Sewage Treatment & Recycling
Activated sludge process is one of the old and conventional biological treatment systems for waste water and sewage treatment. Foremost purpose of this treatment is the reduction of biochemical oxygen demands (BOD) , chemical oxygen demand (COD) and other
organics. Activated sludge refers to a mass of microorganisms cultivated in the treatment process to break down organic matter into carbon dioxide, water, and other inorganic compounds.
There are many variants of activated sludge processes, including variations in the aeration method and the way the sludge is returned to the process. The activated sludge process works in a complex ecosystem of competing organisms. Deknomet’s comprehensive portfolio is designed to address typical challenges in sewage treatment such as variable inflow, seasonal peaks and high organic load, space constraints and sludge management. Our technologies are the result of intensive multidisciplinary research and development which integrates fixed film and suspended growth process considering highly effective surface area for biomass growth and optimal oxygen transfer efficiencies.
Advanced Moving Bed Biofilm Reactor(AMBBR)
Advanced Moving Bed Bio film Reactor (AMBBR) a bio film based biological process designed to increase the capacity and efficiency of BOD and nutrient removal in waste water & sewage treatment plants. AMBBR is effective, robust, cost efficient, stable
& space saving technology available today. Any MBBR systems will use plastic bio film media to create active surface area for bacterial growth and the capacity and size of the plant largely depend on the
surface area requirement.
Our AMBBR system is provided with a special bio film media with very high active surface area per cubic meter volume and it is the single media available today with such high area. The media has a self cleaning effect and hence clogging will not happen and its active surface areas are available at all times. The AMBBR stay clean with stable capacity without the need of cleaning or flushing. The design ensures that bio films formed are new and thin with short transport distance so that less time is required for bacterial growth. AMBBR system is an easy option for treatment capacity enhancement and replacement of existing systems without much modification and destruction in the existing systems. AMBBR can be replaced and due to its large surface area, the current treatment capacity can be increased. The operational udgradation or capacity increase can be managed by replacing the existing system with AMBBR.
Sequential Batch Reactor(SBR)
The sequential batch reactor (SBR) is batch process that consists of separate process steps for filling, reaction, sedimentation and discharge in one cycle. These steps run in defined timely manner and depend on the waste water to be treated. The complete division of the treatment system ensures to overcome all difficulties in the continuous process and the SBR systems can not only remove the BOD and suspended solids but it can be very effective for the removal of Ammoniacal nitrogen (NH4- N) and phosphorous (P). The SBR process ensures excellent settling characteristics of bio sludge, simplicity in operation, less foot print and very less maintenance and operation cost. In our association with technological experts, Deknomet provide a complete and comprehensive SBR solution for the industrial applications.
Unaerobic Sludge Blanket Reactor (UASBR)
Deknomet is specialized in the anaerobic treatment of wastewater from food, beverages, diary, confectionery and pharmaceutical industries. One of the main advantages of this kind of reactor is the low sludge production and the production of biogas and
- Energy consumption is very low due to non requirement of oxygen supply & mixing.
- Most of the organic material in the waste water is converted into biogas, which can be combusted.
- Most of the organic material is converted into biogas, not in sludge and hence sludge production is very low
- The anaerobic sludge is stabilized and can be easily dewatered by gravity. Sludge handling costs are minimal
- The anaerobic sludge can be easily stored and conserved, which simplifies second start-ups after production stops or periods with reduced organic loading rates
- Investment costs are low, because high reactor loading rates and short retention times are applied.
