Reverse Osmosis

There are a variety of solutions and technologies available for water purification such as Boiling, Water Purifier, Water Chlorination, Distillation and Solar Purification but at Aqua-Veritas we concentrate on Reverse Osmosis as we believe this is one of the best methods which helps retain the necessary minerals and nutrients while removing any harmful impurities.

History of Reverse Osmosis

Reverse Osmosis was first discovered in France 1748 by Jean Antoine Nollet.


It was later discovered that membranes with particularly high flux and low salt passage could be made by interfacial polymerization of m-phenylenediamine and trimesoyl chloride. By the late 1970s reverse osmosis was operational on a large scale


Reverse Osmosis is being used for Desalination, Utility Water treatment, Wastewater Treatment & Reuse and Process Water. It is being used in many industries such as Energy, Food & Beverage, Healthcare, Chemical & Petrochemical, Municipal and Water & Wastewater Treatment.


Reverse Osmosis History


But it was not until 1950s that fresh water was produced from seawater at the University of Florida. This was not commercially viable due to high flux.


Over 15,000 desalination plants were up and running, or planned for, around the world.

Reverse Osmosis Today

Reverse Osmosis is a commonly used for desalination. It uses no chemicals to treat wastewater, making it an environmentally friendly alternative to other wastewater treatment technologies. Moreover, Reverse Osmosis requires less maintenance and offers a higher efficiency of water production than other water treatment methods.

Reverse Osmosis Process
The process:
Reverse osmosis - removes impurities from unfiltered water, by using pressure to force the water through a semipermeable membrane which block impurities but allow only water molecules to pass through. Water flows from the more concentrated side (salt water) of the membrane and through reverse osmosis to the less concentrated side (fresh water) to provide clean drinking water.

Advantages of using Reverse Osmosis:
•    Production of drinking water.
•    Can be scaled up to almost unlimited size.
•    A variety of water sources can be used.
•    The technology removes organic and inorganic impurities.
•    Minimum chemical use.
•    Low operating and maintenance costs.

Future Market for Reverse Osmosis

The rising awareness about these advantages is expected to fuel the growth of the Reverse Osmosis Membrane Market during the forecast period.

The reverse osmosis membrane market size is expected to reach USD 7.09 Billion in 2030

According to the report given by the United Nations, the scale of water security investment is expected to surge at an exponential rate, in the coming years. Global estimates have been ranging from US$6.7 trillion, by the year 2030, to around US$22.6 trillion by the year 2050. Reverse Osmosis membrane market in Asia-Pacific accounted for largest revenue share in 2021 and is expected to register a faster revenue CAGR during the forecast period, which can be attributed to increasing awareness about clean drinking water, stringent government regulations for effluent discharge, and rising demand for fresh water from industries.

Turning Desalination Brine into a useful resource

One Aqua-Veritas container that produces 1,000 m³/day of drinking water from high salinity sea water (Atlantic, Pacific Ocean etc.) also in normal conditions produces between 1,500 to 2,000 m³/day of a waste product called brine. Currently a very high percentage of this highly concentrated brine is pumped straight back into the sea all over the world which can be costly and must be managed to protect the ecosystems. The desalination industry is developing new processes to convert this brine into useful chemicals such as sodium hydroxide and hydrochloric acid which can be used in many industrial processes.

One aspect of the brine that Aqua-Veritas is currently developing is the extraction of the salt from the brine as this will reduce the need to pump the concentrated brine back into the sea. The salt can be refined for a variety of uses from human consumption, fertilizers, soap production and many other uses in the manufacturing and chemical industry.

Many countries globally have a massive shortage of salt and the Philippines for example imports around 96% of its salt yet has a shoreline of 36,000 km. Aqua-Veritas containerized plants could not only provide clean drinking water but also provide an enormous amount of salt and reducing the need for expensive salt imports.

As an example: If One Aqua-Veritas container is located in the Philippines and using sea water as incoming source, that container will produces between 90 to 120 metric tons of sea salt from the waste product called brine every day after evaporation.
