The thickening module is scaled up and installed on a hydrocyclone built for carrying out on-site tests in wastewater treatment plants. This mobile hydrocyclone, originally developed for the purification of municipal solid waste for co-digestion [11], can process an inlet volume flow rate of 25 m 3 /h and is operated as a stand-alone system.
Efficient treatment and recycling of process water is one of the keys to ensure a stable operation of ethylene production plant.

Fouling is an unfortunate part of ethylene and reactive monomer production. This handy guide will give you some clues as to what's happening in your process based on the type of fouling you are seeing. Fouling and unwanted polymer formation are ongoing issues in ethylene, butadiene, and reactive monomer processing plants.
We recommend a maximum feed pressure of 125kPa for fine feed, and a maximum of 100kPa for coarse feed, to prevent excessive wear. But for fine particles or dilute feeds, the maximum pressure can be as high as 300kPa for the smaller cyclones – 400mmØ and less. Recommended maximum feed pressures are –. Cyclone Diameter.
Introduction. Hydrocyclone is used to separate particles in a liquid suspension based on the densities of the particles.
