The phrase "average removal of" is correct and usable in written English.
It can be used in contexts where you are discussing the typical or mean amount of something that has been removed, such as in scientific or statistical reports.
Example: "The study measured the average removal of pollutants from the water over a six-month period."
Alternatives: "mean extraction of" or "typical elimination of".
All pilots showed a high ability to remove TSS and CODtot, with average removal of 81% and 75%, respectively.
On the contrary, none of the variables had a significant effect on the elimination of TN for which an average removal of 61 mg L−1 was obtained.
The average removal of CO was found to be higher by approximately 15% at an initial oil concentration of 50 mg/L than at 350 mg/L.
The organic substrate-based reactors removed more SO4, Fe, and Al than the limestone-only control reactor, which achieved an average removal of ∼19 mol% SO4, ∼49 mol% Fe, 36 mol% Al, and 2 mol% Mn.
Depending on the co-digestion material, the average removal of total chemical oxygen demand (TCOD) ranged between 20% (5% SM & 95% SS) and 76% (5% FW & 5% CG & 90% SS).
The average removal of BOD5 was found to be 90.43% at HLR 0.3 m d−1 and 85.75% at HLR 0.6 m d−1, while for COD it was found to be 85.59% and 79.64%, respectively.

The total antibiotic removal efficiencies depended mainly on the tertiary process, with average removals of 97.9% by reverse osmosis, 93.0% by ozone oxidation, and 84.2% by powder activated carbon adsorption when combined with conventional sludge-based wastewater treatment.
At an average hydraulic loading rate (HLR) of 19.5 mm d−1 and average surface loading rates (SLR) of 30.4 g COD m−2 d−1 and 18.4 g BOD5 m−2 d−1, the overall VF + HF CW system reached average removal efficiencies of 86.8% of TSS, 73.3% of COD, and 74.2% of BOD5.
The results indicated that at a H2S/O2 molar ratio of 1 2, an average removal efficiency of 95% and an elimination capacity of 122 g H2S m−3 h−1 was obtained.
There are numerous scrubber enhancements available to upgrade the average removal efficiencies of all types of existing scrubber systems.
