Coagulation and Flocculation Water Treatment Specialists

Gpc Clear Solutions are Coagulation and Flocculation Water Treatment Specialists https://youtu.be/U_LVYZHrhbU Emulsion and powder flocculants At GPC Clear Solutions Limited, our highly efficient coagulants and flocculants are designed for solid-liquid separation of suspended solids in wastewater. Chemical coagulation and flocculation are effective in the removal of suspended solids in wastewater. During the solid-liquid separation process, coagulants are added which destabilises the colloidal suspension. Flocculants are then introduced to collect the coagulated solids resulting in larger flocs of suspended solids content in the wastewater. The larger flocs separate resulting in clear water. The majority of these chemicals added to the process do not stay in the aqueous phase. They are attached to the solids that are further processed and removed from the treatment area. Our high standard chemicals come in various grades and forms which are available for use depending on the application. Anionic emulsion grade polymers A range of high molecular weight anionic water in oil emulsions. These products are suitable for inline dilution before being added...

What chemicals are used in an Effluent Treatment Plant?

What chemicals are used in an Effluent Treatment Plant?

What chemicals are used in an Effluent Treatment Plant? One form of wastewater treatment is to use an Effluent Treatment Plant; this method is used to purify industrial wastewater for its reuse and safe release into the environment. Industrial effluents contain various materials depending on the industry.  One of the main contributing factors to Industrial wastewater charges are the quantity of Chemical Oxygen Demand (COD) and Suspended Solids (SS) present in the effluent. Some effluents contain oils and grease, and some contain toxic materials (e.g. Cyanide). Effluents from food and drink factories contain degradable organic pollutants whilst effluents from metal plating factories contain inorganic pollutants.  This means that all effluents and wastewater streams are different and contain a diversity of impurities and therefore site-specific chemical treatment is needed. The Effluent Treatment Plant needed for each process can greatly vary as every effluent behaves differently.  Effluent that naturally floats will require chemicals and equipment that aids this, e.g. DAF plant. Conversely, Effluent that...

What Is Polyacrylamide

What Is Polyacrylamide

What is Polyacrylamide? Polyacrylamide otherwise known as PAM is an organic polymer formed from acrylamide sub-units. It has many uses and is known throughout many industries or its versatility and quality, but one of the main purposes is in the separation of solids/liquids in the municipal and industrial wastewater sectors. Initially, it is produced with a simple, repeating, linear chain structure, but can be modified to form highly structured, branched and cross-linked variants. As part of the manufacturing process, the ionic characteristics of the polymer can be manipulated to achieve varying degrees of anionic (negative charge) or cationic (positive charge) qualities and non-ionic (minimal charge), which is a key factor during the polymer selection process. Uses: Polyacrylamide is used to flocculate solids in a liquid. This process applies to water treatment and processes like papermaking and screen printing. Polyacrylamide can be supplied in a powder or liquid form, with the liquid form being sub-categorised as a solution and a white emulsion polymer. The nature of...

What Are Phosphates In Water Treatment

What Are Phosphates In Water Treatment

What are Phosphates? Enhanced biological phosphorus removal (EBPR) is a sewage treatment configuration applied to activated sludge systems for the removal of phosphate. The common element in EBPR implementations is the presence of an anaerobic tank (nitrate and oxygen are absent) prior to the aeration tank. Phosphorus removal processes Removing phosphorus from wastewater involves the incorporation of phosphate into Total Suspended Solids and the subsequent removal from these solids. Phosphorus can be incorporated into either biological solids for example microorganisms or chemical precipitates. Phosphate precipitation Chemical precipitation is used to remove the inorganic types of phosphate by the extension of a coagulant, and a mixing of wastewater and coagulant. The multivalent metal ions most commonly used are Aluminium, iron and calcium. Aluminium and Iron: Alum or hydrated aluminium sulphate is widely used precipitating phosphates and aluminium phosphates (AlPO4). The primary reaction is: Al3+ + HnPO43-n ↔ AlPO4 + nH+ This reaction is knowingly simple and must be considered in the light of the many challenging reactions and their associated...

What Is Coagulation In Wastewater Treatment

What is Coagulation in wastewater treatment? how can flocculants and coagulants help your business? How can they save you potential fines and help you stay compliant? Have a read of our article and get in touch with our team who will be happy to answer any questions. Coagulation and flocculation describe the chemical process of contact and adhesion whereby the particles of a dispersion (colloids) form a larger-size cluster (flocs or flakes) allowing them to be more easily removed from water (e.g. by settling). The coagulation-flocculation processes facilitate the removal of suspended and colloidal particles. It’s used in the first stage of solids-liquids separation: settling, flotation or filtration. In water treatment, coagulation-flocculation involves the addition of polymers that clump the small, destabilized particles together into larger aggregates so that they can be more easily separated from the water. Coagulation is a chemical process that involves neutralization of charge whereas flocculation is a physical process and does not involve neutralization of charge. The coagulation-flocculation...

Sludge Dewatering

Sludge dewatering is the process of removing water from the sludge i.e. generated by DAF or clarification. The sludge produced from a DAF or clarifier will often still contain a large amount of water, this means that significant amount of storage area your sludge holding tank is now full of water that could go to sewer. This water along with the sludge is typically pumped away from the site in tankers at significant cost to your business. GPC’s high molecular weight flocculants in conjunction with a screw press can greatly increase the efficiency of the treatment process, often eliminating the need for tankers saving your business thousands of pounds a year as well as reducing your carbon footprint!* The use of an organic primary coagulant in conjunction with a flocculent can greatly enhance the results given on a belt press or plate and frame press. Sludge dewatering is effective for recycling water and the process will also reduce disposal costs. Key Benefits Reducing your carbon footprint. You can reduce your carbon footprint with sludge dewatering. Transport accounts...

Smell Eggs At Work? Could be H2S. H2S Removal Experts GPC.

H2S Removal – Problem and Solutions Hydrogen Sulphide also is known as H2S and is a colourless gas that produces a foul-smelling odour similar to rotten eggs, It is extremely poisonous, corrosive and flammable. Hydrogen Sulphide results from the microbial breakdown of organic matter this can include human and animal waste, sludge storage tanks, sewers and associated pipelines. H2S is heavier than air and can often fill a building from the ground up. The mixture of H2S air is explosive and burns with a blue flame. Consequences of Corrosion Hydrogen Sulphide forms acidic gases that are very corrosive to most metals. Copper is particularly susceptible to attack resulting in damage to costly electronics and electrical components. Hydrogen Sulphide, when combined with water vapour, leads to the creation of Sulphuric Acid that attacks concrete in sewer lines causing severe degradation that can lead to sewer collapse and rapid system failure. Symptoms of H2S Poisoning H2S irritates the mucous membranes of the body of the respiratory tract, following short term exposure to low PPM...
