摘要:
A method and a apparatus for treating a liquid volume containing latex waste, the method comprising providing a treatment apparatus comprising at least a first vessel, and a filtration system in liquid communication with the first vessel; delivering a portion of the liquid containing waste latex to the first vessel; adding a first reagent to the portion of liquid containing waste latex to cause the formation of waste latex flocs of a first size; adding a second reagent to the portion of liquid containing waste latex to cause growth of the waste latex flocs of the first size into separable waste latex flocs; separating the separable waste latex flocs within the filtration system into a waste latex sludge and a first filtrate; and dewatering the waste latex sludge to produce a waste latex solid and a second filtrate. The filtrates may be reusable in a latex manufacturing process.
