Packaged Sewage Treatment Plants

The market leader for containers made from PE, top quality SBR-treatment (Sequence Batch Reactor), systems for clear water seepage. Safeguard for the future with European approval EN 12566-3.

We are proud of our high quality products which not only offer you long guarantees, key design features, excellent accessories, and a choice of systems, but also competitive pricing. Whether it's a complete new system, or utilising an existing septic tank by retro-fitting our SBR treatment equipment, we have an option to suit your specific requirements.

The MONOfluido offers safe plant technology and is very easy to handle. Compact SBR systems such as the FLUIDO are the technology of the future and today they are the most specified systems. Combined with our container MONOLITH (with 20 years guarantee) you obtain a fully biological domestic wastewater treatment plant with guaranteed long life and reliable operation. It is a compact, light and easy to install unit. The current regulations are achieved and usually surpassed.

How it works

SBR technology works with at least two separate sections: a pre-treatment chamber as buffer and sludge reservoir, and the SBR bioreactor chamber.

The wastewater stored in the pre-treatment container (1) is lead intermittently (in batches) into the SBR reactor (2) for an 8-hour aeration cycle. The submersible aerator provides oxygen and enables microorganisms to grow. These feed on the substances contained in the wastewater. You obtain ‘living’ microbiological sludge flakes that sink to the bottom of the container. In the upper part you have mostly treated water which is being pumped into the seepage or soak away area. Meanwhile a new amount of wastewater has been stored in the pre-treatment section and the cycle begins again.

The FLUIDO floating treatment system (3) is at the heart of every MONOfluido system. It treats sewage reliably and is simple to install and maintain. SBR treatment systems with submersible aerators are the most frequently used systems for small biological treatment works. With the float principle we have improved the process and this combined with the unbeatable advantages of our PE treatment tanks MONOLITH, and the MONOfluido, you are on the safe side.

If there is no stream or ditch to receive your fully biologically treated wastewater you can sily seep it below ground using our seepage systems (4). All you need is a permeable soil and sufficient distance to the groundwater level. Our treatment box is installed directly into the soil without need for gravel. This saves you 1.5t of gravel.

We also supply, install and maintain the C&A range of packaged sewage treatment plants.

The fixed bed sewage treatment plant is a variation of the well known activated sludge process which has been known for decades especially in communal sewage treatment plants. The fixed bed is a plastic tube system and is immersed in water. The surface of this tube system offers micro organisms an ideal area for growth. A compressor intermittently supplies air to the water which gives the micro organisms optimal living conditions on the fixed bed.

As this is a rather sensitive sewage treatment system which can cope with load variations and overload, it is absolutely necessary to take into account the exact quantity of sewage water / number of population to allow for buffer tanks. Regular maintenance is likewise essential to make sure, should there be any problems, immediate action can be taken, e.g. to change the aeration cycle if necessary.

As long as the maintenance instructions are observed, fixed bed sewage treatment plants are a reliable and trouble-free form of treatment.
