What is Reverse Osmosis?
Reverse osmosis
(RO) is a water purification process that uses a partially permeable
membrane to remove ions, unwanted molecules and larger particles from drinking water.
A semipermeable membrane has
small pores that block contaminants but allow water molecules to flow through.
In osmosis, water becomes more concentrated as it passes
through the membrane to obtain equilibrium on both sides. Reverse osmosis,
however, blocks contaminants from entering the less concentrated side of
the membrane. For example, when pressure is applied to a volume of saltwater
during reverse osmosis, the salt is left behind and only clean water flows
through.
How Does RO System Work?
A reverse
osmosis system removes sediment and chlorine from water
with a prefilter before it forces water through a semipermeable membrane to
remove dissolved solids. After water exits the RO membrane, it passes through a
postfilter to polish the drinking water before it enters a dedicated faucet.
What is UV Water Purifier?
In a UV water filter system, UV (Ultraviolet) rays are used to kill the harmful bacteria from the water. Hence the water is completely disinfected from pathogens. UV water purifier is good for health because it kills all the harmful microbes present in the water without affecting the taste.
How Does UV Water Purifier Works?
A UV water purifier exposes living
organisms, such as bacteria, viruses, or cysts (like Cryptosporidium and
Giardia) to a germicidal ultraviolet wavelength. With enough energy,
UV radiation at the 254-nm wavelength disrupts the DNA in pathogenic microorganisms
so they cannot reproduce. The ultraviolet light prevents bacteria
from spreading disease through drinking water.
UV dosage is the measurement of energy (in
mJ/cm²) delivered by a UV water purifier. The more dosage provided; the more
energy delivered to treat contaminated water. At a certain threshold, this
energy becomes sufficient to inactivate most of the microorganisms present in
water.
What is UF Water Purifier?
Ultrafiltration (UF) is a membrane filtration process similar to Reverse Osmosis, using hydrostatic pressure to force water through a semi-permeable membrane. Speak with A Product Specialist.
How Does UF Water Purifier Works?
Ultrafiltration uses hollow fibers of membrane material and the feed water flows either inside the shell, or in the lumen of the fibers. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane. Ultrafiltration is not fundamentally different from reverse osmosis, microfiltration or nanofiltration, except in terms of the size of the molecules it retains. When strategically combined with other purification technologies in a complete water system, UF is ideal for the removal of colloids, proteins, bacteria, pyrogens, proteins, and macromolecules larger than the membrane pore size from water.
Benefits of UltraFiltration(UF)
- No need for
chemicals (coagulants, flocculates, disinfectants, pH adjustment)
- Size-exclusion
filtration as opposed to media depth filtration
- Good and
constant quality of the treated water in terms of particle and microbial
removal
- Process and
plant compactness
- Simple
automation
- Environmentally
friendly
What
is MF Water Purifier?
Micro Filtration (MF) / UV Chamber which acts as an additional assurance of safety towards microbial contaminants.
The Micro Filtration system also does not require electricity and works with normal tap water pressure. It removes all the suspended and visible impurities like mud, dirt, sand, rust etc.…from the water.
The MF purifiers cannot remove dissolved salts or harmful metals from the water and hence you will need a RO purifier if your TDS levels are more.
