  • Patent number: 6048452
    Abstract: A waste treatment device for treating waste having both liquids and solids therein includes a primary waste reservoir, a solids processor operably connected to the primary waste reservoir to receive waste therefrom in a manner to permit combustion of a substantial part the solids and generate a resultant waste, ash and gas, a secondary waste reservoir operably connected to the solids processor to receive the resultant waste, and a liquid processor operably connected to the secondary waste reservoir to receive the resultant waste in a manner to separate at least a part of the resultant waste into an environmentally safe water and resultant waste concentrate.

  • Patent number: 5928588
    Abstract: A process for the manufacture of porous structures comprises forming a dry mixture comprising a component providing primary separation capability, a component providing green strength reinforcement capability and, a component providing binding capability and selected from the group consisting of thermoplastic and thermosetting polymers; delivering the mixture to a suitable surface and building a desired thickness thereof; densifying the mixture into tile form desired for the porous structure; removing the densified porous structure from the surface; binding the component providing the primary separation capability by melting the mixture to a temperature of up to about 20.degree. C. higher than the melting point of any thermoplastic component providing binding capability.

  • Patent number: 5503735
    Abstract: A liquid purification system is disclosed. In this system water is pumped into a filter cartridge. A reverse osmosis filter membrane in the filter cartridge removes impurities from the water, but not all of the water passes through the membrane. Water passing through the membrane exits the filter cartridge through a first outlet port, and is sent to a storage tank. Water not passing through the filter membrane exits the filter cartridge through a second outlet port. This water then passes through a pressure relief valve. The pressure relief valve can be adjusted to vary the water pressure and flow rates in the system. Some of the water exiting the pressure relief valve passes through a flow restrictor valve and then to drain. The flow restrictor maintains a constant flow rate at variable pressures. In this system, the flow restrictor is operable to maintain the same flow rate through it to drain and through the first filter outlet port.
