Long-Lasting Quartz Sand Filter - 5+ Years Stable Performance for Industry

Our Quartz Sand Filter is a cost-effective and reliable depth filtration system designed for industrial water pretreatment and purification needs. Featuring high-quality graded quartz sand with strict particle size control as the core filter medium, it effectively traps suspended particles, sediment, colloidal substances, 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 protects downstream equipment from damage, extends their service life, and helps enterprises reduce long-term operational and maintenance costs.

Technical Features

Adopts high-quality graded quartz sand filter media with precise particle size distribution, strong adsorption performance, and consistent filtration results.

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

Diverse tank material options: FRP, Carbon Steel Lined Rubber, SS304, and SS316L, which are resistant to harsh corrosive environments and adaptable to various water quality conditions.

Efficient backwashing system: 5–7 minutes fast backwash cycle, low water consumption, and supports continuous online operation without interrupting normal water supply.

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.

Space-saving design with simple installation and commissioning, reducing on-site construction space and shortening the overall setup time.

Key Advantages

FAQ

How often is backwashing required for 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 turbidity and impurity levels of the incoming water.

What is the 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 effluent turbidity increases significantly or filtration efficiency drops, partial replacement or replenishment of the filter media is necessary.

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

Is this quartz sand filter suitable for acidic or alkaline water?Definitely. Our filters with FRP or stainless steel (SS304/316L) tanks have strong 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 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.
