sewage treatment systems.


Domestic sewage.

Most conventional wastewater.

Sewage is the most conventional wastewater. It is relatively the easiest to handle, unless there are exceptional contaminants such as substantial oil and grease, chemical content etc, or if the treatment plant is to be located in the harshest climate environment. For some projects with challenges such as large treatment capacities required or exceptional space constraints, we could apply design-and-build SBR or MBBR process and plant. Otherwise, standard and modular sewage treatment systems may suit your project’s needs better.


Partnership to distribute
modular RBC systems.

We have partnered Miranda Inc. (Turkey)
for the sale and distribution of its standard
and RBC systems in the region. Based in
Ankara, Miranda is one of SKion GmbH’s
group of water/wastewater treatment
companies. It is specialised in R&D and
production of its proprietary MIRACELL
RBC modular systems.


RBC Technology.

How it simply works.

How it works simply.

Applied since 1960s, RBC process is a proven, simple and effective secondary treatment process for sewage after the removal of grits and large solids etc. The system usually consists of a series of closely spaced, parallel discs (polythene, PVC, or polystyrene) mounting on a rotating shaft. The discs rotate generally at a low speed of 3 – 5 rpm. 40% of the discs surface is submerged in sewage. Microorganisms accumulates and grows on the discs’ media surface over time. They receive oxygen during the rotation of the discs, digest pollutants in the sewage and converts it into carbon dioxides and water through a natural way. It is that simple.


Key advantages.

Compared with other conventional activated sludge processes.

  • Lower energy consumption – less than half is required.
  • Greater process performance stability against organic load variations/shocks.
  • Lower volume of solids generated.
  • Easier to operate, less operators’ attention needed.
  • Less equipment to manage, maintain and upgrade.
  • Less land space occupied.
Key advantages

RBC modules.

Look good. Work well.

A proprietary Miracell RBC module is able to handle up to 50m3/day (or for 250 Population Equivalent – PE) of sewage inflow. It consists of a fibre reinforced polyester (FRP) tank , and proprietary corrosion-proof polyethylene discs with innovative textures that grows and holds microorganisms exceptionally well for the biological process needed to treat the sewage to discharge standards.

Modular clarifier

Modular clarifier.

Compact lamella separators
for sedimentation.

Miranda’s proprietary standard and modular clarifier is designed to handle up to 200m3/day of sewage treated by Miracell modules. It can hence be added to a single Miracell module for a 50m3/day treatment capacity, or configured with up to 4 x Miracell modules upstream for maximum 200m3/day-train.

Incredibly compact.

Vital statistics and footprint dimensions.

Miracell modules are some most compact RBC systems for sewage treatment. The designs and dimensions of the modules help save substantial space required of a typical sewage plant. They are easy to be installed and inter-system connected at any project site.
