PUB has been investigating methods to scale back water waste for fairly a while, starting with a research on sewage water sterilization within the 70s. By 1998, PUB had discovered a technique to deal with, reclaim, and produce sewage water for reuse with out sacrificing affordability or public well being. The sterilized water—referred to as NEWater—was first launched to uncooked water reservoirs, from which it could finally make its method into the overall water provide. Now, nevertheless, NEWater is bought for direct consumption in plastic water bottles.

The common brewery goes by means of seven gallons of water for each gallon of beer, which creates the proper atmosphere by which to check methods like PUB’s.

Sewage water first goes by means of microfiltration, which separates out microscopic particles and micro organism. Then it undergoes reverse osmosis (a typical, scalable filtration technique) that makes use of a semi-permeable membrane to permit water molecules by means of whereas holding viruses and different “undesirables” behind. Whereas these two steps alone could be enough to create a potable product, PUB sanitizes the filtered water utilizing ultraviolet gentle earlier than sending it off to Brewerkz and bottling amenities.

“NEWBrew is a showcase of the prime quality of Newater and is proof that sustainability could be scrumptious,” mentioned Tan Wee Han, proprietor and CEO of Brewerkz, throughout a media tasting in Tanah Merah.
