Project Background:  

       A pesticide company in Chongqing originally used PP hollow fiber membrane deammonia nitrogen removal system, PP hollow fiber membrane deammonia nitrogen removal system trial run.One week after the trial operation of the PP membrane irreversible wetting, penetration phenomenon, the need for ammonia removal system transformation, after site tests and a comprehensive comparison of the final choice of our PTFE hollow fiber membrane deamination.After on-site test and comprehensive comparison, we finally selected our PTFE hollow fiber membrane deammonia nitrogen removal system.

Operation situation:

Project scale: 100t/d

Inlet water quality: ammonia nitrogen is 2000-5000mg/L, COD is 10000-30000mg/L.

Effluent water quality: effluent ammonia nitrogen ≤ 100mg / L (to meet the requirements of subsequent biochemical treatment)

Membrane deammonia device main technical parameters: three-stage tandem, 8 / level

Absorbent liquid/by-product: sulfuric acid/ammonium sulfate
