Abstract: The present disclosure provides an electrodialysis stack that may be used for the treatment of an electrically conductive solution. The stack includes two electrodes (at least one is a recessed electrode), a plurality of ion-transport membranes and stack spacers. The membranes and spacers are arranged between the electrodes to define electrodialysis cell pairs. The stack includes an electrically insulated zone that extends substantially from a distribution manifold past the recessed edge of the electrode and substantially from the recessed electrode to the opposite electrode for a distance that is about 8% to 100% of the total distance between the electrodes. The overlap distance that the electrically insulated zone extends past the recessed edge of the electrode is calculated as:


distance in cm=(0.062 cm−1)*(exp(−60/total cp)*(area in cm2 of the manifold ducts of the concentrated stream at the recessed edge)+/−10%.

Abstract: A method for monitoring and controlling unwanted polymer byproduct generated in a monomer production, storage, or handling process, for example polystyrene in a styrene production process, is described. The method comprises receiving a sample (115) taken during a monomer production process by a Fourier-Transform infrared spectrometer (120), performing an infrared spectroscopy analysis on the sample to generate spectral data (122) by the Fourier-Transform infrared spectrometer, and determining a percentage (119) of at least one polymer in the sample by mathematical correlative processing of the spectral data by a computing device (110).

Abstract: A spiral wound membrane module is suitable for use with high temperature water that may also have a high pH, for example steam injection produced water. The module uses a membrane with a polyphenylene sulfide (PPS) backing material. The feed spacer of the module may be made from polyphenylene sulfide (PPS) or ethylene chlorotrifluoroethylene (ECTFE). The permeate carrier may be made of a woven nylon (i.e. nylon 6, 6) fabric coated with high temperature epoxy. The core tube and anti-telescoping device may be made of polysulfone. In some examples, the module may be used at a temperature of up to 130° C. Optionally, the module may be used at a pH of 9.5 or more. In a filtration method, the module may be operated at a pressure in the range of 150 to 450 psi. The module may be operated at a generally constant pressure.

Abstract: A hybrid membrane aerated biofilm reactor (MABR) and activated sludge (AS) system and process are described herein. At least a portion of the AS system includes aerobic mixed liquor, for example in an aerobic tank or zone downstream of a tank or zone containing membrane aerated biofilm modules. The flow of air to the membrane aerated biofilm is modulated considering the ammonia loading rate to the system or to the aerobic mixed liquor, for example according to a diurnal cycle. For example, air flow to the membrane supported biofilm can be below an average or initial air flow rate during a period of low ammonia loading. Air flow to the aerobic mixed liquor may remain essentially constants during the same period. Optionally, mixed liquor around the membrane aerated biofilm modules may be aerated during a period of high ammonia loading.

Abstract: A conventional media filter such as a gravity sand filter is converted into a membrane filter. The media is removed and replaced by immersed membrane modules. Transmembrane pressure is created by a static head pressure differential, without a suction pump, thereby creating a membrane gravity filter (MGF). Preferred operating parameters include transmembrane pressure of 5-20 kPa, 1-3 backwashes per day, and a flux of 10-20 L/m2/h. The membranes are dosed with chlorine or another oxidant, preferably at 700 minutes*mg/L as Cl2 equivalent per week or less. The small oxidant does is believed to provide a porous biofilm or fouling layer without substantially removing the layer. The media filter may be modified so that backwash wastewater is removed from near the bottom of the tank rather than through backwash troughs above the membrane modules. Membrane integrity testing may be done while the tank is emptied after a backwash.
