Sipchem Wastewater Scheme Overview
Sulfate Removal System
Stream E = 105 m3/hr
TOC = 4,000 ppm TDS = 22,000 ppm pH = 1 - 1.5
Cake for disposal Sludge
Biological System
Stream B = 47 m3/hr
TOC = 1,000 ppm TDS = 2,000 ppm pH = 5 - 11
Retention Basin
Biosludge
Final Discharge
Wastewater Discharge 125 m3/hr
TOC <800 ppm TDS <2,000 ppm pH = 5 - 11
Filtrate
Carbon Filter
Stream A = 5 m3/hr
8 m3/hr
Stream D = 28 m3/hr TOC <. 800 ppm pH = 5 - 11
Stream C = 43 m3/hr
PCR Unit 65 m3/hr

Total Wastewater flow 228 m3/hr
100 m3/hr Conductivity < 800 µS/cm TOC <. 50 ppm Ammonia < 110 ppm pH = 5 - 11
Conductivity < 50 µS/cm TOC < 20 ppm pH = 5 - 11
Process Condensate Recovery Unit
Demin Plant & Process Condensate Recovery 9
Conductivity < 1 µS/cm. Silica < 20 ppb
Seawater Ammonia <3 ppm TOC <75 ppm Free Chlorine = 0.2 - 0.5 ppm
Conductivity < 800 µS/cm TOC < 50 ppm Ammonia < 110 ppm
Challenges and Process Design Improvements
Unit Challenges Problem Improvements
Carbon Filter High Differential Pressure
Inadequate backwash Upgraded under lateral drain from flat to Spiral shape
Cation Bed High Differential Pressure
Upstream Carbon Media Fines Slippage causing resin fouling
Upgraded carbon media to higher strength's grade
Cation Bed Performance decline
Diluted Wax present in process condensate
Process Optimization and eliminate the stream containing the wax.
