Energy-Efficient Quartz Sand Filter - Fast Backwash & Low Water Waste

Our Quartz Sand Filter is an advanced, cost-effective depth filtration system specifically designed for industrial water pretreatment and purification. Using high-purity graded quartz sand with precise particle control as the core filter medium, it effectively traps suspended particles, sediment, colloidal contaminants, algae, and certain organic impurities from water under steady pressure. As a key pre-treatment component for reverse osmosis (RO), ultrafiltration (UF), and other advanced water treatment systems, it protects downstream equipment from fouling and damage, extends their operational life, and helps businesses reduce long-term maintenance and operational costs.

Technical Features

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

Dual control options: automatic control for unattended operation and manual control for flexible adjustment, covering all filtration, backwashing, and drainage procedures smoothly.

Versatile tank material choices: FRP, Carbon Steel Lined Rubber, SS304, and SS316L, capable of withstanding corrosive environments and adapting to diverse water quality conditions.

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

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

Compact design with small footprint, easy installation and commissioning, saving on-site space and reducing setup time.

FAQ

How often do I need to backwash the quartz sand filter?Backwashing is recommended when the filter’s pressure difference reaches 0.05–0.07MPa. Normally, 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 use and regular maintenance, the quartz sand filter media can last 1 to 3 years. If effluent turbidity increases notably or filtration efficiency declines, you need to partially replace or replenish the filter media.

Can you customize quartz sand filters according to our 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 meet your project’s unique needs.

Is this quartz sand filter compatible with acidic or alkaline water sources?Certainly. 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 difference between the automatic and manual filter versions?The automatic version comes 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 suitable for small-scale applications or simple operational needs.
