A process for treating oilfield waste water includes combining oilfield waste water and a biocide comprising hydrogen peroxide, the biocide being present in an amount effective to decrease a number density of bacteria in the oilfield waste water. The treated water can be reused in a subterranean environment.

Disclosed herein is a method of producing a polyaniline zirconia nanocomposite, and the uses of the thus produced polyaniline zirconia nanocomposite for the treatment of wastewater. The polyaniline zirconia nanocomposite is characterized in having a particle size of about 0.3 to 50 μm in diameter, an isoelectric point at about pH 6.2, and is capable of reducing at least 99% of the pathological microorganism and at least 60% of the phosphate in the wastewater after coming into contact with wastewater for 24 hrs and 12 hrs, respectively.

Various embodiments of the present technology provide methods and systems for soil enrichment. The systems may comprise a bioreactor system coupled to an initial treatment system for the cultivation of a live microorganism culture containing organic nutrients on an agriculturally effective scale. The systems may be automated and/or portable for practical applications onto target fields. The live microorganism culture may be delivered onto the soil of the target fields, enriching the soil with the organic nutrients that become bioavailable to crops growing in the soil. The soil enrichment system may provide a sustainable approach to agriculture that may efficiently enhance the natural processes of the native soil of any crop.

A reduction treatment agent made of a powder with a particle size within a range of 1500 to 3000 mesh, the powder containing: 20 to 40 parts of a mixed-oxide powder containing magnesium oxide and zinc oxide; and 60 to 80 parts of an organic acid powder containing calcium, ascorbic acid, citric acid and salt. The reduction treatment agent may further contain one to six kinds of metal powder selected from the group of copper, molybdenum, nickel, cobalt, iron and aluminum, each in an amount of one part. Due to this configuration, the reduction treatment agent can be easily mixed with various substances when added to those substances. Even if the target substance is not water, the agent can entirely and uniformly change that substance into a reduced state. Additionally, the reduction treatment agent can act as a surfactant, and therefore, can be used as cosmetics or food.

The present disclosure describes an augmented medium for water purification including a medium that is treated with Moringa oleifera coagulant protein (MOCP), as well as uses and methods of making the same. The present disclosure also describes water filters including such augmented medium, as well as methods of purifying water by using such filters.

A method of controlling cooling water treatment may involve measuring operating data of one or more downstream heat exchangers that receive cooling water from the cooling tower. For example, the inlet and outlet temperatures of both the hot and cold streams of a downstream heat exchanger may be measured. Data from the streams passing through the heat exchanger may be used to determine a heat transfer efficiency for the heat exchanger. The heat transfer efficiency can be trended over a period of time and changes in the trend detected to identify cooling waterfouling issues. Multiple potential causes of the perceived fouling issues can be evaluated to determine a predicted cause. A chemical additive selected to reduce, eliminate, or otherwise control the cooling water fouling can be controlled based on the predicted cause of the fouling.
