FFS processes wastewater into ultra clear liquid and strong flock. It is a 'separation pretreatment'. First use FFS, then separate with standard solutions (flotation, decanter, press, etc.) the FFS effluent is higly suitable for membrane filtration, producing reusable water. FFS is an electrochemical process so it overcomes all issues of biological treatment. And with the sludge easily pressed to higher Ds content it offers you savings on all fronts.

Our goal is to contribute to progress and create disruptive solutions for global issues, such as water scarcity.

As an ‘innovation architect’ it is our strategy to cooperate with experts in the fields of manufacturing, sales and service.

Our developments are IP secured or patented. 

PureWaterWell focusses on R&D and has reliable partners who manufacture FFS and realize your project. They will select the best possible combination of treatment steps for an environmentally friendly solution with optimal TCO. Contact us for more information here.

FFS is very versatile

FFS Tannery

Typically 10 m³/hr tannery wastewater is treated with 1 FFS system module. 

A tannery wastewater configuration can be: FFS + cloth filter + chamber filter press + MF/RO filtration.

A game-changer for municipal
and industrial wastewater treatment

Innovative Wastewater Technologies

FFS ForceFieldSeparation™

FFS for (decentral) municipal treatment plants 
FFS for many industrial applications


FFS Food

Slaughterhouses, breweries, distilleries, etc. use a lot of water, often from their own well. Due to water scarcity, water reuse will have to replace the well. FFS results in reusable water at affordable costs.

A slaughterhouse wastewater configuration can be: FFS + DAF + belt press + NF/RO filtration.

FFS + Flotation

Thousands of DAF units are now active to treat industrial wastewater. FFS increases efficacy of DAF separation and sludge processing. The efficacy of RO filtration increased. Water reuse has become a viable option.  

FFS Hospital

FFS is tested to remove medicin particles, viruses, etc. at the hospital to prevent them flowing into the sewage infrastructure. 

FFS Chemical

Wastewater from galvanizing plants is almost impossible to treat with biological systems. FFS can process most chemically polluted streams very well. 

FFS Retentate

FFS is tested to process the Reverse Osmosis brine, the filtered particles that normally must be disposed of at high costs.


Extensively Tested

ForceFieldSeparation™ is based on using electrical and chemical force fields to produce a  highly reactive liquid for intense coagulation, flocculation and oxidation. It produces a strong flock that is easy to separate and to dewater to high dry matter content, reducing costs significantly. 

FFS systems can pretreat even the most difficult streams such as leather tannery wastewater, textile dyeing plants, manures, galvanizing effluent, etc. 

The FFS effluent produces very little membrane biofouling, giving you high flux and very few membrane cleaning cycles (CIP).
