Magnesium Hydroxide Dosing Units
OdourPro Magnagard™ dosing units raise sewer pH to reduce odours and system corrosion
OdourPro's magnesium hydroxide dosing units raise the pH in untreated wastewater to a level that is not conducive to the bacterial processes that generate odorous H₂S gas.
Magnagard™ dosing units aid the control of H₂S gas emissions which are toxic for site workers and produce unpleasant odours at low concentration. Dosing can occur directly into a sewer flow stream or via a sewer manhole, pump station or rising main.
OdourPro's expert maintenance, monitoring and chemical delivery services ensure that your dosing unit continues to perform at its highest capacity.

Uses and applications
- Used in sewage treatment plants, rising mains and pump stations
- An alkali used to treat low pH (acidity) in wastewater systems
- H₂S levels are regulated downstream from dosing point
- Lowers the emission of H₂S gas by up to 80%
- Reduces corrosion of sewer system facilities by H₂S gas
- Ensures compliance with Work Health Safety (WHS) Regulations
Benefits of OdourPro Magnagard™ magnesium hydroxide dosing units
- Reduces odour by up to 80%
- Proven history of reliable results
- Aids eradication of suspended solids
- Efficient method of heavy metal elimination
- Allows sludge to go to landfill (no encapsulation required)
- Saves you money on sludge disposal
- Environmentally friendly
How it works
OdourPro Magnagard™ dosing units work by raising the sewerage to a pH level of 8 or above. As the chemical reaction that causes H₂S emission works best when the pH is between 6.8 and 7.2, less odorous gas is produced with a higher sewerage pH level.
Benefits to clients
OdourPro Magnagard™ chemical dosing gets to the root of the odour problem, tackling it on a molecular level to reduce odours by 80% and prevent the corrosive build-up of sulphuric acid on sewer walls. Our magnesium hydroxide dosing units, therefore, have a vital role in saving you maintenance time and money while also maximising worker safety and complying with Workplace Health and Safety (WHS) Regulations.
This treatment of sewerage also enhances the breakdown of suspended solids, aids in heavy metal removal and allows sludge to go to landfill which means you also save money on sludge disposal.

OdourPro Magnagard™ magnesium hydroxide dosing units typically include a Bredel peristaltic dosing pump, a programmable logic controller (PLC) for dosing automation, a dosing line flushing system, and a flat or conical bottomed tank with an integrated stirrer.
The best way of introducing magnesium hydroxide dosing to a system is directly into a sewer flow stream; either via a manhole, pump station or rising main.
The Magnagard™ storage tanks are typically made out of PE and are designed to suit the product's Specific Gravity (SG) of 1.5. An automatic mixer inside the storage tank helps to retain the preferred product consistency, with additional gelling control enabled with the use of a conical shaped storage tank. Regulated water flushing of the dosing line prevents blockages. Choose from 3 security options for your Magnagard™ system; a fenced compound, metal-clad enclosure or a concrete hut enclosure.
We recommend the use of a bunded unloading area for worker safety and environmental protection. OdourPro Magnagard™ dosing units require 240V power and portable water connections.
We use magnesium hydroxide in our Magnagard™ dosing units. At OdourPro, we also provide a convenient chemical supply and delivery service.
Magnagard™ magnesium hydroxide dosing units come in a range of sizes. At OdourPro, we offer an expert consultation service to help you ascertain the best treatment strategy for your site. Your dosing unit storage tank will be sized for six weeks of storage, to allow for efficient monthly refills with a safe time buffer.
Choose to upgrade to a full telemetry option for easy access to logged system data. You may also elect either an ultrasonic or pressure pad level sensing, duty or standby pumping system and your choice of enclosure material, including COLORBOND® or concrete.
Magnagard™ dosing units can be constructed inside a shipping container and tested before easy transport to the site for quick "plug and play" functionality, facilitating trial or temporary dosing.
Chemical Supply and Delivery
At OdourPro, we provide chemical supply and delivery services for magnesium hydroxide dosing units so you never run out of chemicals, and are 100% environmental and WHS regulation compliant.
Monitoring and Telemetry
Monitoring your dosing unit's performance is necessary for fine tuning the system setup and also to maintain optimal dosing levels. Telemetry allows easy access to collected data.
Maintenance and Refurbishment
At OdourPro, we believe in providing ongoing support to our clients in the form of regular preventative maintenance visits. We can also refurbish and test existing systems.
