Grit Classifier for Solids / Water Separation
General Description
Founded in 2009, EPS Wastewater provides industrial customers with reliable, efficient, and cost-effective wastewater treatment solutions. A team of engineers, scientists, technicians, and customer service specialists works together to solve complex industrial wastewater challenges.
EPS Wastewater sought to improve the efficiency of its BOF scrubber water treatment process by reducing the amount of water disposed of with collected solids. Under current methods, the material was loaded into 30-cubic-yard dumpsters and hauled to a landfill, leading to excessive water disposal and higher hauling and disposal expenses.
To address this challenge, KWS provided a grit classifier designed to separate solids from the water stream. The grit classifier produces drier solids for landfill disposal while allowing cleaner effluent water to be discharged to the municipal sewer system.

KWS Advantages
KWS worked closely with EPS Wastewater throughout the design process to develop a grit classifier that integrated seamlessly within the existing facility footprint. Drawing on decades of experience in the design and manufacture of grit classification equipment, KWS delivered a dependable solution that enhances solids dewatering, reduces disposal costs, and improves operational efficiency. The collaborative approach between KWS and EPS Wastewater helped ensure a smooth installation.
KWS Special Features
Since grit is extremely abrasive, KWS lined the interior of the classifier trough with ceramic tiles. Engineered for the toughest environments, ceramic tile liners deliver exceptional abrasion resistance and long-lasting protection of the conveyor trough. Ceramic tile liners lower maintenance costs, and minimize downtime, resulting in improved reliability and extended equipment life
The shaftless spiral is manufactured from proprietary KWS Micro Alloy 235 material, selected for its exceptional durability and wear resistance in demanding conveying applications. The KWS Micro Alloy 235 construction enables the grit classifier to reliably process abrasive and difficult materials while reducing maintenance demands and maximizing equipment uptime.
The KWS grit classifier is equipped with a proprietary one-piece flanged drive shaft engineered for superior strength and reliability. Precision-machined from solid bar stock, this robust drive shaft is backed by a lifetime warranty, providing long-term performance and peace of mind.
