Waste and wastewater management

The waste sector is an innovative one, continually seeking better ways to recover and recycle products and by-products after use. Desotec’s full-service sustainable filtration systems enable companies to do their job while keeping air fresh, purifying biogas, and ensuring wastewater is safe for discharge or reuse.

Waste and wastewater treatment

The waste and wastewater management sector is key to meeting European sustainability targets. As legislation tightens and technology advances, we could aim for a zero-waste future.

This sector encompasses a series of processes:

  • Collecting, sorting and storing waste.
  • Composting green waste and upcycling them into biogas.
  • Recycling plastics, metals and batteries.
  • Wastewater treatment plants (WWTPs).

Desotec’s sustainable mobile filters provide simple yet effective purification solutions for air emissions, process gases, and industrial wastewater, supporting this sector in controlling odours and achieving its sustainability goals. 


Air and gas purification in the waste sector

For landfill sites and recycling centres, keeping air fresh is a top priority. Desotec makes it easy, with modular filtration set-ups adapted to your needs.

Our filters protect human health and the environment by treating volatile organic compounds (VOCs). Many of these VOCs are also odorous, as are emissions from WWTPs, which contain mercaptans, hydrogen sulfide (H₂S), and ammonia (NH3). Activated carbon filtration can remove all these components, thus keeping the air safe and fresh for workers and those living nearby.

Desotec filters also treat biogas recovered from organic waste. Before biogas is fed into combined heat and power (CHP) engines, our filters remove siloxanes to prevent equipment damage. By eliminating VOCs, terpenes, H₂S, and NH3 from biogas, our activated carbon enable its upgrading into biomethane.

Desotec’s sustainable mobile filtration solutions make these processes simple and circular. We take back saturated filters for recycling and install new ones to keep your site functioning smoothly.

Waste management companies are at the forefront of global efforts to use our planet’s natural resources wisely. Desotec full-service sustainable mobile filtration solutions can help you meet your purification needs.

Wastewater purification

Desotec filters remove adsorbable organic halogens (AOX) and reduce chemical oxygen demand (COD) from wastewater. This allows companies to keep natural waterways aerated and healthy and meet WWTP acceptance limits.

Leachate water from scrapyards and landfill sites contains contaminants such as hydrocarbons from cooling liquids in fridges, COD, oil components, polycyclic aromatic hydrocarbons (PAH), and polychlorinated biphenyl (PCB). Our filtration removes these pollutants to keep soil and groundwater clean.

Our filters also reduce chemical residues and chlorinated cleaning products released by different activities such as:

  • Rinsing waters.
  • Preparing plastics for recycling.
  • Cleaning storage tanks and production facilities.

Treatment brings down emissions to the limits set by the local WWTP, meaning that wastewater can be safely discharged to the sewer.

How we help you

Desotec sustainable mobile filtration solutions

At Desotec, we support waste and wastewater management companies with simple mobile activated carbon filtration solutions. Our service covers everything, from filtration needs analysis to waste handling.

Our modular, plug-and-play filters may be used on their own, or with other technologies as a pre-treatment or polishing solution.

We transport filtration waste in closed units away from your site. All molecules are completely destroyed and, where possible, carbon is reactivated, giving you a circular solution that boosts your business profits and environmental responsibility. Where reactivation is impossible, waste is treated safely. Our R&D team is continually seeking new treatment solutions to further enhance sustainability.

For our new recycling plant, we needed a reliable wastewater treatment process. Desotec helped us set up the best possible installation. We are very pleased with the result.
