Ultima is the number one water purifier brand in Bangladesh. Ultima ensures 100% safe and pure water by implementing USA-technology reverse osmosis (RO) water treatment. Ultima never uses a gravity system, ultrafiltration (UF) alone, ultraviolet (UV) alone, or mixed harmful germ-killing chemicals. But Ultima uses the world’s most advanced Reverse Osmosis system, including ultrafiltration and ultraviolet, to ensure 100% safe & balanced water when necessary. Ultima provides the best quality RO water purifier at a reasonable price.

If you want to set up a Reverse Osmosis Water Purifier in your home or business, you need to understand how the Ultima RO water purifier works. ULTIMA RO is the most advanced and latest USA technology-based automatic inline system that will be connected directly to your water supply and give you 100% safe & balanced water made at home! So there is no hassle of boiling water and no risk of chemical mixing. Its 100 GPD purification capacity ensures 100% safe, pure & re-mineralized alkaline water through 6 advanced purification stages (MF + CF + UF + RO + Mineral &Alkaline Cartridge + Post Carbon Filter). Additional pre-treatments like Iron Reducer, Water Softener, etc. (up to 3 extra stages) may be required based on your water quality test report. 

ULTIMA Water Advisor will recommend the appropriate water treatment after testing your supply-water. 

Let’s see deeply in six stages how the RO system work-

Stage 1: MF Filtration:

MF filteration removes fine and coarse particulate impurities and dirt. In Bangladesh, only UlLTIMA is using the Best Quality PP (Polypropylene) filter with 100% food-grade and smallest pore size. Ultima 0.45 micron PP (Polypropylene) filters are about ten times smaller than 5.0-micron pore sizes available in the market. As a result, a large number of harmful germs are blocked at the very initial stage. 

Polypropylene (PP) filter is a type of perforated filter made from thermoplastic. This is also known as a sediment filter. It is usually used as the first stage of RO Water Purifier. This stage is mainly used to remove insoluble particles (soil, sand, fiber, organic waste, etc.) from the water.

The effectiveness of the PP filter depends on the fineness of its pores. More fine-grained PP can prevent large amounts of waste; So the value of PP is determined based on the shape of the hole. PP with delicate pores usually weighs more.

PP with 5 “, 6”, 8 “and 10” lengths are available in the market for home use. The pores of the PPs in the market are up to 0.45, 1, 5, and 10 microns in size. Weights are up to 70, 80, 100, 120, and 150 grams.

Of these, the 10 “tall PP E weighing 150 grams with 0.45-micron perforation for home use is the best in Bangladesh.

► ULTIMA RO water Purifier has 10 inches 0.45 micron, 150 g PP Filter. It is readily available and affordable, as it is regular market size.

► The service life of the RO Membrane of a RO water Purifier is increased through a good quality PP. 

Stage 2: CF Filtration:

I-1100 grade Granular Activated Coconut Shell Carbon filter, commonly known as GAC filter, removes chlorine and organic impurities like harmful pesticides absorbing the bad odor.

It’s a matter of pride that ULTIMA never uses the low-cost Coal Carbon available in the market.

Activated carbon is prepared by applying heat to the coconut shell or coal in an oxygen-free state. The number of Iodine is the measure of the effectiveness of activated carbon. The amount of Iodine that can be absorbed per 1 gram of carbon is called the iodine number. The issues of purity, absorption capacity, working circumference, porosity, etc., are expressed together with the number of Iodine.

Granular Activated Carbon (GAC) is granular carbon. The gaseous material and odor of water are removed through this stage. GACs with different iodine numbers are available in the market. For example, Iodine – 300, Iodine – 800, Iodine – 1100, Iodine – 1200 best Advanced Activated Carbon is Iodine – 1100 and Iodine – 1200 

►ULTIMA RO water purifier contains Iodine – 1100 grade GAC

Stage-3: UF Filtration:

UF Filteration also uses an I-1100 grade Compressed Activated Coconut Shell Carbon (CTO) filter that removes the remaining impurities and foul odor. CTO Chlorine (Absorbed) Taste and The odor is a perforated screen made of activated carbon. Activated carbon is prepared by applying heat to the coconut shell in an oxygen-free state. CTO filters manufactured by Coal Carbon are commonly available in the market, which discourages water experts from using and encourages coconut cell carbon use. Iodine content is a measure of the absorption efficiency of activated carbon. The amount of Iodine that can be absorbed per 1 gram of carbon is called the iodine number. The issues of purity, absorption capacity, working circumference, porosity, etc., are expressed together with the number of Iodine. Negative ions and odors in water are removed through this stage.

