A method is provided for supporting environmental control in a semiconductor wafer processing space, the method includes: flowing a first gas under pressure in a first direction through a first diffuser tube, thereby generating a first lateral flow of gas through a sidewall of the first diffuser tube; flowing a second gas under pressure in a second direction through a second diffuser tube, thereby generating a second lateral flow of gas through a sidewall of the second diffuser tube, the second direction being opposite the first direction; combining the first and second lateral flows of gas within a housing; and outputting the combined lateral flows of gas from the housing to produce a laminar gas flow covering an opening to the semiconductor wafer processing space.

A method and system of removing environmental contaminants from water comprising adding a fatty chemical to form a mixture with the water in which the fatty chemical and the environmental contaminants complex to form molecular complexes. The mixture is then filtered to remove the molecular complexes from the water.

Vessel configured to facilitate concentration of a product in a solution. The vessel may include outlet ports to deliver the solution to a processing system (such as a filtration system), and inlet ports. The inlet ports may be at progressively lower levels for return of fluid thereto reduced in volume as a result of filtration thereof. A smaller volume sump may be provided below a main tank of the vessel to facilitate concentration of the solution. The sump may include ridges facilitating collection of the product of interest from the solution, and/or reinforcing the sump walls, and optionally forming a vortex breaker. A spray ball may be provided to spray materials, such as buffer solution, into the vessel. The spray ball may direct materials to facilitate retrieval of product from the vessel. One or more components of the vessel may be advantageously formed of disposable material for single use thereof.

Processes and systems for filtering a liquid sample are provided. Batches of a liquid sample can be routed to two or more cycling tanks (e.g., first and second cycling tanks). Upon filling a first cycling tank, a first batch of the liquid sample can be routed to a filtration assembly by a continuous diafiltration process that includes routing produced retentate back to the first cycling tank or to a collection vessel. Upon filling a second cycling tank, a second batch of the liquid sample is routed to the filtration assembly by a continuous diafiltration process that includes routing produced retentate back to the second cycling tank or to the collection vessel. The filling and continuous diafiltration of batches of the liquid sample continues to alternate between the two or more cycling tanks until a total product volume is processed.
