| Abstract | Pulp and Paper industry and associated production factories are well known to produce aggressive chemically rich effluents. Most frequently, and particularly in the developing world, such productions do not have proper wastewater treatment while discharge of untreated or poorly treated chemicals compromise natural streams. The study concerned a Thailand hardboard production factory with a minimal treatment of its effluent. This research study concentrated on development of the integrated wastewater treatment for the hardboard production factory which wastewater treatment only recentl y consisted of one shallow pond/wetland of insufficient size. The developed wastewater treatment system was proposed to involve a 3 - pond series as compared to originally existing one shallow pond (incorporating duckweed treatment). The system was practical ly developed at full scale through consecutive introduction of (i) sludge separation/disposal as the 1st stage; (ii) deepening of the original (currently 2nd) pond (iii) and introduction of the 3rd vege tated pond (meandering wetland). After implementation , the wastewater treatment efficiency of the integrated pond system was found to be significant with regard to the removal of Total Solids (TS), Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD 5 ). It was also fairly efficient with regard to removal of Phosphate, Ammonia/Ammonium Nitrogen, Nitrate - N and Arsenic. The study further emphasized the importance of relationship between maintenance of the integrated treatment system and treatment efficiency. The results showed that the discharged fina l treated effluent was significantly lower than the Thai standards, with BOD 5 and COD values being 60 ppm and 169 ppm, respectively. The effluent is characterized by Total Solids value 501 ppm, NH 3 - N 3.9 ppm, nitrate - N 0.3 ppm, NH 4 - N 4.5 ppm, phosphate 1.0 ppm and Arsenic 0.001 ppm. Therefore, the integrated system introduced at the factory as a result of the present research meets the standard of Thailand industrial discharge as far as its final effluent, currently discharged into Mae Klong river is concer ned. As the system’s operation uses minimal chemicals, labour and energy, it is an appropriate, environmental friendly and sustainable treatment system for wastewater from hardboard production useful for other similar factories across Thailand. |
