PENETRON Defeats Contaminants at Conemaugh
The Conemaugh Power Plant in Western Pennsylvania (USA) just completed an environmental upgrade that now ensures the containment tank is completely waterproof and resistant to any chemicals in the pollutants. PENETRON technology provided the optimal solution for the new structures by treating the concrete with PENETRON ADMIX.
The Conemaugh Power Station is a 1,711 MW (coal-burning) power plant located across the Conemaugh River from New Florence, in Western Pennsylvania (USA). The power station generates electricity with two steam turbines running on steam produced by twin 850 MWe boilers. The two hyperbolic cooling towers provide recirculating water to cool and condense the steam and limit the amount of water drawn from the river.
The plant uses more than four million tons of coal each year, and the facility’s newly completed environmental upgrades give the power plant the necessary capacity to contain ash and ash sediments. The new containment tank prevents runoff and drainage generated by the facility from contaminating the Conemaugh River or polluting the adjacent wetland areas located between the plant and the river.
Between 3,500-4,000 cubic yards of concrete (used for the containment tank) were treated with PENETRON ADMIX to ensure a waterproof structure and also provide resistance to any chemicals contained in the ash. The admixture was added in soluble bags that dissolve immediately when mixed into the concrete, simplifying the dosage and mixing process.
“PENETRON was brought on to the project by Fi-Hoff Concrete Products, a supplier of ready-mix, precast, masonry and construction products after they heard how successful PENETRON ADMIX was on the Consol Water Treatment Plant in West Virginia,” adds Christopher Chen, Director of The PENETRON Group.
In addition to the environmental and concrete durability benefits, PENETRON ADMIX was used in many concrete pours utilizing cold weather placement precautions. The coordination and preparation with the ready mix supplier and the contractor helped keep the project on schedule even during sub-freezing weather conditions.
