OCY751	WASTE WATER TREATMENT	LPTC

3003

OBJECTIVES:

• To make the student conversant with the water treatment methods including adsorption and oxidation process.
• To provide basic under standings about the requirements of water, its preliminary treatment.

UNIT I	WATER QUALITY AND PRELIMINARY TREATMENT	9

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-unit 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	9

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	9

Taste and odour control – adsorption – activated carbon treatment – removal of color – iron 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	9

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	9

Chemical process – adsorption – theory of adsorption – ion exchange process – chemical oxidation – advanced oxidation process – sludge handling and disposal – miscellaneous treatment processes.

TOTAL : 45 PERIODS

OUTCOMES:

• Will have knowledge about adsorption and oxidation process.
• Will gain idea about various methods available for water treatment.
• Will appreciate the necessity of water and acquire knowledge of preliminary treatment.
