A fluid treatment system having an inlet, an outlet, and a fluid treatment zone therebetween. The zone has an array of rows of radiation source assemblies. Each radiation source assembly has a longitudinal axis disposed at an oblique angle with respect to a direction of fluid flow. Each row has a plurality of radiation source assemblies in spaced relation in a direction transverse to the direction of fluid flow, to define a gap through which fluid may flow between an adjacent pair of assemblies. Preferably, all rows in the array are staggered with respect to one another in a direction orthogonal to the direction of fluid flow, such that the gap between an adjacent pair of radiation source assemblies in an upstream row of assemblies is partially or completely obstructed in the direction of fluid flow by a serially disposed radiation source assembly in at least one downstream row.

Fluid treatment system

A fluid treatment system having: an inlet; an outlet; and a fluid treatment zone disposed therebetween. The fluid treatment zone has: (i) an elongate first radiation source assembly having a first longitudinal axis, and (ii) an elongate second radiation source assembly having a second longitudinal axis. The first and second longitudinal axes are non-parallel to each other and to a direction of fluid flow through the treatment zone. The present fluid treatment system 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 treatment system; and it results in relatively lower (or no) forced oscillation of the radiation sources thereby mitigating breakage of the radiation source and/or protective sleeve (if present).

The present invention relates to a fluid treatment system comprising: an inlet; an outlet; and a fluid treatment zone disposed between the inlet and the outlet. The fluid treatment zone has disposed therein: (i) an elongate first radiation source assembly having a first longitudinal axis, and (ii) an elongate second radiation source assembly having a second longitudinal axis. The first longitudinal axis and the second longitudinal axis are non-parallel to each other and 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.

An online device and method for predicting at least one fluid flow parameter in a process (which comprises a bounded flow domain having disposed therein a pre-determined matrix) includes a computer and/or process steps whereby: (i) a memory receives a database, the database comprising location information for a plurality of nodes or particle pathways in the matrix; (ii) input data is received from the process, and (iii) the at least one fluid flow parameter is calculated from the database and the input data. Preferably, structure and/or process steps are provided to adjust the database in the event that the input data does not correspond with at least one pre-determined flow state.

On-line device for predicting at least one fluid flow parameter in a process

An on-line device for predicting at least one fluid flow parameter in a process includes structure and/or function whereby a flow domain has disposed therein a pre-determined portion in which a fluid flows. Preferably, the device includes a computer having: (i) a memory for receiving a database, the database including relative information in respect of a plurality of nodes or a plurality of particle pathways in the pre-determined portion; (ii) structure to receive input data from the process, and (iii) structure to calculate the at least one fluid flow parameter from the database and the input data. The device is particularly advantageously employed as a UV dosimeter.

A fluid treatment device, particularly useful for ultraviolet radiation treatment of fluids such as water. The device comprises a housing for receiving a flow of fluid. The housing has a fluid inlet, a fluid outlet, a fluid treatment zone disposed between the fluid inlet and the fluid outlet and at least one radiation source having a longitudinal axis disposed in the fluid treatment zone substantially transverse to a direction of the flow of fluid through the housing. The fluid inlet, the fluid outlet and the fluid treatment zone are arranged substantially collinearly with respect to one another. The fluid inlet has a first opening having: (i) a cross-sectional area less than a cross-sectional area of the fluid treatment zone, and (ii) a largest diameter substantially parallel to the longitudinal axis of the at least one radiation source assembly.
