Dubhe is a leading high-tech enterprise has advanced wastewater treatment systems and environmental protection equipment.

Biological Rope Filler

Braided ribbon fillers are made into curtain fillers based on biological ropes. Braided belt type filler fiber filter material is an environmentally friendly bioactive filler with good water purification efficiency, simulating the form of natural water plants, and is not easy to contain stored sludge. The biological rope made of modified fibers has hydrophilic, oleophilic, cutting effect on bubbles, oxygen storage function, strong adsorption capacity, high biological activity, high mass transfer efficiency, and convenient installation.

Braided belt filler is suitable for the treatment of urban domestic sewage, organic industrial wastewater treatment with various concentrations (chemical industry, wool spinning, printing and dyeing, tanning, paper making, pharmaceutical, food and other industries) and the restoration of micro polluted water bodies such as rivers, lakes, ponds and landscapes in anaerobic, anoxic and aerobic environments.

Characteristics of Rope Shaped Biological Fillers

Unique Structure: The rope type filler adopts a mixed weaving method of elastic and soft materials, and the wiring adopts a serpentine method to form countless circular fibers forming a radial structure, increasing its surface area while being suitable for the growth and reproduction of various microorganisms, so that the concentration of attached microorganisms can reach over 15000mg/l. The circumferential radial structure formed by elastic and soft materials increases the porosity of the filler, enabling good transmission of the solid, liquid, and gas phases. The unique circular structure can effectively avoid excessive peeling of biofilm due to water flow impact.

Wire Rod

The strength of the centerline directly affects the stable operation of the system. With the fixation of the biofilm, the weight of the filler will gradually increase, and it is prone to breakage of wires and central ropes due to the impact of water flow, which affects its service life. The rope type biological filler adopts a high elasticity silk mixed weaving process, and a single mixed weaving wire can withstand a tensile force of 5kg. Due to the central rope fixation method of the rope type biological filler, a total of 12 mixed weaving wires are used in a single section. The measured biological rope filler can withstand a tensile force of 60kg.

Features

● The amount of film hanging can reach 15-20g/L, which is 5-6 times higher than traditional fillers and has a higher organic load.

● Compared with the traditional Activated sludge, the sludge reduction is more than 40%.

● Synchronous nitrification and denitrification have good effects, strong denitrification ability, and a nitrogen removal rate of 80-90%.

● Has lipophilic, hydrophilic, strong adsorption ability, fast film formation, and easy film removal.

● Lightweight, low investment, low operating costs, long service life, convenient installation and maintenance, and easy to use with other equipment.

Function

COMPANY STRENGTH

Rope type fillers can be added to synthetic fiber pairs with appropriate hydrophilicity, biological affinity, charged personality, and substances that help activate microbial metabolism, thereby improving the speed, quantity, and stability of the biofilm, and having strong impact loading capacity.

They can also reduce the capacity of the bioreactor pool. The rope type filler adopts a mixed weaving method of elastic material and shallow nitrogen material, and the new packaging adopts a snake shaped weaving method to form a radial structure of circular fibers, increasing the surface area and suitable for the growth and reproduction of various microorganisms. The concentration of attached microorganisms can reach over 15000 mg/L.

A-9 (4)

Biological rope type fillers are circular radiative structures formed by elastic and soft materials, which can increase the porosity of the filler and enable good transport of solids, liquids, and air. The rope shaped packing ring structure can prevent excessive detachment of biofilm caused by water impact.

Scope of Application

Biological rope fillers have a high porosity, which has a better effect on membrane hanging and removal of high concentration industrial wastewater, replacing traditional elastic fillers and composite fillers. With low porosity and good biological capture capacity, it is mainly used in artificial ecological floating islands of natural water bodies, aquaculture and river treatment, and low concentration sewage with BOD below 50mg/L.

This product is mainly applicable to the purification of urban sewage, domestic sewage, industrial wastewater treatment (wool textile, printing and dyeing, tanning, paper making, pharmaceutical, food and other industries) and polluted water in rivers, lakes and seas.
