Abstract: The present invention relates to a fluid treatment system, more particularly an ultraviolet radiation water treatment system, comprising: an inlet (112); an outlet (124); and a fluid treatment zone (120) disposed between the inlet and the outlet. The fluid treatment zone has disposed therein: (i) a first bank (126) of elongate radiation source assemblies having a first longitudinal axis, and (ii) a second bank (128) of elongate radiation source assemblies having a second longitudinal axis. The first longitudinal axis and the second longitudinal axis are non-parallel to each other and oblique to a direction of fluid flow through the fluid treatment zone. The present fluid treatment system has a number of advantages including: it can treat large volumes of fluid (e.g., wastewater, drinking water or the like); it requires a relatively small "footprint"; it results in a relatively lower coefficient of drag resulting in an improved hydraulic pressure loss/gradient over the length of the fluid treatment system; and it results in relatively lower (or no) forced oscillation of the radiation sources thereby obviating or mitigating of breakage of the radiation source and/or protective sleeve (if present).

Other advantages are discussed in the specification.

Abstract: There is described a novel fluid level control system, particularly useful f or controlling the level of water flowing in an open channel. The fluid level control system comprises a gate having a flap portion (3) interconnected to a lever portion (5). The flap portion is rotatable about a first pivot point ( 8) and comprises a first weight. The system further comprises a frame (1) which is fixed with respect to the flap portion. A linkage (11, 12, 13) interconnects the flap portion and the lever portion, and is connected to th e frame at a second pivot point (10) different than the first pivot point (8). Under changing flow conditions in the channel, the present system operates b y both : absolute movement of the lever portion and the flap portion, and (ii) relative movement between the lever portion and the flap portion. A fluid treatment system comprising the fluid level control system and a method for controlling the level of a flowing fluid are also described.

Abstract: A fluid level control system, particularly useful for controlling the level of water flowing in an open channel. The fluid level control system includes a gate having a flap portion interconnected to a lever portion. The flap portion is rotatable about a first pivot point. The system further includes a frame which is fixed with respect to the flap portion. A linkage interconnects the flap portion and the lever portion, and is connected to the frame at a second pivot point different than the first pivot point. Under changing flow conditions in the channel, the present system operates by both: (i) absolute movement of the lever portion and the flap portion, and (ii) relative movement between the lever portion and the flap portion. A fluid treatment system and a method for controlling the level of a flowing fluid may also use such a fluid level control system.
