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.

flootech wastewater treatment solution Today, industrial plants are taking full responsibility for the way their process waters affect production and the environment. Fresh water taken from nature is cleaned, utilized and recycled carefully within the processes and, when returned to nature, that water must meet stringent standards. These targets can be achieved using FlooBed-based biological treatment solutions.
flootech biological treatment solution Biological treatment removes dissolved organic hydrocarbons from water. Flootech’s sophisticated, compact Floobed® Moving Bed Biofilm Reactor (MBBR) uses special, freely moving biofilm carriers, which suit high capacity operations, are particularly tolerant of variations in feed flow rate and quality, and give consistently high quality results.
flootech sludge handling solution When wastewater is treated either biologically or through physical/chemical methods, sludge is produced. The disposal method for the sludge and the associated costs can significantly affect the payback and economics of a wastewater treatment plant installation. Flootech has experience treating sludges from all types of municipal and industrial wastewater systems and is able to offer solids handling equipment for sludge thickening or dewatering.
flootech chemical handling solution Correct chemical storage and dosing is essential to the proper operation of industrial and municipal water and wastewater treatment plants. The correct selection of chemicals, chemical dose rate and mixing parameters is critical and has a direct impact on the availability, performance and service life of process equipment.
flootech parts and services solution Flootech is proud to supply complete processes and to provide the diverse knowledge and expertise required to ensure that the plant and processes operate reliably. We target at optimized process results and economical operational costs at the customer’s plant. Customer satisfaction is our first priority. A delivery from Flootech ensures close cooperation with the customer starting from the evaluation of the best technological solution to installation, process optimization, training and start-up as well as after sales services covering spare part support and maintenance.

flootech floodaf technology Dissolved Air Flotation (also known as microflotation) is a well-known method of particle separation. Microbubbles are created by dissolving air into water under pressure. When the air-saturated pressurized water is released, microbubbles are formed. Chemical, physical and electrical forces cause suspended solids and colloids to attach to one another and to air bubbles. These particle flocs then float to the water’s surface and are scraped off. Coagulation and / or flocculation chemicals are used to enhance the process.
