Two Advanced Types of Water Filtration Systems available in South Africa
WaterIcon manufactures several types of water filtration systems in South Africa, two of which are briefly introduced below. First, however, a look at what filtration entails.
Filtration is a stage in water treatment and follows after clarification of the water. Through the use of special filtration equipment and techniques, remaining suspended particles as well as micro pollutants in addition to heavy metals can be removed. The clarification process already helps to remove the above, but through filtration any remaining particles can be removed. Filtration systems in South Africa are used for applications such as:
- Process water treatment.
- Municipal wastewater processing to ensure drinking water.
- Industrial effluent water treatment.
- Protection of equipment against particles in water.
Several types of filters are used including for instance:
- Rapid sand
We mainly make use of sand filtration as well activated carbon filtration systems. Other products used in our filtration systems include, but are not limited to:
- Activated alumina
Two of the advanced water filtration systems that we install in South Africa deserve a closer look.
Ultra Filtration (UF) Systems
We have completed several projects where we manufactured UF systems in our workshop in Johannesburg and have installed such as client premises across Southern Africa. Ultra filtration is used for pre-treatment of water and applied in processes such as recovery of vaccines from fermentation broths, clarification of fruit juices, and fractionation of proteins. The filtration is also used for other types of water pre-treatment processes including:
- Downstream processing of biotechnology derived proteins.
- Concentration of milk before making cheese.
- Laboratory grade water purification.
- Disinfection of drinking water.
- Endocrine and pesticide removal.
Our product range includes an extensive range of UF membranes, UF units from 1000 LPH and customised units as well as stainless steel and fibre glass housings.
What is Ultra Filtration?
It’s a filtration membrane where hydrostatic pressure is used to force the water to be purified, through a semi-permeable membrane. The membrane consists of a material that allows only specific particles through while preventing others to go through the membrane. The membranes are excellent in preventing micro-organisms to go through. This helps to ensure odour free and clear water. The main reasons for using this type of filtration as opposed to normal disinfection are that it can be automated, the filter systems are compact in design, and the need for chemicals in the water treatment is eliminated.
Ultraviolet Filtration Systems
The second advanced option is that of ultraviolet filtration. We distribute the Wonder brand of UV filtration systems and can also supply spares and accessories throughout the African continent. No installation is too small or too big for us to handle as is evident in our supply of systems ranging from small residential units to larger units applicable in industry. Easy to install and maintain, the compact systems are now widely used throughout South Africa.
The filtration method has several advantages when compared to normal chemical water disinfection systems. It’s a non-chemical method that also eliminates the risk of overdosing the water with disinfectants. It destroys micro-organisms without the introduction of toxic by-products. You won’t need to store chemicals which can be a health hazard and with this method little control is needed. The final product doesn’t smell of chemicals and it is an energy efficient disinfecting method. With the use of our UV filtration systems you can polish, disinfect, and sterilise water.
How does UV Filtration Work?
The UV light brings about the forming of linkages on DNA and prevents micro-organisms and bacteria from reproducing. Because the microbes cannot reproduce they lose their danger. UV light is energy efficient and doesn’t contain harmful chemicals that can destroy valuable properties. The method is preferred over chlorine in many instances simply because chlorine requires close monitoring, and because chlorine is an additive it affects the taste of water. It changes the pH level of the water and can easily react with other ingredients. This is especially dangerous in the disinfecting of industrial water. UV filtration thus offers a safe alternative.
