Wastewater technologies
We make wastewater systems perform better.
More sustainable.
Cheaper.
We are the inventors of
the ‘Pre-Coagulant’
PWW precoagulant
Our unique Pre-Coagulant is water-based and produced in-situ.
Dosed before standard coagulants, more COD, N and P is captured in floc.
For optimal pollution reduction, we have designed the XSeppt system.
A new sustainable technology is here.
Our brands
Industrial treatment step.
Capture more pollution.
Then efficiently produce new water using our membrane filtration.
A must-have for closing the loop.
XSeppt significantly reduces the pollution level of industrial DAF or biology as pre- or post-treatment
Municipal treatment step.
The perfect RO pre-treatment.
Subsequent RO filtration removes 100% PFAS. Safeguard public health. Have new water as a revenue.
XSeppt+ captures contaminants in municipal effluent. The most effective biology post-treatment
A high-quality bio-coagulant.
Replace the hazardous ferric chloride or PAC. This is a 100% nature-based and very safe product. Let’s
use the power of nature.
Paxos is the best sustainable high performance bio-coagulant available now
Are you ready for the future? We are…
Water is life.
It is our challenge to design and provide sustainable products that contribute to solving the ever-increasing water issues. This is our mission.
Using our 30-year experience and creativity we contribute to a more sustainable world. This is our vision.
XSeppt closes the loop
XSeppt systems perform a new chemical process that captures more pollution in floc than any other system.
This reduces costs. Even better, now you can efficiently produce reusable water. Making new water makes your company more sustainable and future-proof.

Decentral systems
XSeppt+ systems have a small footprint and exceptional capability to remove COD, N and P in seconds.
Existing WWTP’s benefit from having an XSeppt pre-treatment to give the plant more capacity. Or as post-treatment, to ensure that N is reduced and effluent norms are met.
A solution for water scarcity is our SUWR Sustainable Urban Water Reuse Concept. Using XSeppt hubs, we bring water to the people!
Nature at work
With current sustainability goals, the search for nature-based chemicals has started.
Paxos is a renewable, 100% biodegradable, safe, and highly effective coagulant in powder form. Replace hazardous Fe- and Al-coagulants, spend less, and use the power of nature.
Wastewater Biocoagulant
The final step
Xseppt is available with high-recovery membrane filtration units. Proven technology. Steady results. An unbeatable team.
High flux. High recovery. There is no better combination for water reuse.
Buy wisely…
Wastewater technology is a ‘capital good’. Our solutions bring more value at low Capex.
We reduce Opex and TCO. Easier to control than biologies. Yes, ROI is under 3 years.
Space is valuable. XSeppt is ‘small’. Easy to install skids. Optionally in containers.
Are you prepared for the future restrictions or fines? Water reuse becomes a must… Let us help.
