Question

Explain different process of Natural draft ventilation of Trickling filter with neat sketches.

Answer 1

Answer:

A house with a natural draught ventilation system has no fan, and the air is admitted instead through valves and gaps in the structure and is discharged through ventilation ducts often built into the chimney breast. Air circulation is achieved by the temperature difference between the outdoor and indoor air.A trickling filter is a type of wastewater treatment system. It consists of a fixed bed of rocks, coke, gravel, slag, polyurethane foam, sphagnum peat moss, ceramic, or plastic media over which sewage or other wastewater flows downward and causes a layer of microbial slime (biofilm) to grow, covering the bed of media.
