THE
BIOSEPTIC PROCESS
The BioSeptic system is a compact
sewage treatment plant that safely processes all household wastewater
and recycles it as clear odourless water to irrigate the garden.
For the environmentally responsible person this means that the wastewater
is treated and recycled on the property where it is produced rather
than moving the waste problem to a town sewage treatment plant.
The BioSeptic process begins when all wastewater from the kitchen,
toilets, bathroom and laundry drains into the septic tank. The solid
waste settles in the septic tank and naturally occurring anaerobic
bacteria slowly break it down.
The wastewater overflows into the aeration tank where air is diffused
into two separate aeration chambers to create aerobic bacteria.
These quick acting bacteria reduce the sewage to carbon dioxide
and water. Because aerobic bacteria breathe oxygen there is no odour.
Finally, a small amount of chlorine is added to kill any pathogens
that have survived the aeration process. The treated water is then
suitable to irrigate the garden.
Testing for Accreditation by the Department of Health, New South
Wales, Australia, showed that the Performa removed:
•
97% of the organic waste (BOD5)
• 98% of the suspended solids and
• 99.99% of the faecal coliforms (indicators of pathogen
removal)
• 80% of the ammonia |
Plants
are nature’s best method to take up the nutrients that must
be prevented from flowing into streams and rivers, so it is important
to have plenty of trees and shrubs to transpire (soak up) the treated
water.
BioSeptic owners are able to enjoy a beautiful garden that is kept
green and fertile throughout the year.
