Activated Sludge Process Utilizing Membrane Technology

By utilizing the latest Membrane technology in combination with activated sludge treatment, not only can a significant amount of space be saved, but also a clarification process that is free of bacteria and particles can be achieved, even in the presence of variable elements.

Unlike many other submerged filter systems, our AQQA membrane is a “true” ultra-filtration membrane, providing a much higher retention rate compared to a micro-filtration membrane. This allows for the secure retention of bacteria, and even viruses, with up to 99.9999% effectiveness.

Furthermore, our Membrane filters exceed European Regulations for Bathing Water Quality “2006/7/EG” without the need for additional tertiary treatment.

Operating Principle

The offered throughput system with cascade technique is designed in accordance with the activated sludge (extended aeration) principle with MBR-technology.

The raw sewage water flows in a lifting station from where it is pumped to the automatic fine screen with 1mm slot. The screened materials are removed and automatically transported in a solid waste container without the plant operator making direct contact with the waste.

From the aeration tanks, the activated sludge mixture is extracted over the AQQA filter membranes (plate membrane system) (<0.1 microns) with a permeate pump.

Excess sludge produced during the treatment process is removed from the MBR tanks by a submersible pump to an excess sludge holding tank for evacuation. With a sludge press or drying system, the sludge can be dried.

Our containerized solutions offer different package options.

Our designs are meticulously calculated and developed in compliance with the ATV and conform to all relevant standards and regulations from the European Union pertaining to wastewater treatment.

All mechanical equipment components, including electrical measuring and control devices, are installed within a CSC approved ISO Norm-container. To ensure that raw wastewater in the tank does not come in direct contact with the steel container wall, the internal walls of the ISO Norm-container are lined with a High Density Polyethylene lining. This effectively prevents corrosion and significantly extends the container’s lifespan.

The containers are available in 20ft, 40ft or 40ft High-Cube ISO Norm Containers, with hydraulic load capacities ranging from 20 – 160m3/d (200PE – 450PE), 45 – 350m3/d (450PE – 100PE), and 55 – 440m3/d (550PE – 1250PE), respectively.

Furthermore, we offer the option of modularity, which enables us to expand the capacity of our wastewater treatment systems by assembling several container options together, according to the end-user’s specific requirements.

HDPE Tank

In situations where an ISO Norm Container is not suitable, we offer the option of installing the mechanical and electrical equipment in high density polyethylene (HDPE) tanks.

The treatment process remains the same, with only the holding tanks being different. Nevertheless, the modularity advantage is still present in this configuration, enabling us to achieve nearly the same capacities.

Concrete Tank Installations

With our layout design, we can provide guidance to the construction team of the end-user regarding the required dimensions for the installation of the MBR system in a reinforced concrete tank.

Our system has the capability to treat a daily hydraulic load capacity ranging from 20m3 to 20,000m3.
