Disclosed are a system and method for preventing and monitoring a leakage of water from a tank liner at a storage tank having: a concrete reservoir; the tank liner made up of a wall liner that is formed by coupling a plurality of first panels and is attached to an inner wall of the concrete reservoir, and a floor liner that is formed by coupling a plurality of second panels, is attached to a floor of the concrete reservoir, and is coupled to the wall liner by welding; a leaking water collecting plate formed by welding a plurality of third panels and inserted between the floor liner and the floor of the concrete reservoir; and an edge leaking water collecting channel buried in an edge of the storage tank and configured to collect leaking water discharged between the floor liner and the leaking water collecting plate.

A device for emitting bubbles in a vehicle wash facility includes a plenum supported with respect to ground. The plenum includes an air inlet with a first area and an air outlet with a second area. The plenum air outlet is in communication with at least one foaming chamber. The foaming chamber includes a generally planar media element disposed therein. The foaming chamber includes a spray jet located therein, which is in communication with a source of chemical. The spray jet configured to emit a chemical onto the generally planar media element. The device also includes a plurality of nozzle portions in communication with the foaming chamber for emitting bubbles therefrom.

According to one aspect, a manifold assembly includes a skid, a low pressure manifold connected to the skid, and a high pressure manifold connected to the skid. In another aspect, the high pressure manifold has a modular configuration so that the high pressure manifold is disconnectable in whole or in part from the skid, and reconnectable in whole or in part to the skid. In yet another aspect, the high pressure manifold includes high pressure modules, all of which are in fluid communication with each other and each of which is adapted to be in fluid communication with at least one pump. In still yet another aspect, the low pressure manifold includes one or more flow lines, the high pressure manifold includes fittings, and the manifold assembly includes vibration isolators to dampen dynamic loading, the vibration isolators being disposed between the fittings and the one or more flow lines.

A surgical boom having a surgical head with an electrical connection, a plurality of inlet ports, a compressed gas outlet, and a water outlet, one of the inlet ports having a cover, a hollow surgical arm mounted to a ceiling in a room and having a plurality of joints, a shaft passing through said ceiling, and a shaft collar attached to the ceiling, an outlet port, a filter media arranged between said outlet port and one of the inlet ports, the filter media comprising an ULPA media and an adsorbent layer, a control panel, a suction unit configured and arranged in a position below the ceiling to cause a fluid to be drawn from the inlet port through the filter media and out through said outlet port while minimizing noise in the proximity of the inlet port, wherein the fluid drawn from said inlet port comprises an exhaust path through the hollow arm.
