Product parameter:
Our Quartz Sand Filter is a high-reliability, efficient depth filtration system specially developed for industrial water pretreatment and purification. Made with high-purity graded quartz sand (with strict particle size screening) as the core filter medium, it can effectively trap suspended particles, sediment, colloidal impurities, algae, and some organic pollutants in water under stable pressure. As a key pre-treatment equipment for reverse osmosis (RO), ultrafiltration (UF), and other advanced water treatment systems, it protects downstream equipment from contamination, prolongs their service life, and helps enterprises reduce long-term operation and maintenance costs.
Technical Features
Adopts high-purity graded quartz sand filter media, with uniform particle size, strong adsorption capacity, and stable filtration effect.
Two control modes are available: automatic control for unattended operation and manual control for flexible adjustment, which can seamlessly cover filtration, backwashing, and drainage processes.
Various tank material options: FRP, Carbon Steel Lined Rubber, SS304, and SS316L, which can resist harsh corrosive environments and adapt to different water quality conditions.
Efficient backwashing system: 5–7 minutes fast backwash cycle, low water consumption, and supports continuous online operation without affecting normal water supply.
Stable operating performance: working pressure is 0.05–0.6MPa, filtration rate is 5–12m/h (maximum 15m/h), and effluent turbidity is stably controlled below 5NTU.
Compact structure and small floor space, easy to install and commission, which can save on-site construction space and shorten installation time.
Key Advantages
Excellent Filtration Efficiency: It can remove more than 95% of suspended solids in water, stably reduce water turbidity, and provide high-quality water sources for subsequent treatment.
Economical and Practical: Low energy consumption, long service life of filter media, and simple maintenance process, which can effectively reduce the long-term operation cost of users.
Strong Adaptability: It can operate stably in water with pH value of 2–13, suitable for various industrial water scenarios and different types of water sources.
Durable and Reliable: The anti-corrosion tank design combined with high-quality components ensures stable operation for more than 5 years, reducing equipment downtime and replacement costs.
High Customization: According to the actual needs of your project, we can customize the flow rate, tank size, control mode and tank material to meet your specific requirements.

FAQ
What is the appropriate backwashing frequency for the quartz sand filter?Backwashing is recommended when the pressure difference of the filter reaches 0.05–0.07MPa. Generally, this happens every 1 to 7 days, depending on the turbidity and impurity content of the incoming water.
How long can the quartz sand filter media be used before replacement?With proper use and regular maintenance, the quartz sand filter media can be used for 1 to 3 years. If the effluent turbidity increases significantly or the filtration efficiency decreases, it is necessary to partially replace or supplement the filter media.
Can you provide customized quartz sand filters according to our flow rate and size requirements?Yes, we can. We provide fully customized solutions, which can adjust the flow rate, tank diameter, tank material and control system to perfectly match the actual needs of your project.
Is this quartz sand filter suitable for acidic or alkaline water sources?Of course. Our filters with FRP or stainless steel (SS304/316L) tanks have excellent acid and alkali resistance, and can operate stably in water with pH value of 2–13.
What is the difference between the automatic and manual versions of this filter?The automatic version is equipped with an intelligent control valve to realize unattended operation, including timed or pressure-difference backwashing. The manual version needs to manually operate the valve for backwashing and filtration, which is more suitable for small-scale applications or simple operation scenarios.
