Abstract: Wastewater is treated though primary treatment of the water by way of a micro-sieve to produce a primary effluent and primary sludge. There is secondary treatment of the primary effluent by way of a membrane bioreactor (MBR) or an integrated fixed film activated sludge (IFAS) reactor to produce a secondary effluent and a waste activated sludge. The micro-sieve may have openings of 250 microns or less, for example about 150 microns. In a process, a gas transfer membrane is immersed in water. Pressurized air flows into the gas transfer membrane. An exhaust gas is withdrawn from the gas transfer membrane and used to produce bubbles from an aerator immersed in the water.

Abstract: A circuit assembly generally includes a circuit board and at least one electrical pathway configured to couple a thermoelectric module to the circuit board. The circuit board and the at least one electrical pathway form part of the thermoelectric module when the thermoelectric module is coupled to the circuit board via the at least one electrical pathway. The thermoelectric module, including the portion of the circuit board forming part of the thermoelectric module, defines a footprint that is smaller than a footprint of the circuit board. As such, the circuit board is capable of supporting electrical components on the circuit board in a position outside the footprint defined by the thermoelectric module.

Abstract: A membrane bioreactor (MBR) has membranes comprising a supporting structure. A supply unit doses a sorbent such as powdered activated carbon (PAC) into the MBR. The PAC is maintained at a concentration in the mixed liquor of 200 mg/L or more. Mixed liquor with the sorbent particles recirculates within the MBR at a flow rate of at least twice the feed flow rate. Air bubbles are provided to scour the membranes including during at least part of a permeation step. The sorbent particles are present in the mixed liquor and contact the membranes. Bioaugmentation products may be immobilized on PAC or other carriers and then added to an MBR or other bioreactors.
