(Trademark No. 40-1444901)
Structure
With no blockage structure, air is supplied to the lower part and discharged through the upper part.
Air and surrounding water rise together due to the air lift.
Microbubbles are generated by swirling across the air bowl inside the aeration device, and convection circulation is formed with sewage.
Features
DO is increased due to excellent ventilation and low ventilation resistance (Keeping a minimum DO concentration of 2.0 mg/L)
High ventilation and low installation quantity compared to models provided by other institutions make maintenance easy (60%).
Low power cost thanks to excellent oxygen transfer efficiency (saving 15-20%)
Maintains the best performance and excellent durability without clogging, deformation or corrosion
Simple construction and low construction cost
No replacement cost because the service life is 15 years (5 years for other companies)
Adopts swirl flow side aeration
A-Type (2 pcs/set) and B-Type (4 pcs/set) are installed.

This disk-type fibrous filter is used as a tertiary treatment facility for public sewage facilities and wastewater facilities.
Each media consists of six frames with high-strength fiber membrane filters.
The treated water flows out through the central discharge pipe, and the entire process can be operated automatically or manually.
Fiber filter (K-DISK) structure
Fiber filter (K-DISK) principle
The influent goes through the fiber filter and enters the disk, and the treated water is discharged through the central discharge pipe by natural flow.
The sensor detects the rise in the water level in the filter paper due to clogging of the filter cloth.
As the disk rotates at 1 rpm, the backwash suction plate sucks and removes the solids accumulated on the surface of the filter cloth utilizing the suction force of the pump.
Filtration is ongoing on the surface of the fabric filter even during the backwashing process.
The solid material that has settled on the floor is recirculated to the front stage of the treatment plant by a pump according to the set cycle.
Features
Operates with a static head by natural flow; automatic backwashing is activated according to the difference in the water level.
Even during backwashing, the filtration process proceeds continuously, and there is no need for a separate spare machine; continuous, 24/7 operation is enabled.
The amount of backwash is very small, at about 3-8% of the inflow water.
It maintains high processing efficiency even under a very high solid or hydraulic load compared to the efficiency offered by the existing filter paper.
It has excellent responsiveness to load fluctuations. Through periodic discharge of the sediment solids, it reduces the load on the filter during shock loads, enabling stable treatment.
Compared to the existing filtration facilities, it is possible to reduce the costs of constructing the site foundation by saving 75-85% of the site area.
The structure is simple and automatic operation is possible.
Because the filter cloth receives pressure only during the backwashing process, the wear rate is low and the lifespan is long, so maintenance costs can be reduced.
