Rotor Disk
| Sewage treatment process is intended to remove/reduce undesired components that present in water such as high organic content, suspended solid, pathogenic microorganism, toxic material, dissolved solid and non biodegradable material. Those components will decrease the water quality and can pollute environment, especially the water resource quality. Therefore to prevent the pollution, the sewage has to be treated before disposal. In general, some process stages occurred in the sewage treatment ROTORDISKTM system are : Primary Clarifier, ROTORDISKTM Module, Final Clarifier, Chlorination System, Ultimate Disposal, as shown on process flow diagram.
The patented ROTORDISKTM wastewater treatment plant integrates for separate operation into one system:
Primary settling tank for suspended solids and grit removal
The ROTORZONE located over the primary tank, consist of a through and shaft on which a multiple number of disk are mounted. The disks are 40% immersed in the wastewater being treated. Each disk is made of a high density polyethylene mesh which provides a greater effective surface area than flat or corrugated disks. SLOW ROTATION of these disks alternately exposes the attached micro-organism to the wastewater and air allowing for pollutant absorption and oxygen uptake. The naturally accuring micro-organism, or biomass, feed on the organics waste and convert it into CO2 and H2O. Fixed baffles are used to provide distinct stages in the ROTORZONE and a SERPENTINE FLOW PATTERN is used to achieve the maximum retention time.
Advantages: Cost Effective, Energy Efficient, Stable Operation, efficient Treatment, Small Footprint, Compact and Modular, Easy Installation.
