Modular BioDisc Sewage Treatment Plant

High Performance Modular Sewage Treatment Solution

Kingspan Modular BioDisc containerised sewage treatment plant is available from 300 population equivalent to 2500 population equivalent as an above or below ground option for a flexible engineered solution.

Delivering an improved biological process and overall treatment efficiency, the unique flow management system can be adapted to manage seasonal fluctuations.  

Modular System Allows Room To Grow

The Kingspan modular BioDisc system is designed for applications with higher populations. The Rotating Biological Contractor (RBC) system comprises of a complete modular system containing both the RBC units along with primary and final settlement tanks. The number of RBC units and tanks can be increased in numbers or size to make a flexible system for an expanding or phased population growth. Each of the units can be linked to create a complete sewage treatment system.

How the treatment process works.

Flow Management Process

Sewage Treatment Plant Flow Management Process
The unique BioDisc® flow management process allows for complete flexibility of forward feed rate. Rotating buckets transfer untreated water through each of the BioZones, allowing for total forward feed control. These are independently driven and allow the buckets to run at a different speed to the rotor.

Sectional Media Modules

Sewage Treatment Plant Sectional Media Modules
The Biozone media within the BioDisc® Modular system is built up in ‘wedge’ sections to make a two-metre diameter rotor assembly. A complete wedge can be removed from the rotor for maintenance or inspection without compromising the overall rotor structure. This ensures the rotor assembly can stay in place, without the need for removal.

Rotor Support Bearings

Sewage Treatment Plant Rotor Support Bearings
The rotor assembly within BioDisc® is supported by a pillow block bearing at each end of the rotor shaft. These are equipped with self-lubricating grease cartridges to provide continual lubrication. Both bearings can be accessed by removing the individual covers for maintenance. It is not necessary to remove the larger main covers, allowing for easier maintenance.

Strapping Points

Sewage Treatment Plant Strapping Points
The treatment plant can be lifted from the side by forklift truck. Forklift tubes are built into the steel construction frame. The unit can also be lifted at either end with the aid of extension forks. Alternatively, the unit can be lifted with slings. Four lifting brackets are attached to the frame and lifting shackles are provided with each unit.
