Wastewater arrives into the primary septic tank by gravity from the building. The solid matter will settle on the floor of the primary septic tank to be “degraded” by anaerobic bacteria. The suspended (floating) matter such as fats and oils will form a “crust” at the surface. The outlet of the primary septic tank is fitted
with an approved biological filter to prevent suspended matter from passing through to the second (treatment) compartment.
Xylit Trickling filter
The pre-treated and filtered waste enters the Xylit filter bed by gravity into the distribution device “tipping trough”. The tipping trough fills and alternately disposes into a network of perforated pipes (spider) to evenly distribute influent over the Xylit filter bed.
The “pre-treated” waste water slowly trickles through the Xylit media, where the population of digesting bacteria develop to digest and purify the waste liquid.
Oxygen is supplied to the filter by a network of 100mm diameter pipes. This is achieved with No power.
Distribution
The treated water leaves the filter by gravity from the floor of the filter tank into the dose flout (no power) or pump chamber 6. The treated water is gravity dosed or pumped into the land application (disposal) area
The land application area is chosen for its potential for gravity or pumped distribution. The treated waste can be distributed through drip irrigation, LDPE or UPVC piped trenches.
The X-perco has a small battery operated alarm that will activate in the unlikely event the water level.
