VACUUM WATER DEAERATION VWD

VACUUM WATER DEAERATION

The Vacuum Water Degassing (VWD) deaerates water down to a residual oxygen concentration below 10 ppb. Optionally the water can be cooled down, filtered or sterilized with ultraviolet light. The function of the unit can be monitored and documented by an in-line oxygen analyzer at the outlet of the unit.

The process is employed in the brewing, beverage, food and chemical-pharmaceutical industries, wherever water with lowest oxygen content is required to assure high product quality and stability. The system is characterized by high operational reliability, low CO2 and energy consumption.

ADVANTAGES AND FUNCTIONS

  • Vacuum water degassing by stripping with CO2
  • Very low residual oxygen values < 10 ppb
  • Low CO2 consumption
  • Low energy consumption
  • Optional In-line oxygen analyzer, filtration or carbonization
  • Hygienic design, full CIP capability
  • Easy operation, low maintenance effort, long service life
  • Fully automatic operation with standard PLC and touch panel
  • Optional integration in process control system and remote maintenance
  • Individually dimensioned and designed for each specific application
  • Equipment and components according to customer specification
  • Compact tubular-frame system (skid mounted)

TECHNICAL DESCRIPTION

The water is distributed homogeneously to the structured packing at the top of the column. The CO2 is fed in at the bottom of the column. The water slowly flows downwards through the structured packing in counter current flow to the CO2.

A long and intensive contact between water and stripping gas is ensured by the high-performance structured packing. CO2 is dissolved in the water up to a level of 0.2 g/l and at the same time suppresses the oxygen. The operation of the column under vacuum, with a pressure about 80 mbar, reduces the partial pressure of gas. Low oxygen values and CO2-consumption are reached. Optionally, nitrogen can be used as stripping gas. The deaerated water is pumped out of the bottom of the column with a frequency-controlled pump. Optionally the water can be cooled down in a plate heat exchanger by glycol or ammonia.

Sensors for oxygen, level, flow and temperature monitor the proper functioning of the system.
The unit can be controlled by a local PLC with a touch panel or by a process control system.
Designed for high hygienic standards, all common cleaning agents in the beverage and chemical-pharmaceutical industry can be used for CIP cleaning.

TECHNICAL SPECIFICATION

 
Capacity25 to 1,000 hl/h / 2.5 to 100 m3/h
Residual oxygen content< 10 ppb / 0.01 ppm
CO2 consumption0.3 g/l

COLD WATER DEAERATION CWD

COLD WATER DEAERATION

The Cold Water Deaeration (CWD) deaerates water down to a residual oxygen concentration below 50 ppb. At the same time the water is saturated with 2 g/l CO2. Optionally it can be cooled down, filtered or sterilized with ultraviolet light. The function of the unit can be monitored and documented by an in-line oxygen analyzer at the outlet of the unit.

The process is employed in the brewing, beverage, food and chemical-pharmaceutical industries, wherever water with low oxygen content is required to assure high product quality and stability. The system is characterized by high operational reliability, simple functionality and low investments. Due to the carbonization of water, the unit is especially suitable for the production of carbonated beverages.

ADVANTAGES AND FUNCTIONS

  • Cold water deaeration by stripping with CO2
  • Low residual oxygen values < 50 ppb
  • Simultaneous carbonation of the water
  • Low energy consumption
  • Optional In-line oxygen analyzer, filtration or carbonization
  • Hygienic design, full CIP capability
  • Easy operation, low maintenance effort, long service life
  • Fully automatic operation with standard PLC and touch panel
  • Fully automatic operation with standard PLC and touch panel
  • Individually dimensioned and designed for each specific application
  • Equipment and components according to customer specification
  • Compact tubular-frame system (skid mounted)

TECHNICAL DESCRIPTION

DEGASSING

DEGASSING OF LIQUIDS

Oxygen – known in breweries as the greatest enemy of beer. It leads to oxidation, changes the aroma profile of the beer negatively and impairs its shelf life. It is therefore important to prevent oxygen from getting into the finished beer at all stages. However, this is only possible if the water with which the beer comes into contact or with which the beer is blended is also oxygen-free. For this reason, the water used must always be reliably degassed. The possibilities for this are manifold, and the results are correspondingly manifold. Take a look at the different solutions we have developed over the years and which are used by many customers worldwide.

OUR SOLUTIONS FOR WATER DEGASSING

The search for the right water degassing system can be difficult. If you have any questions or would like advice, our specialists will be happy to assist you.

FRISTAM FPM / FSM

FRISTAM FPM / FSM

CENTRIFUGAL PUMP

Specifically suited for transferring toxic, dangerous and WHC goods. These magnetically coupled pumps are designed for applications with special safety requirements. The open impeller is connected to the driving unit via a magnetic coupling that is contact-free. The product space is hermetically sealed from the environment by a separating can.

The Fristam FSM is available as a shear pump featuring a combination of rotor and stator that produces homogenised multiphase products of supreme quality.

SPECIFIC CONSTRUCTION

The pump’s power is transmitted from the drive shaft contact-free via the magnetic coupling. This ensures that the pump’s speed always corresponds to the drive speed. Thanks to the special bearings of the magnetic coupling’s internal rotor, only the drive speed is transmitted to the drive shaft, avoiding any undesirable forces.

TECHNICAL DETAILS

  • No mechanical seal; no need for a locking or supply system
  • Hermetic sealing between prod- uct and atmosphere
