High-Efficiency Quartz Sand Filter - RO/UF System Pretreatment for Industrial Water

Our Quartz Sand Filter is a reliable, high-performance depth filtration system designed for industrial water treatment and pretreatment. Featuring high-purity graded quartz sand as the core filter medium, it efficiently removes suspended solids, sediment, colloids, algae, and partial organic impurities from water under controlled pressure—effectively reducing turbidity and improving water quality. As a critical pre-treatment solution for reverse osmosis (RO), ultrafiltration (UF), and other advanced water treatment systems, it ensures stable operation of downstream equipment, extends their service life, and reduces maintenance costs for your project.

Technical Features

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

Dual control modes available: automatic (unmanned operation) and manual control, supporting seamless filtration, backwashing, and drainage processes.

Multiple tank material options: FRP, Carbon Steel Lined Rubber, SS304, and SS316L, providing strong corrosion resistance to adapt to different water environments.

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

Stable operating parameters: working pressure 0.05–0.6MPa, filtration rate 5–12m/h (max 15m/h), and effluent turbidity ≤5NTU for consistent performance.

Compact structure, small footprint, and easy installation/commissioning—saving space and reducing on-site construction time.

FAQ

How often do I need to perform backwashing for the quartz sand filter?

Backwashing is recommended when the pressure difference of the filter reaches 0.05–0.07MPa. Under normal circumstances, this happens every 1–7 days, depending on the turbidity and impurity content of the incoming water.

When should I replace the quartz sand filter media?

Under proper use and regular maintenance, the quartz sand filter media can last 1–3 years. If you notice a significant increase in effluent turbidity or a decrease in filtration efficiency, it’s time to partially replace or supplement the filter media.

Can you provide customized quartz sand filters based on our flow rate and size requirements?

Absolutely. We offer fully customized solutions, including flow rate, tank diameter, tank material, and control system, to perfectly match your project’s specific needs.

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, and can operate stably in water with a pH value of 2–13.

What’s the difference between the automatic and manual versions of the filter?

The automatic version uses an intelligent control valve to realize unmanned operation, including timed or pressure-differential backwashing. The manual version requires manual operation of valves for backwashing and filtration, which is more suitable for small-scale applications or scenarios with simple operation needs.
