  • Patent number: 9862624
    Abstract: A transformational approach to water treatment is provided that incorporates membrane-free filtration with dynamic processing of the fluid to significantly reduce treatment times, chemical cost, land use, and operational overhead. This approach provides hybrid capabilities of filtration, together with chemical treatment, as the water is transported through various spiral stages.
    Type: Grant

  • Patent number: 9067803
    Abstract: Provided is a standalone integrated water treatment system for a distributed water supply including a filter input, a coagulation system in operative connection with the filter input, wherein the water is subjected to a coagulation process to create pin floc from suspensions in the water. A maturation buffer tank in operative connection with the coagulation system aggregates floc in size within the water. A spiral separator separates the water into two water streams, a first stream of water having most of the floc removed, and a second stream of water which includes a concentrated amount of the floc. An optional filtration system is configured to receive the first stream of water and perform a filtration operation thereon. A sterilization system is configured to perform a sterilization operation on the first stream of water. The water is then output from the sterilization system as potable water.

  • Patent number: 8647479
    Abstract: Provided is a standalone integrated water treatment system for a distributed water supply. A filter input receives water to be treated. A coagulation system is in operative connection with the filter input, wherein the water which has been filtered is subjected to a coagulation process performed by the coagulation system to create pin floc from suspensions in the water. A maturation buffer tank is in operative connection with the coagulation system, wherein floc is aggregated in size within the water. A spiral separator is in operative connection with the maturation buffer tank, and the water is separated into two water streams, a first stream of water having most of the floc removed, and a second stream of water which includes a concentrated amount of the floc. An optional filtration system is in operative connection with the spiral separator and is configured to receive the first stream of water and to perform a filtration operation on the first stream of water.

  • Publication number: 20130246313
    Abstract: A computer-controlled method of determining costs of power consumption in a data center includes monitoring power consumption for a customer, determine a cost of the power consumption for the customer, adjusting a cost of operation for the customer to include the cost of power consumption to produce an adjusted cost of operation for the customer, and comparing the adjusted cost of operation for the customer to a price for the customer.

  • Patent number: 8447993
    Abstract: A power control system in a data center has a plurality of physical servers, each server having a local controller, at least one virtual server coupled to at least some of the physical servers, and a central controller to control task loading on the physical servers through the virtual servers. A method of controlling power consumption in a data center includes receiving inputs from local controllers residing on loads, the inputs including data about power consumption on the loads, receiving as an input at least one quality of service requirement, and allocating tasks to at least one server based upon the quality of service and the power consumption on the loads.

  • Publication number: 20100314325
    Abstract: A system and method for treatment of water. An inlet is operative to receive source water having particles therein. A spiral mixer has a defined spiral channel operative to mix the source water with a coagulant material and an alkalinity material. The spiral mixer is formed to perform in-line coagulation and flocculation processes within the defined spiral channel to form aggregated floc particles. A buffer tank is operative to receive the aggregated floc particles from the spiral mixer. Spiral separator segregates contents of the buffer tank into affluent and waste water that has the aggregated floc particles therein. An outlet is operative to provide a first path for the affluent, and a second path for the waste water having the aggregated floc particles.
