Coagulation Dosage - Water Treatment Process & Plant Design
In bulk water treatment, the jar tests are repeated with varied alum dose until the ideal dose is found. The needed dose varies with the pH of the water and the size of the particles. The usual range of alum dose is 10 to 50 mg/L of water. FEEDING DEVICES; A well engineered feeding device is an integral part of an effective water treatment program.
The process of consolidation of colloidal particles by neutralizing the charges with a coagulant, so that they can remove from the treated water by sedimentation or filtration is called coagulation. It is a vital part for drinking water and wastewater treatment. Coagulants. Coagulants are the chemicals that are used to removes tiny particles in water.

Water Treatment Coagulants. Coagulant water treatment chemicals come in two main types – primary water treatment coagulants and coagulant aids. Primary coagulants neutralize the electrical charges of particles in the water which causes the particles to clump together.
Flocculation and coagulation treatment chemicals are used in effluent wastewater water treatment processes for solids removal, water clarification, lime softening, sludge thickening, and solids dewatering.. Coagulation treatment neutralizes the negative electrical charge on particles, which destabilizes the forces keeping colloids apart.
Enhanced water treatment by Moringa oleifera seeds extract
Moringa oleifera is a tropical plant belonging to the family of Moringaceae.Its seeds have been shown to be one of the most effective main bio-coagulants for water treatment, including the turbidity of surface water, alkalis, organic contaminants through biological oxygen demand (BOD 5), chemical oxygen demand (COD) in municipal wastewater, and industrial wastewater including textiles
