Waste water treatment is essential to ensure that water from various sources, such as households, businesses, and industries, is purified and safe for release into the environment. Each piece of equipment collected serves a specific purpose in cleaning or improving water quality. The blog post covers the different types of waste water treatment equipment, their purposes, and how they interact with the overall treatment process.
1. Screening Equipment
Because screening devices remove a significant proportion of trash and particles from wastewater, they are regarded as the initial step in the treatment process. Microscreens, fine screens, and coarse screens are a few popular screen kinds in use. Large objects like sticks and plastic bottles are captured by the coarse screens, while grit and sand are captured by the fine ones. Microscreens are employed for even tinier particles.
2. Grit Removal Systems
Grit removal systems primarily remove sand, gravel, and other heavy inorganic elements from wastewater. The operation prevents the destruction of these materials by the rest of the equipment, which, given their abrasive nature, reduces their accumulation within the treatment plant, increasing efficiency. One major system is the aerated grit chamber, while another is the vortex-type grit removal unit.
3. Sedimentation Tanks
Sedimentation tanks, more commonly known as clarifiers, allow suspended solids to settle out of wastewater. There are primarily two types of clarifiers: primary and secondary. Primary clarifiers remove large settleable solids, while secondary clarifiers deal with smaller particles remaining after biological treatment.
4. Disinfection Systems
Disinfection systems play a significant role in killing most of the dangerous microorganisms present in treated wastewater. Common techniques for disinfection include chlorination, the use of ultraviolet radiation, and ozonation. Chlorination works by adding chlorine to the water, while UV radiation uses UV light to kill the microorganisms. Ozonation requires that ozone gas, which is a very good disinfectant, be used.
1. Advanced OXIDATION PROCESSES (AOPS)
AOPs are a diverse group of strong oxidants that decompose the complicated organic molecules in wastewater in conjunction with advanced oxidation. They entail ozonation, Fenton's reagent, and photocatalysis. AOPs have been able to remove refractory organic compounds very effectively and produce better water quality.
2. Ion-Exchange Systems
Ion exchange systems remove dissolved ions from wastewater, which may include heavy metals and salts. Their applications involve resin beads exchanging undesirable ions with more acceptable ones. The most typical sector that applies this technology is in industries where water quality cannot be compromised, such as the pharmaceutical or high-technology electronic industries.
3. Electrocoagulation
Electrocoagulation uses electrical currents to destabilize and further coagulate suspended solids, oils, and heavy metals in the wastewater. This process is quite successful in industrial waste water treatment; however, it can be used in conjunction with other treatments for better results.
