The experimental data was obtained using a pilot plant constructed in Chobeineh wastewater treatment plant in Ahvaz city, fed by activated sludge effluent in 3 levels of electrical conductivity (EC) (10, 15, 20 ms cm−1), during 45 days of the experiment.
The significant increase in settling velocities indicated that the ANAMMOX granules had a highly dense and compact structure which is more effective for sludge-effluent separation in the treatment system.
The main entries for pharmaceuticals such as DCF or FA in ground and surface water are sludge or effluents of wastewater treatment plants (WWTP) where the pollutants are insufficiently degraded.
Because of its peculiarities, AD can be a key technology in the field of the so-called 'green economy' for the management of the organic wastes (biowaste, sludge, livestock effluents, agro-waste, etc). in order to recover energy and organic matter.
Many industries dump sludge and effluents laden with heavy metals and persistent organic compounds in open areas, in rivers, and around residential areas, in gross violation of national laws.
The uncertainty and variability of potential nanomaterial inputs, nanomaterial properties, and the operation of the wastewater treatment plant contribute to the difficulty of predicting sludge and effluent nanomaterial concentration.
Moored off the quay of the Arsenale, the barge is partly filled with the city's sludge (the effluent has been treated and doesn't stink).
The disposal of industrial sludge from effluent treatment plant is a global concern to the industries not a unique problem for the pulp and paper industry.
Among different sources of nitrogen components, anaerobic sludge digesters effluent (sludge rejected water) generally contains 15 25 % of the total nitrogen load in a flow and is recycled to the head of the sewage treatment works (Mata-Alvarez 2002; Dosta et al. 2007).
The MBR process holds a promising future for a multitude of reasons, namely smaller footprints, less sludge, an effluent suitable for reuse in irrigation, and a high loading rate capacity.
