The process can operate under both mesophilic and thermophilic temperature conditions and is designed to treat strong industrial wastewaters with high influent suspended solids and fat, oil, and grease concentration. The ADI-AnMBR process can be part of waste-to-energy or renewable energy streams which aim to produce biogas (methane) for energy use and result in high quality anaerobic effluent that could be discharged to a Publicly Owned Treatment Works (POTW) or further polished in an ADI-MBR.

Amiad Filtration Systems (Hall E, Stand 1945) is a global provider of filtration technology to industrial, municipal and irrigation users. Amiad will be exhibiting the Amiad Automatic Micro Fibre (AMF) self-cleaning filter which safeguards wastewater and domestic water. With no cartridges to replace, little or no chemical to handle, and minimal water and energy demand, the AMF delivers clean water with clean technology. AMF filters are comprised of dozens of cartridges created by tightly winding fine polyester fibres around a grooved plastic core to deliver degrees of filtration ranging from 20 to 10, 7, 3 or 2 microns. Particles are trapped between the fibres. When a target pressure differential is reached across the filter, the self-cleaning cycle is activated. A high-pressure stream of water is directed through the fibres. The stream is deflected by the grooves in the plastic core back through the fibres, dislodging the particles and flushing them out of the filter housing. The 20 micron AMF has been approved for turbidity removal before disinfection under the State of California's Title 22 regulations. The 2 micron AMF delivers 3 log (99.9%) removal of Cryptosporidium and Giardia.

The modules can be arranged in either two or four rows and each row can be operated as a separate filtration line.

JWC Environmental (Hall G, Stand 4329) designs, manufactures, supplies and services solids reduction, separation, removal and processing systems for municipal and industrial wastewater treatment. JWC is exhibiting the newly redesigned Screenings Washer Monster-XE (SWM-XE) which features a programmable controller, a new low profile tank design and a triple zone wash system for a clean discharge. Discharged screenings are cleaner, drier and less expensive to transport and dispose of at landfills. The SWM-XE is a self-contained, hopper-fed system used to grind, wash, compact and dewater the rags and rubbish captured by wastewater screens. It is available as part of JWC Environmental's (JWCE) complete Monster Separation System fine screen unit or for installation to accept solids behind current screens.

JWCE's Smart Controller logic has three fully programmable operational stages which continually monitor the operation of the system. Each stage provides separate controls to provide proper washing of solids. The new low profile wash tank design is large enough to deal with heavy solids loading and still properly wash material via separate inlet, washing and dewatering zones. Two inspection ports allow operators to visually inspect the inside of the tank. The low height profile also allows the SWM-XE to fit into challenging installation retro-fit requirements. The SWM-XE uses a triple zone spray wash system to eliminate nearly all faecal matter and reduce foul odours. An initial spray wash zone, in the hopper, washes incoming solids as they are fed directly onto the cutters of the grinder, allowing quick processing, especially when greasy material is involved. The second zone is located between the grinder and auger. This patented use of wash water, after the grinder, washes soft organics from ground captured solids and provides homogenous, dry discharge. The third wash zone is located in the lower tank and ensures the screen and pipe remains clear.

Toray (Hall H, Stand 5255) is a membrane manufacturer for water purification and wastewater reclamation, and offers expertise in membrane solutions such as MF/RO, UF/RO, and MBR technologies. Toray will be exhibiting the MEMBRAY submerged flat sheet MBR module. When used as a component of a MBR system, the MEMBRAY MBR module effectively removes suspended solids from activated sludge. This microfiltration module in a plate-and-frame configuration consists of flat sheet PVDF membranes which are cast with polyester, non-woven fabric as the base layer. This combination of materials gives the membrane superior physical strength and chemical stability. The Toray MEMBRAY MBR module is comprised of an element block and an aeration block. The element block contains the PVDF membrane filter elements stacked at equal intervals. Each element is connected via a polyurethane tube to a permeate water manifold. The aeration block consists of air diffusers used to supply air to the MBR module. The module can be submerged directly into an activated sludge tank for combining biological treatment and membrane separation. It eliminates the secondary sedimentation process and reduces the activated sludge tank size. The flat sheet MBR plate-and-frame configuration is inherently more resistant to fouling than the hollow fibre membrane configuration. Therefore, it results in fewer chemical cleaning requirements. The reduced module fouling from human hair and other obstructive substances allows for coarser screening as a pretreatment process.
