PHOENIX PULP AND PAPER, KHON KAEN MILL, THAILAND
Founded in 1975, Phoenix Pulp & Paper is a leading integrated producer of paper products with the capacity to produce 230,000 tonnes of pulp per year from locally harvested eucalyptus and bamboo; the process can generate over 13.5 million cubic meters of wastewater per year.
Brief
Previously responsible for discharging toxic effluents into riverways and surrounding land, the mill recognized that the tightening of environmental requirements necessitated innovative engineering and state of- the-art technologies to meeting the new standards.
Solution
Phoenix selected Flootech’s process combination of the FlooBed MBBR and activated sludge process as its wastewater solution. This FlooBed BAS wastewater treatment process was a turnkey delivery, and included screening up to wastewater tertiary treatment and sludge handling, as well as process instrumentation and automation.
The main unit processes comprised our robust primary and secondary clarifiers, known for their enhanced efficiency in solids removal and capability to produce highly concentrated sludge suitable for dewatering without separate thickening. The FlooBed MBBR ensures low and stable loading into the activated sludge process; because of requirements for extremely high quality treated wastewater, tertiary polishing via FlooDaf Microflotation was also incorporated.
Outcome
Wastewater flow to the plant was designed to be 15,000 m3/d with inlet COD and BOD concentrations of 2200 and 1200 mg/l, respectively. Right from start-up, treated wastewater quality has been excellent, and during the first months of operation the average treated water BOD was below 10 mg/l, SS < 15 mg/l and the outlet COD was as low as >40 mg/l. Since switch-on of the new plant, it has continued to operate trouble-free and within its operational parameters.
BOD COD
Raw water < 1000 mg/l < 1500mg/L
Treated water < 10 mg/l < 100mg/L
How we created value
• Low residual concentrations.
• Stable discharge water quality (with fluctuating inlet load).
• Excellent handling performance for toxic compounds and load variations.
• Low sludge production.
