Water Treatment Coagulation | Water Treatment | Waste 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.

What Is Coagulation and Flocculation in Wastewater Treatment?

It's what our blood does when it combines with oxygen, thereby making a scab or a blood clot. It's the same principle with wastewater treatment. In coagulation treatment, a harmless chemical such as alum causes all of the particles to give off a positive charge and thus clump together, making them easier to filter.

Coagulation Dosage | Water Treatment | Waste Water Treatment

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.

PDF COAGULATION AND FLOCCULATION – MRWA.com

Groundwater and surface water contain both dissolved and suspended particles. Coagulation and flocculation are used to separate the suspended solids portion from the water. Suspended particles vary in source, charge, particle size, shape, and density. Correct application of coagulation and flocculation depends upon these factors.

Coagulation water treatment process | Hard and Soft Water

The optimum pH for alum coagulation is 6 to 7.5 whereas 5.0 to 8.0 are for iron. If the alkalinity is lower or higher, then the floc does not form properly. As a result, more coagulant is consumed. In this case, it is beneficial to correct the pH by adding acid or base. Temperature. Temperature is another factor for coagulation water treatment process.

Coagulation (water treatment)

In water treatment, coagulation flocculation involves the addition of compounds that promote the clumping of fines into larger floc so that they can be more easily separated from the water. Coagulation is a chemical process that involves neutralization of charge whereas flocculation is a physical process and does not involve neutralization of charge. The coagulation-flocculation process can be used as a preliminary or intermediary step between other water or wastewater treatment processes
