Tips Nak Maintain Badan!!!

Tahu tak!!???

Tahukah anda mengamal minum secawan air teh "O" setiap pagi boleh
mengawal berat badan anda. Isyaallah jika anda mengamalkannya, berat
badan anda akan berkurangan. (memang terbukti keberkesanan) .

Al-Quran Juga ada mengajar kita menjaga kesihatan spt membuat amalan
spt:-

1. Mandi Pagi sebelum subuh @ sekurang kurangnya sejam sebelum matahari
naik. Air sejuk yang meresap kedalam badan boleh mengurangkan lemak
mengumpul. Kita boleh saksikan orang mengamal mandi pagi kebanyakan
badan tak gemuk.

2. Rasulullah mengamalkan minum segelas air sejuk setiap pagi.
Mujarabnya Insayallah jauh dari penyakit (susah nak kena sakit).

3. waktu sembahyang subuh disunatkan kita bertafakur ( iaitu sujud
sekurang kurangnya seminit selepas membaca doa). Ia boleh mengelak dari
sakit pening atau migrin. Ini terbukti oleh para saintis yang membuat
kajian kenapa dalam sehari perlu kita sujud. Ahli-ahli sains telah
menemui beberapa milimeter ruang udara dalam saluran darah di kepala yg
tidak dipenuhi darah. dengan bersujud maka darah akan mengalir ke ruang
berkenaan.

4. dalam kitab juga ada melarang kita makan makanan darat bercampur
dengan makanan laut. Nabi pernah menegah kita makan ikan bersama susu,
di khuatiri akan cepat mendapat penyakit. Ini terbukti oleh saintis yang
menjumpai di mana dalam badan ayam mengandungi ion (+) manakala dalam
ikan mengandungi ion (-). jika dalam suapan ayam bercampur dengan ikan
maka terjadi tidakkan balas biokimia yang terhasil yang boleh merosakkan
usus kita.

5. Nabi juga mengajar kita makan dengan tangan dan bila habis hendaklah
menjilat jari. Begitu juga ahli saintis telah menjumpa bahawa enzime
banyak terkandung di celah jari jari, iaitu 10 kali ganda terdapat
dalam
air liur. (enzime sejenis alat percerna makanan, tanpanya makanan tidak
hadam)

Wassalam...

Sabda nabi Ilmu itu milik tuhan, barang siapa menyebarkan ilmu demi
kebaikkan insyaallah tuhan akan mengandakan 10 kali kepadanya.

Wallahu'alam

Reverse Osmosis Water Treatment

What is Reverse Osmosis?

Reverse osmosis (R/O) is a water treatment process in which water is forced through a semi-permeable membrane that has very small holes or "pores". Clean water passes through and impurities that are too big to pass through the membrane are left behind and flushed away.

Do I Need a Reverse Osmosis Unit?

It is presumed in this document that the water you are using meets all health regulations and is known to be safe. If your municipality or utility supplies your drinking water, it is likely that you do not need a reverse osmosis unit. Municipally supplied drinking water is microbiologically safe. It is treated to meet health and aesthetic requirements, and is subject to routine testing for microbiological contamination.
If you obtain drinking water from a private supply such as well, it may not be safe from microbiological, chemical, or other types of contamination. Drinking water from private sources should be tested periodically to determine if treatment is required; and, if so, for what specific contaminants or minerals.

Water chemistry is complex and no single water treatment device can be used to remove all types of substances from water. Different drinking water treatment devices have their own advantages and disadvantages. Each household must individually determine if there is a need for additional water treatment. If this is the case, determine the unit or combination of units best suited for your water needs.

How Does Reverse Osmosis Work?

Reverse osmosis systems purify water by forcing pressurized water through a very fine, plastic membrane. If the raw water being treated comes from a well or another private source, disinfection and pre-filters (to remove chlorine and/or particulates/sediment) may be needed in advance of the R/O unit to remove contaminants that can foul or damage the membrane.

Stages of reverse osmosis:

1. During the initial filtration stage, tap water or well water (pressurized by a booster pump) is passed through a particle filter (a pre-filter) that removes silt, sediment, sand, and clay particles that might clog the R/O membrane.

2. The water is then forced through an activated carbon filter that traps minerals and contaminants such as chromium, mercury, copper, chloramine and pesticides. It also removes chlorine, which is important, as chlorine will shorten the life of the membrane.

3. Water is transferred under pressure into the R/O module, allowing only clean water to pass through the small pores in the membrane. Impurities unable to pass through the membrane are left behind and flushed down the drain.

4. Treated water is then sent to a storage tank.

5. Treated water is passed through an activated carbon filter before use to further improve the water's taste and smell.

Water that contains manganese, hydrogen sulphide or iron should be pre-treated to extend the life of the membrane. A dealer can recommend the pre-treatment needed.

