Müller AWN 600/MAASS Wastewater Neutralization/scrubber Systems

This is a completely overhauled laboratory scrubber / scrubber to connect to a fume hood. The scrubber neutralizes the air from the fume hood before it is blown out.

MAASS Vertical air washer:

Type MAASS, can be connected as an additional element next to the fume cupboard. The washing principle, which uses a newly developed bell bottom, is characterized by a particularly high efficiency with very low water and energy consumption.

The water, which serves as a washing liquid, is led to the bell bottom by a maintenance-free, low-noise circulation pump. The air extracted in the fume cupboard is led through this bell bottom and, in combination with the washing water, creates a very strong bubbling effect, so that separation levels of up to 96% of the contaminants are achieved.

The laboratory exhaust air system, type MAASS, works fully automatically and is virtually maintenance-free. The washing machine is controlled by a compact programmable controller. The wash water is automatically topped up and topped up via level control, which also protects the pump against starting and running dry. The contaminated wash water is discharged via a motorized ball valve with a large, free cross-section.

Capacity: 600 – 900 m3/h

AWN 600 Neutralization system for laboratory waste water:

The waste water neutralization type AWN can be integrated as a further element in the fume cupboard substructure. It serves to neutralize acid and/or alkaline waste water from the scrubber or from the laboratory room.

The neutralization system type AWN works according to the batch principle. The capacity is adapted for use in the laboratory with a maximum of 600l/h. The waste water is collected in the integrated collecting tank and, when the desired level is reached, transferred to the neutralization tank. Subsequently, lye or acid is dosed periodically with constant pH value registration and circulation according to the set final pH value.

The wastewater neutralization holding tank can be refilled during the neutralization process, virtually eliminating waiting times during ongoing laboratory operations. After reaching the final set pH value, the neutralized medium is pumped into the sewer via a 3-way motorized ball valve.
