A liquid desiccant system for controlling a temperature inside an enclosure includes an evaporative cooler system configured to cool an air stream AA entering the enclosure during day time; a liquid desiccant night cooler (LDNC) system configured to cool down and dry an inside air stream AE of the enclosure by using a liquid desiccant during the night; and a controller configured to switch on the LDNC system during the night.

Liquid dessicant cooler system and method

A liquid desiccant system for controlling a temperature inside an enclosure includes a liquid desiccant evaporative cooler (LDEC) system configured to cool down an incoming air stream (AA) entering the enclosure by using a first liquid desiccant; a liquid desiccant humidity pump (LDHR) system configured to remove humidity from a humid air stream (AD) that exists the enclosure by using a second liquid desiccant; and a storage system fluidly connected to the LDEC system and to the LDHR system and configured to separately store the first liquid desiccant and the second liquid desiccant. The humid air stream (AD) includes water vapors from the first liquid desiccant and from inside the enclosure.

Liquid desiccant based humidity pump, evaporative cooler, and air purification systems

Provided herein is a universally applicable biofouling mitigation technology using acoustically excited encapsulated microbubbles that disrupt biofilm or biofilm formation. For example, a method of reducing biofilm formation or removing biofilm in a membrane filtration system is provided in which a feed solution comprising encapsulated microbubbles is provided to the membrane under conditions that allow the encapsulated microbubbles to embed in a biofilm. Sonication of the embedded, encapsulated microbubbles disrupts the biofilm. Thus, provided herein is a membrane filtration system for performing the methods and encapsulated microbubbles specifically selected for binding to extracellular polymeric substances (EFS) in a biofilm.

Acoustically excited encapsulated microbubbles and mitigation of biofouling

A membrane system including an anti-fouling layer and a method of applying an anti-fouling layer to a membrane surface are provided. In an embodiment, the surface is a microfiltration (MF) or an ultrafiltration (UF) membrane surface. The anti-fouling layer can include a stimuli responsive layer and a dynamic protective layer applied over the stimuli responsive layer that can be a coating on a surface of the membrane. The stimuli responsive polymer layer can act as an adhesive prior to coating with the dynamic protective layer to aid in adhering the dynamic protective layer to the membrane surface. The dynamic protective layer can be formed by suitable nanoparticles that can prevent adhesion of foulants directly to the membrane surface. The stimuli responsive layer can be responsive to physio-chemical stimuli to cause a release of the stimuli responsive layer and the dynamic protective layer including foulants from the membrane.
