|
Raw sewage is pre-digested in a septic tank, or with the ‘full
kit’ plant, in Lilliput tanks, by anaerobic bacteria converting
most of the complex organic matter into simple but toxic chemicals
|
| |
| The solution produced is pumped into the Bio-reactor, which contains
randomly packed media. Air is introduced and aerobic bacteria oxidise
the harmful, malodourous chemicals converting them to safe, ‘clean’
salts. |
| |
| At times of surge flow excess effluent is returned to the septic
tank to ensure complete treatment. |
| |
| If discharge is other than to irrigation, a clarifier is used to
extract excess solids and return them to the septic tank. |
| |
| The final stage of treatment is disinfection, which ensures that
any pathogens are removed. |
