Corrosion-resistant quartz sleeves for water treatment are core protective components specifically designed for underwater UV disinfection systems. Made from high-purity fused quartz, they offer exceptional resistance to acid and alkali corrosion and high light transmittance. They effectively isolate the lamp from water-borne corrosion while ensuring efficient transmission of 253.7 nm UV light, thereby guaranteeing the long-term, stable operation of water treatment systems. They are an ideal choice for the environmental protection and sanitation sectors.

Frequently Asked Questions (FAQ)

Q1: Why do water treatment quartz sleeves require high corrosion resistance?

A: Water treatment environments (such as sewage and industrial wastewater) often contain complex chemical substances. Quartz glass possesses excellent chemical stability; its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Except for hydrofluoric acid and hot phosphoric acid, it is inert to the vast majority of acids and alkalis, effectively addressing the corrosion challenges posed by harsh water quality.

Q2: Do quartz sleeves affect the effectiveness of UV disinfection?

A: No. We manufacture our sleeves from fused quartz with low hydroxyl content, achieving a light transmittance of over 90% in the UV spectrum (particularly at the 254 nm wavelength). This high transmittance ensures that UV light penetrates the sleeve without loss, achieving the desired disinfection and purification results.

Q3: Can quartz sleeves be customized to specific sizes and shapes?

A: Absolutely. We offer a full range of custom processing services, including cutting, end sealing, flaring, flaring, tapering, flanging, and frosting. Whether single-ended, double-ended, round-ended, or flat-ended, we can precisely customize them according to your equipment drawings.

Solving Challenges in Water Treatment Applications

In water treatment projects, engineers and technicians often face the following challenges:

Chemical Corrosion and Thermal Shock: Water containing chlorine, ozone, or acidic/alkaline chemicals, combined with the high temperatures generated by continuous UV lamp operation, can easily cause ordinary glass or plastic sleeves to age and become brittle and crack.

Decreased Light Transmittance: When scale builds up on the sleeve surface or the material oxidizes, UV light penetration is obstructed, significantly reducing disinfection effectiveness and potentially causing microbial levels in the treated water to exceed standards.

Frequent Maintenance and High Replacement Costs: It is difficult to find compatible components for non-standard equipment, and standard parts often do not fit, resulting in prolonged downtime and persistently high maintenance costs.

Our corrosion-resistant quartz sleeves, made from high-purity quartz (SiO₂ content of 99.6% or higher) and manufactured with precision, ensure long-term maintenance of high light transmittance and structural integrity under harsh water conditions, helping customers reduce equipment failure rates and extend system operational lifespans.

Material and Physicochemical Properties

The main component of this product is silicon dioxide (SiO₂), with a purity of over 99.6%. Quartz glass has a softening point of approximately 1730°C and can operate normally for extended periods at 1100°C. It also has an extremely low coefficient of thermal expansion, enabling it to withstand sudden temperature changes without shattering. Its excellent electrical insulation, moisture resistance, and explosion-proof properties ensure exceptional safety in complex water treatment environments.

Optical Performance Specifications

Manufactured to fused quartz lamp tube standards with low OH content. It exhibits excellent light transmission across the entire spectrum from ultraviolet to infrared, particularly in the 253.7 nm ultraviolet band—critical for water treatment—where transmittance remains stable at over 90%, ensuring uncompromised disinfection efficacy.

Customer Application Case: Upgrade of UV Disinfection Modules at a Large Municipal Wastewater Treatment Plant

Project Background: During a recycled water reuse retrofit at a large municipal wastewater treatment plant, the existing UV disinfection modules experienced frequent malfunctions. Because the water treated at this plant contained high concentrations of residual industrial acids and alkalis, standard glass sleeves exhibited severe corrosion and whitening within less than half a year of operation. This caused a sharp drop in UV transmittance, leading to repeated exceedances of E. coli limits in the effluent and posing significant environmental compliance challenges for the facility.

Solution: After extensive evaluation, the plant’s technical team ultimately selected our custom-made corrosion-resistant quartz sleeves for water treatment. To accommodate the unique dimensions of their open-channel disinfection modules, we provided round-ended quartz sleeves with an outer diameter of 45 mm, a wall thickness of 2 mm, and a length of 1,500 mm. We also applied a special smooth finish to the sealed ends to prevent stress concentration caused by water flow impact.

Application Results: After the new sleeves were put into service, thanks to their exceptional resistance to acid and alkali corrosion, the tubing maintained high transparency even after 18 months of continuous operation, with UV transmittance at 254 nm remaining above 92%. The plant not only completely resolved the issue of substandard disinfection but also extended the replacement cycle for lamp sleeves from the original six months to over three years. This significantly reduced equipment downtime for maintenance and lowered consumable procurement costs, earning high praise from the client.
