System Filter / integrated filter HSF system filter patent number: ZL 2013 2 0689592.3 HSF system filters Product Description Automatic system filter is a combination of Germany advanced technology, independent research and development, a Chinese-made compact, low power filter Use 60μm filter bowl to remove the waste and sewage fines and biofilm Degradation of organic nutrients. HSF system filter characteristics 1. combine drum filter and bio filter 2. a national patent, patent number: ZL 2013 2 0689592.3 3. Very easy to install and low maintenance 4. 5. 6. Automatic cleaning environmental quality 7. All equipment material long life 8.1 years warranty automatic system filters included: a controller for refill the pond solenoid valve connectors, cleaning pump, pump, circulation pump for cover and UV mercury Homogeneous light 42w sensor. Automatic system filters can operate in gravity mode or pump mode. When installed, simply connect the inlet, outlet and sewers. Just a plug can be connected to power. All units are pre-installed in use. Water intake by input HSF, flows into a collection box, from here into the filter inside the drum, the drum is covered with a 60μm filter microfilter. Water filter to leave only after filtration drum, all the particles are larger than the filter will remain in the filter drum. Waste particles will slowly clog the filter, making it difficult water through the filter, causing the water level slowly drop water collection box. Once the water level dropped to the lowest level of a good set, the sensor gives the signal, the digital control unit will start the flushing process. During rinsing, the filter drum rotating motor drive gear, a plurality of high-pressure water jet spray nozzles to the outside of the filter. Clogged filter waste is flushed into the waste tray, and then leave the filter through the wastewater discharge outlet. After the drum filter through the water treated by the Unicom pipe into the air swirl box, suspended in the air swirl tank filler surface adhesion of biofilm organisms, fish ponds in the biofilm can degrade nutrients, break it down into harmless nitrogen emissions into the air, at the bottom of the air box is installed EPDM swirl diffusers accelerate the decomposition process and produce sufficient oxygen, clean water flows out through the outlet.
