Anaerobic Biological Processes

Anaerobic Biological Processes

Following nature’s example:
The copying of nature’s fascinating capabilities as perfectly as possible and their harnessing for technical applications represents a source of innovative renewal processes. Nature shows us in an exemplary manner that the organic matter contained in water can be converted biologically into energy-rich, and thus exploitable, biogas by micro-organisms in an oxygen-free medium. Therefore, the natural anaerobic degradation process constitutes recycling at its best.
As compared with conventional aerobic treatment methods, the anaerobic process offers significant benefits:
Key Features
 Very low energy consumption.
 Generation of exploitable biogas.
 Minimal sludge production.
 ◾Minimum space requirements.
 ◾Low nutrient requirement.
Space-saving, emission-free and profitable
The ever-stricter stipulations confronting industry with regard to the use of the natural resource water are boosting the demand for profitable, low-cost and highly efficient wastewater treatment systems. Many industrial plants are in sensitive locations, particularly in urban areas, that call for space-saving and emission-free treatment systems.
Due to intensive development work, WABAG has a range of modern reactors available, which can be beneficially employed in accordance with wastewater characteristics. Using our long-term experience from development and full-scale technical practice, we can design and supply optimised, tailor-made concepts for every application.
an-OPUR
This is a classic anaerobic contact process with fully mixed reactor (anaerobic activation process). Circulation is achieved through one or more special mixing devices fitted with guide tubes, which guarantee effective but gentle circulation in the reactor by means of sophisticated hydraulics.
Biomass separation takes place via sedimentation, which is carried out in a special lamella clarifier. The sedimentation unit can either be integrated into the reactor, or installed externally as a separate tank.

This type of reactor is generally employed with wastewater that can be anaerobically treated without major operational problems, but for which the use of granulated sludge is problematic (e.g. sugar- or pulp industry).

Sustainable solutions. For a better life.

The WABAG Group head quartered in Chennai with its global presence in 4 Continents and more than 20 countries has a work-force of more than 2,000. With a history dating back more than ninety years, the group has emerged as a leading pure play water technology player across the globe with focus on emerging markets.
