DOCUMENTATION CONVENTIONS This uses the following conventions to present information: An exclamation point icon indicates a WARNING of a situation or condition that could lead to personal injury or death. You should not proceed until you read and thoroughly understand the WARNING message.
This screen is specially treated to pass oil and repel water. The screen is therefore termed oleophilic/hydrophobic (oil loving /water hating). The Geotech Filter Bucket comes with a standard 100 mesh intake screen. A 60 mesh intake screen is also available for use with higher viscosity fluids. See Geotech Manual “Hydrocarbon Viscosity Test Kit”...
Section 2: System Installation The Geotech Filter Bucket is placed in a sump, pond, or other body of water. It is easily deployed by holding the circumferential handle. The bucket and cartridge will float as shown in Figure 3-1. As it progressively fills, the bucket will sink into the water while the cartridge will remain at the water/product interface (Figure 3-3).
When the cover of the bucket is removed, product can be seen flowing into the bucket. The rate of flow into the Filter Bucket is dependent upon the viscosity of the product and the thickness of the slick (See Section 6: System Specifications).
Cleaning the Intake Screen and Filter Bucket The Geotech Filter Bucket will come with a floating cartridge containing a 100 or 60 mesh intake screen. When required, gently clean the screen with WD40 or kerosene, using a soft, bristle brush, to remove emulsified product, bio growth or other debris.
Section 5: System Troubleshooting If the Filter Bucket fails to perform properly, check for the following: Visually inspect the Filter Bucket for damage, such as loose fittings, cut hose, or cracks or splits in the reservoir. Verify that the intake screen is not clogged and can move up and down freely.
Detergent or surfactant concentrations greater than 100 ppm (grams/liter) may cause the cartridge to pass water. Also, if the Filter Bucket is placed in an area with no product to “wet” the screen, a natural biological film will coat the screen and reduce its ability to repel water. Since this biological build-up (or fouling) is accelerated by warm temperatures, the cartridge will pass water more easily during the summer or in tropical environments.

Product Type Recovered The Filter Bucket will recover any non-polar liquid with a density less than water. This leaves out such dense materials as chloroform, carbon disulfide, carbon tetra-chloride and Freon.
Appendix A: Decontamination Procedures Some common decontamination solutions are listed below along with the contaminants they are effective against: Solution Effective Against Water Short-chain hydrocarbons, inorganic compounds, salts, some organic acids, other polar compounds. Dilute Acids Basic (caustic or alkaline) compounds, amines, hydrazines. Dilute Bases Acidic compounds, phenols thiols, some nitro- and sulfonic compounds.

detergent Decontamination Solutions to Avoid Some decontamination solutions should be avoided because of their toxicity, flammability, or harmful effects to the environment. Halogenated hydrocarbons, such as carbon tetrachloride, should not be used because of their toxicity, possible incompatibility, and some because of their flammability. Organic decontamination solutions should not be used on Personal Protective Equipment (PPE) because they may degrade the rubber or other materials comprising the PPE.

Disposal collection containers, such as drums or suitably lined trash cans for disposable clothing and heavily contaminated personal protective clothing or equipment to be discarded. Lined box with adsorbent for wiping or rinsing off gross contaminants and liquid contaminants.
