The higher the temperature, the faster the reaction, and the more effective is the coagulation. Winter temperature will slow down the reaction rate, which can be helped by an extended detention time. Mostly, it is naturally provided due to lower water demand in winter. Coagulation for color reduction is normally carried out at pH 4.5 to 5.5. Optimum pH for turbidity removal is usually much higher than that for color reduction. The presence of sulfate ions can interfere with coagulation for color reduction, whereas calcium and magnesium ions can improve the process and broaden the pH range in which color may be reduced effectively.

Jar test is an experiment to understand the processes of coagulation, flocculation and sedimentation (AWWA, 2011). Jar test apparatus consists of six batch beakers, and equipped with a paddle mixer for each beaker. In a standard practice, jar test involves rapid mixing, followed by slow mixing and later the sedimentation process.

These are the contact activation pathway (also known as the intrinsic pathway), and the tissue factor pathway (also known as the extrinsic pathway), which both lead to the same fundamental reactions that produce fibrin. blood coagulation (clot formation), which causes blood to solidify; clot resolution, which returns blood to the fluid state. In many clinical situations, drugs are used to slow or stop this pro­cess, with the goal of preventing tissue damage from the decreased blood flow that occurs when the clotting process cuts off blood supply to an area.
