Water Deaeration (WDS)
Pentair Water Deaeration System WDS is based on our long experience in the area of gas/liquid stripping technology. The water deaeration system is based on stripping technology with the help of CO2
, either at a temperature of 72 °C, or at ambient temperature.
The water deaeration system is a skid-mounted system, it consists of proven components, and includes all required piping, wiring and control systems. The hygienic, fully automated and reliable design guarantees easy handling, low maintenance and a long service life.
Water enters the top of the stripping column and is led through specially designed packing with a large contact surface area. CO2 is injected at the bottom and travels in counter flow, resulting in a highly efficient removal of air. The deaerated water is subsequently cooled down to a temperature of 2 °C.
Beer Membrane Filter (BMF)
A Beer Membrane Filter (BMF) makes use of proprietary membrane technology. A membrane is a thin polymer layer with pores working as a sieve in the shape of a fiber. Turbidities like yeast and proteins are retained while beer flows through the pores. The membrane is used for many filter run-cycles, which is possible because of an optimized cleaning protocol. The membrane is made from poly ethersulphon (PES) which is known for its great compatibility with food & beverages, and can withstand cleaning agents and high temperatures. Thousands of membrane fibers form a module, and 4-18 modules are packed to a membrane unit.
Typically, Pentair’s BMF system consists of an unfiltered beer tank, the membrane filter system, and a filtered beer tank, along with a designated cleaning agent cabinet. In existing breweries, reuse of the current tanks in the filter line is possible, which helps minimize capital expenditures.
BMF systems offer unique features with the PES membranes, the optimized filtration process, and the ideal cleaning procedure. The optimized filtration process withstands large amounts of yeast, and yeast even has a positive effect on the run volumes. Because of this, preclarification of beer with a centrifuge is not necessary. These solution features help breweries save on Capex and energy use, plus help avoid expensive maintenance costs. As a result, the brewery benefits in the areas of sustainability, quality, operation, and expenditures.
