Odour reduction at Berriedale plant
A project which will significantly reduce odour at the Cameron Bay Sewage Treatment Plant (STP) will reach a major milestone this month.
A biogas flare has been installed at the Cameron Bay STP, which is situated in Berriedale—next to the Museum of Old and New Art (Mona).
TasWater’s Capital Delivery Office (CDO) Project Manager Derrick Clack said the works at the plant are two-fold.
“Due to the treatment process at the plant, the site produces biogas which can be odorous,” Mr Clack said.
“The flare which we have now installed is burning the biogas to the atmosphere, by burning it you remove the odour and the subsequent harmful effects it can have to the environment.
“The flare is also completely automated which makes it more reliable. It senses the pressure inside the plant and burns off the odour before it gets released into the atmosphere.
“Now we are entering the second phase of the project which features the dewatering of the sludge at the site through the use of a rotary screw press,” he said.
“The sludge which comes out of the treatment process has odour, but we will be completely covering it up and installing ventilated bins which will control and mitigate odour at the site.”
The rotary screw press will also allow dewatering to happen more efficiently.
The works are on track for completion by the end of the year, resulting in a reduction of odour and improved environmental outcomes.
Essential services will not be disrupted throughout the course of the project.
