Coagulation and Flocculation in Wastewater Treatment

 

Industrial wastewater contains higher levels of suspended solids and organic materials. These suspended solids are stabilized by negative electric charges, causing them to repel each other. Rather than settling, these particles are kept in suspension by repulsion. In such cases, chemical treatment is required to neutralize the charges on colloidal particles, as the solids cannot be separated easily with conventional filtration or settling methods. On chemical dosing, mainly polyelectrolytes, there undergo two very basic working mechanisms i.e., coagulation and flocculation.

Coagulation is the neutralization of charges on suspended particles, leading to their destabilization and subsequent aggregation. Flocculation helps to fill the gaps between the destabilized particles, allowing them to make larger, denser flocs, which can be easily separated from the treated water through sedimentation. The efficiency of this process depends upon the coagulant type, dosage, pH value, temperature, nature, the concentration of organic matter, and distribution of colloidal particles in suspensions. The benefits of coagulation and flocculation are numerous. They effectively remove suspended solids, organic matter, inorganic compounds, and microorganisms from wastewater and minimize the impact on the environment.



Some of the major impacts, these processes have on water treatment.

·         Removal of suspended solids – The primary purpose is to remove suspended solids, resulting the clear effluent.

·         Contaminants removal - The coagulants bind with these contaminants, allowing them to be captured and removed during subsequent treatment steps.

·         Enhanced Treatment Efficiency –This indispensable Process enhances the overall efficiency of wastewater treatment by reducing the load on downstream processes.

·         Phosphorus Removal - It is a critical environmental concern, and is efficiently addressed through the process.

·         pH Adjustment – It is necessary for water treatment to optimize the performance of coagulant and flocculant polyelectrolytes

Wastewater treatment deals with the processes required to decrease contaminant levels present in the water before its disposal in the environment, depending upon the source of water and geographical conditions. We are witnessing a lot of implementations of physicochemical processes which handle wastewater starting from simple removal of suspended matter to cleaning of RO membrane systems. The process may range from simple sedimentation and decantation to the use of UV technology, depending upon the type of level of contamination. The treated wastewater can be used for agriculture, soil conditioning, energy generation, etc.

H2S – A Silent Ultimatum to Oilfields

H 2 S Scavenger Chemical – Introduction The world has witnessed a substantial increase in E&P of crude oil to meet the need for globalization, leading to drilling of ‘deemed undesirable’ sites, owing to the presence of higher concentration of acidic gases like hydrogen sulphide, carbon dioxide, etc. These hazardous gases require proper measures before disposal or scavenging. Of these, Hydrogen sulphide/ H 2 S is the most threatening one, especially in confined or ill ventilated places. The characteristic rotten egg smell makes H 2 S recognition easy even at lower concentrations. Hydrogen Sulphide is toxic, acidic and extremely corrosive at higher concentrations. Heavier than air, it is found more near base level of the working sites. Then comes its inflammability, which may cause explosive reaction with air molecules. With peroxides, ammonia and other oxidizing chemicals, H 2 S often goes through combustible reactions, ...

Acid Corrosion Inhibitor – Chemtex Speciality Limited

  Acid Corrosion Inhibitors are the most important inhibitor of any operation, preventing the impact of corrosion on exposed metal, tubular, downhole equipment, and surfaces and maximizing longevity, minimizing the operational cost. Corrosion is the chemical interaction with the environment that cause the deterioration of materials and it is unavoidable for all metals. When acids come into contact with metals, they initiate chemical reactions that lead to corrosion. Acid corrosion inhibitors work by forming a protective layer on the metal surface, which acts as a barrier against the corrosive acids. This layer prevents direct contact between the acid and the metal, thus inhibiting the corrosive process. Mechanisms of Acid Corrosion Inhibition Acid corrosion inhibitors work by forming a protective layer on the metal surface, which acts as a barrier against the corrosive acids.
