Role of Polyelectrolytes in the Treatment of Waste Water

Wastewater is any water whose quality has been adversely affected by human activity. Wastewater can begin from a variety of sources such as residential, industrial, business, or agricultural activities, etc. It is a process that is essential to adjust the pH of the water and reduce the release of contaminants into the environment. The presence of pathogens, organic and inorganic matter, dissolved gases, paint emulsions, pesticides, bio-solids, and many more undesirable substances can impair the quality of water. 

Chemtex wastewater chemicals treat this sludge before release. The sewage sludge produced is subjected to sludge treatment. Many problems are associated with wastewater collection and treatment such as foaming, solid accumulation, high BOD, sludge de-watering, heavy metals, and offensive odors.

When using total wastewater treatment solutions, Wastewater treatment chemicals remove and eliminate harmful pathogens, expel hazardous chemicals, detergents, and toxins, reduce odour and improve watercolor, and separate and extract valuable substances and clean water from the wastewater.

Why treats wastewater?

Domestic wastewater contains a large amount of solid material, food particles, toilet paper, grease, oil, soap, salts, metal detergent, pharmaceuticals, and personal care products. Industrial wastewater is released from different commercial and manufacturing units such as textiles, printing, F&B, and production to name a few. it contains toxic chemicals, organic effluents, and harmful microorganisms. The discharge of industrial, and commercial waste into nearby water sources is another major cause of water pollution. The effects can be seen in water resources such as streams, ponds, tanks, and pipelines, which are often contaminated or polluted due to the discharge of sewage and garbage.

Different kinds of germs which cause diseases grow in polluted water. There are a number of ways in which wastewater can cause pollution problems. These water bodies are the main sources of many other domestic applications. So, Proper treatments need to be carried out before it is exposed to another body of water. Wastewater Treatment basically removes synthetic chemicals, suspended solids, metals, pathogens, dissolved minerals, etc.

Polyelectrolytes are regarded as organic polymer chains with an electrolyte group on every repeat unit. When dissolved in a polar solvent, these polymers are charged due to the dissociation of small counterions that leave behind a charged micro ion. When the electrolyte group dissociates, polymer molecules become either positively or negatively charged, depending upon the functional group. The polymer that contains negatively charged ion is called Anionic Polymer and that contain positively charged ion is called Cationic Polymer.

These are formulated in a way so as to be used as coagulants and flocculants as well as sludge dewatering agents in wastewater treatment plants.

Flocculants: Flocculants are chemicals responsible for bringing about secondary settling and sludge dewatering. They carry active groups with a charge which helps in counterbalancing the charge of the particles. Flocculants can be used in water treatment on their own or in combination with coagulants. It adsorbs on particles and cause destabilization either by bridging or charge neutralization. These may be categorized according to the charge density and molecular weight.

Coagulants: Coagulants are referred to as chemicals that are used to help in the removal of colour and turbidity present in untreated, raw water. They do this by forming settle able articles in the form of floc, which are then removed in downstream clarification or filtration treatment processes. These coagulants are either organic or inorganic based on their formulations. Organic coagulants are used for the treatment of water with low suspended solid content and they partly or completely replace the inorganic coagulants. These chemicals are appreciated for their attributes like quick flocculation, precise pH value, etc. Choosing a right coagulant ensures effective and efficient coagulation in waste water treatment.

Anionic Polyelectrolytes emerge as invaluable tools in the realm of wastewater treatment. Their role in coagulation, flocculation, settling, and dewatering processes contributes to cost-efficiency, improved environmental compliance, enhanced water quality, and streamlined process control. As the demand for sustainable water management practices continues to grow, the significance of Anionic Polyelectrolytes in transforming wastewater into a valuable resource becomes increasingly apparent. Through these innovations, we move closer to a future where wastewater is not merely treated but truly repurposed for the betterment of our environment.

The Role and Importance of Demulsifiers in Oil and Gas Industry

Demulsifier helps to extract oil and purify water, which is especially important in crude oil production and wastewater treatment.  It is a substance that separates an emulsion into components and destabilizes water-in-oil emulsions. In Crude production, Water-in-oil emulsions are typically produced, owing to the presence of emulsifying agents such as surfactants, slits, fine solids, drilling mud, clay, water, and other impurities. These impurities are undesirable need to be removed which would otherwise shackle the quality of the crude.

How does It work?

Demulsifier consists of two liquids that are not mixed with each other and tiny droplets of one liquid are evenly distributed throughout the volume of the other. This kind of liquid is called dispersion medium, and the droplets are called dispersed phase. During the demulsification process, a demulsifier accumulates on the surface of the droplets and groups them together.

The process of separating an emulsion into its constituent oil and water phases requires the disruption or destabilization of the protective film that surrounds water droplets. To break these oil–water emulsions, and ensure transfer of high-quality crude to the refinery, a demulsifier is used. The hydrophobic nature of this molecule bonds with the hydrocarbon, attacks the droplet interface, disperses or congeals into larger droplets, causing a change in density which separates the emulsion.

Demulsifiers are essential for the oil and gas industry for various reasons:

1. Enriched Separation: These are designed to destabilize and enhance the separation of oil and water, making it more efficient and cost-effective.
2. Increased Productivity: Demulsifier helps to boost production rates, by accelerating separation process.
3. Cost Effective: Efficient demulsifier reduces the need for expensive equipment and energy-intensive processes.

