  • Particulate Control Strategies for Incineration

    Abstract This paper discusses various particulate emission control strategies that can be employed for Municipal Solid Waste (MSW), Municipal Sewage Sludge, and Industrial Waste Incineration facilities. An example will be given of a particulate control installation that successfully cleans off-gases from an incinerator at a large photographic products plant. Data supporting a theoretical ...


  • New ion exchange processes for brine purification

    Three new ion exchange processes have recently been developed for purification of brine. The PDP (precipitator dust purification) process removes chloride contamination from byproduct sodium sulphate recovered from the electrostatic precipitator ofakraft pulp mill's recovery boiler. The BDS (brine de-sulphurization) process removes sulphate impurities from chlor-alkali cell brines, while a novel ...
