Membrane bioreactor

Highest level of effluent standards The effluent produced by the EcoprocessTM MBR can meet the strictest quality requirements for the discharge of treated wastewater, including disinfection, nitrogen reduction and phosphorus removal. The treated wastewater is suitable for re-use in applications where it is permitted.

Compact modular designRequires up to 75% less installation area than that required by conventional treatment technologies and can be easily integrated into the local environment.

ReliabilityThe next generation of multi-layered membrane technology utilized in the EcoprocessTM MBR combines the benefits of flexibility and high surface area, as seen in hollow fibers, with the durability and strength of flat sheets. This versatile design enables the highest level of energy conservation and long-term reliability.

Energy efficientKey design features allow for efficient and optimal processes. Fine bubble diffusers are used for membrane scouring, as well as cost effective biological treatment.

activated sludge. The submerged membranes ensure ultrafiltration and act as a physical barrier that retains pathogenic organisms and suspended solids. Treatment optionsReduction of total nitrogen: EcoprocessTM MBR can be sized to ensure denitrification.Total phosphorus elimination: A dosing unit is added to EcoprocessTM MBR system.

DischargeThe high quality effluent is suitable for direct surface discharge. The effluent can also be re-used when environmental standards permit it.

The EcoprocessTM MBR membrane bioreactor includes BIO-CEL® ultrafiltration membrane modules manufactured by Microdyn-Nadir. For over 40 years, Microdyn-Nadir has been designing and manufacturing membrane technologies and thousands of high-performance systems use their membrane ultrafiltration processes.

Primary treatmentThe primary treatment consists of a first phase decanting (a septic tank, for example) or appropriate mechanical straining.

Equalization tank (when required)An equalization tank may provide a more economical process flow when major flow variations are involved.

EcoprocessTM MBRThis system consists of a biological process and a filtration process. The fine bubble aeration system provides the oxygen needed to biodegrade oxidizable pollutants that are converted into

EcoprocessTM MBR treatment system

Cost effective treatment technologyThe pores on an ultrafiltration membrane are 1 500 times smaller than the diameter of a human hair. This low molecular weight cut-off provides a physical barrier that ensures process performance and stability.

Automated disinfection and levels of 0.1 mg/L of phosphorus can be achieved.

The unique configuration of the EcoprocessTM MBR provides the smallest required space to treate effluent volume ratio.

High performance, compact designs and long-term reliability are key benefits of the EcoprocessTM MBR.
