Industries face tighter regulations regarding heavy metals rate in wastewater

This is not new, considering their impact on the environment and health, heavy metals regulations are becoming stricter and controls more frequent in Europe, North America and Asia. As a result, pressure is increasing in industrial sites to reduce the level of heavy metals in wastewater.

A mineral wastewater treatment solution allowing freshwater savings

  1. Our first job: to offer a unique and complete mineral based solution to capture a large range of heavy metals such as Aluminium, Zinc, Cadmium or Mercury from your wastewater.

  2. Our second job: to reduce plants' freshwater consumption by recycling the water and enabling reuse it in the process.

Capterall® offers sustainable and eco-responsible solutions to our customers for water treatment that have proven to be effective, reliable and competitive enabling compliance with stricter regulations.

How does our wastewater treatment work?

Which industries take benefits from Capterall® tailor made solution?


Surface treatment industries

A Single-step treatment for complex waters

Capterall® is a non-toxic solution able to efficiently capture the wide range of metals present in the wastewater coming from metal surface treatments. By solving the challenges linked to the presence of multi-metals, we aim at simplifying our customers’ wastewater treatments and enabling them to comply with discharge regulations without extra efforts.


Capterall-non ferrous metal

Non-ferrous metals

Water savings, lower environmental impact

Our customers working with non-ferrous metals need to prevent metal peaks in their wastewater treatment process. We developed an innovative semi-autonomous treatment unit capable of efficiently respond to this need. Our easy-to-use and non-labour intensive solution enables a reduction in water consumption (around 20% of the process water is recirculated), thus decreasing the cost and the environmental footprint of the facility.


Capterall-power plant

Power plants

We create customized solutions to comply with regulations

Our high level of expertise enables us to design tailor-made solutions fitting the specifics of power plants’ wastewater treatments. We facilitate our clients’ compliance to stringent regulations - including the new limits on mercury concentrations - through an easy-to-use and a one-step solution with no need for dosing system.



Chemical Industry

A solution able to deal with metals' peak concentration

We provide industrial players in the Chemical industry with a simple and non-toxic solution to treat wastewater continuously regardless of high water flow fluctuations. Capterall® 's non-labour-intensive solution will enable you to efficiently decrease the concentration of peaks at the outlet of your installation, going from 100 ppm to 1 ppm.

Case study: Solvay chemical plant in Rheinberg

The Solvay Group focuses on reducing its environmental footprint and improving its sustainability measurably. For this purpose a Capterall® installation was implemented in the Rheinberg Soda Ash and Bicarbonate plant (D) in 2018. 


Context – Micro pollutants (metals, heavy metals, PAH…) in industrial water targeted

Heavy metals consequences on public health

Heavy metals remain a major challenge for all industries. These contaminants are invisible to the naked eyes. They are transported by water and accumulate in the environment and living organisms, in the worst case causing poisonings or other serious diseases.

Solvay plant needs: reducing Hg, Cd, Ni, and Cu emissions

The gas washing of the mixture of lime kilns and coke in the wet-scrubbers used in the manufacturing process of soda ash and bicarbonate produces  wastewater. Solvay Rheinberg plant’s main contaminants present in the water are metallic contaminants, including Mercury (Hg), but also others such as Cadmium (Cd), Nickel (Ni), and Copper (Cu). Additionally, other contaminants such as Polyaromatichydrocarbons (PAH) in solid and dissolved forms have also been identified.

Successful lab test and product adaptation

Before constructing the industrial installation, the Capterall® team conducted a full audit of the current plant to understand its needs and local regulations. After running successful lab tests, the product and process were scaled-up to operate on a mobile unit onsite. After the successful onsite trials that validated operational parameters, our Capterall® Team was able to design and build the industrial wastewater treatment plant.

Low CAPEX and easy installation

Before adopting Capterall®, Solvay Rheinberg plant tested other finishing solutions like an Activated Carbon Filter (ACF). However, estimated bigger operating costs due to clogging by dust or suspended solids resulting in regular operational interventions led to its non-selection.

One of the main success factors of Capterall® is its versatility that allows to treat a large set of pollutants and be inserted as the finishing step in most types of treatment plants - all of this with only low investment.  


Requirements of the legislation:

According to the “Ordinance on Requirements for the Discharge of Waste Water into Waters” by the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety of Germany, the limitations are set as above:

  • Hg < 1ppb
  • Ni and Cd <5ppb
  • Cu <10ppb

The Hg peaks range between 10 to 50 ppb and are reduced below 1 ppb by Capterall® in a reliable manner. 

Although there is no imposing regulation for PAH, some German local authorities in DE are already demanding viability and technical studies for current stations in order to comply with future regulations.


Capterall Testimonial

“What is special compared to other products is the wide range of applications. Even for different kinds of pollution, with different kinds of challenges, we are able to develop a “tailor-made” solution.”
