Based on more than 10 years of experience with MBBR systems, Envista developed the Enchip™ in 2019 which nowadays forms the core of Envista tech‘s fluidized bed process called Enchip MBBR Technology™.
Enchip with biofilm
Carrier retention screen
Design & application
The Enchip MBBR Technology™ is a proven biological treatment process with numerous WWTP operators world wide.
A lot of plants using the Enchip MBBR Technology™ have been designed and engineered in basic and detail by Enchip’s high-qualified engineering team.

for highest performance in biological water treatment
best possible removal performance
remarkably stable processes
ideal for easy retrofit & upgrade
high grade quality
long life material,
no wear best price-performance ratio
Removal rates of EnChip are up to 10 times higher than with “conventional” carrier.
High quality pore system
The EnChip is a high-performance MBBR carrier and provides a protected active surface area of > 5,500m²/m³ for the immobilization of micro-organisms which are in charge of the different biological water treatment pro-cesses. Its application is characterized by extremely high removal rates and reliable process stability.
Diffusion depth from each side approx. 0.5 mm
The pores of the BioChip are permanently filled with active biomass since substrate and/or oxygen can diffuse into the biofilms down to a depth of approx. 0.5 mm on both sides of the chips.
Cross section Enchip
Enchip is used in the following biological treatment processes:
Enchip with planctomycetes
Advantages of Enchip:
protected active surface: > 5,500 m²/m³
high quality PE material (virgin)
optimal pore system and –structure
less carrier volume needed
small footprint system
thin, controlled biofilms
optimal diffusion of O2 and substrate
easy upgrading or retrofitting ofexisting plants
large diameter (30 mm; 1“)
no abrasion & wear
