Chemical-Aided Sedimentation of Sewage | Waste Management

Chemical-aided sedimentation of sewage is analogous to chemical coagulation, flocculation and sedimentation in water treatment. The colloidal and finely dispersed solids which cannot be removed by plain primary sedimentation alone, as they possess extremely low settling velocities, are aggregated into settleable particles by addition of chemicals known as coagulants in chemical-aided sedimentation. Chemical-aided sedimentation involves the unit processes and operations [...]

High Strength Concrete and Its Production | Concrete Technology

Generally concrete is classified as Normal strength concrete (NSC), High strength concrete (HSC) and ultra-high strength concrete (UHSC). However there is no clear cut boundary for the classifica­tion. Indian Standard for mix design has suggested the boundary at 35 MPa (350 kg/cm2) between Normal and High strength concretes. However no boundary has been fixed between High strength concrete and ultra-high [...]
