Pro-Grade Quartz Sand Filter - High-Performance RO/UF Pretreatment for Industry

Our Quartz Sand Filter is a professional-grade, heavy-duty depth filtration system engineered specifically for industrial water pretreatment and purification. Featuring high-purity graded quartz sand (undergoing rigorous particle size screening) as its core filter medium, it efficiently traps suspended solids, sediment, colloidal impurities, algae, and partial organic contaminants in water under consistent pressure. As a critical pre-treatment component for reverse osmosis (RO), ultrafiltration (UF), and other advanced water treatment systems, it safeguards downstream equipment from fouling and corrosion, prolongs their operational lifespan, and helps industrial clients cut down long-term operational and maintenance expenses.

Technical Features

Features high-purity graded quartz sand filter media with rigorous particle size screening, boasting uniform particle distribution, strong adsorption capability, and consistent filtration results.

Offers two operational modes: automatic control for 24/7 unattended operation and manual control for flexible adjustment, seamlessly covering filtration, backwashing, and drainage procedures.

Provides multiple tank material selections: FRP, Carbon Steel Lined Rubber, SS304, and SS316L, all capable of withstanding harsh corrosive environments and adapting to diverse water quality conditions.

Comes with an efficient backwashing system: 5–7 minutes quick backwash cycle, minimal water waste, and supports continuous online operation without disrupting normal water supply.

Delivers stable operating performance: working pressure ranges from 0.05 to 0.6MPa, filtration rate of 5–12m/h (maximum 15m/h), and effluent turbidity stably kept at ≤5NTU.

Boasts a compact structure with minimal floor space, easy installation and commissioning, saving on-site construction space and reducing the installation timeline.

FAQ

How often should I backwash the quartz sand filter?Backwashing is advised once 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?With proper usage and regular maintenance, the quartz sand filter media can last 1 to 3 years. If effluent turbidity rises noticeably or filtration efficiency drops, partial replacement or replenishment of the filter media is required.

Can you customize quartz sand filters to fit our flow rate and size needs?Absolutely. We provide fully tailored solutions, adjusting flow rate, tank diameter, tank material, and control system to perfectly match your project’s specific requirements.

Is this quartz sand filter compatible with acidic or alkaline water?Yes. Our filters with FRP or stainless steel (SS304/316L) tanks offer strong acid and alkali resistance, allowing stable operation in water with a pH value of 2–13.

What distinguishes the automatic and manual filter versions?The automatic version includes 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 setups.
