Experimental investigation on sludge conditioning and dewatering using an agricultural biomass coupled with resource recovery.

In this study, the effect of modified areca husk fibre biochar (MAFB-AlCl) on dairy sludge conditioning and dewatering along with raw and modified coconut shell biochar (MCSB-FeCl) was investigated. Further, MgO impregnated biochars of areca husk fibre and coconut shells was carried out to evaluate the performance on phosphate recovery from the diary sludge. The enhancement in sludge dewatering with MAFB-AlCl were evaluated experimentally and significant reduction of capillary suction time (CST) (51.

Experimental investigation for treating ibuprofen and triclosan by biosurfactant from domestic wastewater.

The presence of emerging pollutants of pharmaceutical products and personal care products (PPCPs) in the aquatic environment overspreads the threat on living beings. Bioremediation is a promising option for treating wastewater. In the present study, an experimental investigation was carried out to produce a biosurfactant by Pseudomonas aeruginosa (MTCC 1688) for the removal of Ibuprofen (IBU) and Triclosan (TCS) from domestic wastewater.

Experimental investigation on sludge dewatering using granulated blast furnace slag as skeleton material.

The highly compressible nature of sludge and the presence of colloidal particles cause difficulties in sludge dewatering. Reducing the moisture content in secondary sludge is a key factor in reducing the capital costs, operational costs, and transportation costs in wastewater management. This investigation concerned the combined utilization of quicklime and granulated blast furnace slag (GBFS) to improve sludge dewatering.

Novel application of maghemite nanoparticles coated bacteria for the removal of cadmium from aqueous solution.

Heavy metals are classified as persistent pollutants owing to their nature of bioaccumulation and affect human life and environment, even in minor concentrations. Divalent Cadmium (Cd) is one of the heavy metal pollutants that are highly toxic. The present study investigates the novel application of maghemite nanoparticles coated Bacillus subtilis for the removal of Cd ions from its aqueous solution by batch adsorption studies.

Degradation of Triclosan from Domestic Wastewater by Biosurfactant Produced from Bacillus licheniformis.

The use of triclosan (TCS), an antimicrobial agent in consumer product, results in adverse effects on the environment due to its wide usage all over the world. The present study focused on TCS detection and attempted for degradation by biosurfactant produced by Bacillus licheniformis from domestic wastewater in Surathkal region, Karnataka, India. The experimental investigation includes biosurfactant production using crude sunflower oil and detection and degradation of TCS from wastewater by High-Performance Liquid Chromatography (HPLC).
