Your water ecosystem green and circular?

Purify your wastewater with FerSol® and you’ll get the job done.

Keeping costs in check and meeting regulations can go hand in hand


Strict requirements for water quality

Discharging to surface water is expensive because of the pollution levy on substances such as phosphate.

In greenhouse horticulture, the emission of fertilisers and plant protection products will have to be close to zero by 2027.


Limited possibilities for reuse

Circular use of water is difficult because the hazardous chemicals that are used for water purification are hard to remove. In addition, over time, the pH and sodium levels in the water increase to a harmful degree.


Rising costs residual water treatment

The purification of wastewater is expensive due to energy intensive procedures with UV and ozone, as well as the frequent discharge of sludge.

You will achieve these results with FerSol®

Decrease phosphate levels with 90%

With FerSol®, you remove 90% of phosphate from the residual water. FerSol® replaces several hazardous chemicals from the purification process, such as chlorine and caustic soda. The process also reduces the need for nitric acid.

Use less energy

FerSol® purifies water efficiently and reduces sludge. It replaces energy intensive and costly procedures, which use ozone and UV. Save energy and costs at all stages of the industrial process: from purification to discharge.

Create less sludge

FerSol® densifies and reduces the amount of sludge. It is the most powerful oxidant in the world and strongly binds the particles of the residual product together.

ATP reduction from 858 RLU to 55 RLU

Thanks to FerSol® (Ferrate(VI) in solution), we have reduced our ATP values from 858 RLU to 55 RLU. That is far below our target value of 200 RLU: a promising result!

Test our product FerSol®

And discover how FerSol® changes your wastewater treatment into a green, efficient and circular process. No strings attached!

Find the solution for your wastewater and let us analyse it in the Ferr-Tech WaterLab. We will identify the contaminants in your wastewater, to determine how FerSol® -Ferrate(VI) in solution- improves your process.

This gives you valuable insights into how FerSol® makes your water purification process green, efficient and circular. Moreover, we would be happy to discuss other challenges in the field of water treatment. We dare you to challenge us!


1. Share wastewater sample

Give us a 20 liter sample of your raw wastewater. We will treat the water with FerSol® and work towards the best results for your process.

2. Improve your process

Based on the analysis, we will create a proposal for a green, efficient and circular water process.

3. Implement easily

Finally, we will demonstrate how you can easily apply FerSol® in your current water treatment system.

Wastewater purification in greenhouses

The greenhouse horticulture sector faces a challenge. By 2027, the emissions of fertilisers and crop protection agents must be virtually zero. In addition, a purification obligation has been in force since 2018: at least 95% of the crop protection agents must be removed from the water before it may be discharged. This means that circular water provision is more relevant now than ever. How do you achieve this in a sustainable and economical way?
