The combination of multi-media filter and ultrafiltration (UF) equipment typically delivers superior performance, as the two units form a complementary system of “pretreatment system + deep filtration”, significantly enhancing overall water treatment efficiency and effluent quality.
The core value of this combination lies in functional complementarity, rather than a simple series connection. The multi-media filter, as a pretreatment system, resolves the critical pain points of the ultrafiltration (UF) system; the UF equipment then achieves deeper purification on this basis.
The core advantage of the combined system lies in protecting the UF membrane and extending its service life. The multi-media filter removes suspended solids, sediment, and large particulate impurities from the raw water, preventing these substances from clogging the UF membrane pores, thereby reducing cleaning frequency and minimizing membrane degradation.
To enhance the operational efficiency of ultrafiltration (UF) systems, pretreatment reduces the turbidity and pollutant load of the raw water. This allows the UF membrane to focus on retaining fine impurities such as colloids, bacteria, and macromolecular organics, thereby preventing the decline in water production performance caused by excessive fouling load.
To ensure stable final effluent quality, the multi-media filter performs“coarse filtration”to control large particulate contaminants, while the ultrafiltration (UF) unit conducts “polishing filtration”to capture fine impurities. This dual-stage filtration effectively reduces the pollutant concentration in the effluent, making it particularly suitable for applications with stringent water quality requirements, such as drinking water production and industrial process water.
Typical Application Scenario—Advanced Treatment of Municipal Tap Water (e.g., direct drinking water production): The multi-media filter removes sediment and suspended solids from the pipeline network, while the ultrafiltration (UF) system further retains residual chlorine, bacteria, and other fine contaminants, thereby enhancing water safety and quality.
Wastewater treatment and reuse: The multi-media filter (MMF) removes suspended solids (SS) from the secondary effluent (biochemical effluent), and the ultrafiltration (UF) system subsequently performs advanced treatment, providing a qualified water source for downstream reuse applications such as irrigation and cooling water.
