Reliable Industrial Quartz Sand Filter - 5+ Years Uninterrupted Operation

Our Quartz Sand Filter is a high-performance, industrial-grade depth filtration system specially designed for water pretreatment and purification in industrial scenarios. With high-purity graded quartz sand (subjected to strict particle size inspection) as the core filter medium, it can effectively capture suspended particles, sediment, colloidal contaminants, algae, and some organic impurities in water under stable pressure. As an essential pre-treatment device for reverse osmosis (RO), ultrafiltration (UF), and other advanced water treatment systems, it protects downstream equipment from scaling and contamination, extends their service life, and helps enterprises reduce long-term operational and maintenance costs.

Technical Features

Adopts high-purity graded quartz sand filter media with strict particle size inspection, featuring uniform particle distribution, strong adsorption capacity, and reliable filtration performance.

Two control modes are provided: automatic control for unattended 24/7 operation and manual control for flexible adjustment, which can smoothly cover filtration, backwashing, and drainage processes.

Various tank material options are available: FRP, Carbon Steel Lined Rubber, SS304, and SS316L, all of which can resist harsh corrosive environments and adapt to different water quality conditions.

Equipped with an efficient backwashing system: 5–7 minutes rapid backwash cycle,low water waste, 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 maintained at ≤5NTU.

Compact structure and small floor space, easy to install and commission, which can save on-site construction space and shorten the installation cycle.

Key Advantages

High Filtration Efficiency: Removes more than 95% of suspended solids in water, stably reduces water turbidity, and provides high-quality water for subsequent advanced treatment.

Economical Operation: 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 a pH range of 2–13, suitable for various industrial water scenarios and different types of water sources.

Durable and Reliable: The anti-corrosion tank structure combined with high-quality components ensures stable operation for more than 5 years, minimizing equipment downtime and replacement costs.

Highly Customizable: According to the specific needs of your project, we can customize the flow rate, tank size, control mode and tank material to achieve perfect matching.

FAQ

What is the proper backwashing frequency for the quartz sand filter?Backwashing is recommended when the pressure difference of the filter reaches 0.05–0.07MPa. Generally, this occurs 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?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 offer 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.
