This section provides information on project descriptions and viagra canada publications detailing the best available environmental technology in Germany today. The projects published by Cleaner Production Germany are mainly national case studies on environmental protection which has been integrated into the production process. These projects are sponsored by Germany’s national and best way to take cialis regional ministries, Länder-level agencies, or foundations with a governmental mandate. They include, for example, in-depth descriptions of large-scale projects sponsored and find cialis no prescription required verified by Germany’s Environment Ministry (BMU) and Federal Environment Agency (UBA) which demonstrate new ways of avoiding environmental pollution or reducing it significantly. The German Ministry of Education and get cialis online Research also publishes the results of its research into innovative technologies to protect the environment here.

The section is rounded off by publications (final project reports and original brand cialis research papers) for download and get cialis online information regarding statutory regulations and sales cialis specialist events.

The exemplary operation of the sequencing-batch-reactor process developed on a semi-industrial scale has been demonstrated using wastewaters from the paper and viagra sales canada cellulose industry. Positive results obtained from earlier laboratory investigations have been confirmed, and the practical capability of this process for the minimisation of the sewage load in the Elbe has been demonstrated.

Using industrial wastewaters from the Czech paper industry, exemplary laboratory analyses have been conducted in biological wastewater treatment installations with a view to achieving the maximum possible reduction of chemically degradable substances. Periodic Sequencing Batch Reactor (SBR) technology has proved to be particularly suitable for this purpose. Expand…
In a paper factory up to 100% waste paper is used for the production of newsprint. The biological waste water treatment plant is extended with a third stage (flotation) in order to reduce the chemical oxygen demand (COD) in the wash water. A goal is to obtain industrial water quality. For the thermal utilization of the residual substances from fiber production and what better viagra or cialis waste water treatment the waste water treatment unit is supplemented by a sludge treatment and usa pharmacy cialis drainage facility.

In comparison with completely stirred installations, the plug flow process has reduced chemical oxygen demand (COD) by 10 – 15%. The treatment of older sludge has resulted in more extensive COD elimination. For denitrification and viagra tablet biological phosphate elimination, this process has also shown clear advantages over conventional practices. Expand…

Advanced oxidation processes in drinking water treatment for elimination of disinfectants and
buy viagra in us the reduction of potential for reinfection: comparison of oxidation processes
Ozonisation, peroxone, ozone/UV and hydrogen peroxide treatment processes have been applied to three representative waters for the purposes of drinking water treatment. Results obtained for the degradation of trace materials, the formation of disinfection by-products and how strong is 5 mg of cialis the tendency towards reinfection have been compared and documented in a comprehensive tabular compilation. Expand…
In laboratory and semi-industrial tests, the combined oxidation method has proved to be a fundamentally suitable pre-treatment process. Particular strengths have been observed in the removal of impurities from water containing mineral oil hydrocarbons. In consequence, this method is primarily suitable as a standby process for potential surges in the pollution load. Expand…
The effective elimination of bacteria and phosphorous has been achieved using a process combination of precipitation/flocculation/microscreening-microfiltration. Conversely, the use of powdered carbon has not produced any significant removal of adsorbable organic halogen compounds (AOX). Catalytic denitrification has also failed to achieve the desired success. Expand…
The waste water loaded heavily by the waste water from the Textilfaerbereien is biologically cleaned and subsequently treated by means of a combined application of activated carbon adsorption, chemical precipitation/flocculation and filtration (AFF procedure). The visible color could be eliminated, the biologically nondegradable, organic substances including the organic halogen compounds and the phosphorus could be substantially reduced. Expand…

By the parallel operation of a submersed and a fixed bed plant according to the alternating denitrification procedure the transferability of this N-elimination procedure to the fixed bed technology was examined. Also, the suspensa elimination performance as well as the observance of effluent values for filterable materials were compared in both procedures. The procedure of the alternating denitrification could be installed with satisfying results on the fixed bed plant. The ammonium degradation was heavily affected by the suitable procedure, in particular the correct combination of inlet quantities and duration of phase times (detailed information in German).

Using the technology mentioned above the purification efficiency concerning organic waste load and nitrogen does in no way lack behind that of modern large-sized sewage treatment plants. Investment and running cost as well as technological expenditures are comparable with sewage plants without advanced treatment. Expand…
