Sulfate Removal

Population growth and the need for sustainable urban development as well as lack of water resources due to the position of Iran in the arid and semi-arid zone and the occurrence of recent drought has seriously raised the importance of water scarcity. Nowadays, unconventional water resources are considered as one of the possible solutions to provide water supplies. Among different resources of unconventional waters, the use of wastewater as a sustainable resource for water scarcity management is considered as a strategic strategy. The aim of this study was to compare biological treatment method and nanofiltration method to remove sulfate from industrial wastewater. Thus, industrial wastewater of Najaf Abad treatment plant was used for this purpose and the experiments were carried out for 11 weeks and 11 replications. The appropriate method was chosen by calculating the removal percentage of various parameters and SPSS software was used to analyze the significance of the difference between the results of the two methods. According to the results, the percentage of sulfate removal in all experiments in the nanofiltration system was higher than the biological system and nanofiltration method is more reliable to remove sulfate. So, nanofilter system would be a good alternative for the biological system to reduce and remove sulfate in industrial wastewater.

This study was performed to evaluate the efficiency of tapioca processing wastewater treatment using aerobic biofilter with variety of biofilter media: coir, coal, PVC plastic and Bio - Ball BB15 plastic. Research results in the lab demonstrated all four aerobic biofilter models processed can treated completely N and COD which COD reached 90-98% and N reached 61-92%, respectively, at the organic loading rates in range of 0.5, 1, 1.5 and 2 kgCOD/m3.day. The results identified coir filter was the best in four researched materials with removal COD and specific substract utilization rate can reach 98%, and 0.6 kg COD/kgVSS.day. Research results open the new prospects for the application of the cheap materials, available for wastewater treatment.

A cross was made between high yielding salt susceptible BINA variety (Binadhan-5) with salt tolerant rice landrace (Harkuch) to identify salt tolerant rice lines. Thirty six F3 rice lines of Binadhan-5 x Harkuch were tested for salinity tolerance at the seedling stage in hydroponic system using nutrient solution. In F3 population, six lines were found as salt tolerant and 10 lines were moderately tolerant based on phenotypic screening at the seedling stage. Twelve SSR markers were used for parental survey and among them three polymorphic SSR markers viz., OSR34, RM443 and RM169 were selected to evaluate 26 F3 rice lines for salt tolerance. With respect to marker OSR34, 15 lines were identified as salt tolerant, 9 lines were susceptible and 2 lines were heterozygous. While RM443 identified 3 tolerant, 14 susceptible and 9 heterozygous rice lines. Eight tolerant, 11 susceptible and 7 heterozygous lines were identified with the marker RM169. Thus the tested markers could be efficiently used for tagging salt tolerant genes in marker-assisted breeding programme.DOI: http://dx.doi.org/10.3329/pa.v19i2.16929 Progress.
