Today’s appliances and equipment are all trending toward more energy-efficient features. With more large companies focused on combating the effects of climate change and creating more sustainable operations, developing systems that do not waste as much energy is crucial.
Companies that develop reverse osmosis systems in Shelby County, OH are particularly focused on creating systems that significantly reduce the amount of water wasted. Consider this: the majority of reverse osmosis systems you’ll find on the market waste up to 20 gallons of water just to produce a single gallon of product water. There is now a new technology being experimented with, known as “ZeroWaste,” that addresses this problem by returning the concentrate water from the reverse osmosis system back to the plumbing in the home, creating a system that is able to run with 100 percent efficiency—a massive boon for homeowners and the environment alike.
When you consider the fact that millions of gallons of water get wasted by reverse osmosis systems in the United States every single day, this type of technology could have a transformative effect. Even the most efficient reverse osmosis systems used in homes will generally use four gallons for every gallon produced, but that rate isn’t generally sustainable without specialized equipment. The experiments with ZeroWaste could be the start of a new era in water filtration.
How does it work?
In your standard point of use (POU) system, there are five total stages that use three stages of pretreatment (one sediment and two carbon filtration), followed by a TFC membrane and concentrate and permeate waters that are routed to the tank and to the drain connections.
In the ZeroWaste system, the water outlet from the sediment and carbon filters gets routed instead through a solenoid valve and pump before it hits the membrane inlet. This results in filtered water being provided to the solenoid and pump, which will prevent foreign materials from damaging them. While carbon block filters are generally preferred because they result in fewer carbon fines, GAC filters can be used if flushed with water before they get hooked up to the pump.
A pressure switch is implemented to bring the system to a halt by opening up the circuit to the solenoid valve and pump. Any time the pressure in the reverse osmosis storage tank rises to a certain level that indicates the tank is full, that pressure switch will open, preventing the system from creating any more reverse osmosis water.
After this, the concentrate water gets sent back through a flow restrictor in a similar manner as before, except this time the flow restrictor size will be larger to allow for the back pressure coming from the hot water line. Larger flow restrictors can enable the pump to circulate the water at about a four to one ratio of concentrate to permeate.
