Ultra – Dewatering Bag Oil & Sediment (4.5mL x 3mW) 250mm neck on corner

SHS-CHU9725 Ultra-Dewatering Bag – Oil and Sediment (4.5m x 3m) 250mm Neck

Extra-Large-Capacity Dual-Purpose Filtration for Oil & Sediment Control in Major Dewatering Operations

Overview

The CHU9725 Ultra-Dewatering Bag is an extra-large-capacity, specialized filtration solution engineered to capture both oil-based contaminants and suspended sediments during major dewatering operations. Measuring 4.5 metres in length and 3 metres in width, this dual-purpose bag provides massive 4m³ sediment capacity for effective control of hydrocarbons and solids on large-scale construction, industrial, mining, and environmental sites where both pollutants are present in high volumes.

Constructed from 270gsm non-woven geotextile fabric with advanced oil-absorbing properties, the bag allows water to pass through while retaining oils, hydrocarbons, silt, and suspended solids with 99.0% filter efficiency. The integrated 250mm diameter neck, positioned on the short side/top of the bag, ensures easy connection to large-diameter discharge hoses for efficient and secure operation in high-volume applications.
