CSG Water Management and Treatment
Ralph Gunness, Field Environmental & Sustainability Manager, GLNG Project, Fluor

• Water Terms and Definitions
There are a number of key water quality parameters (terms) used to determine the existing quality of water, which assist in determining optimum treatment conditions. You should have knowledge of these essential water quality parameters if you are going to work with, measure and treat waste water.

• Soils
This section is about learning soil terminology and processes used in measuring and monitoring soil chemistry and soil water. If the irrigation of treated waste water is the most sustainable solution, then the identification of the receiving soil types and their soil characteristics is essential in the process to maximise the beneficial use of the waste water and the sustainability of the project over the long term.

• Water Treatment and Osmosis
Most mining or coal seam gas (CSG) waste waters contain solids and fine particles. It is essential that they are removed from the feed water at the front end of the water treatment process. The terms and processes relating to this are discussed below.

• Beneficial Uses
This section is split into two parts: firstly, the beneficial use of untreated CSGw or mine water and secondly, the beneficial uses of treated CSGw.

• Soil, Salts and Sodium
This section discusses the key parameters for the application of treated CSGw to soil using irrigation and scientific analysis methodology.

• Brine Management
A discussion of current treatment methods.
