Abstract

In the application of coagulation and flocculation process in the wastewater treatment, the laboratory activities are very important and sometime even indispensable. These activities provides some solutions to the efficiency that can be obtained and offer the possibly of results extrapolation to the industrial applications. The present study attempted to verify some possible laboratory application of the Acefloc organic flocculants series to the municipal waste leachate treatment. In these sense, some laboratory techniques were implemented to evaluate de flocculants efficiency by analyzing some quality parameters. In the case of Acefloc 00303L flocculants use were obtained the best performances regarding the analyzed quality indicators reduction. By using the flocculation process, the COD concentration decrease with 85.35 % in the case of Acefloc 00303L flocculants use

Highlights

The flocculation processes applied in wastewater treatment to separate the destabilized colloid particles by forming flocs [1,2,3,4,5,6,7,8]
Synthetic flocculants are obtained by monomers polymerization
The synthetic flocculants are made from different types of monomers such as acrylamide, acrylic acid, ammonium chloride, styrene sulfonic acid etc

Summary

Introduction

The flocculation processes applied in wastewater treatment to separate the destabilized colloid particles (or the particles formed during the coagulation phase) by forming flocs [1,2,3,4,5,6,7,8]. In wastewater treatment processes the flocculation process is applied only when the particles have been destabilized. In many wastewater or sludge treatment processes are used synthetic organic flocculants due to its advantages creates respectively waters with low solids suspension concentrations and weak solutions [1,2,3,4,5,6,7,8,9,10]. The acrylamide is a crystalline and stable monomer, soluble in water [4,5,6, 11]
