Reducing odours and improving irrigation effluent at a private wastewater treatment works
The treatment works needed to improve the biological process without rebuilding the plant.

Project overview
Site challenge and treatment summary.
The treatment works needed to improve the biological process without rebuilding the plant.
- Initial problem
- A privately operated wastewater treatment plant discharged treated water into a dam used to irrigate a golf course, with poor clarity and strong sewage odours reported.
- Baczyme product used
- Baczyme Sewage Liquid+
- Dosage
- A dosing station was installed after the wastewater-screening stage and before the aeration and digestion tanks, reportedly dosing 1.5 L of Baczyme Sewage Liquid+ into approximately 1.5 million L of raw sewage each day.
- Treatment period
- One-month observation period
Site conditions
What Baczyme was responding to.
- Reported plant flow was approximately 1.5 million litres per day.
- Residents complained about strong sewage odours from the treatment works and irrigation system.
- Effluent was discharged into a dam used to irrigate a golf course.
- Effluent was reported as not sufficiently clear before treatment.
Treatment objectives
What the programme aimed to support.
- Reduce sewage odour
- Improve effluent clarity
- Support irrigation-water quality
- Accommodate the site's wastewater load
Before and after
Reported project progression.
These notes summarise the before-and-after information available for this specific Baczyme project.
Baczyme reported odours disappearing within approximately two weeks and dam visibility improving within one month.
Reported outcomes
Baczyme reported that foul odours disappeared within approximately two weeks and visibility in the irrigation dam improved from zero to approximately two metres within one month.
The reported capacity increase, effluent improvement and irrigation suitability require supporting flow records and laboratory results before being used as verified engineering-performance claims.
Test results or documents
Baczyme states that its characterised microbes allowed a 50% increase in raw-sewage inflow while releasing better-quality effluent. This claim should only be published after plant-flow records and full test data have been verified.
Project significance
Why this project matters.
This is one of Baczyme's strongest B2B case studies because it demonstrates integration into an existing treatment process at a reported flow of approximately 1.5 million litres per day.
