PROJECT TITLE:
Primary brine purification project
Chlor-alkali industry
Process plant – 4.2MLD
Problem Statement
A leading Manufacturer of Chlor –Alkali derivatives in South Africa pursued new technology to reduce the amount of suspended solids in their primary brine purification system. The objective of the technology would eliminate the use of Barium in its current manufacturing process, which would lead to a more environmentally-friendly process with better profits.
Solution
Watericon, together with the customer, investigated updated ceramic membrane technology and trialled this technology on the customer’s premises over a period of 12 months.
Plant Feed
High temperature brine (55 – 65 °C) with a salt content of ± 300 g/L
Performance Target
● 160 m3/hr plant production
● High quality outlet brine
● TSS reduction
● pH between 9 – 11
Process
Chemical addition
Reaction tanks
Coarse filtration
Ceramic membrane cross-flow filtration
Sludge dewatering
Innovation
Watericon successfully implemented new cutting edge technology; a first in Africa using cross-flow ceramic membrane filtration within the Chlor-alkali production industry.
