HEL-X Flake 30 and Hel-X Flake Pro
Ideal for heavily polluted wastewater and compact systems
Due to the high porosity, Hel-X Flake 30 and Hel-X Flake Pro provide an extremely large inner surface area for growth of biomass. This allows very high removal rates even for small tank volume.
Inside the pores of the Hel-X-Flake 30 and Hel-X Flake Pro the biomass is protected from shearing forces. At the same time, the surface of the chip is cleaned to ensure high mass transfer rates of oxygen and nutrients.
Development
Hel-X biocarriers in biofilm processes and mass transfer processes
The success of conventional carriers for use in MBBR or IFAS allowed other applications to be investigated. High concentrations of BOD and COD need to be reduced in many industrial applications created the demand of larger active surfaces for carriers. To meet the needs of our customers, the development of the high-performance Hel-X Flake carriers started more than 15 years ago.
The high-performance carriers Hel-X Flake 30 and Hel-X Flake Pro are made of HDPE just as the conventional Hel-X carriers. However, the active surface results from a special pore structure of the plastic body.
Microorganisms grow inside the pore volume. Nutrients and oxygen are provided by mass transfer to the carrier surface and diffusion inside the pore volume.
The Hel-X Flake Pro is a recent development. This carrier is no longer flat but has a special wave profile. This shape reduces the contact area between the individual Hel-X Flakes and as well to other surfaces resulting in optimal fluidization of the high-performance carriers. In addition, the wave structure provides an enlarged active surface for growth with microorganisms.
The Hel-X Flake PRO is protected by patents.
The HEL-X Flake 30 has been in production since 2019. With a diameter of 30 mm, this is significantly larger. It is characterized by its flat structure with a thickness of 1.1 mm.
The HEL-X Flake Pro has been in production since 2022. Due to the profiled shape, the Flake Pro has a significantly larger surface.
Technical data
The specific surface was confirmed by measurements at well-known universities and research institutions.
In order to ensure the constant quality of the flakes high-performance biocarrier, we prefer to use virgin material HDPE white.
