A system and method for removing ammonia from an ammonia-containing liquid is described. The system comprises a primary heat exchanger 12 for heating the ammonia-containing liquid to operational temperature, an ammonia stripper 14 for stripping ammonia from the ammonia-containing liquid from the primary heat exchanger and discharging it as ammonia-containing gas, and an acid scrubber 16 for reacting the ammonia in the ammonia-containing gas with acid to form an ammonium salt. The acid scrubber comprises a scrubbed air outlet 32 in fluid communication with a hot air inlet 20 of the ammonia stripper, such that scrubbed air which is discharged from the acid scrubber may be recycled for use in the ammonia stripper. Also described is a system and method for removing ammonia from an ammonia-containing liquid, wherein the system comprises a cold-water scrubber for removing ammonia from the ammonia-containing gas discharged from the ammonia stripper.

A waste peptone disposal system is provided, the system utilizing steam to increase the temperature of the waste peptone and provide active homogenous mixing inside a thermally insulated tank. Steam is introduced through a steam sparging system and directly applied to the waste peptone to reduce noxiousness, allowing the facility to dispose of the processed waste peptone through a wastewater system.

A water heating and treatment system includes a water heater operatively coupled to a water heater controller, a hot water outflow line from the water heater, and a cold water supply line to supply water to the water heater. The cold water supply line includes at least one of an anti-scale device operatively coupled to an anti-scale device controller, and at least one sanitation device operatively coupled to a sanitation device controller. The mixing station is operatively coupled to a mixing station controller. The mixing station supplies heated water to at least a first temperature zone at a first hot water temperature. Controllers of the water heater controller, the anti-scale device controller, the sanitation device controller and the mixing station controller are co-located at a front of a single enclosure behind an openable door, the controllers operatively coupled to a supervisory controller.

A gasification system according to an aspect includes a scrubber device to transfer contaminant contained in a flammable gas to cleaning water and discharge the cleaning water containing the contaminant as scrubber wastewater, a heat exchange device to heat the scrubber wastewater to vaporize the contaminant contained in the scrubber wastewater; and a combustion furnace to incinerate the vaporized contaminant, wherein the heat exchange device heats the scrubber wastewater by using heat generated by the combustion furnace.

A system for separating solids from a fluid mixture includes a vessel including a first chamber to receive a solid-laden fluid mixture, and a second chamber to receive liquids separated from the solid-laden fluid mixture. In certain aspects, at least one eductor is disposed in the first chamber to flow the solid-laden fluid mixture out of the first chamber. In certain aspects, an auger is disposed in the first chamber to move at least solids of the solid-laden fluid mixture out of the first chamber.

The present invention provides stretchable laminates with a flat appearance on the visible surface. The laminates comprise a textile layer, a functional layer, and a plurality of elastic fibers. The plurality of elastic fibers are in a substantially parallel arrangement and the internal distance between adjacent fibers does not exceed the maximum fiber spacing, which depends on laminate thickness in a stretched state. Also provided are garments and footwear comprising the stretchable laminates and methods of producing the stretchable laminates.
