What are the factors on which dose of coagulants depends? Explain how the optimum coagulant dose is determined?
Answers
The quality factor or the Q factor of an inductor at the operating frequency ω is defined as the ratio of reactance of the coil to its resistance. Thus for a inductor, quality factor is expressed as, Where, L is the effective inductance of the coil in Henrys and R is the effective resistance of the coil in Ohms.
Answer:
The coagulants depend on the mass and the pH value of the dosage given it also depend on the amount of charge that relies by the electrolyte.
Explanation:
coagulation is a chemical process that does. Coagulation-flocculation can be employed as an initial step before additional water or wastewater treatment procedures like filtration and sedimentation, or as an interim phase between them.
The amount of charge that an electrolyte's effective ion has relies on the coagulating power of the electrolyte. Coagulation is influenced by the coagulant's mass, dosage, and type. Additionally, initial turbidity, TDS, pH, and any contaminants in the water. Oxidation is another factor that can influence how well the coagulation process works.
A coagulated particle may redispersion under high pH conditions, whereas a pH that is too low may prevent the coagulation process from moving forward. The pH also influences the size of the coagulated particles, which in turn affects the density of the flocculated slime as well as its tendency and rate of settling out.
pH and dosage are two crucial elements in the addition of coagulants. Laboratory studies are required to determine the ideal dosage and pH. The ideal pH range for alum is roughly between 5.5 and 6.5, with acceptable coagulation under some circumstances being feasible between pH 5 and pH 8.
