The main source of water to the plant is from underground. The water is extracted thru bore well and is pumped to an underground tank which has a capacity of 135 KL. From the underground tank the water is pumped to an over head tank. During the course of pumping to the OHT, chlorine dosing of 3 to 5 ppm is carried on line to have a control on the bio load. From the over head tank, the water passes to the Softener Plant where the water gets softened and is used for Boiler, Chillers & Cooling Towers.
This softened water enters the Purification of Water System, which constitutes of RO1, RO2, EDI, UV & Ultra Filtration Units where it gets converted to Purified Water. This water is stored in SS 316L tank with a capacity of 5KL at an ambient temperature under constant circulation loop.
Purified Water is used for preliminary washing of all manufacturing equipments & dress materials. This Purified Water acts as input water for the generation of Water for Injection. The WFI is generated with the help Multi Effect Distillation Still which has 5 Columns.
The WFI so generated is stored in SS 316L tank with a capacity of 3KL at an elevated temperature of NLT 80°C under constant circulation loop. The return loop is monitored for the Temperature (NLT 70°C) & Conductivity (NLT 1.3µsim).
WFI is used in the manufacture of Products, Final rinse of all manufacturing equipments, Dress Materials & Quality Control Equipments. The Purified Water acts as input water for the generation of Pure Steam. Pure Steam is generated with the help Pure Steam Generator.The Pure Steam is used in Autoclaves for the sterilization of materials that come directly in contact with the products.
The Whole Water System is well Qualified with respect DQ, IQ, OQ & PQ. The Water System stands Validated for Phase1, Phase2 & Phase 3 which is ongoing. All types of water are periodically monitored for the seasonal variations. Based on these Alert & Action limits, Regeneration & Sanitization frequency have been established.
The Nitrogen Gas generated is of 99.99% purity which is generated from Compressed Air employing de-oxo or purification units. With this system a very high purity of Nitrogen, free from moisture & hydrogen, is generated. The equipment’s used in the plant are in accordance with ASME/IS 2825.The capacity of generation of Nitrogen is 10 m³ /Hour.
The special features of the Nitrogen Gas Plant:
- On site Nitrogen Generation from compressed Air
- Online Oxygen Analyser
- Low Cost Nitrogen Generation
- Refrigeration dryer employed for avoiding purge air loss
The compressed air available at site is oil free, compressed at 40 °C and 7.5 kg/cm².Compressed Air Treatment (CAT) unit is installed to generate high quality compressed air for the Nitrogen Plant.
CAT comprises of 5 stage purification
- An after cooler
- Air Receiver – Wet
- Moisture Separator – Mechanical Type
- Candle Filter
- Fine Filter – For Dust
At the CAT outlet, compressed air is at atmospheric temperature and free from oil, dust and physical moisture. This acts as an in feed to the Nitrogen Generation Plant.
