The process makes use of a
flocculation tank channel, which mixes chemicals with the water to enhance the formation of larger particles or flocs that could be easily be separated from the water.
Pigment
flocculation contributes to cell formation and flooding/floating because it encourages separation of pigments that are flocculated from those that are not, particularly if the latter has small particles that are more easily trapped at the surface.
Among his topics are the origin of charge at interfaces and structure of the electrical double layer, Van der Waals attraction, the adsorption of surfactants at the liquid/liquid interface, polymers and polymeric surfactants and their association, and the
flocculation of sterically stabilized dispersions.
Recently, many investigations such as membrane [4], electrochemical oxidation [5], and
flocculation [6] have been explored for the purpose of reducing the quantity of kaolin produced by wastewater and improve the quality of the treated effluents.
The dye was removed due to the interaction with the polysaccharide starch and
flocculation phenomenon.
Such methods include
flocculation, flotation, electro-flocculation, membrane filtration, coagulation, electrochemistry, ion exchange, precipitation, radiation, ozonisation, among others (Srinivasan & Viraraghavan, 2010).
The surface water received at the Simly and Khanpur treatment plants, passes through
flocculation, sedimentation, filtration, disinfection before reaching the consumers, he added.
There are several methods available for COD removal from wastewater i.e., electrochemical Fenton process,
flocculation and advanced oxidation processes, activated carbon and low cost adsorbent (Eslami et al., 2013; Lakdawala and Lakdawala, 2013; Hussain et al., 2013; Rakholiya and Puranik, 2012; Aluyor and Badmus, 2008; Zayas et al., 2007).
Chain-like
flocculation comes into being, and then network structures are formed in the entire liquid.
This leads to the loss of pigment stabilization and
flocculation of the colorant or paint pigments leading to an immediate or gradual change in color (Figure 1).
