Biogas plant DorstenThe structural - and civil engineering works of the first construction phase of the biogas plant in Dorsten were nearly completed by the end of 2011.
The technical equipment is assembled at the moment. Depending on the local weather conditions the surface- and road work will be carried out in the first quarter of 2012. In parallel to construction of the first construction phase Dr.-Ing. B. Diering GmbH was commissioned for planning services of the second construction phase by EnD-I Bioenergy Dorsten GmbH & Co. KG. Two concentrate tanks with 3,000 m³ useful volume each, another bunker silo with two chambers as well as a digestate refining with solid-liquid separation, ultra-filtration and reverse osmosis are planned for the liquid refined products in this extension measure.
Construction works for the second construction phase have already begun.

Biogas plant Dorsten
The constructive works at the biogas plant in Dorsten for the construction of 8 fermenters with a volume of approx. 3,100 m³ each are progressing well. The complete civil
engineering works of the fermenters, pipeline bridges and stair tower foundations will be finished in calendar week 8. Four fermenter tanks were installed within short time by the plant manufacturer due to increased employment of staff and mild outdoor temperatures. Only the service platforms have to be installed. Two further tanks are currently being
assembled. The completion of all assembly works is scheduled for the end of June 2011.
Currently Dr.-Ing. B. Diering GmbH provides the award procedures for the civil engineering works tendered for the remaining structures of the biogas plant in Dorsten. The
commissioning is carried out by the client in the first quarter of 2011, so that construction works can start immediately. Our engineering company was commissioned by EnD-I
Bioenergie Dorsten GmbH & Co. KG to provide the detailed design, the award procedure as well as quality assurance for this reference project.

Biogas plant Boppard
The official authorization according to Federal Immission Control Act for the biogas plant in Boppard was granted early February 2011.
The biogas plant in Boppard is planned for utilization of renewable raw materials for an electrical power of 2.5 MWel. The produced biogas is treated and fed as biomethane gas into the public gas distribution system.
Our company provided the following services in the last 7 months:
- Basic evaluation
- Preliminary design
- Basic design
- Approval planning
- Most of the detailed design
- Preparation of awarding (preparation of tender documents)
The tender documents were sent to the companies right after authorization. The start of construction is scheduled for mid-May 2011.

BGA Dorsten
The first earthwork measures started in the middle of September 2010 after several years of
design and approval procedures. Two of eight digesters are to be finished before Christmas at the biogas plant Dorsten. The main construction works will start after winter season 2010/2011 and shall be finished at the beginning of 2012. Our company was commissioned with the quality man-agement and preparation of the tender documents for this reference project of the company EnD-I AG.

Diering goes Egypt!
Our company currently prepares the basic and detail design for a two-stage aeration plant for a mixed municipal/industrial wastewater treatment plant (WWTP) in the northern part of Cairo, Egypt. The WWTP designed 10 years ago became too small due to a considerable increase of industrial settlements in Mubarak Industrial City. Thus an adapted process design according to AB-procedure was chosen. The new WWTP is to be extended for 2,750,000 PE.

The water circuit at Cargill plant in Salzgitter is closed!
The authorization for the project "Production-integrated environmental protection at Cargill plant Salzgitter" was given and the construction and installation works have started. The commissioning of the plant, including the process steps biological treatment, ultra filtration and reverse osmosis, is scheduled for December 2010.

Biogas plant Saelhuysen
The biogas plant Saelhuysen in Rheurdt was designed for a connected load of approx. 1.2 MW. The preliminary design, the approval planning, the preparation of tender documents, the technical plant layout as well as the assistance and evaluation in the tender process already have been finished.
The project control and the project coordination are also provided by Dr. -Ing. B. Diering GmbH. In the current construction phase the digesters and containers are assembled.

WWTP RESITA
The WWTP RESITA in Romania (~ 125,000 PE), designed for nutrient elimination and anaerobic sludge stabilisation, started operation early in August after two years of design and construction phase.
Dr.-Ing. B. Diering GmbH provided the following engineering services:
Approval planning, detail design, preparation of operation manual, training of the operational staff, preparation and assistance in the commissioning process, as-built documentation.

New documentation system
Web-Info System Eco (Wise) is almost finished.
A web-based information platform was developed and tested in daily operations during the years of cooperation with the operator of the WWTP Krefeld. Wise can be applied universally. It alleviates the provision and administration of all documents, which are necessary for the operation of technical plants. Besides economical advantages, Wise especially provides the user with legal security.

System integration of new planning software
One goal in our quality policy is the permanent improvement of our services in regards to customer oriented planning. Therefore we introduced an innovative planning software by Aucotec AG in March 2010. This software package Engineering Base Instrumentation Pro guarantees a significant improvement in our planning services and ensures a higher quality and shorter project duration in basic engineering and in the detail engineering.
