The systems and methods allow specifically for the removal of contaminants from produced water from oil and gas wells, fracturing flow-back water, and water- or brine-based drilling fluids. The water is treated by contacting the contaminated fluid with ozone after contacting the fluid with a diffused air system to generate small bubbles for entrainment of some contaminants. Thereafter, the water is contacted with an electro-coagulation system in order to remove flocculants and adjust the pH and the total dissolved solids levels of the fluid.

The method for managing the polarity-reversal frequency of at least one pair of electrodes in an electrochemical reactor for water electrolysis includes observing a fluctuation in the hydrogen potential (pH) of the water, while carrying out a comparison of the pH measured at a given moment with a previous measurement or a predetermined initial value. An amount of treatment agent is injected into the water to adjust the pH to around a defined set point. The polarity-reversal frequency of electrodes is calculated on the basis of the temperature of the water, the pH fluctuation and amount of agent injected. The method includes estimating the total alkali strength on the basis of the injected amount and the pH fluctuation, anticipating the fluctuations in the pH relative to the preceding estimations, and readjusting complete alkalinity titration estimate and calculation of the polarity-reversal frequency.

Принадлежит: Individual

The present invention relates to the chemical engineering for getting useful products from aqueous solution of electrolytes with various concentration by electrolytic method and it can be used for the production of disinfectants widely utilized in medicine, biology, and ecology. This invention solves a task of disinfectant production with the capacity of a single electrolyser amounting to 1200 litres per hour and up to 600 grams of active chlorine per hour by utilizing 3-7 gram sodium chloride (NaCl) for the production of 1 gram of active chlorine on the basis of a reliable and safe hydraulic structure. The main condition for the effective solving of the task is the initial directing of fresh water supply into the internal tubular cathode chamber for the cathode cooling purposes, before the participation in final disinfectant production process. A coolable cathode enables to increase the hold-up time of the electrolyte in the electrode chamber without application of circulation circuits improving significantly the efficiency of sodium chloride utilization. The simplicity of the method makes it possible to increase both the productivity of a single electrolyser and the efficiency of the process.
