Brackish Water Reverse Osmosis: Purifying the Next Best Water Source

The safety and stability of the world’s water supplies have become a pressing political and economic issue so much so that the threat to this essential resource could yet pose a present danger to the global economy. With unprecedented climate changes comes a torrent of environmental impacts like drought, over flooding, and fluctuating sea levels, which threaten the availability and hygienic properties of potable water. Add that to the ever swelling population, along with the demand, and you’ve got a global-scale problem brewing. As surface water sources continue to dwindle due to the current drought conditions in California, brackish water may soon become the next best viable source. This extremely salty water source is known to occur in coastal areas and aquifers where there is a confluence of fresh water and saline water.

The Crossflow Filtration: New Reverse Osmosis Machine for Businesses

In many nations across the world, the simple, inexpensive reverse osmosis (RO) process has helped people in both the commercial and residential sectors to attain an adequate supply of clean drinking water for many years now. Desalination, converting saltwater into potable fluids, has become a reality because of RO systems. RO is currently the most effective solution to supply drinking water to drought-stricken areas or places with inadequate supply of potable water. The RO system extracts inorganic solids (such as salts) from a solution like seawater, for instance, to turn seawater into more potable form. Highly concentrated water is pushed through a semi permeable membrane, filtering impurities and contaminates, and allowing only water to pass through.

Using Reverse Osmosis Filter to Provide Homes with Clean Tap Water

With the seeming rapid depletion of potable water on Earth, nations are scrambling for viable water sources to resolve the growing severity of the problem. The U.S. state of California, for one, has turned to the largest body of water, the Pacific Ocean, for the key to end the state’s progressive struggle with drought. The Golden State’s extreme drought is now on its fourth year, according to NBC News, and so far, much of the state’s hopes lie in how to turn the vast amounts of seawater into drinking water. This fall, the Poseidon Water in Carlsbad, San Diego, will provide around 50 million gallons of water to Californian communities. This is reportedly the largest desalination plant in the West Coast, costing more than $1 billion to build. This is not the first desalination plant in the state, though.

Advantages of Reverse Osmosis Systems

Many businesses and homes alike have benefited from reverse osmosis systems, as scores of people move toward a health-conscious lifestyle and seek to purify their food and water supplies. Reverse osmosis is a process which can help in that endeavor.

Carbon Boosts the Flexibility of Reverse Osmosis Water Filter Systems

Carbon filtration is considered one of the relatively cheap and efficient ways of purifying water. Carbon filters themselves are highly touted for their performance, mainly due to their physical characteristics. A single pound of carbon possesses an approximate surface area of about 125 acres, allowing it to absorb a huge amount of pollutants in water. This quality is one of the factors that make carbon filters an important part of many reverse osmosis water filter systems. Activated carbon filters are also known as activated charcoal filters. The material is charcoal that has been oxygen-treated to make it highly porous with a large surface area—properties that allow it to absorb significant amounts of water contaminants. When water passes over the carbon, pollutants in the water quite literally “stick” to the activated carbon, and effectively get removed from the water.

How Using the Right RO Membrane Gives You the Beer Flavor You Desire

When sipping a pint of beer, you likely notice things like hop, malt flavors, the fruity or spicy tastes, or the acidity; and if you’re a home brewer, you’re probably taking mental notes about such details as yeast strains or the length of the secondary fermentation. What may have escaped your scrutiny is the quality of the water that was used in brewing. Water quality is often overlooked, despite being the most abundant ingredient in beer, and therefore, an important factor affecting the brew’s flavor. Beer is essentially 95% water, so it’s easy to see that when you use “good" water, you’ll produce good beer. As experts say, no amount of tasty malts and good-smelling hops will help make bad water good. Water is also the only ingredient which stays relatively unchanged from the early stages of the brewing process down to the final beverage.

Pretreatment Essential to RO Membrane Success

The United States Environmental Protection Agency classifies chlorine as a disinfectant and allows a maximum contaminant level goal (MCLG) of four milligrams per liter (mg/L) in drinking water supplies. The agency does recognize that chlorine’s presence in water can cause digestive discomfort and eye or nose irritation in some consumers. For most residential and medicinal purposes, four mg/L or ppm is unacceptable. Furthermore, the chlorine in public drinking water supplies is damaging to the membranes in a reverse osmosis (RO) system.

Since the membranes are typically the most costly part of a water filtration system, it is best to remove as much chlorine as possible from the water before it even touches an RO membrane.

: Simple and Inexpensive

This is where carbon pretreatment earns its keep. Although technically not part of the reverse osmosis
process, one or more carbon pretreatments to remove harmful chlorine is essential to the life of RO membranes. It is not an exaggeration to state that chlorine will damage an RO membrane.

: No Compromises

save money and/or space, some users may be tempted to skip the carbon or the sediment removal pretreatment steps when considering a reverse osmosis system for home use. Both steps are not only critical to the process of producing clean water but are also imperative to preserving the life and investment made in the RO membranes.
