Supply of Water Purification Technologies

Reverse Osmosis Technology

Reverse Osmosis(RO) technology can treat all 3 types of contamination(Physical,chemical & microbiological)present in the source water.

There are 5 stages of Filtration in RO Technology

• 1. Sand Filtration
• 2. Corbon Filtration
• 3. Micron Filtration
• 4. Membrane
• 5. Ultra Violet Filtration

Ultra Filtration(UF) Technology

Ultrafiltration (UF) is a pressure-driven barrier to suspended solids, bacteria, viruses, endotoxins and other pathogens to produce water with very high purity and low silt density. Ultrafiltration (UF) is a variety of membrane filtration in which hydrostatic pressure forces a liquid against a semi permeable membrane.

The UF membrane is also so small that it can filter out all dust and other particles and make the water safe to drink. The only problem with UF water purifier is that in case any harmful dissolved salts are present in the water the UF membrane cannot filter it out.

Reverse osmosis and ultrafiltration are two of the most powerful and effective water filtration systems on the market. Though both RO and ultrafiltration possess remarkable filtration properties, the systems do have key differences. From mineral retention to ease of installation and cost of maintenance, each system has unique advantages and disadvantages.

The Purification by RO and UF are based on membranes. But the difference between the two is in the size of the pores in of their membranes. In an RO membrane the filtering pores are so small that it can even filter out salt molecules from the water. In the UF membrane the pores are larger and so it cannot filter out salt molecules.

The advantage of the UF water purifier is can filter out all other physical impurities and is sure to filter out any disease causing germs, including the smallest of viruses. The UF membrane is also so small that it can filter out all dust and other particles and make the water safe to drink.

Though the UF membrane is capable to filter out viruses from water, it cannot filter out the salts and metals from the water.

The only problem with UF water purifier is that in case any harmful dissolved salts are present in the water the UF membrane cannot filter it out. Only an RO water purifier can filter out harmful dissolved salts from the water. That is why the RO water purifier is considered superior to an UF water purifier.

Nano Filtration(NF)Technology

Nanofiltration is a membrane filtration-based method that uses nanometer sized pores through which particles smaller than 10 nanometers pass through the membrane. Nanofiltration membranes have pore sizes from 1-10 nanometers, smaller than that used in microfiltration and ultrafiltration, but a little bit bigger than that in reverse osmosis. Membranes used are predominantly created from polymer thin films.

One of the main advantages of nanofiltration as a method of softening water is that during the process of retaining calcium and magnesium ions while passing smaller hydrated monovalent ions, filtration is performed without adding extra sodium ions, as used in ion exchangers. Many separation processes do not operate at room temperature (e.g. distillation), which greatly increases the cost of the process when continuous heating or cooling is applied. Performing gentle molecular separation is linked with nanofiltration that is often not included with other forms of separation processes (centrifugation). These are two of the main benefits that are associated with nanofiltration. Nanofiltration has a very favorable benefit of being able to process large volumes and continuously produce streams of products.

A main disadvantage associated with nanotechnology, as with all membrane filter technology, is the cost and maintenance of the membranes used.[Nanofiltration membranes are an expensive part of the process. Repairs and replacement of membranes is dependent on total dissolved solids, flow rate and components of the feed. With nanofiltration being used across various industries, only an estimation of replacement frequency can be used. This causes nanofilters to be replaced a short time before or after their prime usage is complete.

Ultra Violet (UV) Filtration Technology

The Ultraviolet filtration system makes use of ultraviolet rays that expose microorganisms with the light that disinfects the water. Doing this helps in inhibiting the growth of bacteria and other microorganisms in the water.

UV systems can penetrate the pathogen in the water, attacking the core of the microorganism. It is a great way of eliminating the ability of bacteria to multiply and wreak havoc when being used in households.

An ultraviolet water system uses the wavelength of the ultraviolet rays as the source of disinfection to impede any microbial growth. Ensuring the people using this product that safe water is guaranteed.

Beside providing solutions for communities,we all also have compact units for schools, hospitals and for other institutional requirements. We also supply domestic water purification units based on (RO+UV+UF) technology
