Food-Safe Quartz Sand Filter | For Electronics, Pharma & Beverage

Our Quartz Sand Filter is a professional-grade, cost-effective depth filtration system designed exclusively for industrial water pretreatment and purification. Featuring precision-graded high-purity quartz sand (under strict particle size control) as its core filter medium, it efficiently captures suspended particles, sediment, colloidal contaminants, algae, and certain organic pollutants in water under stable pressure. As an indispensable pre-treatment component for reverse osmosis (RO), ultrafiltration (UF), and other advanced water treatment systems, it protects downstream equipment from fouling, extends their service life, and helps enterprises cut down long-term operational and maintenance costs.

Technical Features

Features precision-graded high-purity quartz sand filter media, boasting uniform particle size, strong adsorption capacity, and consistent filtration performance.

Offers two control modes: automatic control for unattended operation and manual control for flexible adjustment, seamlessly covering all filtration, backwashing, and drainage processes.

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

Equipped with an efficient backwashing system: 5–7 minutes rapid backwash cycle, low water consumption, 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 below 5NTU.

Boasts a compact structure with a small footprint, easy installation and commissioning, saving on-site construction space and shortening the overall setup period.

Key Advantages

FAQ

How often should I perform backwashing on the quartz sand filter?Backwashing is recommended when the filter’s pressure difference reaches 0.05–0.07MPa. Usually, this occurs every 1 to 7 days, depending on the turbidity and impurity content 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 serve for 1 to 3 years. If effluent turbidity increases significantly or filtration efficiency drops, partial replacement or replenishment of the filter media is needed.

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

Is this quartz sand filter compatible with acidic or alkaline water sources?Yes, it is. Our filters with FRP or stainless steel (SS304/316L) tanks have excellent 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 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 more suitable for small-scale applications or simple operational scenarios.
