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.

How to Find the Right Health and Fitness Membership For You

Posted on by

Gyms and centers frequently run specials on their health and fitness membership fees. The timing will vary, but many offer great deals after the first of the year, when many people are making resolutions regarding weight loss or improving health. If possible, choose a time when the gym you want to join is offering an attractive health and membership fee special.Typically, a health and fitness membership term is for one year, although some ask for three year commitments. Try to get a one day pass or trial health and fitness membership before you sign a long term contract. This will allow you to actually work out at the gym and at the time of day you will normally visit so you can see for yourself that you will be able to have access to the machines or classes you want.A trial health and fitness membership will also allow you to test your commitment to going to the gym. Some people become enthused with the idea and sign a contract, then find they just can’t work it into their schedule or that the gym is too crowded at the time they need to go.Verify what amenities are covered under your health and fitness membership. For example, if you need to bring the children, is supervised care free or must you pay an extra fee? Does your membership cover all of the classes offered, or is there an additional charge if you wish to take, for example, a yoga class?Many gyms offer personal trainers who will work with you on an individual basis and develop a nutrition and exercise program tailored to your needs. However, these are normally not included in your basic health and fitness membership. Rates are usually less than engaging a trainer on your own, though.Be sure and get all the fees involved with joining the gym, and not just the membership fee. For example, is there an initiation or registration fee that you must pay in addition to dues? Few gyms tack on laundry fees to cover towels, but a handful will. Don’t hesitate to ask what other fees will be involved.If you are not sure whether you will like working out at a gym, see if you can find one that offers a month to month health and fitness membership. You may have to pay a registration fee and then of course your monthly dues, but you do not have a long term commitment that you must continue to pay or suffer a potential blotch on your credit report.Don’t sign a health and fitness membership contract with the first gym you visit. Finding a place to work out is a very personal choice. Take the time to check several before you commit to a health and fitness membership so that you can find the best gym for your needs.Read your health and fitness membership contract carefully to make sure it accurately reflects what you have been told verbally. If the contract makes no mention of free classes but you were told there was no additional charge for them, ask why they are excluded. Or if you were told the term was 18 months and the contract states 36, object. If you cannot get the health and fitness membership contract to reflect what you are expecting, do not sign it. Your contract is a legal credit commitment, and you will have little choice except to pay off.
