Water Filters Vs. Water Softeners – Which Do You Need?

Monday, February 28th, 2011

Depending on where you live, your drinking water may need some type of filtration, but which is right for you? Do you need a water filter or a water softener? What if you need both? How do you know which one is right for you?

Well, to answer these questions, let’s take a look at what water filters and water softeners do, then you can decide on the best solution for you and your family’s water filtration needs:

Water Softeners

So, what exactly does a water softener do and why do you need it? Well, simply, they soften hard water. Hard water is full of minerals and deposits such as calcium and magnesium. Although no harm will come to you from hard water, it’s nightmare for cleaning showers, tubs and causes problems for pipes and plumbing fixtures.

By using a water softener, you will break down the hardness or materials in the water. Different softeners use different methods including: ion, electrical and magnetics. It’s best to get your water tested to find out for sure, if you have hard water. Then decide on what method works best for you.

Water Filters

Without purifying our drinking water, you could consume things that contribute to disease and illness. To prevent this, most water treatment facilities employ chemicals such as chlorine to treat the water. This, however, introduces new problems for us. I mean, you would you want to drink something that resembles the water in a swimming pool? I didn’t think so. So counter this, there’s water filters.

Basically, water filters take out all the bad things in your water like the chlorine and other chemicals – leaving you with clean tasting and smelling drinking water. The most common filter is a carbon-based filter – it can remove the majority of chemicals in your water.

What’s Best For Your Water?

For many a water filter is all they will ever need. For others, a water softener plus water filter is a requirement. Remember how we said to test your water? Well, if you find out you have hard water, it’s best to get yourself a combination filter and softener to clean out the impurities in your drinking water. Otherwise, stick with a single water filter for your water purification needs.

Revolutionary Personal Water Filtration

Monday, November 29th, 2010

Over 1.2 billion people around the globe don’t have access to potable water. Many of them live in the continent of Africa. So it should come as no surprise that a solution to this problem might come from an inventor who lives there.

Meet Dr. Eugene Cloete. A microbiologist by training, Cloete is currently the Dean of Natural Sciences at the University of Stellenbosch, just outside Cape Town, South Africa. In addition to his teaching ability, Dr. Cloete apparently has a knack for invention. With nine patents to his name, the first of which he earned at the age of 23, Eugene has adopted a way of thinking different than that of most peoples’. “[creativity is] like reading and writing,” said Cloete, “the more you use it, the better you get.”

With much of South Africa’s tap water riddled with disease-causing bacteria, heavy metals, and pesticide residue, something needed to be done. In short, Dr. Cloete has invented a disposable filter, which looks very similar to a tea bag, to filter water as it is poured from a bottle. Each filter is capable of ridding bacteria, heavy metals, and harmful chemicals from about 15 liters of water before it needs to be thrown away.

Cloete, an expert on inhibiting growth of bacterial slime, says he came up with the idea while on a faculty tour of his current department. He happened to notice a tea bag sitting on the break room counter when he started to explore the idea. It wasn’t until he watched a presentation at the university during which a student demonstrated how to spin nanofibers – filaments finer than human hair – that he figured out how to do it. He combined this technology with both that of the anti-bacterial membranes he had already been working on, and the traditional water filtration component activated carbon to yield the filter.

Since announcing the invention in July, Dr. Cloete and his team of two post-doctoral colleges have received hundreds of inquiries from excited philanthropists, aid organizations, and retailers. This little tea bag is sure to save lives.

Seawater/Brackish Water Reverse Osmosis

Monday, August 9th, 2010

Reverse Osmosis, also known as hyper filtration, is the preferred method of seawater and brackish water purification. As the equipment needed to perform reverse osmosis is cost-effective, and the process requires little input energy compared to other methods of purification, reverse osmosis has become the worldwide leader among desalinization methods. Developed at UCLA, and used commercially since the 1970’s, seawater reverse osmosis has served marine professionals for nearly 40 years.

Seawater Reverse Osmosis (SWRO) is used in a wide range of commercial applications. Marine professionals such as commercial fisherman and offshore rig workers rely on SWRO to provide freshwater for routine daily tasks such as bathing, cleaning and of course, drinking.

In larger applications, such as cruise ships, SWRO is sometimes also used. In such applications, it is necessary not only to desalinize water, but to provide quality freshwater. Cruise liner restaurant professionals count on SWRO for water used for cooking, as well as making coffee, soda and other beverages. Here, consistency is key. By way of its simple yet effective design, reverse osmosis is able to consistently satisfy the needs of those who count on it.

The process itself is relatively simple and straightforward. In order to purify a liquid, the “solvent” (in this case, water) is put under pressure in excess of 250 psi for brackish water and 1000 psi for seawater, forcing it through a semi-permeable membrane. This application-specific membrane allows water molecules to pass through, but catches “solutes,” yielding purified water. When employed, reverse osmosis is capable of not only of de-salting water, but also removing other impurities such as bacteria, ions and particulates.

Realizing the Benefits of UV Sterilization

Wednesday, July 14th, 2010

Ultraviolet water sterilization is a process by which the threat of microorganisms and other biological contaminants, which are present in municipal water supplies and private sources (like wells), can be effectively nullified through exposure to a specialized ultraviolet bulb.

How does it work?

Sterilization systems which employ ultraviolet radiation operate on a few simple principles. First, a UV source, which is usually as simple as a specialized light bulb, is placed inside a reflective quartz sleeve. This sleeve is placed over a flow chamber which exposes all water passing through the system to a unique, specially determined germicidal wavelength of 254 nanometers.
