    摘要: A process for removing pollutants or minerals from lake, river or ocean sediments or from mine tailings is disclosed. Magnetically attractable collection units containing an ion exchange or sorbent media with an affinity for a chosen target substance are distributed in the sediments or tailings. After a period of time has passed sufficient for the particles to bind up the target substances, a magnet drawn through the sediments or across the tailings retrieves the units along with the target substance.

    摘要: A method for forming agglomerated ion exchange particles in which finely divided synthetic resin coating particles are affixed to the surface of synthetic resin substrate particles. The surface of the coating particles have ion exchange sites with monovalent counterions (e.g., negatively charged) which are attracted to the ion exchange sites on the substrate particles. Multivalent ions (e.g., carbonate) of the same charge as such monovalent counterions are mixed into an aqueous disperson of the coating particles to displace the monovalent counterions thereby increasing the electrostatic charge density of the coating particles. Then, a slurry of the synthetic resin substrate particles is added dropwise to this dispersion which is mixed to form agglomerates by electrostatic attraction.

    摘要: An anion exchange resin, containing Al(OH).sub.3 suspended therein, is reacted with aq. LiOH to form microcrystalline LiOH.2Al(OH).sub.3 which is then reacted with a halogen acid or halide salt to form microcrystalline LiX.2Al(OH).sub.3. The resin, after having a portion of the LiX eluted by using an aqueous wash, is used to recover Li.sup.+ values from aqueous brines.

    摘要: For on-site, continuous, bulk water purification, a dual-monitored, two-pass system employs two successive banks of mixed-bed, strong-based resin cylinders. Raw water first flows down through a bank of primary cylinders in parallel. The outlets of the primary cylinders are connected in parallel via an overhead carry-over pipe to a smaller bank of polisher cylinders whose outlets are connected in parallel via a final filter to a discharge outlet. Probes monitoring the concentration of impurities are located in the carry-over pipe and following the final filter. The efficient arrangement of cylinders in a van allows easy replacement of exhausted cylinders without interrupting water treatment.

    摘要: A portable domestic water purification and filtration apparatus includes a container for treating water to having a reservoir for storing untreated water and a pump having an inlet connected to pump water from the bottom of the reservoir and an outlet connected within the container to the inlet of a filter device also located within the container. The filter device includes an integral outlet spout for discharging the filtered water over the upper edge of the container.