CTOs with different iodine numbers are available in the market. For example: Iodine – 300, Iodine – 800, Iodine – 1100, Iodine – 1200

► High-quality CTOs are Iodine – 1100 and Iodine – 1200

► ULTIMA RO water purifier contains Iodine – 1100 grade CTO

Stage-4: RO water purifier Filtration:

ULTIMA uses the best quality Cellulose filter, RO Membrane, with 0.0001-micron pore sizes that remove dissolved salts, hardness, and heavy metals like Arsenic, Cadmium, Chromium, Lead, Mercury, and Ferrocyanide. It also removes Viruses, Bacteria, and Algal is ensuring 100% safe and pure water. At this stage, water molecules pass through a 0.0001 micron RO membrane with ULTIMA’s 100 GPD Booster pump, which is two times more powerful and long-lasting than the 50 GPD RO purifier commonly available in the market. 

The RO Membrane is a fine perforated semi permeable screen that is the RO water purifier’s main component. The size of the pores of the correct quality RO membrane is 0.0001 micron. Water flows through the screen by applying firm pressure on the RO membrane with a booster pump. Since the hole size in the screen is 0.0001 micron, all the substances and ions larger than the hole are stuck.

Tests have shown that all fatty substances and 98-98% ions are trapped in the Filmtech/ Vontron-RO membrane; Only 2-3% of valence ions (sodium and potassium) are present in water, which is not harmful to the human body.

The RO water purifier’s efficiency depends on the correct quality (0.0001 microns perforated) RO membrane. The better the RO membrane of an RO water purifier, the more influential the RO water purifier.

The booster pump and RO membrane of any RO water purifier should have equal capacity. This is because if the ability of the booster pump exceeds the power of the RO membrane, the dissolved ions can pass through the membrane as a result of the extra pressure; Similarly, if the capacity of the booster pump is less than the power of the RO membrane, sufficient water cannot be obtained through the membrane as per the demand due to low pressure.

Therefore, customization of ISO 9001: 2008 certified RO Filtration technology recognized by NSF, ANSI, and EPA of the USA is not supported.

How much water will be filtered in the allotted time through the RO water purifier depends on the RO membrane’s capacity. So RO water purifier with high capacity RO membrane and equal capacity Booster pump is more effective. There are different capacities and brands of the RO membrane in the market. For example: for household use, there are 50 GPD, 75 GPD, and 100 GPD, etc.

ULTIMA RO water purifier (Domestic) has 100 GPD capable RO membranes. 

Stage -5: TDS Modulator:

This stage adds essential minerals that maintain the TDS and pH balance by providing Hydroxide of Na, K, and Ca, ensuring 100% safe & balanced water.

Stage -6: Post Carbon Filtration:

Filtration: This stage uses an I-1200 grade Activated Coconut Shell Carbon filter to enhance the taste of water. After these six stages safeguard purifications, the 100% safe, pure & re-mineralized alkaline water then goes into a 100% food-grade maintained 50 PSI air pressure tank. As there is no chance of purified water to have open-air contact, it saves the water from re-contamination. ULTIMA never recommends using the Open Box Reserve Tank System available in the market. Finally, to dispense the sweet water, Portable Rust Alloy Faucet has been used that can easily be set up in any convenient place. It also ensures the use of 100% safe & balanced water for drinking and kitchen solutions. 

Moreover, the well expert service team and automated service maintenance system will ensure your Ultima RO water purifier’s proper maintenance and longevity. Under a unique care program, ULTIMA also provides different water treatments such as alkaline water, hydrogen water, and antioxidant water suggested by doctors. This is why ULTIMA is the number one RO water purifier brand in Bangladesh.
