Unlike traditional fillers that suffer from easy clogging, poor film-hanging performance, or short service life, our Elastic Stereo-Filler features a unique three-dimensional radial structure—elastic filaments with tiny burrs are evenly fixed on a high-strength central rope, forming a fully expanded, porous spatial structure. This innovative design maximizes the specific surface area, promotes full contact between gas, water, and biofilm, and enables automatic biofilm renewal, effectively solving industry pain points such as biofilm agglomeration, uneven water distribution, and low oxygen utilization rate. It is widely applied in municipal sewage, industrial wastewater (textile, food, pharmaceutical, chemical), and aquaculture water treatment, helping enterprises optimize treatment efficiency, reduce energy consumption, and lower operational costs.

Product Feature
Core Working Principle
The Elastic Stereo-Filler operates as a high-performance biological carrier, relying on its unique structural design and material properties to facilitate efficient microbial growth and pollutant degradation, integrating seamlessly with various biochemical treatment processes:
1.Microbial Attachment & Film-Hanging Stage: The filler’s elastic filaments, with a rough surface and large specific surface area (150–350 m²/m³), provide ample attachment points for microorganisms (bacteria, protozoa, fungi). The hydrophilic additives in the material accelerate microbial colonization, enabling rapid film formation—usually achieving stable biofilm coverage within 7–10 days, which is 30% faster than traditional fillers. The biofilm attached to the filaments forms a gradient microenvironment (aerobic outer layer, anoxic inner layer), facilitating simultaneous nitrification and denitrification.
2.Pollutant Degradation & Mass Transfer Stage: As wastewater and aeration gas flow through the filler, the three-dimensional radial elastic filaments swing with the water flow, effectively cutting bubbles into smaller particles—improving oxygen transfer rate and utilization rate by 20–30% compared with conventional fillers. The fully expanded structure ensures uniform distribution of gas and water, allowing full contact between pollutants in the wastewater and the active biofilm. Microorganisms on the biofilm decompose organic matter, ammonia nitrogen, and phosphorus into harmless substances (CO₂, H₂O, nitrogen gas), achieving efficient wastewater purification.
3.Biofilm Renewal & Long-Term Stability: The elastic nature of the filaments causes mutual friction and collision during water flow and aeration, which automatically peels off aged, inactive biofilm—ensuring the biofilm remains active and efficient. The large porosity (≥98%) and variable pore size prevent clogging, even in wastewater with high suspended solids (SS) content. The corrosion-resistant material ensures stable performance in harsh water environments (acidic, alkaline, high-salt), maintaining long-term operational reliability.
Key Product Advantages
1.Superior Film-Hanging Performance: Rough-surfaced elastic filaments with hydrophilic additives enable rapid microbial colonization, with stable biofilm formation in 7–10 days. The large specific surface area (150–350 m²/m³) and 360° radial distribution provide ample attachment space for microorganisms, significantly increasing microbial biomass and pollutant degradation efficiency.
2.Anti-Clogging & Self-Renewing: Variable pore size (≥98% porosity) and elastic structure allow the filler to swing with water flow, avoiding agglomeration and clogging—solving the common problem of traditional rigid fillers. Mutual friction between filaments realizes automatic renewal of biofilm, maintaining high microbial activity and reducing manual cleaning frequency.
3.High Oxygen Utilization & Energy Saving: The radial filament structure effectively cuts bubbles, refining aeration and increasing oxygen transfer rate by 20–30%. This reduces aeration energy consumption by 15–25% while enhancing the efficiency of aerobic biochemical reactions, lowering overall operational costs.
4.Durable & Corrosion-Resistant: Made of high-quality polyolefin (PP) or polyamide materials, mixed with anti-aging, anti-oxidation, and hydrophilic additives, the filler can withstand long-term operation in acidic, alkaline, and high-salt wastewater (pH 2–12). It has excellent wear resistance and thermal stability (continuous service temperature: -15℃ to 100℃), with a service life of 3–6 years depending on working conditions.
5.Cost-Effective & Easy Installation: Compared with semi-soft and rigid fillers, it has a lower cost while offering better performance; compared with soft fillers, it has a longer service life and no agglomeration issue. Modular design with standard specifications (diameter 150–200mm) allows flexible combination, and installation is simple—fixed on upper and lower frames with binding ropes, reducing labor and installation costs.
6.Strong Adaptability & Versatility: Suitable for various water treatment processes, including biological contact oxidation tanks, hydrolysis acidification tanks, anaerobic reactors, and aquaculture water purification systems. It can adapt to fluctuations in wastewater quality (COD 200–5000 mg/L) and flow, with strong impact load resistance, making it ideal for municipal and industrial wastewater treatment.
7.Environmentally Friendly & Non-Toxic: The material is non-toxic, odorless, and meets international environmental standards, causing no secondary pollution to water bodies. It is recyclable and conforms to global green water treatment and circular economy trends.
8.Global Compliance & Customization: Fully complies with ISO 14001, EU, and US EPA water treatment standards. We provide customized solutions (material, size, density) according to the specific water quality, treatment process, and regional requirements of customers—including high-density models for high-concentration organic wastewater hydrolysis acidification stages.
Typical Applications
Our Elastic Stereo-Filler is widely used in municipal, industrial, and aquaculture water treatment scenarios, serving as a core biological carrier for efficient pollutant degradation:
1.Municipal Sewage Treatment: Biological contact oxidation tanks, hydrolysis acidification tanks, and rural decentralized sewage treatment systems—removing organic matter, ammonia nitrogen, and phosphorus to meet discharge standards.
2.Industrial Wastewater Treatment: Textile, printing and dyeing, food processing, pharmaceutical, and chemical wastewater treatment—improving wastewater biodegradability in hydrolysis acidification stages and enhancing degradation efficiency of refractory organic pollutants.
3.Aquaculture Water Purification: Recirculating aquaculture systems—removing ammonia nitrogen, nitrite, and organic residues to improve water quality and reduce water exchange frequency.
4.Industrial Water Treatment: Pretreatment of industrial process water, circulating water purification, and wastewater reuse systems—removing organic impurities and ensuring water quality stability.
5.Special Water Treatment: Landfill leachate pretreatment, hospital wastewater treatment, and breeding wastewater treatment—adapting to high-concentration, high-toxicity wastewater conditions with strong impact load resistance.
