Important questions
share it a link alone
Don't waste my hardwork and valuable time
Don't share as screenshot kind request
most viewed dept will get update at first So Dont screenshot and share

Contact uS for more updates
*These questions are expected for the exams This may or may not be asked for exams All the best.... from admin Santhosh
Thanks for your love and support guys keep supporting and share let the Engineers know about Us and leave a comment below for better improvements If there is any doubt feel free to ask me I will clear if I can or-else I will say some solutions ..get me through WhatsApp for instant updates ~$tuff$£ctorSYllabuSUNIT I WATER QUALITY AND PRELIMINARY TREATMENT Water Quality-physical- chemical and biological parameters of water- water quality
requirement -potable water standards -wastewater effluent standards -water quality indices Water purification systems in natural systems- physical processes-chemical processes and biological processes primary, secondary and tertiary treatment-Unit operations-un processes. Mixing, clarification -sedimentation; Types; aeration and gas transfer - coagulation and flocculation, coagulation processes stability of colloids - destabilization of colloids- transport of colloidal particles, clariflocculation.
UNIT II INDUSTRIAL WATER TREATMENT
Filtration size and shape characteristics of filtering media sand filters hydraulics of filtration-design considerations - radial, upflow, highrate and multimedia filters, pressure filter. Water softening - lime soda, zeolite and demineralization processes - industrial Water
treatment for boilers.
UNIT III CONVENTIONAL TREATMENT METHODS
Taste and odour control - adsorption-activated carbon treatment - removal of color - im and manganese removal - aeration, oxidation, ion exchange and other methods = effects of fluorides - fluoridation and defluoridation-desalination - corrosion prevention and control-
factors influencing corrosion-Langelier index-corrosion control measures.
UNIT IV WASTEWATER TREATMENT
Wastewater treatment - pre and primary treatment - equalization neutralization screening and grid removal - sedimentation oil separation gas stripping of volatile organics - biological oxidation - lagoons and stabilization basins - aerated lagoons - activated sludge process-trickling filtration - anaerobic decomposition.
UNIT V ADSORPTION AND OXIDATION PROCESSES
Chemical process - adsorption - theory of adsorption - ion exchange process - chemical oxidation - advanced oxidation process - sludge handling and disposal - miscellaneous treatment processes.
