RO Systems

Company Reference: 

New L1-Series light commercial RO systems are ideal for a wide range of applications, including food and beverage preparation, aquariums, hydroponics, misting and more. The 200- to 300-gpd systems feature a new single-pump design, extra-low-energy membranes with auto flush, pre- and post-filtration, and a compact wall-mount space-saving design that is simple to install. They also are energy efficient. 

Membranes

Company Reference: 

New 2.5-in. HF5-Series ultra-low-energy membranes feature a low nominal operating pressure of 80 psi. The membranes can produce up to 2,500 gpd with 98.5% salt rejection for improved system performance. They are ideal for use in applications with cold feedwater temperatures, or where there is a decrease in required operating pressure. Quality tested to ensure they meet the high standards, the membranes also are manufactured in the U.S.

Beating the Desert Heat

Water scarcity is a universal and growing issue. With huge projected population growth, this problem will only continue to increase. The World Economic Forum reported that the world’s population surpassed 7 billion in 2011, and is expected to reach 9.3 billion by 2050. Urbanization, industrialization, pollution, increased energy needs and climate change all reinforce the stress of population growth, making water accessibility an even more pressing issue.

Desalination Destination

With the global population estimated to grow from 7 billion in 2011 to more than 9.5 billion by 2050, profound stress has been placed on the world’s limited water supply, not only by its burgeoning population, but also by other factors, such as rapid urbanization, industrialization, pollution and climate change.1 As water scarcity and “water stress” persist, the water treatment industry has been tasked with developing innovative solutions to produce clean, potable water.
