Our Quartz Sand Filter is an advanced, reliable depth filtration system engineered for industrial water pretreatment and purification. Crafted with precision-graded high-purity quartz sand as the core filter medium, it effectively captures suspended particles, sediment, colloidal contaminants, algae, and select organic impurities from water under consistent pressure. As a critical pre-treatment solution for reverse osmosis (RO), ultrafiltration (UF), and other advanced water treatment systems, it safeguards downstream equipment from fouling, extends their service life, and helps businesses minimize long-term operational and maintenance expenses.

Technical Features
Utilizes precision-graded high-purity quartz sand filter media, featuring uniform particle sizing, strong adsorption capacity, and consistent filtration results.
Dual control modes available: automatic control for unattended operation and manual control for flexible adjustments, seamlessly covering filtration, backwashing, and drainage cycles.
Versatile tank material options: FRP, Carbon Steel Lined Rubber, SS304, and SS316L, designed to resist harsh corrosive environments and adapt to diverse water quality conditions.
High-efficiency backwashing system: 5–7 minutes rapid backwash cycle, low water consumption, and supports continuous online operation without disrupting water supply.
Stable operating parameters: working pressure ranges from 0.05 to 0.6MPa, filtration rate of 5–12m/h (maximum 15m/h), and effluent turbidity consistently maintained at ≤5NTU.
Compact, space-saving structure with easy installation and commissioning, reducing on-site construction space and shortening setup time.
Key Advantages
Exceptional Filtration Performance: Eliminates over 95% of suspended solids in water, stably reduces turbidity, and delivers high-quality water for subsequent treatment processes.
Cost-Effective Operation: Low energy consumption, extended filter media service life, and straightforward maintenance procedures, effectively lowering long-term operational costs.
Wide Adaptability: Operates stably in water with a pH range of 2–13, making it suitable for various industrial water scenarios and different water source types.
Reliable & Durable: Anti-corrosion tank design paired with high-quality components ensures over 5 years of stable operation, minimizing equipment downtime and replacement costs.
Fully Customizable: We offer tailored solutions for flow rate, tank dimensions, control mode, and tank material to align perfectly with your project’s specific needs.

FAQ
How frequently should I backwash the quartz sand filter?Backwashing is recommended when the filter’s pressure difference reaches 0.05–0.07MPa. Typically, this occurs every 1 to 7 days, depending on the turbidity and impurity levels of the incoming water.
What is the expected service life of the quartz sand filter media?With proper use and regular maintenance, the quartz sand filter media can last 1 to 3 years. If you notice a significant increase in effluent turbidity or a drop in filtration efficiency, partial replacement or replenishment of the filter media is advisable.
Do you offer customized quartz sand filters for specific flow rate and size needs?Yes, we specialize in fully customized solutions. We can adjust the flow rate, tank diameter, tank material, and control system to perfectly suit your project’s unique requirements.
Can this quartz sand filter handle acidic or alkaline water sources?Absolutely. Our filters equipped 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 differentiates the automatic and manual versions of this filter?The automatic version features an intelligent control valve for unattended 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 simple operational scenarios.
