Near own wastewater treatment plant (pharmaceutical industry): one installation is installed to treat the air inside and outside the wastewater treatment building.

One diffuser treats the odour coming from the sludge thickener and four diffusers treat the area where the chamber filter press is located.

Five other atomisers are installed outside and neutralise the odour from the sludge.

Using 35 atomisers, the odour developed at the screw pumps, sand collection and pre-settling basins is significantly reduced towards the environment.

The installation is controlled by a temperature sensor, so the vaporisers only operate at temperatures above 21 °C.

When tank lorries are cleaned, the resulting waste water is passed through a biological water treatment plant (biorotor), which cleans it.

In the aeration tank of the treatment plant, H2S and NH3 odour is released, which is neutralised by means of four atomisers and enzyme deodoriser EC250.

Waste gas released periodically from an in-house water treatment plant needs to be deodorised effectively. To ensure proper treatment of the waste gas, 5 mist fans have been mounted on the walkway, which spray Ecodor EC250 product.

To this end, proper deodourisation of the waste gas takes place before the air enters the immision area (in this case, a residential area).

Sludge from water treatment (government) is stored in containers.

As the sludge containers cannot be closed during filling, and because they are set up outside, high odour loads sometimes occur.

To neutralise these odours, 6 compressed air atomisers mounted above each container are used to treat the odours. The atomisers atomise an Ecodor EC250 : water solution in a mixing ratio of 1:250.

At the ‘in-house’ water treatment of a company that processes waste, high odour loads occur at irregular times.

During these peak odour loads, 12 compressed air atomisers are used to neutralise the odour escaping through the roof.

The atomisers atomise an Ecodor EC250 : water solution in a mixing ratio of 1:250.

During dumping of sewage sludge in two sludge bunkers, high concentrations of odour components are released.

The air is extracted through extraction fans at the bottom of the bunkers. As soon as the lids of the bunkers are opened, the Ecodor deodoriser switches on automatically and then switches off again automatically after a preset time.

Both bunkers were equipped with 3 atomisers, which then neutralise the amount of odour components to an acceptable level.
