Abstract

The possibility of purifying wastewaters from production of glass fibre contaminated with “paraffin emulsion” oiling agent by adsorption of organic substances with Askania bentonite clay was demonstrated. The optimum regime for purification of wastewaters was selected: mixing time of 30±10 min at 50 rpm and 10 min in a rotor-jet mixing installation; mixing and settling temperature of 25±5°C, duration of phase separation of no less than 24 h. A detail design and technological regulations for purification of wastewaters contaminated with oiling agent from production of glass and basalt fibre were developed. The proposed purification technology is no-waste technology. The quality of the purified water satisfies the requirements set for circulating water system water, which allows converting to a closed cycle of use of the water. The sludge is used after purification as a plasticizing additive in production of construction materials.
