The present study focuses on newer biocoagulants, bioformulations, and the understanding of coagulant behavior with biocoagulants in relation to chemical coagulants. Newer seeds Azadirachta indica (AI) pads Acanthocereus tetragonus, are discussed along two known Moringa oleifera Cicer arietinum seeds. Dye removal studies were carried out using widely reported Congo red dye facilitate easy comparison other conventional coagulants effect various parameters such as initial concentration, pH,...
Wastewaters from chemical fertilizer industry mainly contain organics, alcohols, ammonia, nitrates, phosphorous, heavy metals such as cadmium and suspended solids. The nature of effluent streams varies in terms its constituents complexity. present work attempts to fill the void literature that mostly reports synthetic wastewater treatment studies, by evaluating solutions comparison different methods for real wastewaters industry. An attempt has been made devise suitable methodology using a...
Hydrodynamic cavitation for the degradation of organic solvents was investigated in detail using a newer form cavitating device‐vortex diode. The results were also compared with that conventional device orifice. Removal three different solvents—acetone, methyl ethyl ketone (MEK), and toluene studied on pilot plant capacity 1 m 3 /h. effect operating parameters such as inlet pressure, initial concentration, reactor type rate solvent detail. revealed efficiency removal varies substantially...
A novel approach is developed for desulphurization of fuels or organics without use catalyst. In this process, organic and aqueous phases are mixed in a predefined manner under ambient conditions passed through cavitating device. Vapor cavities formed the device then collapsed which generate (in-situ) oxidizing species react with sulphur moiety resulting removal from phase. work, vortex diode was used as Three solvents (n-octane, toluene n-octanol) containing known amount model compound...
The present study is an attempt to improvise the hydrodynamic cavitation methodology for effective disinfection of water and also suggest prototype development practical application. enhancement in efficiency was evaluated specifically effect pressure, temperature, pH, microbial inoculum size on different additives two model strains, gram-negative (Escherichia coli) gram-positive (Staphylococcus aureus). efficacy types flows/cavitation devices - linear flow case orifice vortex diode. diode...
The present study reports significant improvements in the removal of ammoniacal nitrogen from wastewater which is an important problem for many industries such as dyes and pigment, distilleries fisheries. Pilot plant studies (capacity, 1 m3/h) on synthetic using 4-amino phenol model containing organic compound two real industrial effluents high content were carried out hydrodynamic cavitation. Two reactor geometries evaluated increased efficiency removal-orifice vortex diode. Effect initial...
Development of newer adsorbent materials, especially from biomass, is most crucial to sustain growth otherwise well established adsorption processes that already have hundreds commercial adsorbents in practice. In the present study, and their potential-carbonaceous derived whole fruit Cassia fistula (Golden shower) been reported for applications environmental pollution control using natural, renewable biomass as precursor. The potential different forms produced by thermal chemical activation...
The present study reports, for the first time, a new and techno-economic strategy effective removal of antimicrobial resistant bacteria (AMR) difficult, opportunistic pathogen using cavitation natural oils/plant extract. A hybrid methodology oils known health benefits has been discussed in combination with conventional physico-chemical method hydrodynamic that not only provides efficient water disinfection, but also eliminates harmful effects methods such as formation disinfection...
A study was conducted to investigate the degradation of Prazosin, an Alpha-1 Adrenergic Blocker, which is commonly used in treatment Hypertension. The aimed achieve improved efficiency using Hydrodynamic Cavitation (HC) and Process Intensification. new cavitation technique that utilises Dual Activity Reactor, a vortex flow-based device, introduced study. Two different types diodes were comparative investigation: Non-Catalytic Aluminium diode Copper exhibiting catalytic properties. impact...
