Objectives for Dosing and Water Quality
Treatment goals and characteristics of wastewater should be defined before anything else, as this will sufficiently address the goal of the dosing machine. Four common goals are coagulation, pH adjustment, disinfection, and nutrients addition, which use specific chemicals, as in the use of PAC, PAM, acids, alkalis, or oxidants. Water quality characteristics such as pH, temperature, suspended solids, and variability of flow are important factors in dosing selection and dosing accuracy. These characteristics combined could lead to unintentional poor quality effluent, excessive chemical costs, and high operational costs. There are many site-data examples that show a clear definition of purpose for dosing leads to 15 to 25 percent reduction in chemical treatment costs and improves operational stability of the treatment.
Flow Rate and Dosing Precision
The flow dosing range is one of the most important parameters for selection when choosing a dosing machine. For treatment scale and chemical dosage, calculate real-time and peak dosing volume requirements. For precise low-flow applications, high-accuracy metering pumps are required. For large-flow applications, robust and high-capacity units are required. Having fluctuation ratios and response speed stability when loads are varible dosing is important for all modern dosing systems. Many systems have stepless adjustment and automatic flow proportional control. A correct flow range avoids precision problems, insufficient performance, and energy waste to deliver consistency and reliable dosing performance.
Flooding risk is a huge factor when it comes to buying drainage equipment, but people often overlook chemical compatibility when making such purchases. Chemical compatibility ensures safety, longevity, and durability when dealing with tough chemicals. 316L Stainless Steel, PVC, and PVDF materials resist corrosion to encapsulate hold fast to chemicals. But even these durable materials will fail with highly viscous or especially clogging chemicals. In these cases, clogging, leaks, and premature failure will only create maintenance and replacement headaches. The industry standard is to ensure compatible materials. At Qingdao EVU, we customize our products to ensure chemical safety and compatibility.
Automation and Control System Compatibility
The efficiency of your automation system is reflected in your operational costs. Qingdao EVUmachine automations include: liquid level control, an alarm when chemical levels get low, and timed dosing. For more advanced systems, we include monitoring (pH and ORP levels), dosing control functions based on chemical flow, and systems that allow dosing control from remote locations. For even more advanced systems, our products are compatible with PLC systems and Android/iOS integration. Precise control of chemical dosing and minimal human intervention is an expense saving used to make your operations more environmentally compliant. Qingdao EVU customers prefer our automated dosing control systems due to operational efficiency and overall consistency.
Installation Space and Maintenance Convenience
Qingdao EVU system is designed to make chemical dosing control affordable and practical. Site-specific conditions like space and access are taken into consideration when designing our systems. For finalized spaces, we are able to design compact integrated systems, and for systems in need of future expansion, we design modular systems. Maintenance closing valves and quick-release parts, diagnostic systems, and overall minimal human intervention design reduces Qingdao EVU system downtime. Maintenance closing valves and quick-release parts, diagnostic systems, and overall minimal human intervention design reduces Qingdao EVU system downtime. Chemical dosing control is an affordable and consputomatic system from Qingdao EVU. In design, we focus on minimizing the time it takes to get your system operational.
Supplier Capability and After Sales Service
Operational continuity over the long term is reliant on manufacturer strength and the quality of after-sales service.
