Abstract: A method for filtering suspended solids from a feed fluid involves filtering the feed fluid by pumping the feed fluid through a first retentate channel of a first cross-flow membrane unit and through a second retentate channel of a second cross-flow membrane unit that is connected in parallel with the first membrane unit. The retentate exiting the units after filtering is pumped through a suspended solids concentrating path. While the filtering is being performed by both membrane units, at least one of the membrane units may be cleaned by performing a forward flush on it in which a portion of the retentate from at least one of the first and the second retentate channels is drawn into a forward flushing path. The forward flushing path is fluidly connected to the retentate channel of the membrane unit that is being forward flushed.

Abstract: Methods, systems, and techniques for desalinating a saltwater using a humidifier unit. The humidifier unit has a housing, which has a carrier gas inlet and a saltwater inlet. The humidifier unit also includes a packing, within the housing, having a surface with a critical surface tension of less than 25 mN/m according to the Zisman method. The packing is arranged to facilitate a saltwater that enters the housing through the saltwater inlet and a carrier gas that enters the housing through the carrier gas inlet to contact each other. The contact facilitates evaporation of the saltwater, which produces salt solids on at least a surface of the packing, a humidified gas and a concentrated brine.

Abstract: Systems, processes, and techniques for treating a saltwater contaminated with volatile compounds. The saltwater is evaporated, resulting in a gas composed of water vapor and gaseous volatile compounds. This gas is then condensed into a condensate contaminated with the volatile compounds. The contaminated condensate is biologically treated to remove those volatile compounds, producing a purified water. Latent heat released by the condensing is used to evaporate the purified water into the atmosphere in an energy efficient manner. The contaminated saltwater is accordingly evaporatively disposed of without creating an issue regarding how to manage substantial liquid water byproduct, and without emitting substantial amounts of the volatile compounds into the atmosphere.

Abstract: A process and system for removing ammonia from an aqueous ammonia solution. A first aqueous solution and the ammonia solution are flowed respectively through a first and a second separation chamber of a bipolar membrane electrodialysis (“BPMED”) stack. The first separation chamber is bounded on an anodic side by a cation exchange membrane and the second separation chamber is bounded on a cathodic side by the cation exchange membrane and on an anodic side by a bipolar membrane. The bipolar membrane has an anion-permeable layer and a cation-permeable layer respectively oriented to face the stack's anode and cathode. While the solutions are flowing through the stack a voltage is applied across the stack that causes the bipolar membrane to dissociate water into protons and hydroxide ions. The protons migrate into the second separation chamber and react there with ammonia to form ammonium ions that migrate to the first separation chamber.
