ADVANCED AND ENVIRONMENTALLY SOUND BIOLOGICAL PROCESSES

Tecn.A. builds biological waste water treatment plants of the MBR type (membrane bioreactors) which, thanks to the use of membranes instead of traditional static decanters, make it possible to maintain a very high concentration of biomass in the biological plant, with an extremely clear effluent, protected from any bulking phenomenon (floating sludge).

With MBR systems it is possible to separate the activated sludge, regardless of its concentration, from the purified water. The active sludge is recirculated into the oxidation tank, while the clear permeate is discharged.

CONSTANT QUALITY OVER TIME

The application of biological membrane plants in wastewater treatment has the following advantages over traditional solid-liquid separation systems:

• The membranes which are used accept higher sludge concentration gradients, without affecting the quality of the discharged water.
• Filtering membranes constitute an absolute barrier against micro-organisms and suspended solids, also filtering organic molecules that have not been knocked down by the biological oxidation process.

The high concentration of total solids (TS) increases the stability of the system, making it more resistant to toxic agents and more flexible than pollutant input loads.

MBR SYSTEMS FOR THE FOOD, COSMETICS & PHARMACEUTICAL INDUSTRIES

Thanks to MBR technology, it is possible to work on systems already in operation, enhancing them and improving their efficiency without any new structural intervention.

In practice, an MBR plant consists of an aerated tank similar to that of an activated sludge plant, followed by a membrane filtration stage instead of a settling stage.

These plants are particularly interesting for severe applications, such as discharges from the food, cosmetics and pharmaceutical industries.
