Definitions
- the present invention relates generally to a water treatment facility and more particularly to a water treatment facility that is portable and securable.
- Dead legs are zones or segments of piping where fluids remain quiescent (limited circulation) either continuously or intermittently. Dead legs are typically defined as dead end piping terminations or cavities that are longer than six (6) pipe diameters from the active piping.

Abstract
A method for providing a water treatment system for a dialysis clinic includes fabricating a portable water treatment system at a first location away from the dialysis clinic, moving the portable water treatment system from the first location to the dialysis clinic, connecting the portable water treatment system to a source of water, and connecting the portable water treatment system to loop piping for circulating treated water to a plurality of dialysis machines of the clinic.
Description
- The present invention relates generally to a water treatment facility and more particularly to a water treatment facility that is portable and securable.
- It will be appreciated by those skilled in the art that water treatment facilities are needed in various fields. One key field is in hemodialysis. Simply put, hemodialysis aids a patient whose body is incapable of filtering the blood. At hemodialysis centers, the prior art has used stationary and fixtured facilities to filter the water necessary to the purity necessary for hemodialysis machines. These water treatment facilities typically consume 400 square feet or more of clinic space. These facilities are attached as fixtures and become permanent parts of the building. Unfortunately, these water treatment facilities are typically located in unsecured spaces with no measures to prevent tampering.
- The fact that these water treatment facilities are fixtures means that once placed into a hemodialysis center, they can not be easily removed. Additionally, from a tax consequence, these items are treated as fixtures as opposed to personal property.
- Because of the sheer size of the systems and the manner in which they have been piped, if an element goes out, the system can have a significant down time.
- Additionally, the sheer size of these systems creates large areas for bacteria growth and the potential for “dead legs.” Dead legs are zones or segments of piping where fluids remain quiescent (limited circulation) either continuously or intermittently. Dead legs are typically defined as dead end piping terminations or cavities that are longer than six (6) pipe diameters from the active piping. Dead legs can provide locations for bacteria to breed, increasing the concentration of pyrogens and endotoxins in the water supply. Additionally, current systems are assembled using solvent welded joints which require special assembly, cleaning and flushing procedures.
- Smaller, portable systems have been described. However, these systems are not designed for use in a dialysis clinic, where a volume of water must be purified sufficiently to be used in multiple dialysis machines. U.S. Pat. No. 5,591,344 to Kenley, et al., describes a portable reverse osmosis system for use in a home or a room in a convalescent center. The system is part of a portable dialysis unit, and is made of components which can withstand heat disinfection. Hot and cold water are mixed to a temperature appropriate for use in a dialysis machine. Sensors detect abnormalities in the system, and operation is described on a visual display with touch screen. However, the system described consists of two subunits—a water pretreatment subunit fitted under a bathroom or kitchen sink, and a water treatment subunit which comprises part of the portable dialysis machine module. Sampling ports are described, but these ports are located at various points within the system, and samples must be taken using a syringe in order to avoid contaminating the system. Sampling is not done from a single location, where ports are accessible from outside the system, while other components remain inaccessible and resistant to tampering. The system must be exposed for sampling, and therefore potential tampering may occur during the sampling process.
- The system described by of Kenley, et al., also constitutes a system for individual use rather than describing a portable system capable of providing water for a number of dialysis machines within a dialysis clinic.
- U.S. Pat. No. 5,244,579 to Horner, et al., also describes a portable reverse osmosis system for the purification of water. However, this system is designed to purify water to a portable drinking water level and not to a level of purity appropriate for hemodialysis. The system output is described as no more than 20 gallons per minute. Fluid connections between components of the systems described by Horner and Kenley are relatively fixed. At best, they may be heat disinfected, as described by Kenley.
- Previous inventions, such as U.S. Pat. No. 5,480,565 to Levin, et al., have described heat disinfection of dialysis machines or water treatment units. The size or composition of most systems presently in use for dialysis clinics makes heat disinfection difficult and prohibits the use of heat sterilization techniques. A system with removable and replaceable autoclavable components would provide distinct benefits in a health care setting.
- In present systems, fixed pipe and valve configurations require technical operators to follow precise instructions on the turning of flow valves whenever carbon treatment tanks are replaced (typically every 90 days). The complexity and infrequent operation of replacement creates a potential hazard that the setting of valves will permit the changed carbon tanks to be “bypassed,” thereby permitting unsafe levels of chlorine and chloramine to come in contact with patient's blood through artificial kidney dialysis.
- What is needed, then, is a system which eliminates tampering or inadvertent positioning of valves leading to bypass of critical water purifying elements. What is needed is a method and design which prevents the operator from operating the system without carbon treatment. This needed system must provide an outer skin or housing which provides “tamper resistant” packaging which may be monitored for tampering. This needed system must reduce the size of a standard water treatment plant by at least one-third thereby allowing economical use of Teflon®, stainless steel, and other more appropriate heat disinfectable or sterilizable but more expensive materials. This needed system must be mobile and fully modular allowing significant reduction in times for service plus allowing depreciation as personal property. This needed system must provide components which can be heat disinfected or sterilized in addition to conventional chemical disinfection. This needed system must minimize dead legs. This needed system must minimize any inefficiencies of design conversions. This needed system must be designed to reduce factors which favor microbiological growth. This needed system must allow the removal and replacement of certain elements with minimal time and expense. This needed system must allow service while in operation. The needed system must, by design, be manufactured to ensure the quality of the system, the efficiency of the process, the reproducibility of the product, and the security of the system. What is needed is a large scale portable system for relief of dialysis treatment needs in disaster areas or parts of the United States and other countries lacking in quality technical personnel. This system must be capable of being remotely and digitally monitored. This system must provide an audit trail for verifying system operation and quality of product and which is remotely monitored. What is needed is a system which allows for easy substitution or addition of water purifying elements such as ultra filters, ultraviolet disinfection lights, or other purifying elements and allows for the easy configuring of system components in series or parallel to achieve greater process reliability through redundancy, improved water quality, and/or greater flow capacity. This needed system is presently lacking in the prior art.

