Abstract: A water treatment system that includes cationic polyacrylamide (cPAM) and xanthan (i.e., xanthan gum) effectively treats water contaminated with microorganisms such as harmful algal blooms (HAB). The combination of cPAM and xanthan forms cohesive thread-like flocs with the microorganisms entrapped therein. The flocs are then separated from the aqueous media, thereby removing the microorganisms. The combination of cPAM and xanthan has dramatically reduced toxicity compared to cPAM alone.

Abstract: A system and method for producing a recombinant Moringa oleifera coagulant protein (MO) in Bacillus includes the expression of a recombinant nucleic acid encoding the MO protein fused or linked to a Bacillus signal peptide (SP). The nucleic acid can also be modified by codon optimization for enhanced expression of the MO protein in bacteria. The recombinant MO protein has coagulation/flocculation activity and can be used in the treatment of contaminated water, particularly drinking water. Vectors and nucleic acid constructs encoding the MO protein and SP, and host bacterial cells are also disclosed.

Abstract: A recombinant Moringa oleifera coagulant protein (MO) produced and secreted by Bacillus has coagulation/flocculation activity. The MO protein and the Bacillus host cells expressing the MO protein can be used in compositions and methods for treating contaminated water, such as drinking water or waste water. The MO protein can coagulate or flocculate suspended solid impurities in the water, which can then be removed.

Abstract: The invention is a water recovery system that utilizes waste heat and a moving air stream to recover water with minimal use of energy and without the need to move water through filtration devices. The invention may be used for recovery and reuse of water for a wide range of emergency back-up, environmental, industrial, and mission-oriented purposes.
