Precautions for ultraviolet removal of TOC1Understanding TOCBefore discussing UV removal TOC, we first need to understand what TOC is.
TOC, or Total Organic Carbon, is a measure of organic matter in water that describes the amount of organic matter in water.
TOC is one of the important parameters for water quality evaluation, and excessive TOC content may lead to water pollution.
2.The principle of ultraviolet removal of TOC, ultraviolet removal of TOC makes use of the high energy and strong oxidizing power of ultraviolet rays, which can oxidize and decompose organic matter in water into inorganic matter or small molecule organic matter.
Ultraviolet light can directly irradiate organic matter in water, causing it to be excited by ultraviolet energy and undergo a chemical reaction, which eventually decomposes into harmless substances.
3.Advantages of UV TOC Removal - No Secondary Pollution: UV TOC Removal does not require the addition of any chemical reagents, so there will be no secondary pollution.
Safety and environmental protection: Ultraviolet light is a physical treatment method, which has no obvious effect on other components in the water, and is safe for the human body and the environment.
High efficiency and energy saving: ultraviolet light reaction speed is fast, high processing efficiency, and the energy consumption of ultraviolet equipment is relatively low.
4.Precautions for TOC removal using ultraviolet light - Wavelength selection: In the ultraviolet spectrum, ultraviolet radiation with a wavelength of 254nm has the best effect on TOC removal.
When choosing a UV device, make sure it has a wavelength of 254nm.
Light intensity and treatment time: Light intensity and treatment time are important factors affecting the effectiveness of UV TOC removal.
In general, the higher the light intensity and the longer the processing time, the better the removal effect.
In actual use, the light intensity and treatment time of ultraviolet equipment should be reasonably adjusted according to the water quality situation and demand.
Water pretreatment: Ultraviolet removal of TOC has high requirements for water quality, and if the water contains a high concentration of suspended solids, particulate matter or organic matter, it will reduce the transmittance of ultraviolet rays and affect its removal effect.
Before using UV equipment, the water quality needs to be properly pre-treated, such as filtration, sedimentation, etc.
Regular maintenance: After a period of use, the lamp will gradually deteriorate and the intensity of ultraviolet radiation will decrease.
Lamps need to be replaced regularly to ensure the normal operation of the equipment.
Summary: Ultraviolet TOC removal is a chemical-free, non-secondary pollution, energy-efficient water treatment method.
When using UV equipment for TOC removal, it is important to pay attention to the selection of wavelength, light intensity and treatment time, water quality pretreatment, and regular maintenance.
This method is widely used and is very effective for water treatment.