The role of Demulsifiers cannot be underestimated in improving the efficiency of crude. This chemical plays a crucial role in breaking down emulsions, ensuring that the valuable crude oil is separated from water effectively. Sustainable and efficient oil and petroleum production processes will be achieved as demulsifiers will continue to be developed and refined.

Demulsifiers come in various formulations, each tailored to specific emulsion challenges and environmental conditions.

As the industry evolves, demulsifiers will continue to be refined and developed, contributing to more efficient and sustainable oil and gas production processes.

The Use & Benefits of Ro Antiscalant in RO Plant

Water is one of the important resources, and ensuring its purity and availability is crucial for both industrial and domestic use.

Reverse Osmosis Technology plays a vital role in the removal of impurities such as salts, minerals, and other contaminants from water for various applications, including drinking water, industrial processes, and boiler water treatment. The RO membrane is the heart of the RO System designed with a dense, thin, and semi-permeable layer that allows water molecules to pass through while rejecting dissolved solids and other contaminants. The RO Membrane operates under high pressure and requires continuous cleaning and maintenance to prevent fouling and scaling.

What Causes the formation of scales in RO membranes?

The level of hardness salts present in the feed water is the foremost reason. When such feed water passes through the RO Membrane, the concentration of these salts gets precipitated over the surface of the membrane. Overtime deposition of such salts from scales. This scale formation reduces the effectiveness of the membrane, which ultimately decreases the flow rate of water. In smaller systems, scale formation can be prevented by the exchange softening process but in larger systems, it becomes expensive.

RO Antiscalant – Cost Effective Solution

RO Antiscalant known as scale inhibitors are essential components in water treatment processes, these are designed to prevent precipitation and accumulation of scale-forming minerals such as calcium carbonate and calcium sulphate, on the surface of RO Membranes. It becomes essential to maintain the long-term performance and reliability of the RO membrane.

How it works?

RO Antiscalant works by altering the chemical environment of the feed water in a way that inhibits the formation and growth of scale-forming minerals. They work by interfering with the crystallization process of scale-forming minerals, keeping them in suspension and preventing them from adhering to the membrane surface.

Selecting the appropriate RO antiscalant is essential to maximize its benefits. Chemtex manufactures its antiscalant for Reverse Osmosis (RO) Systems, depending upon the type of membrane, quality of feed water, and rate of product recovery.

• Neutral RO antiscalant reduces membrane fouling within separation systems, effectively controlling inorganic salts, metal hydroxides, and colloids in RO feed water.
• Low pH RO antiscalant eliminates inorganic scales in multiple application areas. It stabilizes metal ions to prevent metal oxide precipitation and disperses silt and clay particles.

Key Features & Benefits

• Excellent scale inhibition
• Reduced membrane cleaning
• Compatible with all types of membranes
• Eco Friendly and Biodegradable
• Maintain the correct pH levels
• High recovery rate with low dosage

Role of Polyelectrolytes in Wastewater Treatment

Effluent Treatment or Industrial wastewater treatment consists of mechanisms and processes which are used to treat water that have been contaminated by anthropogenic, industrial or commercial activities prior to its release into the environment. Industrial wastewater serves as one of the important pollution sources that add up in polluting the water environment. The sewage sludge produced is subjected to sludge treatment. Many problems are associated with wastewater collection and treatment such as foaming, solid accumulation, high BOD, sludge de-watering, heavy metals and offensive odour.  But such treatments are no more complicated processes, since there are chemicals that are applicable for the treatment. These chemicals follow various treatment mechanisms in various different standards, which include from chemically treating raw wastewater before discharging it into the environment, to recovering valuable resources from sludge treatment and wastewater.

Conventional treatment consists of a combination of physical, chemical, and biological processes for removal of suspended solids, organic & inorganic contaminants, germs and microbes from wastewater. When using total wastewater treatment solutions, these chemicals remove and eliminate harmful pathogens, expel hazardous chemicals, detergents and toxins, reduce odour and improve water colour, and separate and extract valuable substances and clean water from the wastewater.

Polyelectrolytes are regarded as polymer chains with an electrolyte group on every repeat unit. When dissolved in a polar solvent, these polymers are charged due to dissociation of small counter ions that leave behind a charged micro ion. These are formulated in a way so as to be used as coagulants and flocculants as well as a sludge dewatering agent in the waste water treatment plants. Flocculants are chemicals responsible for bringing about secondary settling and sludge dewatering. They carry active groups with a charge which helps in counterbalancing the charge of the particles. Coagulants are referred to as chemicals that are used to help in the removal of colour and turbidity present in untreated, raw water and are used for their attributes like quick flocculation, precise pH value, etc.

Based on electrolyte group present in the chain, polyelectrolytes are categorized into anionic, cationic and non – ionic species. Cationic polyelectrolytes have positively charged group for use in coagulation of negatively charged flocs through electrostatic interactions. They are useful in various process of effluent r wastewater treatment, depending upon their molecular weight and charge density. Anionic polyelectrolytes have negatively charged group on each repeating unit, acrylamide-based polymers being the most available type. They are widely useful as flocculants, rheology modifiers, and adhesives and immensely used in municipal wastewater and effluent treatment. Anionic flocculants are also used in enhanced oil recovery, decolouring, paper making, mineral processing, etc. Non – Ionic Polyelectrolytes are organic high molecular weight polymers, used in flocculating colloidal suspensions, water clarification, sludge dewatering, etc.

In general, aqueous solutions having pH value more than 4 have negative charged suspended particles whereas having pH less than 4 contains positively charged suspensions. This might help in analysing the type of polyelectrolyte to be used in the treatment.
