Turbidity is a principle physical characteristic of water. It is caused by suspended matter or impurities that interfere with the clarity of the water. These impurities may include clay, silt, finely divided inorganic and organic matter, soluble A Study on the Use of Alum for Turbidity Removal in Synthetic Water
Representative jar testing means that the jar test procedure will imitate the coagulation, flocculation, and settling conducted in the water plant. There is no single jar test procedure will duplicate all of these processes for all plants, however, experience shows that jar test procedures can be individually tailored to accuray

O in a granular form was used as coagulant, and it was applied in samples in liquid form, this is why its preparation was necessary at a concentration of 5000 mg/L, in which 1ml applied on a sample of 500 ml represents a concentration of 10 mg /L. 2

3.1. Reduction of Turbidity Using Alum Only In order to find the optimum dose for the synthetic water, jar test operations using Alum coagulant were carried out twice (sample A and sample B) for the two different turbiditys which are they: high (90 - 120) NTU and low (20- 35) NTU of sy n-thetic turbid water. 3.1.1.

The results of series 1 jar test have been graphically presented in Fig. 1, Fig. 2, Fig. 3, Fig. 4. Fig. 1 shows the residual turbidity using alum with and without the use of It is evident from the figure that turbidity removal was enhanced by the use of

Jar test was cond ucted to determine the pH and Alum optimum values, in the presence of turbidity and heavy metals. Optimum pH was determined by fixing the Alum concentration and ranging the
A study was conducted to treat the tannery wastewater through coagulation-flocculation-sedimentation. Alum was used as coagulant with cationic and anionic polymers as coagulant aid. The results were subsequently compared with the study in which alum was used alone for the treatment. Jar test apparat

The jar test method was used for the study of coagulation–flocculation. A conventional jar test apparatus (SLOTEQ flocculation test unit, Model TR10) was employed for the test. It had six stirrers and every stirrer was controlled individually. The determination of any effect included use of a

Laboratory jar test studies were carried out using either an orthophosphate solution (10 mg l-1) or a tannic acid solution (50 mgC l-1) as simulated wastewater and the effect of parameters such as coagulant dose (up to 15 mg Al l-1 in the case of alum and up to 90 mg Al l-1 in the case of
