There are many types of fillers for sewage treatment, which are mainly used to provide a surface for microbial attachment, promote water flow and improve treatment efficiency. The following are some common types of fillers for sewage treatment:
1.MBBR filter media:
Mbbr filter media is HDPE material which is a porous suspended filler specifically designed for use in biofilm reactors. It is typically a plastic or ceramic material with a large specific surface area.It is widely used in municipal sewage treatment, industrial wastewater treatment, etc.
2.Honeycomb inclined tube settler:
Honeycomb inclined tube settler is hexagonal honeycomb tube filling material mainly used for various sedimentation and sand removal processes, with advantages such as high treatment efficiency and small footprint. Widely used for general industrial and domestic water sedimentation, sewage sedimentation, oil separation, and tail tension concentration treatment.
Material:PP,PVC,RPP,SS304,SS316L.
3.Combined packing:
Combined packing is composed of plastic rings and fiber bundles, with high heat dissipation performance, low resistance and good water distribution. It is widely used in sewage and wastewater treatment projects, supporting and contacting oxidation towers, oxidation tanks, oxidation tanks and other equipment.
4.Multi-side hollow sphere:
Multi-side hollow sphere is made of PP material and is composed of two hemispheres to form a spherical shape. Each hemisphere has 8-12 semi fan-shaped blades according to design requirements, and the fan-shaped blades of the two hemispheres are staggered from each other. It has the characteristics of large specific surface area and high porosity and is widely used in environmental protection equipment such as chlorine gas, oxygen removal, carbon dioxide removal absorption towers, exhaust gas purification towers, acid mist purification towers, etc. In water treatment, it can also effectively remove gases such as oxygen, chlorine gas, and carbon dioxide from purification towers.
5.Spiral corded bio rope filler:
Spiral corded bio rope filler is a rope like structure composed of PP and fibers, forming a circular group of small filaments centered on a fine rope and radiating outwards in a three-dimensional state. It has certain rigidity and flexibility, long service life, good water and gas distribution performance, low energy consumption, easy membrane detachment and renewal, and no blockage. It is widely used in fields such as domestic sewage treatment, river purification, and aquaculture.
