Water for Injection:

Guided by: Naresh Rajgor Presented By: Hiren Pokar Water for Injection M.P. Patel College of Pharmacy, Kapadwanj , Gujarat

Flow of Content…..:

Introduction Factor Affecting To WFI Distillation Types Of WFI Distillation Unit Reverse Osmosis Storage & Distribution Flow of Content…..

PowerPoint Presentation:

Fine Sources Of Water It Should Contaminated With Natural Suspended Mineral And Organic Substance. Dissolve Mineral Salt, Colloidal Material, Viable Bacteria, Industrial Or Agricultural Chemical. Water Are Mainly Source Such As Stream, Lake. The Source Water Must Be Pretreated By One Or Combination Of Following Treatment:

PowerPoint Presentation:

- Chemical Softening - Filtration - Deionization - Corbon Adsorption - Reverse Osmosis Purification WFI Can Be Prepared By Distillation Or By Membrane Technologies ( Reverse Osmosis Or Ultrafiltration )

FACTOR AFFECTING WFI:

Quality Of Feed Water E.G Chlorine In Water Size Of Evaporator Redissolving Volatile Impurities Contamination Of The Vapour And Distillate From Metal Part Of Still FACTOR AFFECTING WFI

DISTILLATION :

Distillation Is Process Of Converting Water From Liquid To Gaseous Form. Since Steam Is Pure Gaseous Water, All Contaminants In Feed Water Are Removed. Conventional Still Consist Of Evaporator Containing Feed Water, Head Space Above The Leval Of Distilland With Condensing Surface For Refluxing Vapour. DISTILLATION

TYPES OF WFI DISTILLATION UNIT :

Two Basic Types Of Wfi Distillaton Unit 1. Vapour Compression Still 2. Multiple Effect Still TYPES OF WFI DISTILLATION UNIT

2.MULTIPLE EFFECT STILL:

2.MULTIPLE EFFECT STILL

REVERSE OSMOSIS :

REVERSE OSMOSIS

STORAGE AND DISTRIBUTION:

Closed System That Removes Micro Organisms, Dirt, And Vapours From Air As The Tank Is Filled And Emptied. They May Be Prevented By Holding The Temperature Of The Water 80 ºc By Means Of Steam Coil In Bottom Of Tank Distribution Of WFI From Storage Tank By Direct Withdrawal From The Tank Through a Pipe System . STORAGE AND DISTRIBUTION

STORAGE AND DISTRIBUTION :

Closed System With Air Exchange Through Filter That Remove Micro –Organism, And Vapours From The Air As The Tank Is Filled And Emptied ? They May Be Prevented By Holding The Temperature Of Water At 80 ºc By Steam Coil In Bottom Of Tank ? Distribution Of WFI From Storage Tank To The Point Of Use By Direct Withdrawal From The Tank Through A Pipe System. STORAGE AND DISTRIBUTION
