What is flocculation?
Flocculation is the process by which colloidal particles come out of suspension to settle as floc or flake, either spontaneously or as a result of the addition of a clarifying agent. Prior to flocculation, colloids are simply suspended in a stable dispersion, where the internal phase (solid) is dispersed throughout the external phase (fluid) through mechanical agitation, but are not truly dissolved in solution, as opposed to precipitation.
Coagulation and flocculation are important processes in water treatment, with coagulation aiming to destabilize and aggregate particles via chemical interactions, between the coagulant and colloids, and flocculation aiming to sediment the destabilized particles via flocculation.
What is a Sustainable flocculation?
A flocculation process is used in most standard drinking water and wastewater treatment systems, to reduce the concentrations of solids in the effluent stream. This method employs substances, which aid in the clumping of suspended particles and other contaminants, in a clarifier system.
Sustainable flocculation entails the use of a bio-organic flocculant that is organic in nature, and is not primarily composed of conventional metal salts or synthetic substances. This enables optimized dosing with enhanced treatment, for cleaner and greener water and wastewater.
Furthermore, improved sludge dewatering and reduced amounts of non-toxic sludge, results in significantly lower disposal costs with minimal environmental impact.
What are Sustainable Biopolymer Flocculants?
Sustainable biopolymer flocculants are natural polymers produced by living organisms' cells. These are typically classified as natural flocculants.
Biopolymers are classified into three types. These classes are defined by the biopolymer structure and the monomers used. Polynucleotides, polypeptides, and polysaccharides are the three classes.
Difference between a natural polymer and a synthetic polymer
The primary distinction between biopolymers and synthetic polymers can be found in their structures. All polymers are made up of repetitive units known as monomers.
Many natural biopolymers instinctively bend into distinctive compact shapes, which determine their biological activities and are intricately dependent, on their primary structures.
In comparison, most synthetic polymers are typically derived from petroleum-related products, with simple but random structures created in laboratories.
What are sustainable flocculants made of?
They are made of natural and eco-friendly materials, as well as bio-polymers. Its constituents have exceptional adsorption and cation exchange properties.
Polymers are well known in water treatment for their ability to bind. These sustainable liquid flocculants have the affinity for certain trace heavy metals, organic compounds, TOC, color, and suspended solids, as well as lowering COD and BOD levels in wastewater sources. Because, of its environmentally friendly composition and sheer strength, the formed particle agglomerations remain stable.
Due to rising environmental concerns, a greater emphasis on public health, and sustainability initiatives, sustainable water treatment solutions are becoming more popular than ever. In addition, the Government is enforcing stricter regulations.
Netsol Water rovides sustainable flocculation processes. Because, of their renewability, availability, and inherent biodegradability, flocculants derived from biomass sources, such as cellulose, proteins, offer a promising technological alternative to clean, and sustain industrial tailings management.
