In coagulation, Alum (Al2 (SO4)3.18H2O) was used as a coagulant. Alum is one of the raw materials used by paper mill therefore its selection was preferred for treatment of wastewater.
The 'challenge doses' used were: For lethality, four Median Lethal Doses (LD50s); for hemorrhage, five Minimum Hemorrhagic Doses (MHDs); for defibrinogenation, two Minimum Defibrinogenating Doses (MDDs); and for in vitro coagulation, two Minimum Coagulant Doses (MCDs).
The coagulant B is phenolic resin produced by the condensation reaction of formaldehyde and phenol, and its chemical structural formula is as follows:
In this context, the proposed system employs a multilayer perceptron network particularly designed to determine the best coagulant dosage at two distinct sites of the water treatment plant, especially by using two additional dose rates as inputs for neural network, to guarantee the best performance for the filtration stage.
The effectiveness of iron (III) sulphate (VI), irrespective of the type of polluted water (raw or aerated water), was only greater than that of the aluminium coagulant of aluminium sulphate (VI) (SAL) in reducing the turbidity and removing the manganese compounds, and even greater than PAX XL-60 coagulant.
The main objective of the study are: Treatment of Textile Dying industry effluents with Cotton fiber to optimize the coagulation process for various coagulants i.e., Ferrous Sulphate (FeSO4.7H2O), Lime (CaO) and Alum (KAl(SO4)2.12H2O) in terms of process conditions, including coagulant dose, pH and settling time, to apply the advanced oxidation process including Ozonation process, and Fenton alone and in combination to treat the effluent, and to determine the effects of process conditions such as Ozone dose, initial dye contents, iron catalyst concentration, Hydrogen Peroxide (H2O2) concentration, pH treatment time and settling time on the overall efficiency of these processes.
The most important factors affecting the efficiency of coagulation process are PH, ions in aqueous solutions (strength of water's ion), humic substances concentration, water temperature and the type of coagulant (UNESCO, WHO and UNEP, 2000).
Delvo[R]Cheese CP-200 used in combination with the coagulant Maxiren[R] XDS further enhances the flexibility in both production and processing.
To remove turbidity in water treatment, nature of suspended materials in water is critically important for determining the coagulant. Coagulation is the process requiring the largest share of costs of water treatment operation.
It can be expressed as the conversion of colloidal and dispersal particles into small visible floc upon addition of a simple coagulant. It brings about compression of the electrical double layer surrounding each suspended particle, as a result of decrease in the magnitude of the repulsive interactions between particles and destabilization of the particles.
As a coagulants alum (KAl(SO4)2 * 12 H2O) and natural coagulant from common bean seeds were considered.
Currently, there are several chemicals that been conventionally and commercially used as coagulant in the water and wastewater treatment.
The suspensions were stirred for 15 min at room temperature (25 [degrees]C [+ or -]2) to extract the coagulant proteins and then filtered through a fine fiber material to obtain the CSEs.
