Description

The LineSig LNS-SC-BIO is a vertical packed-bed biological gas-treatment system engineered for continuous removal of water-soluble volatile organic compounds and odorous industrial emissions. Contaminated gas passes counter-current through a continuously wetted packed section where pollutants are transferred into the aqueous phase.

Specialised microorganisms subsequently metabolise the absorbed contaminants into environmentally benign end products such as carbon dioxide, water and mineral salts — a sustainable, low-chemical alternative to conventional wet chemical scrubbing.

LineSig LNS-SC-BIO biological scrubber with nutrient dosing tanks, pump and control panel

Typical contaminants

Hydrogen sulfide (H₂S), ammonia (NH₃), mercaptans, dimethyl sulfide, trimethylamine and other amines, volatile fatty acids, methanol, ethanol, acetone, formaldehyde, water-soluble VOCs and complex organic odours.

Process

How it works

Contaminated gas enters the lower portion of the scrubber
Gas flows upward through high-surface-area biological packing while recirculating liquid flows downward
Soluble contaminants transfer from the gas phase into the liquid film

Acclimated microorganisms metabolise the absorbed contaminants
A high-efficiency mist eliminator removes entrained liquid droplets
Treated gas exits through the upper stack connection
