There are currently around 16,000 desalination plants operating across 177 countries, producing 70 million cubic litres of drinking water equivalent to almost half the average flow of water over the Niagara falls.
Basic desalination has been around for decades but is costly and damaging. The dense brine can cause serious environmental degradation and destroy marine life. The intense energy use, averaging around 3kw per tonne of water produced, matches the energy used for 20 million households. It also leaves a heavy carbon footprint.
BPT is pioneering Hydraulic and Osmotically Assisted Reverse Osmosis; an innovative approach that boosts drinking water production by 50%.
