Product parameter:
Our Quartz Sand Filter is a robust, high-efficiency depth filtration system engineered for heavy-duty industrial water pretreatment and purification. Built with advanced graded high-purity quartz sand as the core filter medium, it effectively captures suspended particles, sediment, colloidal impurities, algae, and selected organic contaminants from water under stable pressure conditions. As a critical pre-treatment unit for reverse osmosis (RO), ultrafiltration (UF), and other advanced water treatment systems, it safeguards the performance of downstream equipment, extends their operational lifespan, and helps businesses cut down on long-term maintenance costs.
Technical Features
Utilizes advanced graded high-purity quartz sand filter media, featuring uniform particle distribution, strong adsorption capability, and reliable filtration performance.
Dual control options: automatic control for hands-off operation and manual control for on-demand adjustments, covering all key processes including filtration, backwashing, and drainage.
Versatile tank material choices: FRP, Carbon Steel Lined Rubber, SS304, and SS316L, designed to resist harsh corrosive environments and adapt to diverse water quality scenarios.
High-performance backwashing system: 5–7 minutes rapid backwash cycle, low water usage, and supports continuous online operation without disrupting the water supply.
Consistent operating parameters: working pressure of 0.05–0.6MPa, filtration rate of 5–12m/h (maximum 15m/h), and effluent turbidity steadily kept below 5NTU.
Compact, space-efficient design with simple installation and commissioning, reducing on-site construction space and shortening setup time.
Key Advantages
Exceptional Filtration Performance: Removes over 95% of suspended solids in water, consistently reduces turbidity, and delivers high-quality water for subsequent treatment processes.
Cost-Efficient Operation: Low energy consumption, extended filter media service life, and hassle-free maintenance, effectively lowering the total cost of ownership for users.
Wide-Ranging Adaptability: Operates stably in water with a pH range of 2–13, making it suitable for various industrial water applications and different water source types.
Durable & Dependable: Anti-corrosion tank construction paired with high-quality components ensures over 5 years of stable, uninterrupted operation, minimizing equipment downtime and replacement costs.
Fully Customizable: We provide tailored solutions for flow rate, tank size, control mode, and tank material to perfectly meet the unique requirements of your project.

FAQ
What’s the optimal backwashing frequency for the quartz sand filter?Backwashing is recommended when the filter’s pressure difference reaches 0.05–0.07MPa. Under normal conditions, this occurs every 1 to 7 days, depending on the turbidity and impurity content of the incoming water.
How long can the quartz sand filter media be used before needing replacement?With proper use and regular maintenance, the quartz sand filter media has a service life of 1 to 3 years. If you notice a significant rise in effluent turbidity or a decline in filtration efficiency, it’s time to partially replace or replenish the filter media.
Do you offer customized quartz sand filters to fit our specific flow rate and size needs?Yes, we specialize in fully customized solutions. We can tailor the flow rate, tank diameter, tank material, and control system to align perfectly with your project’s unique requirements.
Can this quartz sand filter handle acidic or alkaline water sources?Absolutely. Our filters with FRP or stainless steel (SS304/316L) tanks offer excellent acid and alkali resistance, allowing stable operation in water with a pH value of 2–13.
What distinguishes the automatic and manual versions of this filter?Theautomatic version is equipped with an intelligent control valve for unmanned operation, including timed or pressure-differential backwashing. The manual version requires manual valve operation for backwashing and filtration, making it ideal for small-scale applications or scenarios with basic operational needs.
