The reverser osmosis is a process in which the water is forced to go through a semipermeable membrane, from a more concentrated solution to a lesser one, using pressure.
It’s a natural diffusion phenomenon that occurs when two solutions have different concentration.
The membrane retains the mineral substances that are dissolved in the water, as well as the bacteria or chemicals and organochlorine compounds.
To calculate the cost and specifications of a revers osmosis equipment we need to know the follow details:
– A chemical analysis of the raw water that is going to be treated.
– Daily consumption.
– The water quality that we want to obtain.
– What is the water for.
In every reverse osmosis (R.O) installation we need a preprocessing so it can achieve the maximum efficiency. This step is as important as the installation itself.
The choice of the preprocessing will be the result of a study in which the quality of the water to be filtered and the requirements of the agitation are considered.
It can be composed of filtration, chlorination, acidification with a pH adjustment, dosage of sequestering products, descalation and removal of residual chlorine.
– Drinking and industrial water production in places where only saltwater is accessible.
– Production of high quality water for water heaters, the pharmaceutical industry, perfumeries, electronics, the surface treatment industry…
– Food industry
– Hospitals
– Air conditioning
– Research
– Purification of seawater and saltwater
– Home: These equipment deserve special attention because nowadays their implementation is very widespread. They are generally installed under the sink and provide drinking water, cooking water and water for icing. Its performance varies between the 60 and 100 L/day. If the hardness is high is preferable to previously decalcify.
