COMPACT MBR

COMPACT is a state-of-art pre-engineered sewage treatment system utilizing PACT's biological treatment expertise with TORAY's submerged membrane technology, it contains the process elements of secondary, tertiary and advanced wastewater treatment in a single containerized package. The membrance separation process eliminates the conventional sedimentation tank and allows high volumetric loading resulting a much smaller footprint. COMPACT can produce high quality effluent with high BOD5 removal (about 98%), complete nitrification and partial denitrification. It also achieves virtually complete TSS removal. Treated effluents have low turbidity values (<0.3 NTU) and SDI values (<3) which can be re-used for landscaping, flushing or feed to NANO or RO for higher purity water.

COMPACT uses TORAY flat sheet membranes, immersed in the process tank and in direct contact with the mixed liquor. Air ejected from a manifold and the bottom of the membrane assembly help keep the membrance surfaces clean as well as to supply oxygen for biological growth.

COMPACT is equipped with a high level of automation, ensuring the plant's simple operation and low maintenance cost.

COMPACT membrane modules are submerged directly within the bioreactor. It is tyically operated in a considerably different range of parameters for the mean cell residence time and substrate utilization rate than the conventional activated sludge processes. Due to this difference, COMPACT offers several benefits over the conventional activated sludge process. These benefits include:

much smaller space requirement;

better solids removal(elimination of bulking);

disinfection;

increased volumetric loading;

de-coupling of hydraulic and biomass retention time;

production of less sludge due to high sludge age;

high SRT which allows the development of slow-growing microorganisms such as nitrifying bacteria; and

retention of high molecular weight organic compounds that can enhance the biodegradation process.


The modular concept allows for phased construction of wastewater treatment plants and makes it adaptable to a wide range of sizes and flow rates.
COMPACT can be delivered as a containerized unit. This solution has some advantages such as:

factory installed and tested
no construction works on-site
short delivery period
easy to relocate
