Product introductionAeration biological filter special anti-clogging long handle filter head, composed of filter rod, water filter cap, strong casing, filter rod casing pre-embedded in the coagulant filter plate, and with inner wire thread, conventional filter plate thickness = 100mm. The long-handle filter head is made of ABS engineering plastic injection molding, with high compressive strength, no crushing when stepped on, firm connection, and can ensure that the filter head does not fall off after installation. The long-handle filter head is equipped with a two-way anti-blocking lower end with a filter hood to effectively prevent debris from entering the filter rod, and the impurities attached to the lower filter cap can be removed by falling water level, and if necessary, the long-handle filter head and the filter plate can be replaced without stagnant water area, and no sludge accumulation is blocked.

Combined porous ring filler, 40 square holes are placed around the plastic ring, and eight bundles of aldehyde filaments are distributed around it. Each bundle of filaments is connected with 4 square holes, so that the firmness of the aldehyde filament on the plastic ring is self-evident. In the case of strong aeration turbulent water airflow, it is ideal to choose a filler. Porous ring packing and combined bicyclic packing are largely the same in the wastewater treatment process.

Composite fillers are widely used in printing and dyeing, silk and wool spinning, food, pharmaceutical, petrochemical, papermaking, etc. due to their advantages such as large specific surface area, high oxygen utilization rate, variable voids, non clogging, and wide applicability· In the treatment of wastewater containing cyanide, it is highly welcomed by users. The composite filler is supported by a plastic ring as the skeleton, loaded with vinylon silk, which is fastened to the plastic ring and evenly distributed in the sewage material. It is easy to form and replace films, and has good adaptability to concentrated sewage.

Elastic fillers have fast film formation, easy film removal, and good biofilm growth and renewal. It is resistant to high load impact, has high CODcr removal rate, good treatment efficiency, and good oxygenation performance. It can perform multi-level collision on bubbles and intensive cutting, greatly improving the transfer and utilization rate of oxygen, reducing power consumption, and has a novel structure. The effective specific surface area is large, non agglomerating, non clogging, and has a long service life. It can also be reused, and the management of productive operation is simple. Strong adaptability, with good treatment effects for low concentration domestic wastewater, medium concentration printing and dyeing wastewater, papermaking wastewater, oily wastewater, high concentration food industry wastewater, chemical wastewater, etc. Can be widely used in aerobic, facultative, and anaerobic treatment processes
