Comparisons of Ultra Filtration and Reverse Osmosis

Drinking CowayWhat is Reverse Osmosis? Reverse osmosis, also known as hyper filtration, is a membrane filtration technology in which water is forced by pressure through a semi-permeable membrane allowing the water to pass through while rejecting the larger contaminants (think of a strainer catching peas but allowing the water to pass through). In this regard, reverse osmosis is similar to micro filtration and ultra filtration.  However, reverse osmosis differs from these two technologies in that with micro filtration and ultra filtration the water is forced straight through a semi-permeable membrane which traps the larger contaminants. 

Reverse osmosis systems are T shaped forcing some of the water straight through the top of the ‘T’ and through the membrane while the rest of the water is swept down the base of the ‘T’ to clean the contaminants off of the membrane.  This process keeps the membrane clean and free of contaminants. 

Because of this, reverse osmosis systems have a holding tank for the purified water while the excess water goes down the drain in the system.  As a result, typical reverse osmosis systems waste four gallons of water for every one gallon of purified water.

Ultra filtration is membrane technology without all the wasted water. The main differences between the two methods is that reverse osmosis membrane pores are usually a little smaller, ultra filtration does not require as much pressure as RO and the water is purified as it is used with ultra filtration rather than being purified hours or days before it is used with RO systems.

Reverse osmosis systems must use storage tanks to hold the water before use. For counter top RO systems and most larger permanently installed units, the storage tanks are maintained at atmospheric pressure. Where as water is added to the tank, the air charge is compressed and the pressure in the tank rises. The elevated pressure then moves the drinking water from the storage tank to the faucet.  This storage tank system can cause a drop in the water production rate due to the fact that the accumulated pressure in the storage tank acts as backpressure on the membrane so when the tank pressure increases, the differential pressure across the membrane decreases.

Another draw back of Reverse Osmosis can be servicing the system. Like all water treatment units, the quality of water produced by a reverse osmosis system will be directly affected by the frequency of the systems service. If a reverse osmosis system is left unattended, their can be total failure of the system which will result in contamination of the water. Most reverse osmosis systems on the market today do not come with any type of monitoring devices to tell you when your system needs to be serviced.

How to Choose Your Wedding Caterer

A wedding can be a very exciting time in anyone’s life. However, weddings can also be stressful, especially during the planning process. Many want their wedding to be absolutely perfect, and lament over each choice they must make for the event, from the dress, to the DJ. However, if you are looking for the right catering company, there are a few simple steps you can take to make sure you are getting the best. Here are our tips about what to look for in any wedding catering companies:

Great Service

Your wedding caterers (or any you are considering) should offer you the upmost in service. You are, after all, the customer. Just so you know what kind of service to expect, meet with your caterer several times before the actual wedding. Ask them about what services they will or will not provide. You will also want to ask friends and family members for recommendations about catering services that go above and beyond for their customers.

Great Food

Great food is, of course, very important. You want your food to stand out above the rest. In order to do this, ask your caterer if they have a specialty, or a dish they are very good at. If they say yes, put it on the menu. If not, ask they for a tasting session of a variety of meals, appetizers, drinks, or other dishes they would like to provide for your wedding. Most professional services are more than happy to do this for prospective customers. In order to check on presentation, ask to see weddings they have done previously in the past (most services will have photos, or will have photos posted online, or on their social media pages). Then, pick something that you find both intriguing, as well as memorable.

Right Prices

Finally, you want to be sure that the price you spend for your wedding catering services is right. Normally, catering services are willing to help you work within a budget. Simply ask them! However, if your caterer seems unwilling to work with you on your budget, chances are, you may want to find a new caterer. Or, if their prices seem outrageous, even if their food is divine, you may also consider another business to do the job. Check with a few catering services in the local area to estimate what you think a good price would be for the number of people you want to have at your wedding.

Willingness to Work with You

You will want to book your caterer much earlier than your wedding (about 9 months since they are in such high demand). But after that decision has been made, you want to know that the wedding catering service will work with you. Ask your venue for recommendations about catering services. Sometimes, they will have great tips about who has worked with them most willingly in the past, or may have a list of preferred catering services in the area.
