Feed water is split into a first fluid stream, fed to a bypass conduit and a second fluid stream that is conveyed through a weak acid cation treatment bed. After passing through the bed, the treated fluid is combined with the bypass fluid stream to produce a blended feed water at the outlet. The ratio of the bypass fluid stream and treated fluid stream is a function of pH and L.S.I. A controller and associated sensors may control the relative flow rates between the bypass fluid stream and the treated stream to maintain a predetermined water parameter such pH, L.S.I., etc. within a predetermined range.

Method for managing the reversal frequency of an electrochemical reactor

Номер: US20130193080A1
Автор: Patrice Coquelle, Philippe Grard
Принадлежит: POOL TECHNOLOGIE

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.

A continuous flow granular/flocculent sludge wastewater process selects for granule biomass capable of nitrogen and phosphorus removal and controls granule size and concentration of granular and flocculent sludge for optimal nutrient, organic, and solids removal in a smaller footprint. A series of biological process zones lead to a secondary clarifier. Mixed liquor sludge, preferably from an aerobic zone, goes through a classifier or separator processing flow from the aerobic zone, to the secondary clarifier. In a sidestream process that can be included a portion of sludge preferably from an aerobic zone goes through a classifier or separator to selectively produce a granular-rich effluent, and the clarifier may also have a separator to further concentrate granular biomass, most of which is cycled back to an initial multi-stage anaerobic process zone. The anaerobic zone is structured and operated to encourage growth of granules in subsequent process zones. 1.

The working electrode prepared by the nano-catalytic material of the present invention has good denitrification performance in the environmental field, which can achieve nearly 100% nitrate removal rate, nearly 100% nitrogen selectivity and long-term stability. These properties are due to the prepared working electrode having an oxidizable copper (I, II/0, I), oxygen vacancy (O) and a one-dimensional nanowire structure. The structure can regulate the adsorption and reduction of intermediate products, resulting in nearly 100% nitrate removal rate and nearly 100% nitrogen selectivity. 1. A preparation method of a copper integrated electrode with a convertible oxidation state , comprising the following steps:1) cutting a copper foam into a copper foam strip, and washing the copper foam strip with ethanol and acetone to remove surface impurities of the copper foam strip to obtain a washed copper foam strip;2) drying the washed copper foam strip obtained in step 1) at room temperature to obtain a dried copper foam strip, and immersing the dried copper foam strip in a graphene oxide solution with a concentration of 0.1 mg/mL-10 mg/mL for 1 min-10 min, covering a surface of the dried copper foam strip with a carbon layer to obtain a carbon coated copper foam strip, transferring the carbon coated copper foam strip to a constant temperature oven, and drying the carbon coated copper foam strip for 1 h-10 h at 50° C.-100° C. to obtain a copper foam carrier;3) calcining the copper foam carrier obtained in step 2) for 1 h-5 h at ...

The application belongs to the technical field of water treatment, and relates to a biofilm electrochemical reactor for simultaneously removing nitrate nitrogen and trace organic matters in water. According to the principles of electrochemical reaction and products completely different under different cathode and anode material conditions, the reactor is divided into three functional regions, wherein first, an electrochemical reaction of producing hydrogen at a cathode and decomposing carbon at an anode is realized in a first functional region so as to provide a condition for reduction of nitrate nitrogen by a hydrogen autotrophic denitrifying bacteria of a particle electrode layer in a second functional region, after products generated by means of the electrochemical reaction and a biochemical reaction in the previous two functional regions enter a third functional region, pollutants such as trace organic components and residual ammonia nitrogen in water are oxidized and decomposed by using anodic oxidation function.
