  • Treatment and Disposal of Air Pollution Control Residue

    What is APCr? Thermal waste management using Energy Recovery Facilities (ERFs) is now a well-managed and mature technology that is subject to environmental monitoring by a range of competent international bodies. These ERFs have been established as a means of diverting waste away from landfill disposal and for valorising the material and energy content of the waste. Counter to historic ...

  • Used Furnaces & Ovens

    Industrial ovens and furnaces are both heated chambers used to process raw materials at higher temperatures than what can be obtained in open-air systems. There is a range of heat treatments possible with both industrial furnaces and ovens, and the main purpose of any heat treatment is to change the mechanical of physical properties of a material. Some examples of materials that benefit from heat ...

Montreal, Quebec, Canada The Problem: In 2001, a water quality audit revealed that two of the largest drinking water plants in the City of Montreal were out of compliance with Quebec’s latest water quality rules. In response to the audit, the city upgraded the 1,400 MLD Atwater and the ...

  • How to Choose the Best Wastewater Treatment System for Your Plant

    For industrial companies producing wastewater as a byproduct of their process, some type of wastewater treatment system is usually necessary. Failing to properly treat your wastewater can potentially harm the environment, human health, and your process, in addition to causing your facility to incur heavy fines and possible legal action if it is being improperly discharged into a publicly owned ...

  • Strategies for the reduction of Legionella in biological treatment systems

    A community-wide outbreak of Legionnaire's disease occurred in Warstein, Germany, in August 2013. The epidemic strain, Legionella pneumophila Serogruppe 1, was isolated from an industrial wastewater stream entering the municipal wastewater treatment plant (WWTP) in Wartein, the WWTP itself, the river Wäster and air/water samples from an industrial cooling system 3 km downstream of the WWTP. ...

  • Pd/RGO modified carbon felt cathode for electro-Fenton removing of EDTA-Ni

    Ethylenediaminetetraacetic acid (EDTA) forms stable complexes with toxic metals such as nickel due to its strong chelation. The electro-Fenton (EF) process using a cathode made from palladium (Pd), reduced graphene oxide (RGO) and carbon felt, fed with air, exhibited high activities and stability for the removal of 10 mg L−1 EDTA-Ni solution. Pd/RGO catalyst was prepared by one-pot synthesis; ...

  • Using respirometry for energy optimization in a nitrifying biological wastewater treatment system

    Many wastewater treatment plants use more than 50% of their total energy budget in the aeration basin and, when nutrient removal is included in the activated sludge process, it is very common that the majority of oxygen uptake goes to the nitrification process. For that reason, in most wastewater treatment plants, energy optimization is focused on nitrification management. This information can be ...
