6. SYSTEM DESCRIPTION:
A. WFI System:
The WFI system design has the following major stages of purification, distribution and control.
After Purified water then one multi column for preparation of WFI and WFI storage tank and distribution system.
B. Generation System for WFI:
From Purified water storage tank to fed the purified water in to the multicolumn. Distillation unit from the multi column the WFI produced is stored in a SS Tank which has a holding capacity 500 Litre.
The WFI kept under circulation through loop and its temperature.
The WFI is kept under circulation through a loop and it’s temperature is always maintained above 80 o C. Temperature and Conductivity sensors are fitted on the return loop line. This is a full proof system developed by Fast Pharma for the production requirement of Parenterals Preparation.
C. Storage and Distribution System Description:
The WFI, generated by water system, is fed to the “WFI storage tanks, on demand, prior to the distribution to final user points. The storage tanks capacities have been arrived at, keeping in mind the peak load & buffer volumes to be maintained.
The WFI, stored in the “WFI storage tanks, is supplied to various usage points in the plant, by means of a piping/distribution network, which is a “closed loop system”. The water piping/distribution system is being maintained at ambient temperature.
D. WFI Storage Tanks:
Water storage tanks have been provided, for Injection Block. The “WFI storage tanks have been designed as jacketed tanks, for heating with steam during sanitization. The sanitization is performed by activating a steam control valve, for maintaining the water distribution systems at an elevated temperature for a stipulated period of time.

For safe working of the water system, “water level controllers” have been provided in the storage tanks, which prevent the tanks from overflowing as well as safeguard the pumps from running dry. In case of high water level in storage tank, water can be diverted to the process water tank.
E. Conductivity Meter:
The quality parameters of WFI, such as conductivity, are continuously monitored and provide necessary control for the water system operation. In case of any deviation in the water quality, “necessary tripping/alarm” is triggered, in order to draw the attention of the system operator. For this purpose, an “online conductivity sensor” has been installed, which can actuate a drain / dump valve (on deviation from set limits) and prevent WFI from being distributed to the user points. This safeguards the users from using poor quality water.
F. WFI Distribution Loops:
WFI separate loops have been provided, parental department both the loops are identical in design and basic control systems, but are designed for the agreed user requirements for respective loops.

Evaluation of Results

Phase – 1 Result

After completion of Phase-I, Alert and Action limits of testing parameters for WFI will be calculated as per given equation and these alert and action limits will be followed for further qualification of water system.

After completion of Phase-I, water can be used for Production Purpose.

Alert levels are levels or range that, when exceeded; indicate that a process may have drifted from its normal operating condition.

Alert levels constitute a warning and do not necessarily require a corrective action.

“Alert Level = Average + 2 X Standard Deviation”

Action levels are levels or range that, when exceeded, indicate that a process has drifted from its normal operating range. Exceeding an Action level indicates that corrective action should be taken to bring the process back into its normal operating range).

“Action Level=Average + 3 X Standard Deviation”

Note: Based on the Study of Drain time, conclusion will be drawn for the period of drainage of WFI before usage during process. Based on Hold Time study, conclusion will be drawn for WFI storage period in case it is required.
