CULTURAL QA 08-2023-9A Q1 How good is RO water for everydayconsumption?
A1 BK Sapan, B.Tech ,MBA from RajivGandhi Proudyogiki Vishwavidyalaya, Bhopal (Graduated 2003)Feb 28 Reverse Osmosis (RO) water is generally considered safefor everyday consumption. Infact, many people prefer RO water for drinking and cooking because it removesimpurities and contaminants that may be present in tap water, such as bacteria,viruses, dissolved salts, and heavy metals. RO water is produced by forcing water through asemi-permeable membrane, which traps contaminants and allows only pure water topass through. The resulting water is free frommost impurities, but it may also lack some essential minerals that are presentin natural water sources. This is because the membrane used in the RO process can filter outminerals as well as contaminants. While consuming ROwater is generally considered safe and healthy, it is important to note that itmay not be the best source of essential minerals like calcium and magnesium. If you are concerned about mineralintake, you may want to consider drinking mineral water or adding mineralsupplements to your diet. Overall, RO water is a safe and convenient option foreveryday consumption. However, it is always a good ideato ensure that the water you are drinking is of good quality and has beenproperly filtered and treated to remove any potential contaminants. Q2 Is RO water better than commerciallyavailable water cans or bottled water like Aquafina? A2 Venkateswara Swamy Swarna,FormerScientist, Metallurgist, Quality / NDT Manager at Department of Atomic Energy,India (1967–2008)1y Aquafina and other leading brands of bottled water arealso made using RO and other state of the art water purification technologiesand some minerals are added to maintain the taste. Domestic RO units also have taste maker modules in somemodels. Whether to investin a domestic RO water purifier (with its initial cost and annual servicecosts) or whether to buy Aquafina / other leading brands of water - depends onyour personal preference. Some people preferto buy 20 liter refills and others prefer to buy half liter, one liter or twoliter bottles… All the options aresafe health wise but vary in their economics (cost per liter). Also, somepeople are against the plastic bottles though most of them are recycled. My note- I have ROSystem installed as well as we purchasebarrel water. RO water is used for cooking and drinking and barrel water forother uses like washing rice etc. Interesting reason for purchasing barrel water- When there is veryless water in bore-well and Muncipalsupply become irregular, RO cannot be operated more because of waste water. Further when RO system fails, barrel water will be readily available,since we regularly purchase. Q3 Should you add anything to your septictank? A3 David Thomas, Professional Engineer,Civil, Alaska1y Nope. There are plenty of bacteria in what you send into the septic tank andthey’ve been growing and developing into strains that like your groundtemperatures and wastewater stream for many year now. If you have a lot of people in the house, use yourgarbage disposal a lot and have a poor septic tank installation that allows itto get cold every winter, you’ll need to get it pumped out every few years toremove the solids. If there are fewer users, you don’t use your GD towash large quantities of food waste down the drain and your septic is warm(because it’s deep and/or close to the house and/or you live in the south) thenit’ll only need to be pumpedout every 10–20 years. Don’t pour large quantities of toxic chemicals downthe drain - no gallon jugs of bleach. Normal quantities of household chemicals,diluted into a bucket of mopping water or a load of laundry and by the week’sother water uses are fine. Your septic tank doesn’t need RID-X, your engineoil doesn’t need STP, and your refrigerator doesn’t need a box of baking soda,even though you’ll increase the sales for those companies, if you obey theiradvertising. My note- Flushing with more water willavoid blocking. Septic tank become full earlier should not be in the mindbecause, removing block is three times costlier than septic tank cleaning. Q4 For a British person who has traveledto the United States, which technological advances impressed you the most? A4 Jaydee, Lives in The United Kingdom(1954–present)22h Contactless payment; e-booths at immigration;restaurants which tell you what you owe, the total including service; shopswhich tell you what you are expected to pay, not add on extras when you get tothe till. Hang on a mo, that was before we left the UK, Sorry US, youdeed to catch up. Q5 Why is 120/80 considered normal bloodpressure? What's the logic behind 120 and 80? Is that value normal at any age,or does "normal" change? A5 HealthyMen, Men’s Health specialistJul 27 The values 120/80 mmHg are considered normal blood pressurebased on standard medical guidelines, and they represent the pressure exertedon the blood vessels during the cardiac cycle. The two numbers ina blood pressure reading have specific meanings: 1. Systolic Pressure (120): The top number, alsoknown as systolic pressure, represents the pressure in the arteries when the heart contracts and pumpsblood out into the circulation. 2. Diastolic Pressure (80): The bottom number,diastolic pressure, indicates the pressure in the arteries when the heart is at rest between beats. The reason why120/80 mmHg is considered normal is that it reflects a healthy balance of bloodpressure in the arteries, indicating that the heart iseffectively pumping blood while also allowing the vessels to relax and fillwith blood during its resting phase. These values indicate that the cardiovascular system isfunctioning optimally. It's importantto note that "normal" blood pressure can vary slightly depending onfactors such as age, gender, and individual health conditions. Bloodpressure tends to naturally increase with age, and what is considered normalfor a young adult might be slightly higher for an older adult. Therefore, blood pressure ranges are often categorized intodifferent stages, such as normal, elevated, stage 1 hypertension, and stage 2hypertension, allowing healthcare professionals to assess and manage blood pressure levelsappropriately. Regular bloodpressure check-ups are essential to monitor changes over time and detect anypotential issues early. If blood pressure consistentlyfalls outside the normal range, medical attention and lifestyle adjustments maybe necessary to prevent complications and maintain cardiovascular health. As always, it's best to consultwith a healthcare professional to understand your specific blood pressure goalsand any necessary interventions. Q6 What are the pros and cons ofinstalling a whole house water filter or a reverse osmosis system at home? Robert Durtschi, Workingas Plumber for a Time with a at Independent Master Plumber (2009–present)11mo Pro: your whole house is filtered. Con: yourwhole house is filtered because of that you will need to supply replacementfilters more often. The filter I useresides next to the kitchen sink. Which is where you need it 99% of the time. Ifound it by looking at many many reviews looking at the cost per gallon and howsoon the filter needs to be replaced. It took no tools to install I built aplatform to put it on so I could fit taller containers such as gallon jugsunder it. We had used it for 5 years and we are considering replacing it justnow. You may not last that long, we are empty nesters! Although my wife was using it towater her plants but I finally Persuaded her to use rain water instead. Iwas have posted the contact information on it recently. We had installed awhole house filter back in Utah when I was working in San Jose, California andmy wife was living in Utah. (Thank heaven for free cell to cell minutes!) My note-Most plants grow well with rain water or natural water than with filtered water.Of course you get filteredwater in wash basins, in wash rooms etc. For water heaters it is good, for bathit is good, but for toilet uses and septic tank function normal water isbetter. Q7 What are some British phrases thatAmericans don't understand? A7 David D’Angelo,Father of One(2020–present)Aug 2 Fanny. When I’m pissedyou’ll probably think it’s because of my boss, wife, or political system, butit’s because of all the alcohol. When I talk aboutmy bum I mean my backside, not my personal homeless guy. If I say somethingis rubbish, I want you to throw it away. I’m not saying it sucks. When I say I reallyneed to use your loo, please don’t stare at me blankly. It means I really needto pee, and preferably not in your pot plant. In the UK apavement is what you walk on, not a 90s Indi Rock band. We have chips withfish.Biscuits are cookies.Men wear jumpers.We also wear really short pants. I should probablysay bloke, but you’ll be lost with that one. Oh, and football isa game we play with our feet, not with our hands. As confusing as that sounds. All the above QA are from Quora website on 09-08- 2023.
