Easy-Maintain Quartz Sand Filter - Perfect for RO Pretreatment Projects

Our Quartz Sand Filter is a reliable, high-efficiency depth filtration system designed for industrial water pretreatment and purification purposes. Featuring high-grade graded quartz sand with strict particle size control as the core filtering medium, it efficiently captures suspended particles, sediment, colloidal impurities, algae, and some organic pollutants from water under stable pressure conditions. As an essential pre-treatment device for reverse osmosis (RO), ultrafiltration (UF), and other advanced water treatment systems, it protects downstream equipment from contamination and wear, extends their service life, and helps enterprises reduce long-term operational and maintenance costs.

Technical Features

Adopts high-grade graded quartz sand filter media, with uniform particle size distribution, strong adsorption capacity, and stable filtration performance.

Two control modes available: automatic control for unattended operation and manual control for flexible adjustment, smoothly covering filtration, backwashing, and drainage processes.

Multiple tank material options: FRP, Carbon Steel Lined Rubber, SS304, and SS316L, which can resist corrosive environments and adapt to various water quality conditions.

Efficient backwashing system: 5–7 minutes quick backwash cycle, low water consumption, and supports continuous online operation without interrupting normal 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 stably controlled at ≤5NTU.

Compact structure with small footprint, easy to install and commission, saving on-site construction space and shortening the installation cycle.

Key Advantages

FAQ

What’s the proper backwashing frequency for the quartz sand filter?Backwashing is recommended when the filter’s pressure difference reaches 0.05–0.07MPa. Under normal circumstances, 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?With proper use and regular maintenance, the quartz sand filter media can serve for 1 to 3 years. If effluent turbidity increases significantly or filtration efficiency drops, partial replacement or replenishment of the filter media is needed.

Can quartz sand filters be customized according to our flow rate and size needs?Yes, we provide fully customized solutions. We can adjust the flow rate, tank diameter, tank material, and control system to perfectly match your project’s unique requirements.

Is this quartz sand filter suitable for acidic or alkaline water?Absolutely. Our filters 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 automatic and manual filter versions?The automatic version is equipped with an intelligent control valve for unattended operation, including timed or pressure-differential backwashing. The manual version requires manual valve operation for backwashing and filtration, which is more suitable for small-scale applications or simple operational scenarios.
