Removal of dissolved humic acid from water by coagulation method using polyaluminum chloride (PAC) with calcium carbonate as neutralizer and coagulant aid

Abstract

The increasing global competition within today's manufacturing industries is confronting organizations with interdisciplinary challenges that require intellectual expertise and innovative technological solutions in various knowledge areas. Research organizations and manufacturing companies can improve their overall performance by bundling expertise in collaborative innovation networks. For this purpose a systematic Benchmarking approach has been developed by Fraunhofer IPK to match the competencies and capacities within a pool of organizations in order to facilitate a sustainable cooperation in terms of resources, customers and R&D topics. Furthermore, a KPI-based identification of best performing network-partners allows an initiation of Best-Practice transfers to gain sustainable competitive advantages for the whole network. Based on a methodological approach, the identification of collaboration potentials and Best-Practices is supported by software tools that visualize the results in an understandable and applicable way.

Performance evaluation and antifouling analyses of cellulose acetate/nanodiamond nanocomposite membranes in water treatment

“…According to the results reported by Sudoh et al ., in comparision with aluminum sulfate (AS) and ferric chloride (FC), polyaluminum chloride (PAC) shows better efficiency of coagulation agents in HA removal. They concluded that PAC has large molecular weight, and therefore, it produces a huge amount of aluminum hydroxides.…”

Electrocoagulation and ultrasonic removal of humic acid from wastewater

“…They are able to react with chlorine and produce harmful compounds in water and make complex with heavy metals in water . Different tertiary methods such as active carbon adsorption , coagulation , membrane filter , sonochemical , photo‐Fenton process , and electrochemical oxidation are used by researchers to remove HAs compounds from wastewater. These processes are not attractive for industrial‐scale application because of high capital and operation costs.…”

Finding the Reaction Constant Between Humic Acid and Metal Ions by Fluorescence Quenching Effect

“…In drinking water treatment, polyaluminum chloride, aluminum sulfate and ferric chloride are commonly used metal salt coagulant. Many studies have proposed that coagulation procedures can be used to remove humic acid [1]. Humic acid contains an aromatic heterocyclic structure.…”
