John Cockerill’s wastewater treatment for FGD Plants 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. 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.
Physical-chemical neutralization is a cost-effective way to clean even the biggest amounts of wastewater. John Cockerill neutralization plants include several processes like neutralization, flocculation, clarification and filtration according to the needs of the customer. Coagulation and flocculation convert wastewater components into solid sludge, which is dewatered using a chamber filter press. After neutralization wastewater is clean enough for discharge to sewage. Sludge is then taken care of as solid waste.
Flue gas desulphurization plants (FGDP) remove sulfur from flue gas. The effluent from coal, gas, or biomass fired power plants is effectively treated by our wastewater treatment plants utilizing the physical-chemical process (neutralization process). Typically lime (Ca(OH)2) or caustic soda (NaOH) is used as the neutralizing agent. These plants are designed for challenging environments with high levels of chlorine, temperatures, suspended solids, dissolved metals and abrasive substances.
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. John Cockerill has experience in energy industry documentation requirements.
Process automation is used to keep workers out of the dangerous chemicals and conserve the labour costs.
John Cockerill FGD Effluent wastewater treatment plants have an extremely high level of automation. The automated systems cover both process control and production control by constantly monitoring and adjusting chemical processes. As a result, payroll expenses can be reduced by up to 70 percent compared to manually operated plants. Automated plants are also much safer than manually operated plants.
