Some raw feed waters contain suspended particulate material. This material is commonly sand, iron oxides, clay or elemental sulfur. Introduction of such materials into the membrane system can cause the development of excessive system differential pressure (dP), or even complete blockage of the brine channels with the resultant reduction of permeate flow. It can also cause physical damage to the membranes themselves. This usually results in a decrease of permeate quality and reduction of membrane life. Cartridge filtration is normally a simple and cost-effective way to reduce the amount of particulate matter reaching the membrane surface.

Since Harn R/O has been in the membrane treatment business for more than forty years now, we have seen our number one question from engineers and potential owners transition from “will membranes work on my water source?” to “how much will the membrane treatment plant cost?”.

Much of the environmental discussion of the new millennium has been centered on an individual’s carbon footprint. From running the shower to the continuous flow of the faucet as you brush your teeth, we have all heard statistics regarding how much water we use. Similar to our carbon footprint, we can estimate our individual water footprint.

The ISO 9001 first debuted in 1987 with the goal of helping organizations satisfy customer and stakeholder needs as well as statutory and regulatory requirements relating to their product or service. This certification has evolved over time, with regular revisions requiring associated companies to expend resources in order to maintain their certification.

Whether commercial or residential, the modern world is currently seeing an increase in water reclamation practices. Reclaimed water, perhaps better described as "recycled water," is wastewater that has been filtered and treated for reuse, thereby limiting the need for fresh water use. This practice has increased in popularity over recent years. GAO reported 36 states as using reclaimed water in 2013, compared to just 23 states in 2003.
