turbidity, pH, hardness, alkalinity, TDS, COD and BOD, flouride and arsenic. Municipal water treatment:
primary treatment and disinfection (UV, Ozonation, break-point chlorination). Desalination of brackish
water: Reverse Osmosis. Boiler troubles: Scale and sludge, Boiler corrosion, Caustic embrittlement,
Priming &foaming. Treatment of boiler feed water: Internal treatment (phosphate, colloidal, sodium
aluminate and calgon conditioning) and External treatment – Ion exchange demineralization and zeolite
process.
UNIT II

Reduced phase rule; Construction of a simple eutectic phase diagram - Thermal analysis; Two
component system: lead-silver system - Pattinson process.
Composites: Introduction: Definition & Need for composites; Constitution: Matrix materials (Polymer
matrix, metal matrix and ceramic matrix) and Reinforcement (fiber, particulates, flakes and whiskers).
Properties and applications of: Metal matrix composites (MMC), Ceramic matrix composites and
Polymer matrix composites. Hybrid composites - definition and examples.
UNIT IV
