METHOD FOR MANUFACTURING TECHNICAL CARBON DISPERSION IN DEEP WASTEWATER CLEANING FROM THE PRODUCTION OF EMULSION RUBBER Russian patent published in 2017 - IPC C09C1/48 C02F1/28 C02F1/36 B01J20/20 C02F103/38 

FIELD: chemistry.

SUBSTANCE: for implementing the method, extracting of emulsifying components is carried out; the wastewater contaminants extracting from separation unit with the emulsion rubber and ultrasonic dispersing nonporous sorbent - technical carbon. First of all, a dispersion of non-porous adsorbent is obtained. It has a specific surface area of 40-150 m²/g, an ultrasonic disperser having a specific flow capacity of 250-500 W/dm³ for 10-60 seconds to mix with a low-concentration drain from node isolation rubber emulsion, followed by its concentration on the ultrafiltration unit to a content 5-12.5 wt %. The dispersion is then mixed with the waste water in the next ultrasonic disperser with a specific power of 250-500 W/dm³ for 10-60 sec with further concentration to ultrafiltration unit to a content of 10-25 wt %. Number of steps of ultrasound treatment and concentration is from 2 to 5.

EFFECT: obtaining a stable aqueous dispersion of technical carbon in obtaining the soot-filled rubbers, thus enhancing the technical and economic indices of production of emulsion rubber and hold deep cleaning of wastewater.
