Abstract: Described herein are systems and methods for performing peritoneal dialysis. According to one aspect, the disclosure provides a sterile interface connection for connecting a water purification system to a disposable source of dialysate concentrates. The sterile interface connection can include a chamber comprising an inlet adapted to be connected to the water purification system on a proximal end and a valve on a distal end. The sterile interface connection can also include spring-loaded needle disposed in the chamber. The spring-loaded needle can move between a retracted configuration in which the spring-loaded needle is fully retracted into the chamber and the valve is closed and sealed, and an extended configuration in which the spring-loaded needle extends through the valve into the disposable source of dialysate concentrates.

Abstract: The present invention relates to methods for biological wastewater treatment for Se control in Se-laden wastewater. The Se contaminants in the wastewater include the Se oxyanions selenate (SeO42-) and selenite (HSeO3−), which are biochemically reduced and transformed to elemental selenium (Se0) by microorganisms through anaerobic biological reduction. The resulting Se0 is entrained in the biomass, which is further processed to enable the efficient recovery of concentrated Se0.

Abstract: Mobile water filtration enables on-site recycling of wastewater for reuse in mechanical decoking operations of fired-heaters, furnaces, boilers, or systems prone to build up of deposits, residue, or scale and enables on-site disposal of wastewater in a safe and environmentally conscious manner. In batch operations, a coagulant, a flocculant, and a plurality of cascaded filters of increasingly fine pitch may be used to treat wastewater and remove particulate matter, such as, for example, coke, for reuse or safe disposal. In continuous operations, a plurality of cascaded filters of increasingly fine pitch may be used. A control system may be used to automate the operation of a mobile water filtration system for use with a decoking system, such that it does not require human intervention exception for maintenance operations related to filters. The filtered water may be disposed of on-site, eliminating the need for further treatment or transport off site.

Abstract: A peritoneal dialysis system includes a cycler including a pump actuator, a heater and a heating pan operable with the heater, and a disposable set operable with the cycler. The heating pan includes a sidewall forming a slot. The disposable set includes a pumping cassette and a heater/mixing container. The pumping cassette includes a pump chamber configured to be actuated by the pump actuator. Additionally, the heater/mixing container is in fluid communication with the pumping cassette and is sized to be received at the heating pan. The heater/mixing container includes a port configured such that when the port is slid into the slot of the heater pan sidewall, the port is prevented from rotating about an axis transverse to a direction of flow through the port.
