Question

What is a use loading tank in water purification

Answer 1

• Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from water.
• The goal is to produce water fit for a specific purpose. Most water is disinfected for human consumption

but water purification may also be designed for a variety of other purposes, including fulfilling the requirements of medical, pharmacological, chemical and industrial applications.The methods used include physical processes suchas-

• filtration,
• sedimentation,
• distillation
• biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.
• The process of filtration of water includes the following methods

1. Sedimentation tank
2. Loading tank
3. Chlorination tank
4. Filtration tank

loading tank

• The addition of inorganic coagulants such as alum or iron salts such as iron chloride course several simultaneous chemical and physical interactions on and among the particles within seconds negative charges on the particles are neutralized by in organic coagulants also within seconds metal Hydroxide precipitates of the aluminium and iron begin to form
• These precipitates combine into larger particles under natural process such as Brownian motion and through induced mixing which is sometimes referred to as flocculation
• the term most often used for the amorphous metal hydroxides is ''floc"' Large amorphous aluminium and iron Hydroxide absorb the particles in Suspension and facilitate the removal of particles by subsequent process of sedimentation
