Advantages of IRDS

•Compared with the external inlet drum grating, the scum is removed from the end of the drum and does not enter the subsequent stages.

•Compared with the external inlet drum grating, it is suitable for treating sewage with large amount of scum and complex type of scum, such as poultry, slaughtering, breeding and other wastewater.

•Compared with the external inlet drum grating, slow speed, high stability, basically no wearing parts.

IRDS Rotary Drum Grille – Fibre Filtration Processes

Rotary Drum Screen Design Rotary Drum Screen Wholesale - DUBHE 13

COMPANY STRENGTH

When the raw water containing fibre impact drum grille drum surface, much larger than the length of the mesh diameter of the fibre cannot pass through the perforated mesh surface, is retained in the drum body wall, with the rotation of the drum, through the end of the slag outlet. Close to the length of the mesh diameter fibres are mostly retained in the inner wall of the drum.

Rotary Drum Screen Design Rotary Drum Screen Wholesale - DUBHE 14

COMPANY STRENGTH

There is a part of the probability of fibre perpendicular to the mesh, through the perforated mesh plate, the probability is not large, but reduce the fibre removal rate. There exists a part of the fibres smaller than the length of the mesh diameter, blocked by large fibres, are also retained in the inner wall of the drum, improving the fibre removal rate.

D-1

In short, the choice of mesh diameter should be based on the length of the majority of fibres in the raw water accounted for a percentage of the decision, otherwise affect the fibre removal rate.

Fibre Movement Processes

Being mesh plate retained fibres in the drum enrichment, enrichment fibre blocked part of the mesh, reducing the grille water capacity, in the drum grille selection of the early stage, will be in advance to take into account the clogging factor.

When the enriched fibre reaches a certain amount, with the rotation of the drum and the internal slag screw guidance, open the "snowball" mode, the fibre attached to the inner wall of the drum rolled into a "ball", with self-cleaning ability.

Part of the fibres stuck in the mesh or the gap, through the backwash nozzle cleaning, back into the drum, joining the "snowball" mode.

2/3 of the length of the drum is designed to be used for passing water and 1/3 for draining to ensure that the moisture content of the slag at the end is within a reasonable range.
