ZEN Active Media filters along with our STF series of self-cleaning and auto backwash filters are custom
engineered for critical applications in Cooling Water circuits in process and side stream filtration to meet the
requirements of Turbidity, TSS, Microbiological Removal and Oil in Water. The prime objective of every
system is to ensure point of entry filtration, water quality as per customer requirements and maintenance of
high standards of Water Management/Mass Balance by less water wastage, no or minimum chemicals, dirt
rejection at source and maintenance of high level of circles of fine filtration in the plant.
The solution also ensures Effluent Discharge Norms laid by Pollution Board on BOD, COD and TSS on most economical basis of treatment with minimum or no maintenance cost for next 7 to 10 years.

Silica sand is a good filtration media but it also makes a perfect home for growing
bacteria. Bacteria are required in bio-filters and slow bed sand filters but in rapid
gravity or pressure filters, bacteria causea biodynamic mechanical instability of
performance. Bacteria stick onto the sand by secreting an alginatejelly. The alginate
forms a film that provides a home for the bacteria and even protects them from
oxidation by chlorine. The problem is that the alginate glues the sand together and
blocks the bed,especially during the summer months. Bacteria can double in biomass
every 30 minutes, the alginates secreted by the bacteria increase the Delta P and can
half the length of the run phase. The alginates also glue the sand grains together and
promote the development of wormhole channeling. ZEN active media eliminate formation of bioflim & channeling
