Omya Neutramaxx  

Safe, stable, cost-efficient neutralization for industrial and municipal wastewater. 

Milk

Replace caustic soda and other milks of lime  

Omya Neutramaxx is a concentrated, highly reactive milk of lime for wastewater neutralisation and pH control. It can directly replace caustic soda and other milks of lime in industrial and municipal wastewater treatment, improving process efficiency while reducing risks for both operators and the treatment process.

Frequently Asked Questions

Omya Neutramaxx is a ready-made product that can be used as a direct replacement for 50% caustic soda solution. It is safer to use than caustic soda and offers greater operational efficiency for both neutralization and precipitation processes.

Omya Neutramaxx has a much longer shelf life than other liquid limes because of its low viscosity and stable rheology profile which does not increase over time.

While conventional milk of lime products often require regular agitation or recirculation to help prevent settling during storage, Omya Neutramaxx remains free-flowing and maintains a homogeneous suspension in unstirred storage conditions for more than three months. This helps simplify storage and handling while reducing maintenance associated with settling and equipment clogging.

Omya Neutramaxx maintains a homogeneous suspension for more than 3 months in unstirred conditions without mixing or recirculation. This exceptional storage stability supports reliable dosing, simplifies storage and helps reduce maintenance associated with settling and clogged equipment.

Municipal and industrial wastewater plants should evaluate neutralisation capacity, compatibility with existing dosing infrastructure, operator safety, storage stability and downstream sludge handling. Omya Neutramaxx can be direct-dosed into wastewater streams without additional make-down or powder dosing systems. Its neutralisation capacity is equivalent to 50% caustic soda, while its faster settling and improved dewatering properties help reduce sludge handling requirements, supporting more efficient operations and lower wastewater treatment costs.

pH control stability depends heavily on dosing consistency, and dosing consistency depends on how stable the product is in storage. A product that settles or thickens over time can cause uneven dosing and unwanted pH fluctuations. 

Omya Neutramaxx maintains a homogeneous suspension without settling for more than 3 months in unstirred conditions, supporting more predictable dosing without the agitation or recirculation that other liquid limes require. Its non-corrosive, non-dangerous-good classification also reduces handling risks during storage, transfer and repacking.

Omya Neutramaxx improves operator safety through its non-corrosive classification, non-dangerous-good status and liquid, ready-to-use formulation. Unlike caustic soda, it is not classified as a dangerous good under the United Nations Recommendations on the Transport of Dangerous Goods. Unlike traditional lime products, it eliminates the need to handle dry lime or quicklime. This reduces risks during storage, transfer, repacking and dosing operations.

Omya Neutramaxx helps reduce wastewater treatment costs through faster settling, improved dewatering and better valorisation of waste streams. Its lower exposure to price volatility compared with caustic soda also supports a more predictable operating cost base.
