FGD Wastewater Treatment Plants

Wastewater Treatment Plants for Flue Gas Desulphurization (FGD) and other Power Plant Applications

Galvatek’s wastewater treatment plant solutions for power plant applications are typically part of the flue gas cleaning systems of coal-fired power plants, but also in biomass power plants.

Energy efficiency and environmental friendliness

Heavy metal removal application in flue gas cleaning plants

The main purpose of these plants is to remove heavy metals and suspended solids from the effluent of a flue gas cleaning plant, which further prevents damage to the environment by substances entering the sewage system. Each plant is tailor-made and designed according to the customer’s specific requirements.

Sulphur neutralisation process in challenging environments

Flue gas desulphurisation plants (FGDP) remove sulphur from flue gas. The effluent from these plants is effectively treated by our wastewater treatment plants utilising the physical-chemical process (neutralization process). Typically lime (Ca(OH)2) or caustic soda (NaOH) is used as the neutralising agent. These plants are designed for challenging environments with high levels of chlorine, temperatures, suspended solids, dissolved metals and abrasive substances.

Up to 50 m3/h capacity

The wastewater treatment plants of flue gas cleaning plants are always scaled and designed according to the needs of the customer and the quantity of the wastewater to be treated. Typically these plants can process up to 50 m3/h, but Galvatek can also deliver larger plants as required.

Featured technical innovations

Automation - Galcont™

Galvatek's Galcont™ process automation system has been constantly developed and improved for already four decades to meet ever-increasing demands in surface treatment plant control.

Ventilation System - Candovent™

Galvatek’s Candovent™ ventilation system allows placing the surface treatment line anywhere in the production layout, without the need to build an encapsulated room around it.

Energy Efficiency and Environmental Friendliness

Every aspect of Galvatek plants has been optimized with energy efficiency and environmental friendliness in mind.

Process Tanks

Process tanks have to be able to withstand many different types of chemicals like strong acids or alkaline. Durability and sustainability are emphasized in Galvatek's tanks.
