A monitoring assembly includes a diverter, a fluid delivery network, an analysis subsystem, and a pump. The diverter be configured to fluidly couple to a single port of a process pipe. The network can be configured to receive a process fluid including an incumbent additive from the diverter. The analysis subsystem can be configured to receive the process fluid from the network, to measure a predetermined property of the received process fluid within a sensing chamber, and to output a signal representing the measured property. The pump can be configured to urge the process fluid from the analysis subsystem to the diverter via the network. The assembly can also include a conditioning subsystem configured to treat the process fluid with a process additive prior to measurement. The assembly can further include a filtration subsystem configured to filter the process fluid prior to measurement.

The present disclosure relates to biocide compositions, formulations and methods for using formulations. In particular the present disclosure relates to biocide compositions and their use in treating reverse osmosis membranes.

In some embodiments, a method may include treating pulp in pulp and paper mills. The methods may include providing a peracetate oxidant solution and generating a reactive oxygen species. The peracetate solution may include peracetate anions and a peracid. In some embodiments, the peracetate solution may include a pH from about pH 10 to about pH 12. In some embodiments, the peracetate solution has a molar ratio of peracetate anions to peracid ranging from about 60:1 to about 6000:1. In some embodiments, the peracetate solution has a molar ratio of peracetate to hydrogen peroxide of greater than about 16:1. The peracetate oxidant solution may provide enhanced treatment methods of bleaching, brightening, and delignifying pulp fibers involving the use of peracetate oxidant solutions.

The present invention concerns a method for treating the production water originating from enhanced hydrocarbon recovery, and containing one or more water-soluble polymers and Fe.sup.2+ ions, consisting of at least partially oxidizing the Fe.sup.2+ ions by introducing at least one reaction activator and oxygen into said production water, the molar ratio of introduced oxygen to Fe.sup.2+ ions being less than or equal to 0.25.

A method of scavenging acid sulfide species from an industrial or environmental material, the method comprising contacting the material with: (a) propenal and/or maleimide and/or ethyl-2-chloroacetoacetate; and (b) a base.

Methods are provided to inhibit corrosion in low hardness water systems. The corrosion inhibiting treatment comprises: calcium salts of low molecular weight polymer polycarboxylic acids. These calcium salts may be added preformed to the water system in need of treatment or formed in-situ in the system. This method of corrosion inhibition is not a source of addition phosphorous or heavy metal to the treated system.

A water delivery system for delivering demineralized water to a consuming unit of a motor vehicle, in particular to a combustion engine, encompassing: a water tank having a filling opening; a first aspiration line; a first water pump; a discharge line; a discharge apparatus; a demineralization apparatus for demineralizing water; the first water pump being fluidically connected via the first aspiration line to an internal volume of the water tank; the discharge apparatus being fluidically connected via the discharge line to the first water pump.

The vehicular water-dispensing method incorporates a water recovery process, a water STT process, and a discharge process. The water recovery process: a) converts water contained in a gas phase in the atmosphere into water in a liquid phase; b) initially treats the converted liquid phase water to remove microorganisms and other chemical contaminations; and c) transports the initially treated liquid phase water to the water STT process. The water STT process: a) receives and stores the initially treated (liquid phase) water from the water recovery process; b) subsequently treats the stored water with a final treatment to remove microorganisms and other chemical contaminations; and, c) transports the treated stored water to the discharge process. The discharge process: a) receives the water from the water STT process after the final treatment; and, b) controls the discharge of the water received from the water

A solar distillation system for producing a distillate and providing cooling for a structure or appliance, and a method of using the system to produce a distillate and cool a structure or appliance. The system includes a distillate cooling coil, a secondary cooling coil, an expansion valve which is capable of controlling an amount of a coolant that flows through each of the coils. The system also includes a compressor, a plurality of sensors including a temperature sensor and a distillate flow sensor, and a controller which receives input from the sensors and controls the activity of the compressor and expansion valve. The system is capable of producing distillate at night in the absence of solar radiation.
