TOC Removers Are Water Treatment Equipment for Removing Total Organic Carbon from Water

Publication date: 2026-01-23 News by: admin

A TOC remover is a water treatment device specially designed to remove total organic carbon (TOC) from water. Its core function is to decompose or remove organic matter in water through physical or chemical means, thereby reducing TOC levels and improving water purity. The following explanation covers four dimensions: technical principle, core functions, application scenarios, and typical cases.

TOC removers typically employ a low-pressure, high-intensity dual-wavelength ultraviolet (185nm + 254nm) catalytic oxidation process, working as follows:

185nm ultraviolet light: directly photolyzes water molecules to produce reactive intermediates (such as hydroxyl radicals ·OH), which decompose organic matter into carbon dioxide (CO₂) and water (H₂O) through chain reactions.

254nm ultraviolet light: simultaneously kills microorganisms in the water (such as bacteria and viruses) to prevent biological contamination.

Synergistic effect: some equipment combines ozone (O₃) or persulfate to enhance oxidation capacity and improve treatment efficiency for refractory organic compounds (such as chlorinated solvents).

Deep purification of water quality: reduces TOC concentration in water to extremely low levels (e.g., ≤0.1 ppb), meeting the stringent ultrapure water requirements of the electronics/semiconductor and pharmaceutical industries.

Avoiding secondary pollution: no chemical agents are needed; organics are decomposed by physical oxidation, avoiding the chemical residue problems of conventional chemical treatment.

Ensuring production stability: in electronic chip manufacturing, trace amounts of TOC can cause wafer surface defects and affect product yields; in pharmaceuticals, excessive TOC may affect drug efficacy or cell growth.

Extending equipment life: reduces organic fouling of core components such as RO membranes and ion exchange resins, lowering maintenance costs.
