Acid-Resistant Quartz Sand Filter | Custom FRP/SS316L Filtration Gear

Our Quartz Sand Filter is an industrial-grade, high-reliability depth filtration system engineered specifically for industrial water pretreatment and purification. Adopting high-purity graded quartz sand with strict particle size screening as its core filter medium, it efficiently traps suspended particles, sediment, colloidal impurities, algae, and certain organic pollutants in water under steady pressure. As a vital pre-treatment device for reverse osmosis (RO), ultrafiltration (UF), and other advanced water treatment systems, it shields downstream equipment from contamination, prolongs their operational life, and helps enterprises reduce long-term operational and maintenance expenses.

Technical Features

Adopts high-purity graded quartz sand filter media with strict particle size screening, featuring uniform particles, strong adsorption capacity, and stable filtration results.

Provides two control modes: automatic control for unattended operation and manual control for flexible adjustment, comprehensively covering filtration, backwashing, and drainage processes.

Offers diverse tank material selections: FRP, Carbon Steel Lined Rubber, SS304, and SS316L, all designed to resist harsh corrosive environments and adapt to various water quality conditions.

Equipped with a high-efficiency backwashing system: 5–7 minutes quick backwash cycle, low water consumption, and supports continuous online operation without interrupting water supply.

Ensures 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 controlled at ≤5NTU.

Features a compact structure with small floor space, easy installation and commissioning, reducing on-site construction space and shortening the setup cycle.

Key Advantages

Excellent Filtration Efficiency: Removes more than 95% of suspended solids in water, stably reduces turbidity, and provides high-quality water for subsequent treatment steps.

Cost-Saving and Practical: Low energy consumption, long service life of filter media, and simple maintenance procedures, effectively cutting down users’ long-term operational costs.

Wide Adaptability: Operates stably in water with a pH range of 2–13, suitable for various industrial water scenarios and different types of water sources.

Durable and Trustworthy: Anti-corrosion tank structure combined with high-quality components ensures over 5 years of stable operation, minimizing equipment downtime and replacement costs.

Fully Customizable: Based on your project’s specific needs, we can customize flow rate, tank size, control mode, and tank material to perfectly meet your requirements.

FAQ

What is the recommended backwashing frequency for the quartz sand filter?Backwashing is advised when the filter’s pressure difference reaches 0.05–0.07MPa. Under normal conditions, this happens every 1 to 7 days, depending on the turbidity and impurity levels 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 last 1 to 3 years. If effluent turbidity rises significantly or filtration efficiency declines, partial replacement or replenishment of the filter media is necessary.

Can you customize quartz sand filters to meet our flow rate and size needs?Definitely. We offer fully customized solutions, adjusting flow rate, tank diameter, tank material, and control system to perfectly match your project’s actual requirements.

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

What’s the distinction between the 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, making it more suitable for small-scale applications or simple operational scenarios.
