The document summarizes the European Commission's Eco-Design regulation for electricity transformers. It established efficiency tiers in 2015 and 2021 to reduce transformer losses and greenhouse gas emissions. By optimizing transformer designs, the regulation is expected to save 16.2 TWh of energy per year by 2025, reducing CO2 emissions by 3.7 million tons. The regulation standardized transformer types and significantly reduced the allowed losses for new transformers to meet the tiers. This led manufacturers to offer fewer, more efficient transformer models.
This document provides information about Aqua Seen, a company that specializes in water treatment. It has over 20 years of experience and has completed almost 1500 projects in Poland and abroad. The company offers design, equipment, and turnkey solutions for drinking water treatment, sewage management, and renewable energy. It has divisions for potable water, equipment, service, and research and development. The document then describes several large water treatment plant modernization and construction projects the company has completed.
The document summarizes the results of a project that assessed the influence of smart grid technologies like decentralized storage and demand response on long-term energy system planning for a region. Surveys were conducted in Switzerland to evaluate acceptance of demand response programs and using electric vehicles as temporary energy storage. Results showed around 80% acceptance of demand response scenarios and 84% acceptance of electric vehicle storage scenarios, with little sensitivity to implementation details. Energy system modeling was also used to assess different technology and policy scenarios over 10-50 year time horizons.

This document discusses two innovative processes for upgrading biogas - AwR and BABIU. AwR uses an aqueous alkaline solution to absorb CO2 from biogas, producing an upgraded biomethane and an alkaline process residue (APC). BABIU uses alkaline fly ash or bottom ash (BA) from waste-to-energy plants to absorb CO2 through carbonation. The document analyzes the operating conditions, costs, and upgrading efficiencies of both processes and concludes that while AwR has higher CO2 uptake its costs are also higher, whereas BABIU has lower costs but requires more solid residue. Future work is suggested to further improve the processes.

Paul de Lange MSc: 0031-654223534
3. DCD Mini Modular Wasterwaterplant
Purifying System
For 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.

6. 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.
BouwCoach Engineering BV
7. Modular Approach
The 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.
