Gas transfer efficiency (GTE) is one of the most important — and most misunderstood — parameters in water treatment, aquaculture, agriculture, and industrial processes. Whether the goal is to increase dissolved oxygen (DO), inject ozone, or deliver other gases into water, how efficiently gas actually dissolves determines performance, cost, and biological outcomes.

When discussing water quality, terms like pH, TDS, and dissolved oxygen (DO) are common. However, one of the most important but least understood parameters is ORP – Oxidation-Reduction Potential.

ORP is a direct indicator of how biologically and chemically active water is, especially in terms of microbial control, sanitation efficiency, and oxidative capacity.
