When to Change Membranes in your Reverse Osmosis Water System

Posted on by

The technology of reverse osmosis water systems is ever expanding but we mustn’t forget that for any equipment to function efficiently and for as long a time as possible, we need to maintain it.
On the surface, when to change the membrane of a reverse osmosis water system might seem obvious and most companies make it simple by relying on the following three guidelines:

The three year cut off (manufacturers usually put this time period as their warranty). An increase in the RO (reverse osmosis) permeate conductivity, related to water quality requirement. Designated reduction in permeate or product flow rate when related to water demand.

However, there is more to it than first meets the eye and the reliance on simple parameters can actually be counterproductive and lead to premature membrane replacement. So, what should you look at?

Is Age Important

RO membranes can last up to ten years and still be functioning with the utmost efficiency. Age associated performance deterioration occurs very slowly and it is much more likely that a replacement is needed for an entirely different reason than age, one most often related to how well the reverse osmosis water system is maintained.

Oxidant Exposure

Free chlorine is a strong oxidant that can have a huge negative impact on membrane life. The extent of damage will correlate with the chlorine concentration and the amount of time the chlorine has been in contact with the element. Any contact, however, causes issues and can lead to the need to prematurely take membrane replacement action.

Salt Rejection

Decline in salt rejection can vary, but if you decide that the decline is unacceptable when occurring in sync with an increase in normal permeate flow, you will need to consider replacing the membrane elements in their entirety. Before you do, however, you need to gain a little more knowledge about the problem. Measure the conductivity of the permeate water from each membrane vessel, for example, and you will be able to determine exactly which element needs changing and the exact location of that element. A complete replacement may not be necessary.

Fouling

The primary cause of membrane deterioration is fouling, which is succinctly defined as the increase in RO feed-to-concentrate pressure drop of more than 15% (or the permeate flow declining more than 15%). Particles collecting and impacting on the surface of the element make the job of cleaning solutions much tougher, and in some cases impossible. More aggressive cleaning can be attempted effectively, but if it is unsuccessful membranes will need to be replaced.

Scale

The formation of scale can be a problem for a few reasons. Onsite cleaning is normally effective in solving this issue with no membrane replacement necessary, but if the scale is caused by sulfate you may end up having to go for a replacement of the concentrate-end membranes.

When you know why your reverse osmosis water system is not performing as it should, you can begin to discern whether or not you need to replace the membrane in its entirety or just a certain element. Understanding the causes of a problem and the potential extent of it might save you unnecessary time and money in getting it fixed.

Make Money With Black And White Digital Photography

Posted on by

Black and white photography has long been a staple product of the art world. There is something about capturing the world around us and rendering it, and the people in it, in such a stark medium as black and white. In a way, this type of art takes away any preconceptions one might have about the given subject and allows the viewer to see the content as it really is, and even add their own ideas.It’s important to note that black and white photography was the beginning of photography and holds a special place in many photographers’ hearts. This is one of the reasons why it has become a bit of a trendy thing to do nowadays. Basically beginner photographers are starting to take up black and white photography more often than normal photography. Why? Mainly because they are still able to use the most advanced, up to date cameras while creating amazing black and white photos.The latest camera models have settings for black and white photography and some photo editing software enables photographers to change color photographs into black and white. Any of these methods can be used to achieve the classic black and white look that can impress any viewer.The scope of black and white digital photography is not only about portraits and landscapes. There are thousand and one things that you can express with black and white photographs. So the next time you have the digital camera in hand, focus on abstract shoots. Treat black and white digital photography, as a mode to portray the world in a different light and you will never be short on potential photography subjects.To start with your own black and white digital photography shots, you will not need extra effort and complications other than shooting as is. Take the shot in color then you can switch the setting of the digital image in an editor, using array of choices. If you are using Photoshop or Fireworks, you can change the whole image into black and white by editing “Hue and Saturation” or simply switching it to “grayscale” format.Since black and white digital photography doesn’t rely on color to tell the story, the contrast of shades will need to be relied upon. This is one of the most important black and white shooting tips to learn. It is important to make sure subjects stand out even more so in black and white than in color. While a dark blue shirt might look awesome against a dark green setting in color, it will likely get lost in the shuffle in black and white.While that dark shirt and dark background can present problems in contrast, lighting can help fix the issue. The best way to master lighting for this type of digital photography is to play around and be willing to experiment to see what works and what doesn’t. Try using the black and white settings in all kinds of situations to really master what needs to be done under different circumstances to effectively light up a shot.Why not make money from your digital photography and get paid to submit your photos to the internet or start up your own photography business.Remember a black and white picture of a single flower can be breathtaking.
