Pollo L is single-stage chemical exhaust air washer that caters to layer houses. For a large contact surface, it contains a filter element mounted horizontally in the exhaust air tower.
Our air cleaning system is monitored by conductivity sensor and pH meter, to ensure the process water reaches a pH value of ≤ 3.3, for effectively scrubbing and removing ammonia in the exhaust air. For this, the process water is sprayed onto the packing after being acidified by sulphuric acid automatically.
Ammonia present in the air is firstly dissolved into ammonium ion. The process water which contais sulphate ion, will then react with ammonium ion, and created the stable fertilizer salt called ammonium sulphate, as the end product.
