The present disclosure is related to a water recycling system. In particular, the present disclosure is related to a monitored water recycling system and a method of determining and providing real time water savings and/or water usage information.
As shown in
The washing solution is transported from the tank 10 by at least one pump 40. Additional pumps 40 may be provided depending on the particular operating requirements. For example, 1 to 10 pumps 40 may be provided. The pumps 40 transport the washing solution from the tank 10 to an operation 20a, 20b, 20c . . . 20n. The pumps 40 are not particularly limited and may be, for example, an air diaphragm pump, an electric pump, or the like.
The operations 20a, 20b, 20c . . . 20n are not particularly limited and may be any operation wherein filtering and recycling is required or desired. Although operations 20a, 20b, 20c . . . 20n are shown, the system 1 may include a single operation, 2 operations, 3 operations, or 4 or more operations. For instance, the operations 20a, 20b, 20c . . . 20n may include a washing station, for example, one or more inside outside bird washers (IOBW). In some embodiments, the operations 20a, 20b, 20c . . . 20n may include a chiller system or a dip tank. The flow rate and pressure employed in the operations 20a, 20b, 20c . . . 20n is not particularly limited and may be specified based on particular operating requirements.
After the washing solution has been utilized in the operations 20a, 20b, 20c . . . 20n, the spent washing solution flows through drains 70a, 70b, 70c . . . 70n to at least one filtering assembly 30 to recover a recycled solution. To facilitate flow from the drains 70a, 70b, 70c . . . 70n to the filtering assembly 30, a pump 42 may be employed. The pump 42 is not particularly limited and may be, for example, an air diaphragm pump, an electric pump, or the like. In one or more embodiments, a plurality of pumps 42 may be employed. For example, a separate pump 42 may be associated with each of 20a, 20b, 20c . . . 20n. The recycled solution may be directed back into tank 10 (i.e., re-used as washing solution) or may be diverted to a secondary storage container (not shown) for alternative uses.
The filtering assembly 30 may include, for example, a rotary screen. In such cases, a spray bar line 12 may supply additional solution to the rotary screen (filtering assembly 30) in order to wash the rotary screen. The additional solution may include, for example, fresh water, a solution (e.g., an antimicrobial solution), or the recycled solution recovered from the filtering assembly 30. The rate of flow through the spray bar line 12 is not particularly limited, and may be, for example, from 0 gallon per minute (gpm) to 60 gpm, from 60 gpm to 100 gpm, from 100 to 160 gpm, from 1 gpm to 200 gpm, from 5 gpm to 100 gpm, or from 10 gpm to 50 gpm.
One or more secondary filtering assemblies 31 may be employed as needed throughout the system 1. The secondary filtering assembly 31 may, for example, include an inline filter, such as a bag filter, between the tank 10 and the operations 20a, 20b, 20c . . . 20n. Depending on operating requirements, the filtering assemblies 30, 31 may be configured to filter out particles greater than 1 mm, greater than 900 μm, greater than 800 μm, greater than 700 μm, greater than 600 μm, greater than 500 μm, greater than 400 μm, greater than 300 μm, greater than 200 μm, or greater than 100 μm. For instance, the filtering assembly 30 or 31 may include a mesh having pores of any of the foregoing sizes. If the washing solution includes large particles, spray nozzles (not shown) used throughout the system 1 (e.g., used to spray the rotary screen or used in the operation 20) may become clogged. Additionally, filters that are too fine may require more frequent maintenance. As such, the filtering assemblies 30, 31 and nozzle sizes may be appropriately adjusted to suit the operational needs.
In one or more embodiments, a volume of washing solution in the tank 10 is maintained at a constant level. This may be achieved by, for example, adjusting the amount of fresh water supplied by incoming water line 11. The rate of flow through the incoming water line 11 is not particularly limited, and may be, for example, from 0 gpm to 1000 gpm, from 10 gpm to 500 gpm, or 60 gpm to 250 gpm. The flow rate through incoming water line 11 may be constant or variable. For instance, if a known amount of liquid is lost through the washing operation, the flow rate may be adjusted appropriately to offset such loss. In some embodiments, the flow rate may be adjusted to overflow the tank 10 thereby refreshing the washing solution. Alternatively, the flow rate may be manually or automatically varied based on the observed volume in the tank 10. Optionally, the tank 10 may include a sensor 80, such as a transducer, in order to monitor the volume of washing solution therein. The sensor 80 may also measure other properties of the liquid in the tank 10, such as the salinity, acidity, temperature, viscosity, and the like. The system 1 may include additional components as needed, for example, a high voltage panel 60 and a control panel 50.
The system 1 includes at least one meter to measure a flow rate or volume of solution within the system 1. In some embodiments, each inlet line includes a meter to provide a measurement of total volume or rate of liquid supplied to the system 1 (“supplied water volume/rate”). Namely, incoming water line 11 includes a meter 91 and, optionally, spray bar line 12 and chemical injection line 13 include meters 92 and 93, respectively. In any embodiment, a plurality of incoming water lines 11, a plurality of spray bar lines 12, and/or a plurality of chemical injection lines 13 may be included in the system, each including meters 91, meters 92, and/or meters 93, respectively. Additionally, the system 1 may include at least one meter between the tank 10 and the operations 20a, 20b, 20c . . . 20n. For instance, meters 90a, 90b, 90c . . . 90n may be supplied either before or after each operation 20a, 20b, 20c . . . 20n to obtain a measurement of a total liquid volume or rate utilized in the system 1 (“used water volume/rate”). In some embodiments, meters 90a, 90b, 90c . . . 90n are provided between the tank 10 and the operations 20a, 20b, 20c . . . 20n, such as before the washing operation in order achieve an accurate measurement of used volume (or usage rate), as some volume of liquid is likely to be lost during the washing. In one or more embodiments, a single meter 90a may be used with a plurality of operations 20a, 20b, 20c . . . 20n. For example, the single meter 90a may measure the rate or volume of a liquid passing through a communal line which subsequently splits to supply liquid to the plurality of operations 20a, 20b, 20c . . . 20n. In one or more embodiments, the meters 90a, 90b, 90c . . . 90n may be provided within the operations 20a, 20b, 20c . . . 20n. The meters 90a, 90b, 90c . . . 90n relay the collected information to a processor, which can then calculate a water savings value by subtracting the supplied volume or rate from the used volume or rate, as discussed in detail below.
