Sand Filter Lifespan

The Ecosafe Sand filtration treatment process is biological, and so the Sand Filter has an unlimited life.

The action in the Sand Filter is not a straining process as the work ‘filter’ may suggest. It operates as follows:

  • Prior to any contact with the Sand Filter, in Ecosafe’s Primary Tank, the wastewater initially undergoes a “separation” of solids & water by anaerobic bacterial action.
  • As the wastewater gravitates through the Sand Filter bed, it makes intimate contact with the microbiological film which naturally develops on the surfaces of the sand grains. This microbiological action digests the organic content of the wastewater.

Providing the system is not grossly mis-used by blatant neglect etc. the process is bio-sustainable and ‘clogging’ never occurs.
