The Detritor Grit Removal system is a cross flow grit system that utilises a collector arm to move settled grit into a vessel for collection. It provides reliable removal of abrasive, heavy and insoluble inorganic grit, which can accumulate in municipal wastewater treatment plants.

With a wide selection of solutions, from freestanding grit classifiers to compact grit removal units, Ovivo’s grit removal systems provide best-in-class heavy solids removal to protect downstream processes from the adverse effects of grit. Ovivo is a powerful global brand with over 150 years of experiences and references in water treatment.

To effectively remove grit, detritors utilize a combination of gravity sedimentation and mechanical raking. The wastewater flow is slowed down in a dedicated tank, allowing heavier particles to settle to the bottom.

The grit settling unit or detritor is a continuous flow tank in which the grit settles due to gravity and the water overflows through the outlet weir on the opposite side. The settled grit is scrapped by means of a scraper mechanism towards the opening on the classifier sidewall at the bottom.

2016年12月14日 · This document provides design details for a mechanical detritor tank for grit removal from wastewater. The key details are: - The average flow is 60 MLD with a peak factor of 2.25, resulting in a peak flow of 135 MLD.

Detritors are a set of equipment that collectively remove fine grits from the influent stream. The equipment are typically part of the Pre-Treatment Unit (PTU), an integral part of most Sewage Treatment Plants (STP), irrespective of the secondary treatment process. The detritor is placed after a fine screen.

Generally used in sewage treatment plants/ effluent treatment plants, to remove the grit particles sizing greater than 0.15mm having density of 2.65. Load cell digital type / high tension spring loaded mechanical mercury bulb type. Shear pin arrangement for classifier.

Grit Separator/ Detritor. The detritor functions as a continuous flow tank where sedimentation occurs as a result of gravity, causing the grit to settle, while the excess water flows out through outlet weirs located on the opposite side.

Detritor tanks typically used flow directing vanes on the inlet and outlet which were angled to aid even flow distribution across the surface area of a square tank. Even flow distribution was critical to ensuring adequate settling time for the grit particles to drop to the bottom of the tank where they could be removed by rotating rake arms ...

The Detritor is a mechanism with three scrapers which circulates pushing grit into the grit collection chamber, where it awaits removal via a pump or Hydrake. The water and grit separate, drying the grit, the water then flows back into the machine.
