20130037492 | System and Method for Optimizing the Mixing of Hypochlorite with Ballast Water - Systems, apparatus and methods are provided for treating ballast water by chemical injection using an injector having a geometry that minimally obstructs the ballast water flow to accomplish homogeneous mixing of hypochlorite with the ballast water within a short distance. The injector is inexpensive and has a configuration that may be easily installed and maintained. | 02-14-2013 |
20120138516 | System for Treatment and Neutralization of Oxidizing Agents in Ballast Water - A system for treating ballast water includes one or more electrolytic cells in fluid communication with a salt water source and in fluid communication with one or more ballast water tanks, a means for controlling hypochlorite generation by the one or more electrolytic cells, and a neutralization system in fluid communication with the one or more ballast water tanks. The neutralization system includes a means for measuring presence of oxidizing agents in the ballast water, a reducing agent source in fluid communication with the ballast water, and a means for controlling the amount of reducing agent supplied to the ballast water in communication with the means for measuring presence of oxidizing agents in the ballast water. The system may include a flow meter for measuring a ballast water flow rate and/or a TOC analyzer for measuring a TOC content of the ballast water. | 06-07-2012 |
20110226704 | Wastewater Treatment Onboard Small Marine Vessels - Methods, apparatus and systems for treating wastewater onboard small marine vessels. A pre-determined volume of wastewater generated onboard the vessel is mixed with a larger volume of seawater. This mixture is disinfected and subjected to further oxidation. The excess oxidants are neutralized and the treated effluent is discharged overboard the vessel. | 09-22-2011 |
20100170854 | Sludge Dewatering and Drying - Methods, apparatus and systems for dewatering and drying the dewatered sludge. Sludge pumped into the sludge dewatering apparatus is mixed in-line with a pre-measured quantity of polymers to agglomerate solids entrained in the sludge. The agglomerated sludge is routed to a filtration station comprising filtration chambers. The filtration chambers are fitted with industry standard filter bag. The agglomerated sludge is subjected to dewatering in the filter bags and the dewatered sludge is subsequently compacted, dried and discarded. | 07-08-2010 |
