We seek to continuously improve our sanitation systems through the gathering of systematic feedback from our engineers in the field.
Our sewage treatment know-how is one of the key pillars of the expertise we provide to support you to reach your sustainable development goals

The first stage of the water treatment process focuses on separating suspended solids (SS) from wastewater. We remove 70% to 90% of these materials through our flocculation / coagulation / settling and flotation processes – with the injection of chemical reagents depending on the degree of purification required.

The secondary treatments then use advanced biological treatment methods, leveraging the ability of certain bacteria to eliminate dissolved pollutants contained in wastewater – such as carbon, nitrogen and phosphorus pollutants. These biological treatment methods are sometimes associated with the use of chemical reagents when treatment goals are high.

This final stage looks to remove any remaining dissolved solids from purified water and disinfected wastewater so that the treated water can be reused for other purposes.

The pollutants eliminated during treatment operations become sludge, and recycling and recovering this substance is one of our specialities.

To remove any unwanted odours, while also guaranteeing compliance with air quality regulations, we ensure polluted air extraction continuously takes place throughout the water treatment process. The extracted air is then treated appropriately before being expelled.

We can tailor our offering depending on your project, from installing individual engineered solutions or packaged plants to complex projects. Our goal is to develop sustainable and innovative solutions that balance cost-effective technology with protecting the environment.

The Moving Bed Biofilm Reactor (MBBR) solution by AnoxKaldnes^Ⓡis a biological process where biofilm grows on carriers suspended in wastewater. This biological wastewater treatment and biological water treatment process treats pollutants in a cost-efficient way and it is used across almost all and industrial market sectors.
