Operating Principle of the Wet Scrubber System SALIX

The waste gases are fed by up to twelve separate inlets into pre-scrubber using spray nozzles which eliminates any clogging at the input. The waste gases pass into the first scrubber stage and flow upwards through the first scrubber column filled with packing material. The column is supplied with the scrubbing liquid via spray nozzles. Due to the large surface of the packing material and the counter flow principle the optimal absorption of the waste gases is possible.

In the second stage a different scrubbing liquid is used. A demister is used to prevent the liquids from the two stages from mixing. The second scrubbing liquid allows an alternative chemistry to be used and so optimise the scrubbing of the waste gases. Ingredients of waste gases, which have not reacted in the first scrubber stage, can be better absorbed in the second scrubber stage. After the deposition of residual moisture of the gas flow in a demister the residual gases meet the strict standards of German air pollution law (TA Luft).

Operating Principle of STYRAX Waste Gas Treatment Systems

Hazardous substances of process waste gases are treated directly from where they originate (Point-of-Use). In this optimized burn/wet technology the gases are burnt from top to bottom. Depending on the chemical composition of the waste gases, various reactions take place (oxidation, reduction, pyrolysis). A fluid wall/film prevents corrosion and deposition of particles in the reactor. In the washing column next to the reactor, soluble components are absorbed and particles suspended. The scrubbing liquid cools down and neutralises combustion products such as hydrogen halides. With the application of STYRAX within a holistic abatement concepts, manufacturers in the high-tech industry will meet the strict standards of the German air pollution law (TA Luft).

Flexible, Reliable & Economical in Operation — DAS Complete Solutions for Biological Wastewater Treatment using the MBBR Process

The MBBR process (fluidised bed process) is a technology for biological wastewater treatment. In this process, microorganisms are cultivated as a biofilm on carrier material. These microorganisms are responsible for the degradation of both organic wastewater constituents and nitrogen compounds. Due to the microorganisms living in biofilms, the MBBR treatment process is very robust and much more stable than other biological treatment technologies.

All MBBR Systems offer the Following Advantages:

• Compact biological treatment process
• High performance
• Simple operation
• High stability even under difficult operating conditions
• Low production of excess sludge
• No recirculation of biomass
