Multilayered bladder and carbon scrubber for storage tank
View Patent ↗An apparatus and method for collection and containment of collected materials is provided. The apparatus can include a vacuum truck with at least one vacuum tank disposed thereon, the vacuum tank having a hollow interior region. A flexible bladder can be disposed within the hollow interior region of the vacuum tank. The bladder can be impermeable to and compatible with the collected material and capable of containing the material therewithin.
1. An apparatus for containment of collected materials, the apparatus comprising:
at least one storage tank, the storage tank having a hollow interior region;
a multilayered bladder disposed within the hollow interior region, the bladder being operable to contain the material therewithin, the bladder comprising a single barrier layer that is impervious to permeation by the collected materials and at least a pair of wear layer that are resistant to tearing, the single barrier layer being disposed between the wear layers and contacting the wear layers, and wherein at least one of the wear layers is coated with an anti-static material;
at least one opening formed in the bladder to allow the materials to enter or exit the bladder;
an access port disposed on the storage tank and accessible to the hollow interior region of the tank; and
a vacuum pump attachable to the access port and operable to regulate the pressure of the hollow interior region of the tank, external to the bladder.
2. The apparatus of claim 1 , wherein the vacuum pump is operable to pull a vacuum on the hollow interior region of the tank, external to the bladder.
3. The apparatus of claim 1 , wherein the vacuum pump is operable to pressurize or depressurize the hollow interior region of the tank, external to the bladder.
4. The apparatus of claim 1 , wherein the bladder is impermeable to and compatible with the material.
5. The apparatus of claim 1 , wherein the bladder is deflated when the vacuum pump pressurizes the hollow interior region of the tank, external to the bladder.
6. The apparatus of claim 1 , wherein the bladder is inflated when the vacuum pump depressurizes the hollow interior region of the tank, external to the bladder.
7. The apparatus of claim 1 , whereby the barrier layer contacts the wear layers.
8. The apparatus of claim 1 , wherein the storage tank is disposed on a vacuum truck.
9. The apparatus of claim 1 , further comprising one or more carbon scrubbers disposed on an exhaust of the vacuum pump to absorb collected materials from the exhaust.
10. The apparatus of claim 1 , wherein the single barrier layer is formed of polytetrafluoroethylene.
