TLDR
In this article, a method for treatment and disposal of propellant wastewaters, soil washwaters or groundwaters having dissolved perchlorate salts is described, which comprises adding to the contaminated water in an anaerobic reactor a mixed bacterial culture containing a specific bacterium, HAP1, which uses perchlorates as its terminal electron acceptor and thus reduces the per chlorate ion to chloride in the water.Abstract:
A method for treatment and disposal of propellant wastewaters, soil washwaters or groundwaters having dissolved perchlorate salts is described, which comprises adding to the contaminated water in an anaerobic reactor a mixed bacterial culture containing a specific bacterium, HAP1, which uses perchlorate as its terminal electron acceptor and thus reduces the perchlorate ion to chloride in the water; maintaining the proper nutrient and environmental conditions for HAP1 to optimally reduce perchlorate in the water and discharging effluent wastewater from the anaerobic reactor to an aerobic reactor and maintaining proper nutrient and environmental conditions for the optimal conversion of soluble organics to carbon dioxide and sludge and reduction of BOD, COD, ammonia and odor in the effluent water.read more

Identification of an anaerobic bacterium which reduces perchlorate and chlorate as Wolinella succinogenes
TL;DR: The morphological, physiological and 16S rRNA sequence data indicated that bacterium HAP-1 is a strain of W. succinogenes that can utilize perchlorate or chlorate as a terminal electron acceptor.
Journal ArticleDOI
Perchlorate biodegradation for water treatment.
TL;DR: Biological reactors currently treat nearly 30 million liters of perchlorate-contamined groundwater per day, and in situ treatment techniques are now showing success at the field scale.

Perchlorate reduction by a mixed culture in an up-flow anaerobic fixed bed reactor
TL;DR: This is the first report of an anaerobic mixed culture forming a biofilm capable of perchlorate reduction, and scanning electron micrographs demonstrated that the external and internal surfaces of the diatomaceous pellets were densely colonized with microbial cells of multiple cell types.
Patent
Automated closed recirculating aquaculture filtration system
TL;DR: In this article, an automated aquaculture system consisting of one or more culture tanks (10) connected to a closed system of filters (22) and ultraviolet (80) or ozone sources for water purification prior to returning water to the culture tanks was presented.
Patent
Treatment of spent caustic refinery effluents
TL;DR: In this article, a spent caustic refinery effluent is supplied to a submerged combustion gas evaporator in which hot combustion gas containing carbon dioxide is injected into the caustics liquid to concentrate the liquid and convert a hydroxide constituent to a carbonate.

Process for purification of industrial waste waters from perchlorates and chlorates
Vladimir Nikolaevich Korenkov,Vitaly Ivanovich Romanenko,Sergei Ivanovich Kuznetsov,Jury Viktorovich Voronov +3 more
TL;DR: In this article, a strain of the microorganism Vibrio dechloraticans Cuznesove B-1168 was grown by successive inoculations on a liquid nutrient medium containing sources of carbon, nitrogen, and phosphorus under anaerobic conditions in the presence of a perchlorate as a donor of oxygen.
Patent
Microbial degradation of DDT
TL;DR: A process for the microbial degradation of DDT which comprises treating the DDT with certain nonpathogenic, hydrocarbon-utilizing strains of Nocardia, Candida and penicillium until the DDTs has been substantially degraded is described in this article.

Conversion of hazardous materials using supercritical water oxidation
TL;DR: In this paper, a process for the destruction of hazardous materials in a medium of supercritical water without the addition of an oxidant material is described, where the harzardous material is converted to simple compounds which are relatively benign or easily treatable to yield materials which can be discharged into the environment.
