collareda Srl

The mission of O.M.C. Collareda is to research new technologies with the aim of achieving three key results: the recycling of raw materials, water recovery and energy saving. All this with an eye to the environment both when it comes to ensuring compliance with national laws and the standards of the countries where its customers are located: OMC examines the given situation case by case, offering its customers the best solutions and making its advanced technologies available to them.

This is precisely our strength: to meet with customers in person, presenting a comprehensive technical file with detailed drawings of the plants and offering them an industrial know-how that can count on our extensive experience in the field. What makes the difference is our ability to be a reliable partner for our customers and not just mere suppliers. Our production of water treatment plants includes dissolved air flotation systems DELTAFLOAT and TIGERFLOAT, dissolved air settling-flotation systems SEDIDELTAFLOAT, continuous self-cleaning sand filters OMEGAFILTER, drum filters GAMMAFILTER, fractioning/separator filters SIGMAFILTER, disc filters DENSIDISC and filters for water micro-filtration MICRO-FILTER.

O.M.C. Collareda is an international leading company in manufacturing equipment for Water Treatment Plants and Stock Preparation for Paper Industry

When it comes to drainage systems, instead, O.M.C. Collareda designs and manufactures Biological Plants according to different technologies, such as activated sludge oxidation AST, MBBR – Moving Bed Biofilm Reactor MBR – Membrane Biological Reactor, with the aim of recovering some of the treated water.

Another important line of business are primary and process waters from rivers, lakes and polluted groundwater: our Primary Water Division designs and manufactures systems for filtration, ultra-filtration and reverse osmosis. This division offers equipment and systems for filtration on sand beds, iron removal systems, activated carbon filtration, ion exchange plants, electro-deionisation, micro-filtration & nano-filtration, seawater desalination, UV sterilisation, ozonation and containerised systems.

O.M.C. Collareda Srl can also offer its range of plants and systems for stock preparation for paper mills. In recent years, we have made considerable efforts to meet the new needs of the paper industry. Flexibility and modularity coupled with knowledge of the process are now the key words in the design phase. Machines like pulpers, screens, cleaners, fractionators, flotation cells, washers, hot dispersion plants, under-machine pulpers, refiners, deflakers and stirrers are an integral part of our production. Individual machines or complete lines for stock preparation can be designed and manufactured to meet all customer requirements and for any type of paper or cardboard products.

Extensive experience and organisation enable O.M.C. Collareda not only to build equipment, but also to develop any engineering project in specific fields of industry, provide turnkey installations anywhere and carry out studies for the improvement of existing water cycles. All this is made possible thanks to a widespread sales network that allows us to reach and serve every corner of the world, a specialised Technical Department, where skilled technicians are steadily at work researching and developing new projects in order to be abreast of the times, and an R&D laboratory that has the most modern tools, which are essential nowadays to be competitive and to constantly upgrade the technologies we offer. First established to provide solutions for wastewater treatment in paper mills in particular, over the years O.M.C. Collareda has widely diversified its business, so that today it spans many civil and industrial sectors: from the petrochemical industry to the food and dairy industry; from meat and fish processing to the textile and tanning industry.

Our Company also purifies primary and secondary water for civil and industrial biological plants, water produced by the wine and beverage industry, brewery effluents and much more. You can be sure that wherever the manufacturing process involves water to be purified, O.M.C. Collareda will be there!

It’s hard to say in which countries in the world today at least one of our plants hasn’t been installed: besides all throughout Europe, O.M.C. Collareda is present in the Maghreb, the Middle East, in Central and South America, Oceania, Japan, Russia and China.


The fact that we can offer our own technology worldwide while yet boasting that all components are Made in Italy is today one of our greatest satisfactions. In fact, the design, manufacture and after-sales service are all based in our headquarters in Schio, which is where not only all ideas and experiments are hatched and conducted, but is also the site of production of high-quality products. In the near future, O.M.C. Collareda Srl expects to grow even further, looking for new markets and new technologies for cleaning up pollution in general, and our goals will be to increase the diversification of our products and further enhance the customer service and engineering consulting available to our customers. A major bet for O.M.C. Collareda: the desire to always put ourselves to the test, the ability to keep up with new advancements and an unwavering commitment to a future where technology helps humans to interact sustainably with the planet’s energy resources.
