SALHER - Model CVD -WWTP with Trickling Filter
The vertical treatment plant with settling – digestion chambers, biological filter and grease chamber CVC-D is a GFRP equipment with orthophthalic resins for the elimination of 70 – 80% of organic matter (BOD5) and 65 – 70% suspended solids (SS). This set of treatments includes settling, digestion, biological filter and separation of floats with a plastic filling material with a high hollows rate (95%) and a high specific surface area (140 m²/m³).
The horizontal treatment plant with settling – digestion chambers and trickling filter CHC-D is a GFRP equipment with orthophthalic resins for the elimination of 70 – 80% of organic matter (BOD5) and 65 – 70% solids in suspension (SS). It includes a primary treatment through settling-digestion, a secondary treatment through trickling filter with a plastic filling material with a high hollows rate (95%) and a high specific surface area (140 m²/m³).
Among our WWTP by biological filter, we have the horizontal treatment plant with settling – digestion chambers, trickling filter and a secondary decanter CHCD-D, a GFRP equipment with orthophthalic resins for the removal of 80% of solids in suspension and of 70-80 % of organic matter (BOD5). This depuration option contains a primary treatment by decanting – digestion, a secondary treatment by biological filter, a compact secondary decanter, all with plastic filler material with a high hole index (95%) and a high specific surface area (140 m2 / m3).
Finally, the biological filter or trickling filter with reference CVC-FB is a GFRP equipment with orthophthalic resins used for the elimination of 80-90% of organic material BOD5. Inside, a secondary treatment is enclosed through trickling filter with a plastic filling material with a high hollows rate (95%) and a high specific surface area (140 m²/m³).
