Pile Cloth Media Filtration

Hydrok have the UK distribution for the Mecana Pile Cloth Filter Media within their portfolio of Wastewater Treatment Processes.

Swiss Company Mecana has over 45 years experience in the development of tertiary filtration systems, with hundreds of reference sites across Europe and in the United States.
The Mecana range of Pile Cloth Media Filters are available to treat flows ranging from 3 l/sec to 250 l/sec in steel tank units. The filters are
normally installed in multiple concrete tanks, the largest flow being 9,250 l/sec to-date. Retrofit into existing tanks is possible.

All units are produced to Swiss quality standards in Mecana’s factory in Switzerland, with the stainless
steel tanks and control systems manufactured in the UK by Hydrok. The Mecana Pile Cloth Media Filter
offers a superior operational performance to that of any micro-screen or micro-strainer in the market
today as it is a true filter with depth filtration being the dominant particle removal mechanism.
