Abstract: A bioremediation device (10) for degrading hydrocarbons on components, the bioremediation device having a housing (18), a basin (28) partially seating within the housing with the basin (28) including an upper condensation chamber (39) to permit vapour from a lower basin portion (35) to enter and to condense to be returned to the lower basin portion (37). A control module (46) is immersed in the lower basin portion (37) and has a heater (52), a pump (56,76), a filter (74) and a valve (58) for directing fluid either to the filter (74) or to an aeration device (44).

Abstract: The invention provides a staircase arrangement for use within a swimming pool. The staircase arrangement comprises a staircase and at least one suction device. The staircase includes a set of stairs, a bottom-facing surface and a wall-facing surface. Each of the at least one suction devices comprises an attachment portion for attachment to at least one of the bottom-facing surface and the wall-facing surface of the staircase and a suction portion suitable for establishing a suction connection with an interior surface of the swimming pool so as to secure the staircase to the interior surface of the swimming pool.

Abstract: A stair portion for a stair assembly for a swimming pool, comprising a bottomless hollow body having lateral surfaces and a top surface defining steps. The bottomless hollow body is adapted to be received in a pool with bottom edges of the lateral surface lying against a bottom of the pool such that a user person can move in or out of the pool using the steps. The bottomless hollow body is adapted to be connected to a pool connector portion for being secured adjacent to a sidewall of the pool. The bottomless hollow body is adapted to be nested with another bottomless hollow body, so as to facilitate transportation, warehouse storage or maneuverability in a body of water.
