PRODUCT GROUP EXAMPLES:

• Wet Scrubber Effluent
• Disposal Site Leachate
• Salty Effluents
• Wastewater Concentrates

Within this industry we offer dryers which utilize waste heat for the complete drying of liquid wastes, primarily for wastewater treatment. Complete wastewater treatment facilities often include decanters, evaporators or sludge dryers. Other companies within mg technologies deliver equipment for these processes.

Spray dryer design and operating conditions are selected individually to meet the specific needs for the individual project. The drying medium may be flue gas from a solid waste incineration process, hot air from industrial processes, exhaust gases from gas motors or any other hot waste gas. The drying medium may also be created by combustion of any available fuel such as oil, natural gas or waste gas in the form of biogas for example.

We have supplied a number of spray dryers for the drying of wet scrubber effluent from municipal solids waste incineration plants. These plants normally utilise the hot flue gas exiting the economizer / air pre-heater. The spray dryer is thus located upstream from the acid gas scrubber. Alkaline reagent is often injected into the spray dryer together with the wet scrubber effluent to pre-scrub the flue gas.

We can offer spray drying technology for a wide range of pumpable liquid wastes. Aqueous solutions and wastewater, with a significant content of suspended material, may be dried in a spray dryer to produce a fine powder.
