Abstract: The present invention is a flexible, fillable and/or inflatable breach bag (aqua ram) with a planar body and at least one fillable water chamber for use in breaching locked or barricaded doors or penetrating surfaces with explosive charges. The breach bag may conform to a variety of shapes, depending on the application. The bag generally includes a generally planar panel of flexible material and at least one water chamber disposed on the material layer with a fluid inlet for the selective introduction of fill material, generally in the field. Additionally, the bags include means to suspend the breach bag against structures to be breached.

Abstract: The present invention is a flexible, fillable and/or inflatable breach bag with a planar body and at least one fillable bladder for use in breaching locked or barricaded doors or penetrating surfaces with explosive charges. The breach bag may conform to a variety of shapes, depending on the application. The bag generally includes a panel of flexible material having at least two material layers, including a plurality of seams joining at least two of the material layers to form at least one bladder between the material layers for the selective of fill material, generally in the field. The bladders include fluid inlets providing fluid access to said bladder for filling said bladder with fill material. Additionally, the bags include means to suspend the breach bag against structures to be breached.

Abstract: A method of controlling the amount of conductivity increasing substances, e.g., free available halogen, in particular free available chlorine, present in an aqueous medium is described. In accordance with the method of the present invention, an aqueous medium is provided and its conductivity determined. A source of at least one conductivity increasing substance is introduced controllably into the aqueous medium, and a second conductivity measurement is made. The determined conductivities are compared, and in response to this comparison, the amount of conductivity increasing substance added to the aqueous medium is adjusted. In a preferred embodiment of the present invention, the aqueous medium is an aqueous stream, and the source of conductivity increasing substance is calcium hypochlorite, which is introduced into the aqueous stream through the use of a feeder unit, i.e., a chlorination unit.
