CHEMICALS


The chemical and petrochemical industry are of unfriendly operation condition and has high requirement of end-product quality, replacing high demonds on filtration systems and filter press structures with regard to  chemical resistance and the relevant filtration parameters to ensure the highest possible end-product quality. 

JWK offers comprehensive and sophisticated filter press technologies  in the field of solid-liquid separation and customer-oriented solutions to improve production, efficiency and end-product quality , while with feature of durable, safe and efficient technology solutions as well as optimised and efficiently designed process parameters. 

JWK chamber filter presses and membrane filter presses are the optimum solution for the specific chemical properties at filtration temperatures of -10 °C to 110 °C due to their process-technical variability.


They offer high filtration quality, high filtration rates, maximum washing efficiency and a high degree of dewatering. Furthermore, our computer-controlled regulation of the feed offers significant economic advantages in the filtration of the finest particles and the associated homogeneous filter cake. 


Important process steps of JWK filter presses are: Cleaning, filtration, dewatering, drying.
