Removal Kinetics and Performance Evaluation of 3D Rotating Cylindrical Anode Reactor for Textile Wastewater Treatment

摘要

The geochemical characteristics of groundwater in the Chittur block, Palghat, Kerala have beenstudied to assess the water quality for domestic and irrigational purposes. During pre-monsoon (April-2010) period 89 groundwater samples were collected from 61 dug wells and 28 bore wells. Chemicalanalysis of the groundwater shows different ranges for different parameters (pH 6.25-8.29, EC 250-2400 μS/cm, TDS 160-1536 mg/L, TH 65-945 mg/L, Mg2+ 3.62-189.46 mg/L, F- 0.02-6.3 mg/L, Cl- 10-672mg/L, Na+ 1-126 mg/L, K+ 1-23 mg/L, NO3- 1.42-23.15 mg/L, SO42- 5.72-159.62 mg/L and PO43- 0-2.12mg/L). High fluoride (F-) concentration is reported from 12% water samples. Piper diagram reveals that42% of the samples are MgCO3 type. Irrigational suitability of water is evaluated based on sodiumadsorption ratio, residual sodium carbonate, sodium percent, salinity hazard and USSL diagram.Salinity hazards show that 52% of the samples fall in high salinity hazard (C3) and 1% in very highsalinity hazard class (C4). The study shows that, groundwater beyond the acceptable limit of EC, TDS,TH, Mg2+ and F- are not suitable for drinking, and groundwater fall in very high salinity hazard class isnot suitable for irrigation.
