100% Natural Process

The purification process is fully biological. The bacteria grow on and inside the special BIOROCK® Media. The BIOROCK® units use many of the same water purification processes and principles encountered in nature. Useful bacteria are responsible for degrading the pollutants. These microorganisms are already present in the wastewater and are stimulated by presence of enzymes.

Pre-treatment

Primary settlement is always the first stage in the treatment process. The BIOROCK-5 must be installed after a primary settlement tank. Coarse materials are retained, heavy particles sink to the bottom, while floating items remain at the surface.

Biological

The all-biological treatment process takes place within the BIOROCK® trickling filter. The aerobic bacteria, which proliferate within the media, require oxygen. Their metabolism removes the pollutants. A natural oxygen supply by means of the innovative draft system provides oxygen while reducing the operating costs.

SolarWorld AG relies on Germany as its technology location, thereby ensuring sus- tainable product quality.

The TUV Rheinland Power controlled inspection mark guarantees that the nominal power indicated for solar modules is inspected at regular intervals and thus ensured. The deviation to TUV is maximum 2 percent.

The positive power tolerance guarantees utmost system efficiency. Only modules achieving or exceeding the designated nominal power in performance tests are dis- patched. The power tolerance ranges between -0 Wp and +5 Wp.

With its linear performance warranty covering a period of 25 years, SolarWorld guar- antees a maximum performance degression of 0.7% p.a., a significant added value compared to the two-phase warranties common in the industry. Therefore, the ser- vice certificate offers comprehensive protection for your investment in the long term.
