utilization of agro Industrial waste jatropha curcas pods as an activated carbon for the adsorption of reactive dye remazol brilliant blue r rbbr
Journal of Cleaner Production, 2012Co-Authors: Palanivel Sathishkuma, Mani Arulkuma, Thayumanava PalvannaAbstract:Abstract Jatropha curcas is a non-edible oil crop predominately used to produce biodiesel. J. curcas pod contains 80% as dried vegetable and remaining 20% are seeds that are used for the biodiesel production in industries. In the present study, J. curcas pods were used for activated carbon preparation and successfully employed as adsorbent for the removal of reactive dye, Remazol Brilliant Blue R (RBBR). Batch adsorption experiments were performed as a function of contact time, pH, adsorbent dosage and initial dye concentration. The experimental results indicate that 0.2 g of activated carbon removed 95% of 50 mg L −1 dye. Adsorption data were modeled using the Langmuir and Freundlich isotherms. Langmuir isotherm was obeyed for the adsorption. Equilibrium parameter value ( R L ) was observed to be in the range of 0–1. The dye adsorption followed the pseudo-first-order kinetics model with regard to the intraparticle diffusion rate. Physico-chemical properties of activated carbon were analyzed by SEM, FTIR and XRD before and after dye adsorption. The adsorbed dye from activated carbon was successfully desorbed (80%) by 1 N NaOH. Bench scale removal of RBBR dye as well as real textile Effluent was carried out by J. curcas pods activated carbon (JCPAC). This option will make the agro-Industrial waste JCPAC adopted in textile Industrial Effluent Treatment for environmental cleansing.

novel Industrial wastewater Treatment integrated with recovery of water and salt under a zero liquid discharge concept
Reviews on environmental health, 2016Co-Authors: Sengodagounder RajamaniAbstract:: Conventional Industrial Effluent Treatment systems are designed to reduce biochemical oxygen demand (BOD), chemical oxygen demand (COD) but not total dissolved solids (TDS), mainly contributed by chlorides. In addition to the removal of TDS, it is necessary to recover water for reuse to meet the challenges of shortage of quality water. To recover water, the wastewater needs to be further treated by adopting Treatment systems including microfilters, low pressure membrane units such as ultrafiltration (UF), membrane bioreactors (MBR), etc., for the application of reverse osmosis (RO) systems. By adopting the RO system, 75%-80% of quality water with <500 mg/L of TDS is recovered from treated Effluent. The management of 20%-25% of the saline water rejected from the RO system with high TDS concentration is being addressed by methods such as forced evaporation systems. The recovery of water from domestic and Industrial waste for reuse has become a reality. The membrane system has been used for different applications. It has become mandatory to achieve zero liquid discharge (ZLD) in many states in India and other countries such as Spain, China, etc., and resulted in development of new Treatment technologies to suit the local conditions.
