Purified Water Generation Plant

Purified Water Generation

Purified Water is very important part of Pharma industry used for manufacturing of tablets.There are three stages of Purified Water Generation Plant.

Raw water from IDC received at company Raw water storage tank.From tank water transferred to PWG plant through centrifugal pumps while transferring water pass through sand filter.

Sand filter removes impurities,dust,durt partical from water.In PWG plant water pass through 5micron water filter and stored at storage tank.

In first stage of PWG water from storage tank pass through softener plant.In softener plant hardness of water reduced also magnesium available in water removed.After softener plant NaCl and NaOH solution added in water.NaCL for jurms killing and NaOH to reduce pH of water.Then it pass through the Ultra filter in ultra filter colliden silica removed.The filter size of ultra filter is 0.1 micron to 0.01 micron.After ultra filter water stored in primary water storage tank.

In second stage of PWG water comes from primary water storage tank through pumps.Then anti-scalent and SMBS(Sodium Meta-bisulphate) solution added in water.SMBS to remove chlorine available in water and anti-scalent for remove scale.

Then water pass through RO(Reverse osmosis) membrane with high pressure.

RO membrane filter size is 0.01 micron to 0.0001 micron.Water from RO membrane goes in EDI (Electro-Deionization) plant.In EDI plant iron present in water are removed. Water received from EDI plant stored in Purified Water storage tank.

Conductivity of water after EDI plant should not more than 1.3 micron-siemans/meter-square.If the conductivity of water after EDI plant is less than 1.3 micron-siemans/meter-square then only water is purely Purified and it is ready for the use.If the conductivity of water is more than 1.3 micron-siemans/meter-square then the water recirculated.

In third stage of PWG plant Purified Water stored in tank and transferred to the user department as per requirement.

How to control Temperature and Humidity in Air Handling Unit

How to control Temperature and Humidity in Air Handling Unit Overview Air Handling unit is a system used to supply temperature and Humidity controlled filtered air to the cleanroom. For air filtration various types of filters are used in AHU. And for temperature and Humidity controlling cooling and heating coils are provided in AHU. Goals Control the temperature of air used in the cleanroom Control the humidity of air used in cleanroom Air filters Specifications The air Handling unit consists of Air filter Cooling coil Heating coil Air blower HEPA Filter Controlling of Temperature and Humidity By Cooling Method The cooling coil recirculates the chilled water having temperatures between 4°C to 6°C. This chilled water comes from the Chiller through centrifugal pumps. When we start the Air Handling unit blowers sucks the air through the pre filters of the air Handling unit. When blowers sucks air, it passes through the cooling co...

AIR FLOW, AIR VELOCITY, ACPH, AHU CAPACITY

Air Changes per Hour AIR VELOCITY AND ACPH OF ROOM OR AREA Procedure to be followed: Air Velocity Measurement and Calculation of Air Changes: Objective : To demonstrate that the air system is balanced and capable of delivering air velocities and providing number of air changes per hour in the respective rooms as per requirement. Equipment to be used: Hotwire Anemometer or capture Hood Pre Requisite: Air Volumes through supply and return grills and filters should be adjusted as per the design requirement of Air Change Rate and Differential Pressure. Test Method : Ensure that the Supply blower of the AHU is "ON" prior to the start of the observations. For compliance of air change rate, velocity to be measured at 5 different locations to below the each terminal or Grill (Four Corners and center) with the help of calibrated Anemometer. Calculate the average velocity of the air coming from Plenum HEPA filter / supply air grill. Calculate the air...

Why ice forms at cooling coil and Suction line in Refrigeration system

Why ice forms at cooling coil and Suction line in Refrigeration system it's all about the relationship between a temperature and pressure and how the pressure affect the boiling point of the refrigerant. As the pressure of refrigerant increases then the temperature and boiling point also increases, when pressure decreased temperature and boiling point also decreases. Refrigeration and air conditioning systems take use of it to cool the air or liquid. Normal Refrigeration System In normal refrigeration system compressor compresses the refrigerant which causes the increase in pressure and temperature of refrigerant. The hot vapour refrigerant pass through the condenser in condenser heat exchange happens and refrigerant condensate into liquid forms.Before entering in the evaporator high pressure liquid refrigerant pass through the expansion of valve. The actual device used depends on the Refrigeration system but capillary t...