Note: Reverse Osmosis units produce no noise other than the sound of water discharging into the drain (usually a sink or a floor drain).

How Do I Know What Size Unit to Buy?

R/O units are rated according to the amount of treated water produced per day. For example, one type of unit produces 50 litres of treated water per day under its design conditions. Such a unit is generally rated with 60 psi water line pressure, a water temperature of 25° C (77° F), normal dissolved solids and 2 atmospheres of pressure. In reality, conditions frequently vary. Line pressure is often lower, water will frequently be colder than 25° C and backpressure in the storage tank will likely reduce the performance of the unit. Consequently, you should examine water conditions and buy a larger rated unit than needed if any of the above problems are noted.

Where Do I Buy Reverse Osmosis Units?

Reverse osmosis units are sold at some department and hardware stores, and by water equipment dealers. Companies can be found listed under "Water"or "Water Companies" in the Yellow Pages. You may wish to talk to a variety of vendors to compare features.

How Much Do Reverse Osmosis Units Cost?

Reverse osmosis unit prices vary, from $400 for a portable or undersink unit to $2,500 for a larger, stationary (basement) unit where a booster pump and a pressure system are installed. Replacement pre-filters range in price from approximately $100 – $200 each.

Who Installs the RO Unit?

Many R/O units are designed to operate on the kitchen counter. Some of the larger units are connected under the counter or in the basement. The unit will need to be hooked up to the water line and a discharge-to-the-drain line. Larger units may require professional installation, where a special water supply line is run from the main household water line. If you are unsure about installation, contact a plumber or mechanical contractor.

What Are the Benefits of Reverse Osmosis?

Reverse osmosis can remove dissolved solids, salts, minerals that cause hardness, organic chemicals and other impurities. It can improve the taste of water for people who do not like the taste of dissolved mineral solids.

Treated water will not produce scale in kettles and coffee makers. Because sodium and potassium are removed, people on a medically prescribed sodium- or potassium-restricted diet may benefit. R/O units may also remove contaminants such as chromium, mercury and nitrates. Before purchasing a R/O unit, check the certification and literature for the particular model to verify exactly what it can and cannot remove.

Is Reverse Osmosis - Treated Water Safe to Drink?

Reverse osmosis treatment systems remove minerals like calcium and magnesium from drinking water. In Canada, water is a minor source of such minerals when compared to foods. If you consume a reasonably balanced diet, you do not need to take a mineral supplement when drinking water treated with a reverse osmosis system. Low levels of minerals in drinking water may be a concern for people living in countries with very hot climates.

Is the Water Source Safe?

A R/O unit should be used only with drinking water that is known to be safe to drink. Although reverse osmosis can remove microbiological contaminants, R/O does not disinfect the water to drinking standards. A flaw or tear to the membrane could allow untreated water to flow through the unit without removing disease-causing organisms. Remember if you are unsure of the quality of your water, get it tested. If you have any doubts about the safety of your water, then it should be disinfected before using a R/O unit.

How Much Water Does the Unit Use? Is It Water-Efficient?

Some R/O units can produce 4 litres per minute and others will produce 30 to 94 litres per day. In operating a R/O unit, a large amount of incoming water is used to produce the final treated water. This unusable water (called brine) contains contaminants that the R/O unit has removed. The amount of brine created will depend on the quality of the incoming water.

Operating a reverse osmosis unit is not water-efficient — and the amount of water used depends on the quality of the incoming water. In some cases, where water is free of dissolved solids, two litres of water may be needed to produce one litre of finished water. In other cases, 4 or 5 litres of water may be used to produce one litre of treated water.

A family of four might need 40 to 80 litres of water to produce 8 to 16 litres of treated water for drinking and cooking per day. This would cost about ten to twenty cents per day for water. If more treated water is desired, then more water would be used. This will also increase water and wastewater bills, or create a higher demand on your well and septic system.

Watch the Water Pressure

R/O units will not operate efficiently at water pressures below 40 – 45 psi. If the pressure is too low, as in the case in many rural private systems; in an apartment on a higher floor of a building; or at the end of a long water line serving several units, a booster pump should be installed to increase pressure.

Do I Need to Maintain the Unit?

Reverse osmosis units must be maintained as per the manufacturer's recommendations. Typically the sediment pre-filter and the activated carbon pre-filters should be changed at least annually. However, these prefilters may need to be changed as often as once every six months if the water entering the unit contains sand, large amounts of chlorine or other substances that impair filter efficiency. Although membranes in a well-maintained unit can last for several years, the membrane may need to be replaced more frequently than the manufacturers suggested timeline.
