Hel-X Bio Carriers in biofilm and mass transfer processes

Hel-X biocarrier are specially developed for use in biofilm processes. They are used successfully around the world in municipal and industrial wastewater treatment, aquaculture / aquaponics, and ornamental fish farming as growth bodies or fillers. You will also work in numerous other areas of process engineering as fillers in mass transfer processes.

The Hel-X Flake is a further development. The extremely large specific surface of this product results from the porosity of the material.

All Hel-X products are manufactured in Germany according to our quality and environmental standards.

Füllkörper

The name Hel-X characterizes the circumferential spiral or helix, a product property that ensures high mechanical stability with at the same time very good flow and a high specific growth area. The biofilm is optimally supplied with oxygen and nutrients.

Gerd Röder Retires

After nearly five decades of tireless dedication, Gerd Röder is retiring well-deservedly. Since 1975, Mr. Röder has been employed at Christian Stöhr GmbH & Co. KG in Zeyern.

He began his career as an industrial mechanic and quickly demonstrated his skills and commitment. Over the years, he advanced and eventually took on the role of plant supervisor. In this position, he was instrumental in ensuring and advancing the production of curlers and HEL-X growth media for biological wastewater treatment. His expertise and dedication significantly contributed to the company’s success.

The managing directors, Michael Stöhr and Henry Stöhr, recognize Gerd Röder as a valuable asset to the company and sincerely thank him for decades of successful collaboration. “His work and dedication have left a lasting impression and have sustainably shaped the company. We wish him all the very best and much joy in his retirement, facing new challenges and enjoying periods of relaxation,” said the managing directors.

The entire team of Christian Stöhr GmbH & Co. KG bids farewell to Gerd Röder with great thanks and best wishes.

Hel-X Flake 30

Ideal for heavily loaded Sewage and compact systems

Due to its high porosity, the HEL-X Flake 30 made an extremely large area available for biomass growth. This allows very high degradation rates in the smallest of areas.

In the pores of the HEL-X Flake 30, the biomass is protected from abrasion. At the same time, the flat geometry allows an optimal supply of oxygen and nutrients.

The HEL-X Flake 30 is the optimal solution for heavily polluted wastewater. The highly porous, compact structure enables high space reduction rates for high cleaning performance on a small area. In the pores, the biomass is protected from the shear forces, at the same time the surface of the chip is cleaned by the shear forces, so that the supply of the immobilized biomass with nutrients and oxygen is ensured.
