Use Of Ultrafiltration In Water Treatment

The use of ultrafiltration in water treatment is a burgeoning method of cleansing water and has gained wide popularity in the past few decades. The procedure is characterized by several benefits that put it above several other water treatment strategies. These benefits show that the use of ultrafiltration in water treatment has the potential to help eradicate the problems associated with water security.

Ultrafiltration is a procedure based on the traditional filtration process where a fluid is made to pass through a medium. The medium, which is often characterized by the presence of small pores is selective by design and prevents particulate matter of some diameter from passing through. Hence, the efficiency of any given filtration medium is dependent on the relative sizes of the membrane compared to those of the particles involved.

The ultrafiltration process is often reliant on the exertion of pressure on the water to force it through the membranes. Traditionally, the process has been limited to desalination processes. More recently, however, several needs are met such as the removal of bacteria, organic matter, and even odor. Ultrafiltration is related to the other forms of filtration including nanofiltration and Reverse Osmosis.

Ultrafiltration in water treatment refers to the elimination of contaminants from polluted water by compelling it through a permeable membrane. Ultrafiltration may also be applied to a range of other applications such as the treatment of wastewater.

Ultrafiltration may often be used in combination with other water treatment systems. This works to compliment the other purification technologies, hence, leading to high-quality purified water. For instance, ultrafiltration systems improve the functionality of reverse osmosis membranes, which, left on their own, can degrade rapidly. A pretreatment process that employs filtration systems is sure to lower the solutes in saline water using the reverse osmosis process. In effect, this works to extend the working lives of the membranes.

Scientific research on filtration systems has increasingly unveiled new materials capable of achieving greater ultrafiltration efficiencies with decreased use of energy. This not only means that the initial purchasing costs will decline, but the energy cost used to run the devices will also be economized.

Ultrafiltration helps eliminate various contaminants in water, both organic and inorganic. An average diameter of one to 0.01 micrometers of contaminants is often removed. However, it is essential to observe that the process does not eliminate dissolved particulates in the water. A more efficient method of eliminating the dissolved solids is the Water Distillation process. 

Ultrafiltration can be employed for the treatment of water from various origins both surface and underground. It can also act as the final process in the treatment of recycled wastewater. One key element of the process is that it eliminates a wide range of microorganisms and heavy metals that may be present in a water sample.

• No chemicals are required for its operation. This means no introduction of new chemicals is made such as processes such as chlorination.
• The relative costs of the systems compared to others such as reverse osmosis is low.
• The use of the technology is environmentally feasible.
• The products that employ this technology are usually compact, hence, do not demand too much room.
• The technology ensures that the quality of the product is always high regardless of the quality of the feed water. Hence, this ensures that the resultant water is often compliant with the set regulations. The efficacy of the system also that the quality might far exceed the very set regulatory frameworks.

• There is a possibility of microorganisms growing on the surfaces of the membrane which might affect the water quality if not eliminated periodically. However, the cleaning process is often a fairly simple process, which helps maintain the device.

Ultrafiltration is a reliable means of availing water of certain desired quality. In instances where the feed water does not exhibit several impurities, simpler techniques of water treatment suffice. For example, some water from springs might require little to no additional treatment procedures. However, water from dams might be characterized by the presence of microorganisms and suspended solids. In such instances, the particulate matter might be removed by the use of alum and chemical treatment such as chlorination or hydrogen peroxide treatment method to attain disinfection. The more recent technologies such as water vapor harvesting might not require any additional treatment.

The fact that the process of ultrafiltration does not employ the addition of any chemical compounds into the water is a plus for the health of the consumer. Many chemical treatment methods have been accused of increasing the chances of developing cancers as a long-term side effect. Furthermore, simpler techniques such as boiling do not exhibit similar capacities to eliminate particulate matter.

The use of ultrafiltration in water treatment is an increasingly popular way of achieving water sanitization. Besides being efficient in its application, the technology is easy to use in the home setup. As a result, it ought to be incorporated into households if the feedwater is determined to have large concentrations of particulates in water as well as contamination by a range of microorganisms. The systems can also be used to offer further treatment to tap water to guarantee its safety. The treatment of tap water for such a purpose will help ensure that any toxic elements that might still be in the water or any resultant THMs are eliminated. This is highly likely since tap water is often prone to infection especially due to bursts in the lines.

Ultrafiltration is a process that takes the traditional filtration systems to a whole new level by ensuring that a wide array of contaminants is removed. The system is part of a range of other modern filtrations systems including microfiltration and reverse osmosis. The choice of the filtration method to be used in any particular setting solely depends on the quality of the feed water, the desired quality, and economic viability as the most essential factors to be considered.
