DCD Mini Modular Wasterwaterplant

BouwCoach Engineering BV

DCD Mini Modular WasterwaterplantPurifying SystemFor purifying the wastewater, the DCD-Bever works with the activated sludge process which is used worldwide (patented technology Afmitech Friesland bv). In this process the pollution is degraded biologically by micro organisms floating in the water. These micro organisms form a floc, which is the so-called activated sludge. Because this activated sludge is heavier than the water in the tank, it will sink down in the settling compartment from where it can be separated from the water flow. The installation is made vertically with a surface aerator which creates a vertical circulation by intermittent aeration. This vertical circulation makes denitrification possible. The system itself signalizes the amount of wastewater coming in and automatically adjusts the oxygen input while the purification process continues; this means that the DCD-Bever has a continuous purification process with a discontinuous control. In this way, the wastewater treatment system can perform properly with changing seasonable loads. The excess growth of sludge is automatically thickened and periodically drained to the excess sludge sump. In this way the system keeps the concentration of excess sludge in the aeration compartment stable and prevents the wastewater treatment tank from becoming overgrown with sludge.


Test Results:Our Bever wastewater treatment system (patented technology Afmitech Friesland bv) is extensively tested for 26 weeks in 2002 by the Van Hall Larenstein Institute, Leeuwarden. During the attestation, only flux-proportional collect samples of the effluent were taken and analyzed by an accredited research laboratory.

These assumptions are based on conservative Key-Figures, nevertheless always discussable.But the results of the comparisation of average investment costs for DCD-Bever systems and traditional shows a factor 3 in lower costs for decentral systems!

To be able to compare the investment costs with a traditional (50.000-100.000ie) wastewater treatment plant, some assumptions are made: 1) investment costs for traditional plant are € 200,- per i.e. 2) investment in meter sewage pipe is € 100,- 3) the distance from “lowest” village to a traditional wwtp is 10km.

Cost Comparisation

For 25 communities in the Arad Area businesscases are established.These communities vary from 700 inhabitants spreaded over 3 towns to 3000 inhabitants in 10 villages . The calculated average cost of ownership for complete DCD-Bever community systems (excluded village-canalisation) go down to € 22,- per inhabitant per year (with EU funding included).When the investment costs are compared, the absence of inter-village sewers and main sewer to a traditional plant, cause a significant cost-difference in favour of decentralized units.


Modular ApproachThe Bever-DCD system is a modular system of decentral wastewater-treatment for communities from 50i.e., 100i.e. and 175i.e in steps up to 2500/5000 i.e.This modularity guarantees flexibility in phasing, providing any needed growth of connected population and/or availability of canalization.Also innovation in purification technologies develops fast. This modular approach guarantees, (in combination with 15 or 25 years administrative life-time) the flexibility of replacing systems or system-parts at any time.Waste and wastewater become more and more a source of energy and raw materials (as for example phosphorus). Modular units can be added for extraction of specific substances and exploiting the energy sources in near future.At last but not least, the awareness of health-threatening pollutions, as for example medicine and metals, will demand purification on these substances in near future. Our modular systems can be expanded at any time with the newest technology.
