Wastewater Treatment – Grits Classifiers

Improperly treated wastewater will detrimentally impact humans and wildlife. Implementing superior wastewater treatment solutions is essential for preventing potentially toxic contamination of soil, water and even the atmosphere. Examples of harmful substances produced by poorly treated wastewater include excess amounts of decaying organic matter leading to oxygen depletion in lakes, proliferation of infectious pathogens and accumulation of poisonous metals in groundwater.

Removing both inorganic and organic debris from wastewater requires installation of grits classifiers for separating solids (grits) from wastewater. Grits classifiers further concentrate grits (sludge thickening) to facilitate disposal of wastewater treatment compounds.

How Do Grits Classifiers Work?

Made of carbon steel or stainless steel for long-lasting durability, Cinchseal’s rotary shaft seals can be used in municipal or industrial wastewater treatment plants, refineries and food, paper and chemical manufacturing facilities. Low installation and maintenance costs, combined with strong mechanical seals to prevent leakage, makes grits classifiers the top choice for all industries needing exceptional wastewater treatment.

Grit management and treatment is performed by wet or dry grits classifiers. Dry classifiers employ cyclonic separators to concentrate grit. Underflow is discharged from the separator for further removal of water following discharge from a slanted screw conveyor. This type of grits classifier is capable of handling medium amounts of organic grit discharge.

Wet grit classifiers receive a mixture of grit and water from a grit basin. Wet grit machines provide a large settling area in which grit settles and thickens rapidly. Wet classifiers can hold more organic grit discharge than dry grit classifiers.

Why is Sludge Thickening Important to Treating Wastewater?

The process of removing water from sludge produced by grits classifiers is called sludge thickening. Consolidation of debris by grits classifiers makes it easier to dispose of sludge properly by reducing its volume and weight. Sealing devices incorporated in Cinchseal products ensure leakage does not occur during this process.

Sludge is produced when solids flowing through grit chambers and/or screens are separated from wastewater in primary clarifiers (sedimentation tanks). A sedimentation tank allows several hours for gravity settling to occur so that sludge solids sink to the bottom of the tank. Scrapers move the “primary” sludge along the bottom of the clarifier. Sludge is then pumped out of a hopper for safe removal.
