Brackish Water Desalination

Our Treatment Solutions for Brackish Water

Brackish water may have lower salt levels that sea water but is still unsuitable for use in agriculture or for stock to drink. Moerk’s desalination technology, encompassing reverse osmosis, provides a simple to use, reliable solution to brackish water. Our team can design and construct a system that will convert brackish water to a useful resource.


Brackish water is water that is saltier than fresh water but not as salty as saline water. The salt concentration for brackish water ranges from 0.5 to 30 grams per litre. It can also contain high levels of calcium and magnesium, which make the water hard as well as salty.

Brackish water is not fit for human consumption without treatment (due to the salt content) but water that is only slightly brackish can be given to livestock. It can be found as both surface and ground water, and is commonly available for use in agriculture, horticulture, governments, communities and industry. The main treatment for brackish water is membrane desalination, particularly reverse osmosis.

Moerk Water has more than a decade of experience treating brackish water to a potable standard for remote communities and agricultural clients. By treating brackish water, users are able to secure their water supply and use a previously unusable source of water.

Most Common Plants & Systems for Treating Brackish Water

Our treatment plants are individually designed to meet the specific requirements to create a supply of water that is safe for drinking or use in commercial and industrial situations.

Brackish Water Treatment

Moerk Water specialises in designing and building custom desalination plants and systems to treat various saline water sources to achieve water that is ready for commercial application and/or safe drinking water.


Typically when we think of reverse osmosis we imagine large facilities that underpin a city’s water supply or small under sink units. However, in our context, we have adapted these membrane systems to be both transportable and optimised for whatever scale various agricultural and commercial concerns require.


Moerk’s water treatment technology can convert a wide range of water types, including sea water, brackish water and contaminated water into safe drinking water that meets World Health Organisation water quality standards.
