Aquajet Systems EcoClear neutralizes hydrodemolition water and removes particles

Aquajet Systems AB, a global leader in hydrodemolition machine manufacturing, introduces the EcoClear water filtration system. The innovative machine works with Aquajet’s full line of hydrodemolition robots to treat the wastewater generated by the process by neutralizing water pH and greatly reducing its turbidity so that it can be safely released back into the environment.

The EcoClear system enables the hydrodemolition contractor to treat wastewater in real time and maintain an environmentally sound jobsite.

The EcoClear which is powered by Siltbuster Ltd., moves as much as about 88 gpm or about 5,283 gallons (20 cubic meters) per hour, through a series of treatment chambers that neutralizes alkaline water to a pH of 6 to 9 and reduces turbidity to just 20-25 mg particles/liter. The entire process can be watched monitored and controlled online with the RECO control system.

The machine works by pumping water expelled from an Aqua Cutter into an inlet chamber, where a flocculating agent is automatically added to help clump the particles in the water. The water then flows into a second chamber that introduces carbon dioxide to neutralize the pH. In the next chamber, the floc, or solid particles, settles into a storage hopper and is removed by the integrated pump. The water continues to another chamber for a second pH adjustment. A final monitoring tank confirms the water pH has returned to a neutral 7 before it’s pumped out.

The dynamic combination of the Aqua Cutter Hydrodemolition series and EcoClear work well in applications such as roads and bridges, ship cleaning, waste water plants and petrochemical plants.
