sludge density prediction in a wastewater chemical coagulation process

[PDF] Sludge Density Prediction in a Wastewater Chemical

predict in a simple way the amount of sludge produced from simple routine procedures such as determining SST, and dry sludge. This work is an approach to correlate SST and dry sludge amount in order to predict sludge density based on applied coagulant concentration. 2. Methodology . 2.1. Reagents .

Sludge Density Prediction in a Wastewater Chemical

This paper reports an approach to estimate the sludge density in a physicochemical treatment of municipal wastewater, experiments considered 4 coagulants (aluminum sulfate SAl, iron sulfate SFe, aluminum polychloride PAX, iron polychloride PIX), and 2 flocculant products (cationic CP and anionic AP polymers).

Evaluation of chemical sludge production in wastewater

The results indicated that the chemical sludge production increased linearly with the coagulant dosage, with sludge production values of 0.49–0.82 mg/mg FeCl 3 for the aerobic effluent and 0.40–0.64 mg/mg FeCl 3 for the anaerobic effluent. These values were expected according to the theoretical stoichiometry of the reactions involving the

Chemical Coagulation - an overview | ScienceDirect Topics

Electrocoagulation produces about half the sludge of chemical coagulation. Rigorous legislation is now in effect in several countries to limit the impact of such residuals on the environment. Wastewater sludge is generally characterized by BOD concentrations in the hundreds and COD concentrations in the thousands of mg L ? 1 [6].

Role of electrocoagulation in wastewater treatment: A

Chemical coagulation is the second step in wastewater treatment [1,2]. This process has a signi?cant in?uence on the properties and structure of the resulting sludge [3–7]. The pH of sludge decreases during chemical coagulation because Fe3+ or Al3+ undergoes cationic hydrolysis and its ?rst stage can be described as follows:

1. Introduction Coagulation is one of the most common phenomena in nature and artificially enhanced water treatment systems. Coagulation is a process in which small particles are combined into larger aggregates (flocs) and dissolved organic matter is adsorbed onto particulate aggregates so that these impurities can be removed in the subsequent solid/liquid separation processes. 1 The mechanism

Wastewater treatment - Sludge, Disposal, Treatment | Britannica

Sludge digestion is a biological process in which organic solids are decomposed into stable substances. Digestion reduces the total mass of solids, destroys pathogens, and makes it easier to dewater or dry the sludge. Digested sludge is inoffensive, having the appearance and characteristics of a rich potting soil.
