Product parameter:
Our Quartz Sand Filter is a high-reliability depth filtration solution designed specifically for industrial water pretreatment and purification processes. Utilizing high-grade graded quartz sand as the core filtering medium, it efficiently removes suspended particles, sediment, colloids, algae, and certain organic pollutants from water under steady pressure. As an essential pre-treatment component for reverse osmosis (RO), ultrafiltration (UF), and other advanced water treatment systems, it ensures the smooth operation of downstream equipment, extends their service life, and helps enterprises reduce long-term maintenance expenses.
Technical Features
Adopts high-purity graded quartz sand filter media, boasting uniform particle size, strong adsorption capacity, and consistent filtration results.
Two control modes available: automatic control for hands-free operation and manual control for flexible adjustment, covering all filtration, backwashing, and drainage procedures.
Multiple tank material options: FRP, Carbon Steel Lined Rubber, SS304, and SS316L, capable of withstanding various corrosive environments and adapting to different water quality conditions.
Efficient backwashing system: 5–7 minutes quick backwash cycle, low water consumption, and supports continuous online operation without interrupting the water supply process.
Stable operating parameters: working pressure 0.05–0.6MPa, filtration rate 5–12m/h (maximum 15m/h), and effluent turbidity consistently maintained below 5NTU.
Space-saving compact design, simple installation and commissioning, helping save on-site construction space and reduce installation time.
Key Advantages
Superior Filtration Capability: Eliminates over 95% of suspended solids in water, stably reduces turbidity, and delivers high-quality water for subsequent treatment steps.
Cost-Effective Operation: Low energy consumption, long service life of filter media, and straightforward maintenance, effectively cutting down long-term operational costs for users.
Broad Adaptability: Operates stably in water with a pH range of 2–13, suitable for various industrial water scenarios and different types of water sources.
Dependable & Durable: Anti-corrosion tank design paired with high-quality components ensures over 5 years of stable operation, minimizing equipment replacement and maintenance frequency.
Highly Customizable: We offer tailored solutions for flow rate, tank dimensions, control mode, and tank material to meet your project’s unique requirements.

FAQ
How frequently should backwashing be performed on the quartz sand filter?Backwashing is recommended when the filter’s pressure difference reaches 0.05–0.07MPa. Typically, this happens every 1 to 7 days, depending on the incoming water’s turbidity and impurity levels.
What is the service life of the quartz sand filter media before replacement?With proper usage and regular maintenance, the quartz sand filter media can last 1 to 3 years. If you observe a notable increase in effluent turbidity or a drop in filtration efficiency, partial replacement or supplementation of the filter media is necessary.
Can you provide customized quartz sand filters to match our specific flow rate and size requirements?Absolutely. We offer fully tailored solutions, including flow rate, tank diameter, tank material, and control system, to perfectly align with your project’s actual needs.
Is this quartz sand filter suitable for use with acidic or alkaline water sources?Yes, it is. Our filters equipped with FRP or stainless steel (SS304/316L) tanks have excellent acid and alkali resistance, enabling stable operation in water with a pH value of 2–13.
What’s the difference between the automatic and manual versions of this filter?The automatic version comes 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 more suitable for small-scale applications or scenarios with simple operational needs.