In the preferred embodiment,housing 12 forms a box. However, any shape can be used that encompasseswater treatment member 16 and makes it tamper resistant if desired.Left side 24 andright side 26 can haveside doors 32. In the preferred embodiment,side door 32 is a sliding aluminum steel frame door havingside door lock 34. In order to access eitherright side 26 orleft side 24,side door 32 can haveside door lock 34 unlocked andside door 32 can be raised.Rear 30 can have any type of door as well as to access the rear components.

In the preferred embodiment,front doors front doors water treatment member 16 without openingdoors sample station 48 is provided so that a technician at any time can get any one of preferably foursample buttons 50 to obtain samples of water prior to and after treatment by the various unit operations. - Referring now to FIG. 2, there is shown generally at16 a block diagram view of the water treatment member of the present invention. As can be seen,
cold water 100 andhot water 102 formingwater source 101 come intowater treatment 16 whilewaste material 104 is removed frommember 16 bydrain 108. Ascold water 100 andhot water 102 come into system, water passes through tempering orwater blending valve 80 which controls the temperature of the combination ofcold water 100 andhot water 102. If the water needs to be hotter, more hot water is added by automatic adjustment of temperingvalve 80. If the water needs to be colder, more cold water is added. After passing through temperingvalve 80, first pressure monitor 82 measures the pressure of the incoming water, first temperature monitor 81 ensures that the right mix ofcold water 100 andhot water 102 is being achieved,first pH monitor 79 monitors pH ofwater source 101, and first flow rate monitor 78 measures flow rate. Pressure regulation orreduction valve 83 assists in ensuring the appropriate water pressure.Mixed water 106 then passes through first pump 84 (optional) to achieve the necessary pressure entering the next section of the system should city water pressure be inadequate. Second pressure monitor 86 (optional) ensures thatpump 84 is creating the right head or pressure on thewater 106.Water 106 then passes throughcartridge filters 88 to sift out particulate matter. Filteredwater pressure gauge 87 measures the water pressure passing out of cartridge filters 88.Sample port 89 is provided to measure the quality of water after being filtered bycartridge filter 88. Filteredwater 107 is then sent intowater softener 90.Soft water monitor 92 then measures soft water pressure. Softwater sampling port 91 then allows user to samplesoftened water 109. Soft water passes through first carbon filter ortank 94′ and then second carbon filter ortank 94″. Carbon filter pressure monitors 97′ and 97″ monitor pressure afterrespective filters 94′ and 94″. Alsocarbon sample port 99 allows user to sample water afterfirst carbon filter 94′ to ensure thatcarbon filter 94′ is working. If not,second filter 94″ will act as a back-up in case carbon filter. 94′ is spent. Carbon filters. 94 filter out organic material and dissolved gases (particularly chlorine and chloramines). Carbonfilter backwash waste 95 passes into drain 104 (optional). Carbon-filteredwater 112 is then sent intopretreatment cartridge filter 114. Water is then pressure monitored at reverse osmosis feed water pressure monitor 116 before passing intoreverse osmosis unit 118. Before passing intocirculation pump 128,RO water 130 passes through permeate pressure monitor 132 and permeateconductivity monitor 134. RO water can be sampled atRO sampling valve 136. Circulatedwater 138 then passes into water input flow monitor 98 before passing into circulatedpressure monitor 140. Circulatedwater 138 then passes intostorage tanks 124 havinglevel indicator monitor 144. Waste water is directed intodrain 108. After passing intowater storage 124, water flows through loop piping 123 intodialysis units 110. In the preferred embodiment,water storage units 124 are sized sufficiently to allow any of the upstream components to be exchanged without having to terminate the flow of liquid intodialysis units 110. - Referring now to FIG. 3, there is shown generally at10 a top view of the portable water treatment facility.
