Abstract: A heat management system for a building having at least one cooling device is provided. The heat management system includes a refrigeration system in heat exchange contact with a cooling system for providing cooling energy to the cooling system and to the cooling device. The cooling system includes at least two independent flow paths in heat exchange contact with the cooling device for cooling the cooling device. In addition, the heat management system includes a defrost system in heat exchange contact with the cooling device through the independent flow paths wherein the defrost system can be operated to independently defrost each flow path of the cooling system. The system is efficient to operate in conjunction with a geothermal system and provides effective building atmosphere de-humidification.

Abstract: An apparatus and method for the treatment of contaminated water by biodegradation is provided. In particular, the apparatus and method are suited for the biodegradation of volatile organic compounds (VOC's) such as trichloroethylene and related compounds or benzene and related compounds. The process employs an immobilized soil bioreactor (ISBR) having a headspace re-circulation system.

Abstract: A process and apparatus for the removal of aromatic amines from soil and water is described. In particular, treatment trains are described in which soil washing or low temperature desorption process effect removal of contaminant, such as xylidines from soil and steam stripping is utilized to remove contaminant from water. Further treatment through organic acid precipitation and advanced oxidation produce clean water and precipitated salts which may be recovered.
