Ultra – Dewatering Bag Oil & Sediment (1.2mL x 0.9mW) 250mm neck on the corner

SHS-CHU9729 Ultra-Dewatering Bag – Oil and Sediment (1.2m x 0.9m) 250mm Neck

Dual-Purpose Filtration for Oil & Sediment Control in Dewatering Applications

Overview

The CHU9729 Ultra-Dewatering Bag is a specialized filtration solution engineered to capture both oil-based contaminants and suspended sediments during dewatering operations. Measuring 1.2 metres in length and 0.9 metres in width, this dual-purpose bag provides effective control of hydrocarbons and solids on construction, industrial, and environmental sites where both pollutants are present.

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.

Key Features & Benefits

Dual-Purpose Filtration
Specifically designed to capture both oil-based contaminants and suspended sediments in a single solution.

High-Efficiency Contaminant Removal
