  • Transitional water treatment wall for dialysis
    Patent number: 11845676
    Abstract: A transitional water treatment wall for kidney dialysis is provided. The transitional wall includes several devices positioned on a mobile frame, the devices establishing fluid communication between a water source, pre-RO treatment equipment, and an RO system. The transitional water treatment wall also provides pressure and temperature control of the water being circulated. The mobile frame of the transitional water treatment wall includes wheels for providing ease of movement of the transitional water treatment wall. The mobile frame also limits space requirements for the various devices. The transitional wall also includes electrical outlets.
    Type: Grant
    Filed: July 8, 2022

  • Indirect drain flush system for dialysis effluent
    Patent number: 11497840
    Abstract: An indirect drain flush system incorporating hot water to facilitate the transport of kidney dialysis effluent to wastewater treatment facilities is provided. Heated water is discharged into a waste line through an air gap, and the heated water increases the molecular interchange of fatty substances in the dialysis effluent, decreasing the viscosity of those fatty substances and preventing them from coagulating or crystalizing on pipes and drains. An air admittance valve may prevent negative pressure from building up within the system.
