Introduction
Grit and other solid materials, such as sugar sands and silt, are a costly component of both process water and wastewater in WWTPs, clogging systems, reducing efficiency, and causing abrasion damage and wear, necessitating more cleaning, maintenance, and repair.
Aggregates like gravel and sand, must be washed, to recover microscopic particles and remove siltthat attaches to their surfaces. Sand washing water may usually be recycled by using settling ponds, where larger particles drop to the bottom and are recovered to be replenished.
How do you remove silt and solids from water?
The aggregate production business incurs enormous costs in the recovery and storage of these materials, which must be thrown with excavators, trucks, and employees at a later stage, partly due to the need to allocate a vast space to these operations.
Fortunately, technology for capturing coarse, fine, and ultrafine materials from industrial water are available. Screens and hydrodynamic separators remove large amounts of solids with little power and a tiny footprint.
The Netsol filter press eliminates settling ponds and generates dry cakes that are simple to store and dispose of. It also recovers water, which is especially useful in dry locations.
What is the purpose of removing grit?
The technique of removing sand, silt, and grit from water is known as grit removal.
Grit (and sand) removal is common in wastewater treatment facility headworks (WWTP). Grit removal can be used to eliminate sand from river water before they are processed for potable water, so as to remove fine abrasives in industrial applications, and to remove grit entrained in sludge.
Technologies for removal of silt and solids
1: Screening process
The waste is washed and dewatered before being discharged into a rubbish bin by the screening system. The screened wastewater next flows to an aerated grit chamber, which reduces the velocity of the wastewater, allowing heavier inorganic elements like sand and grit to settle. The grit chamber is aerated to increase the amount of DO in wastewater, which aids the aerobic biological process in the treatment system. An auger removes the material gathered at the bottom of the grit tank and mixes it with biosolids formed throughout the treatment process.
2: Filter Press
One of the most well-known and dependable forms of dewatering equipment is the filter press. It's used to clean wastewater in a variety of industries and applications. By separating solids from liquids, a filter press eliminates contaminants and suspended sediments from industrial effluent
To separate liquids and solids, the filter press employs pressure filtration through a filter media. After that, the slurry is placed through a filter press and dewatered under pressure.
