A municipal wastewater storage lagoon was filled with sludge that needed to be removed and disposed of. IAI used a PTO-driven 6” Houle pump to remove the sludge from the lagoon and transfer it to a mix tank. The sludge slurry was pumped from the mix tank, dosed with polymer and transferred to a trailer-mounted belt filter press for dewatering. The dewatered … [Read more...]
Mechanical Dewatering
IAI has successfully utilized mechanical dewatering processes, such as belt presses and dredged material classifiers, to dewater hydraulically dredged sludge and coal ash (CCR) from municipal and industrial facilities. These are some of our mechanical dewatering projects.
Industrial Wastewater Lagoon Dredging
IAI was contracted to remove and dewater 13,500 cubic yards of accumulated sludge from three wastewater treatment lagoons at a manufacturing facility in Quincy, Michigan. The sludge was hydraulically dredged using an 8 inch diameter auger head dredge and dewatered using mobile (trailer-mounted) belt filter presses. After dewatering, the sludge was loaded … [Read more...]
Coal Ash Maintenance Dredging
IAI was responsible for dredging approximately 20,000 cubic yards of coal ash (or fly ash) from a pond at a power plant in Tonawanda, New York. Hydraulic dredging of the 7.3 acre pond was completed over a 5 week period. The dredged material was dewatered using a Total Clean System. Effluent from the Total Clean unit was injected with polymer, then allowed to … [Read more...]
