Wastewater Grit Removal Systems

Wastewater treatment - Wikipedia

Wastewater treatment is a process used to remove contaminants from wastewater or sewage and convert it into an effluent that can be returned to the water cycle.Once returned to the water cycle, the effluent creates an acceptable impact on the environment or is reused for various purposes (called water reclamation). The treatment process takes place in a wastewater treatment plant (WWTP).There ...

City of Philadelphia: Wastewater Treatment

Next, wastewater flows through basins that allows heavy particles, called grit, to settle. Grit is composed of materials such as sand and gravel that enter the plant through storm sewers. Primary Treatment: Primary treatment physically removes many of the solids suspended in the wastewater as it flows slowly through primary sedimentation tanks.

Microalgae and wastewater treatment - ScienceDirect

Jul 01, 2012· In the wastewater treatment system (), the removal of biochemical oxygen demand (BOD), suspended solids, nutrients (NO 3--N, NO 2--N, NH 4 +-N and PO 4 3--P), coliform bacteria, and toxicity are the main goal for getting purified wastewater.BOD exploits the ability of microorganisms to oxidize organic material to CO 2 and water using molecular oxygen as an oxidizing agent.

Grit removal systems should also provide a means for washing the biomass from the grit. This is achieved in the high-rate mixing zones at the beginning of the process. The mixing zone''s energy requirements are decreased longitudinally through the grit tank for removal of various particle diameters.

Wastewater Odor Control: An Evaluation of Technologies | WWD

Dec 28, 2000· This byproduct has a low solubility in the wastewater and a strong, offensive, rotten-egg odor. In addition to its odor, H2S can cause severe corrosion problems as well. Due to its low solubility in the wastewater, it is released to the atmosphere in areas such as wet wells, headworks, grit chambers and primary clarifiers.

How Wastewater Treatment WorksThe Basics

burdens on wastewater treatment systems. Today''s pollutants, such as heavy metals, chemical com-pounds, and toxic substances, are more difficult to remove from water. Rising demands on the water supply only aggravate the problem. The increasing need to reuse water calls for better wastewater treatment. These challenges are being met through

Wastewater treatment - Primary treatment | Britannica

Wastewater treatment - Wastewater treatment - Primary treatment: Primary treatment removes material that will either float or readily settle out by gravity. It includes the physical processes of screening, comminution, grit removal, and sedimentation. Screens are made of long, closely spaced, narrow metal bars. They block floating debris such as wood, rags, and other bulky objects that could ...
