3 SUCCESS CASES OF PLASTIC MEDIA BIOFILL® TYPE A, 26 YEARS IN SERVICE WITHOUT BEING CHANGED

THE MUNICIPAL WWTP OF BALSARENY AND THE INDUSTRIAL WWTP OF A TEXTILE AND A PHARMACEUTICAL COMPANIES, ALL THREE CLOSE TO BARCELONA, ARE STILL WORKING AT FULL PERFORMANCE, 26 YEARS AFTER THE STARTUP, WITH THE SAME FILTER MEDIA BIOFILL® TYPE A THAT WAS INSTALLED ON THE FIRST DAY

The filter media BIOFILL® type A installed for the projects has not needed to be replaced in any of the cases and allowed to:

  1. Eliminate the dissolved organic charge to limits that allowed to discharge the treated water to the river, meeting the regulation for specially protected areas.
  2. Reduce drastically the chemicals consumption.
  3. Reduce sludge production to less than a half.
  4. Reduce the operational costs to less than a half.

CASE Nº1.- EDAR DE BALSARENY (1989)

The treatment plant at Balsareny (Barcelona, España) was the first treatment plant that was inaugurated in Spain using the trickling filter system with a plastic media instead of a mineral one like it used to be done back then.

The treatment plant in that city is still working without any kind of problems 26 years after the inauguration, on 1989, and without needing any additional changes to the design or operation plan.

The study consisted in the essay of combining a trickling filter biological system with plastic media BIOFILL® type A and the existing physical-chemical system.

CASE Nº3.- PHARMACEUTICAL INDUSTRY (1989)

A pharmaceutical multinational industry with two production centers in Catalonia (Barcelona area) had WWTP with low features. The new environmental regulation of the Autonomous Government forced the construction of a new plant that allowed to meet the corresponding regulation. Although their discharges are made to a municipal discharge system, the high loads of the waters forced a multiple phase design in order to meet the desired values.
