Primary wastewater treatment systems include different types of physical-chemical treatment equipment depending on the components in the wastewater. Often, industrial wastewater contains toxic or hazardous amounts of chemicals, resulting from the industrial process; some chemicals may be suspended, while others are dissolved in this wastewater. Additionally, physical-chemical treatment removes suspended and dissolved particles contained in wastewater.
We understand that effective primary wastewater treatment is critical to your plant operations, whether you are discharging directly to a POTW or treating prior to your biological wastewater treatment system. Clarion Water Technologies can provide creative solutions to optimize the performance of treatment chemicals and equipment that can dramatically minimize costs, maximize your return on investment, and significantly enhance your bottom line results.
Coagulation & Flocculation for Primary Treatment
Coagulation and flocculation involves the removal of suspended solids and turbidity from water to prepare it for use or for further treatment. This step typically uses the difference in density between the water and the suspended material for separation. The process of coagulation, along with flocculation, is used whenever the natural settling rate of suspended material is too slow to provide effective clarification. Coagulants are used to neutralize the charge of the suspended solids, bringing the particles together to create a small “pin floc”. To generate larger particles or flocs for faster settling, a high molecular weight, organic flocculant is generally used in combination with a coagulant.
Clarion Water Technologies offers a comprehensive suite of organic and inorganic blended coagulants and organic flocculants. We can work with you to optimize the performance of your treatment program, including chemicals and equipment, which can dramatically minimize your overall costs and maximize return on investment.
An oily waste emulsion, in which oil is dispersed in the water phase, may contain any one of several types of oil in a wide range of concentrations. In addition to oils, typical contaminants of these emulsions may solids, silt, metal particles, emulsifiers, cleaners, soaps, solvents, and other residues. the type of oils found in these emulsions will depend on the industry. They may be fats, lubricants, cutting fluids, heavy hydrocarbons such as tars, grease, crude oils, and diesel oils, and also light hydrocarbons such as gasoline, kerosene, and jet fuel. Their concentration in the wastewater may vary from only a few parts per million to as much as 5-10 percent by volume. Treating the emulsion is usually accomplished using coagulants dosed at an appropriate level to neutralize the electrostatic charge.
Waste treatment antifoams are used to eliminate or control foam primarily in secondary treatment and final effluent areas in a waste treatment plant. Industries often in need of waste treatment antifoams include food processing plants, paper mills, refineries, municipalities, and petrochemical plants, among others.
Clarion Water Technologies has a full range of antifoams, including food grade products that can effectively help suit your needs. We will work with you to identify and thoroughly analyze your foaming problems, allowing us to select and effectively apply the proper antifoam for your specific application.
Odor Control for Wastewater
Clarion Water Technologies understands that odor problems are a nuisance to the community and a concern to your waste plant personnel. Wastewater odors range from musty smells to hazardous gases. Most of the odor producing compounds in domestic wastewater result from the anaerobic biological decomposition of organic materials. Industrial waste treatment systems also have specific odor sources and encounter unique problems in dealing with the odors. Understanding the source and nature of wastewater odors is a major step toward controlling problems, and we have many program options that can effectively help meet your needs.
Following primary treatment, wastewater is often sent to what is known as secondary treatment. In secondary treatment, up to 90 percent of the organic matter in the wastewater can be removed by leveraging naturally occurring biological processes. Although many types of plant layouts exist to biologically treat wastewater, they all rely on a healthy, well-acclimated population of microorganisms that require careful management. Various inputs like dissolved oxygen, temperature, and nutrient levels are all critical to the efficiency of the process. A final step, known as secondary clarification, allows wastewater to settle before it is reintroduced into the environ
Sludge dewatering is the removal of water from wastewater treatment solids slurry (sludge) in quantities greater than what is achieved by thickening. Mechanical processes and land dewatering techniques are detailed to aid in selecting the most appropriate method for the sludge under consideration. One major reason for dewatering is to decrease the capital and operating costs for final sludge disposal. Dewatering sludge solids from a 1 to a 20 percent solids concentration reduces volume by three-fourths and generates a cake-like material that has a non-fluid consistency.
Our flocculants are specifically designed to meet your most demanding sludge dewatering needs, whether you are using a centrifuge, screw press or belt filter press. We can also perform detailed system audits and diagnostics to prescribe the best chemical, equipment and service programs to maximize your system performance and efficiency.
Water Use and Recycling
As demands for better water stewardship increase throughout the world, so, too, will the needs for managing this precious resource in industrial operations. This includes a number of activities, including having a better understanding of all the uses of water throughout an industrial complex and conserving water when appropriate; finding innovative ways to treat single or combined wastewater streams; as well as recycling of water to improve water and energy efficiency.
Water Usage & Conservation
Clarion Water Technologies understands all of the uses of water within an industrial complex. From water for utilities to facility management to process applications, Clarion Water Technologies has essential expertise in understanding water and its impacts on your operations. Clarion Water Technologies has proprietary knowledge and tools to increase customers’ awareness of water usage in either an individual facility or across several facilities. Additionally, we document best practices across several regions and industries to benchmark consumption and also to identify key areas for conserving water and energy.
Point Source vs End of Pipe Wastewater Treatment
Wastewater treatment has traditionally been viewed typically as “end of pipe,” or as one combined stream. However, because Clarion Water Technologies takes a holistic approach to integrated water system management, we identify innovative ways to isolate and treat particular waste streams. This could mean implementation of one or more different wastewater treatment methodologies (primary, secondary, and tertiary) in one or more appropriate locations within a facility. The end result is to minimize capital investment, operational cost, and environmental liability.
Water System Reuse and Recycling
As water resources become more and more constrained, so too will the need to identify appropriate methodologies to reuse existing water flows within a facility. To be successful in this endeavor, this requires an advanced knowledge of water quality requirements in various operations, as well as the best in class technologies to provide these prescribed water quality requirements. Clarion Water Technologies utilizes a combination of a practical engineering approach and hands-on knowledge of system operation to design, build, operate and/or maintain the optimal reuse solution for each application and customer.
