IBA systems for biological purification waste water

Individual Treatment of Wastewater (IBA)
From 1 January 2005, unpurified domestic waste water must not be discharged. There are places where households do not yet have sewerage. Then, too, the waste water must be purified. This can be done via a purification facility, also called IBA. IBA stands for Individual Treatment of Wastewater.

Diederen supplies an extensive program of concrete and plastic IBA systems and supplies accessories and conversion kits to upgrade your current septic tank to any desired class. Temporary and / or mobile systems are also possible.

The systems are used, for example, in homes, farms, houseboats, campsites, bungalow parks, apartment complexes, beach tents and other situations where sewers can not or may not be discharged.

What is an IBA?
An Individual Treatment of Wastewater, in short IBA, is a system that purifies the household wastewater. It extracts sludge, suspended dust particles and biodegradable material from the water. Up to the level that is acceptable for the competent authority (municipality, water board, etc.)

IBA class 1 (Septic tank):

These are still allowed by the competent authority in exceptional cases. These are usually situations where another type of IBA is demonstrably not working. (For example, with too little waste load).

IBA class 2:

Removes suspended and sedimentable substances with oxygen.


IBA class 3a:

Same as class 2, but with (De-) nitrification (including the reduction of Ammonium and NH4 and other nitrogen compounds).


IBA class 3b:

Same class 3a, but with Defosfatering. (phasing out phosphates)
