Scrubber

This eliminates the ammonia produced during the organic matter's aerobic fermentation (mainly at the composting area). A system to eliminate hydrochloric acid (in case this substance is detected) has also been projected.

Sulphuric acid is added while the air is passing through filters. The acid reacts with the ammonia and produces a liquid salt: ammonium sulphate.

If the hydrochloric acid scrubber is been used, then sodium hydroxide is added; this chemical reacts with hydrochloric acid and produces produce sodium chloride (common salt).
