Improve water quality & treatment performance with natural mineral products.​

Municipal Waste Water​

Municipal waste water treatment facilities face tough challenges in dealing with the unpredictable nature of wastewater from populated regions. The dynamic nature of municipal wastewater means the plant itself must be flexible to follow such dynamics, in order to respond appropriately, and prevent any negative impact to the environment.


Omya Optical®​ provides for an efficient and stable activated sludge treatment operation thereby ensuring a clear (low turbid) overflow, stable flocs (improve settling), consistent sludge extraction and improved dewatering.​

Omya Optical®

Naturally enhanced Activated Sludge Process

Omya Optical® supports the role microorganisms have in the activated sludge process to convert dissolved and particulate organic matter (measured as biochemical oxygen demand, BOD), into cell mass.

Omya Optical® improves the formation of flocs in the activated sludge process and provides for better floc settling, improved sludge index and sludge blanket as well as improved sludge dewatering properties.

Omya Optical® enhances the growth of nitrifying and denitrifying bacteria thereby also reducing the risk of filamentous bacteria growth (foaming sludge).

Biological and chemical reactions affect the pH and where Omya Optical® establishes a stable pH usually between 7.0 – 8.5 as well as providing for the required buffer capacity to avoid drastic pH changes consequently allowing for a stable microorganism growth and survival.


  • Stable pH – no overdosing, high buffering capacity
  • Improved floc settling performance
  • Reduced floating and bulking sludge
  • Enhanced Bacteria growth
  • Improved sludge dewatering

Industrial Waste Water​

Industrial waste water presents unique challenges to the cleanliness of natural waterways. Not only must the water itself be treated to a standard that will pose no environmental risk, but the chemicals and processes used to treat it must also be environmentally neutral and sustainable.​

​​ Omya Neutrasorb is a very efficient acid neutralizing non-hazardous, natural fine grinded Calcium Carbonate. It is used in industrial neutralizing applications to replace caustic or lime. It does not form scales an d reduces maintenance costs.

Efficient Neutralization of Industrial Waste Water

Often industrial waste waters are acidic coming with a pH of 2 – 5. Neutralization is therefore an important process step required before other downstream water treatment processes. For biological processes to run stable and efficient the pH after neutralization should be ideally between 6.0 – 8.5.

Omya Neutrasorb allows is a very efficient acid neutralizing chemical based on natural fine grinded Calcium Carbonat.


Omya Neutrasorb has following application benefits over other neutralizing chemicals such as burnt lime or caustic soda:

  • Fast neutralization – very stable pH – no overdosing possible
  • No clogging and no scaling of silos, slakers and pipes compared when using burnt lime
  • Nonhazardous safe chemical reducing the risk profile of the industrial site
  • Facilitates safety training and procedures for spills and accidents
  • Transport and storage without special safety measures
  • Avoidance of sophisticated circle line concepts, valve designs and make-down stations
  • Significant reduced downtime and cost due to reduced maintenance requirements

Omya Neutrasorb quickly neutralizes and buffers industrial waste waters.
