As one of the standard technologies in water purification, reverse osmosis systems (RO) is widely used within a commercial, domestic, and industrial environment.
Reverse osmosis water treatment systems are the process of water purification whereby the impurities in the water are removed. Of course, there are many other forms of water purification besides the reverse osmosis systems, and the choice of which to use is ultimately down to the requirements of the water treatment application and the level of purification required.
Throughout the universe, there is one molecule that man seeks above all others for its discovery in the atmosphere of some distant planet. This would immediately unleash mankind’s wildest dreams.
Water … H2o … what a wonder!! Water is used in so many different ways, it is perhaps unrealistic to expect water to meet all of the demands that are made of it. With the right types of Industrial or commercial water treatment systems, water can and does meet all of its obligations.
Industrial companies, Hospitals, Car manufacturers, Nuclear plant stations, farmers, nurseries, Electro-platting companies, Hospitals, and domestic homemakers… each has special requirements in terms of water treatment quality.
Water is the most common mineral on the earth’s surface. Water begins its never-ceasing cycle as vapour in the atmosphere.
The sources of the water provided to most water treatment plants can be classified into one of the following categories: Groundwater, Surface water, and seawater. Ground water used for most industrial water treatment plant applications may range from 1000 mg/L TDS to Brackish up to 5000 mg/L TDS. Seawater wells are used to supply the salty water which usually has a TDS level of 35,000 mg/L TDS.
Over the last millennium, Scientists and engineers have worked on creating productive and smart commercial and industrial water treatment processes. Keeping in mind, the importance of protecting our health, the ecosystem and the quality of the water, we now have guidelines mandated by the World Health Organisation (WHO). In addition to the WHO, local counties and/or municipalities can add additional guidelines to the guidelines already in place making it more stringent of a process.
The process of water treatment is broken down into three steps, primary, tertiary and secondary treatment. The entirety of the process includes a number of specialties to complete including; physical, biological, chemical. Mechanical, and so much more.
The first water treatment step that is taken, if the water is coming from surface water or river source, is to remove large solid materials through a trash screen and sedimentation channel at the water intake, then to chemically injecting Aluminium sulphate (Alum) or Ferric sulphate to allow the coagulation process to take place. The Clarifier in which a cationic polymer and lime are added is to assist in the inoculation of the solids.
Catalytic conversion filters: This process removes all the bad pathogenic particles from the water and modifies them into harmless basic elements. Once used, the Catalytic process is similar to the reduction of automobile emissions that was. These filters also leave the water with a negative charge and alkalize it.
Far infra-red systems: This format utilizes the natural generation of energy by using natural elements. This process does not cause water filtration but can be used to soften water, create negatively charged water, and modify the molecules into smaller hydrated forms.
While most of us don’t even realize there is such a need for the conservation and filtration of water it is imperative that you pass this knowledge on to the younger generations as they will be most affected by the reduction in freshwater supplies.
‘Water Filtration Becomes More Important’.
The purity of our water is absolutely mandatory for survival making water filtration a necessity instead of the luxury that some folks believe it to be. The importance of water filtration discoveries and processes is vital at this time.
In numerous locations of the globe, water resources are insignificant and cannot stand up to the water demands. There are Worldwide concerns that freshwater resources are at risk, both in terms of water replenishment and water quality.
Water filtration is the term used to identify the process of impurity removal from water by way of either a barrier, chemical or biological. Of course, there are varying formats of water filtration and some of those are;
Activated Carbon Filters Media, easy to install, low cost, and available for commercial or domestic usage.
Carbon Filters – Two Basic Types:
Carbon Block: the flow rate using this filter can be slower than the Granulated Activated Carbon water filtration system.
Granulated Activated Carbon: This is the most widely used Carbon filter. Its granules come in varying sizes; the use of smaller granules can result in a channeling effect.
The activated carbon filtration process is used in the pre-treatment process, primary treatment application, and wastewater processes. Primarily used in hospitals, food establishments, water treatment facilities, and domestic use.
Pleated Cellulose: this filter is used with treated water and provides a maximum flow with little pressure loss.
Pleated Polyester: this filter has limited reusability and is chemical and bacteria resistant:
Spun Polypropylene: implements the process of holding the dirt and capturing particles from the water supply.
Ceramic water filters: This is a bacteriologically safe water filtration format that is lightweight and primarily used by backpack campers. The flow rate can be slow and the filter tends to build up debris from contaminants that require cleaning off at times.
Reverse osmosis filters: This process uses water pressure for its performance, and offers excellent quality water. Water filtration using reverse osmosis creates water that is similar to distilled water.
Minerals can be implemented into the water after the water filtration process is complete.
