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

40 m3/hr

DMW Plant

35 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.

What is The Next Ambition?

Further reduction of wastewater by 65%. Supplementary savings of fresh water intake by 20%.

Conclusion

Not only get the SAVINGS (1.80 M $) but most importantly it’s

Preserving the Natural Resources

“BEING BETTER HUMANS ”
