Delivery Case of Reach Filter - Sand Filtration System for a Major Gas Company in Chiba Prefecture

Applicable to high SS concentration wastewater with extremely high filtration efficiency! Introducing case studies of filtration equipment.

At a major gas company in Chiba Prefecture, the concentration of reducing water varies by area; in low-concentration areas, it is a few mg/L, while in high-concentration areas, it can reach up to 80 mg/L. Conventional sand filtration systems were applied to brine with SS concentrations of approximately 30 mg/L or lower. However, in brine with high SS concentrations, the filter bed became clogged within a short period (a few months), leading to an inability to continue operation (due to insufficient cleaning power). In this situation, by adopting the "Reach Filter," which has a very high filter bed cleaning efficiency, it became completely applicable to brine with high SS concentrations and has been adopted in other high SS concentration areas as needed. [Case Study] ■ Location: Major gas company in Chiba Prefecture ■ Application: Purification of brine in water-soluble gas fields ■ Purpose of filtration: To suppress ground subsidence and maintain the reducing capacity of reducing wells by removing SS from brine ■ Type of raw water: Brine ■ Model and processing capacity: RFE-2000 and others ■ Filter media used: Silica sand *For more details, please refer to the PDF document or feel free to contact us.
