Maximize Efficiency with Turnkey Metering Packages

When it comes to chemical treatment of water and wastewater, precision, efficiency, and reliability are paramount. It’s not uncommon for plant managers to hire engineers to assist in the design of essential chemical metering systems, also known as skid systems.

Before the system is built, there may be the expense of hiring an engineer, or plant engineers may be needed to take on the task. Additional time is needed to source the required components from a variety of vendors. Once all components are in hand, they will need to be assembled by either inhouse staff, or a contractor. Coordination around other site projects and daily responsibilities of plant personnel can be difficult.

Having so many components from different sources can also increase the possibility of failure due to lack of compatibility between parts, or from failure to follow a manufacturers’ specific installation instructions.

All of these issues can be avoided by choosing a preengineered chemical metering skid system (Figure 1) which is predesigned and preassembled for the end user. With a prefabricated skid, utilities and industrial businesses can minimize downtime, reduce costs, and eliminate the challenges associated with piecemeal assembly.

Benefits Of Purchasing Pre-Fabricated Chemical Metering Skid Systems

Pre-assembled Chemical Metering Skid Systems can offer several advantages over on-site built systems:

Simplified purchasing and installation. When a preassembled skid system is purchased the treatment plant avoids having to source each component individually, such as pumps, flow meters, gauges, valves, and piping. Prefabricated and preassembled skid systems simplify installation and facilitate fast startup, which can significantly reduce installation time and keep labor costs in check.

Single-source warranty and service. Purchasing a complete skid system means dealing with just one vendor for service and support. This eliminates the potential for conflict and fingerpointing that can occur when issues arise in systems built with components from multiple suppliers, designed by a thirdparty engineer, and/or assembled by a contractor.

Enhanced reliability and quality control. Components in a preassembled skid are selected for compatibility with the metering pump and the chemical(s) being dosed. The entire system is typically assembled and tested in a controlled factory environment before shipment to the end-user. This helps ensure delivery of a high-quality and reliable system.

Improved process control. Skid systems are designed to meet specific process requirements for flow, pressure, and accuracy. Features like integrated calibration columns allow users to easily determine the exact output of the pump under their operating conditions, simplifying the process and improving dosing accuracy.

Simplified maintenance. Easy access to all components mounted on a single skid facilitates routine maintenance and troubleshooting. The use of unionized fittings, as opposed to threaded fittings common in on-site builds, can minimize the potential for leaks and simplifies component replacement without requiring extensive pipe cutting. Features like pressure gauges provide invaluable feedback for diagnosing system issues.

Cost savings. Pre-assembled chemical metering skids save money in several ways, including avoiding the expense associated with hiring an external engineer to design the system, reducing installation-related downtime, and minimizing potential for errors and rework.

Enhanced safety. Proper design and pre-testing in a controlled environment can mitigate potential hazards associated with fluid handling. Optional features like pressure relief valves and pressure switches can prevent over-pressurization. Containment trays and integrated calibration columns also minimize operator exposure to chemicals.

Mobility. Having everything together on a single skid allows for easy transportation and relocation within a facility if need be. Large skid systems can be relocated to other locations within the facility using a forklift, while more compact units can be moved manually.

Reduced burden on facility personnel. By opting for a preassembled skid, facility personnel are relieved of the time-consuming tasks of designing, sourcing, and assembling a metering system. This allows them to focus on their core responsibilities and improves overall efficiency.

Designed To Meet the Need

Although pre-fabricated chemical metering skid systems come fully assembled, and in several standard sizes and configurations, many are also offered with a range of optional components and features. For example, on standard skid designs, flow indicators can be replaced with flow meters for more accurate measurement, while pulsation dampeners are beneficial when using diaphragm pumps.

Moreover, manufacturers like Blue-White Industries recognize that certain applications require more tailored solutions. This may involve specifying alternative piping materials to ensure chemical compatibility with the substance being dosed, and may include PVC, CPVC, PVDF, or Chem Proline® (PE). Users also have the option of how many metering pumps they want in their system, one, two or three units are most common.

If floor space is at a premium, Blue-White offers a wall-mounted chemical metering skid system (Figure 2) in one or two pump configurations. This design frees up real estate in cramped equipment rooms and can simplify housekeeping.

Blue-White®, will also make specific modifications such as adjusting the direction of components or the placement of inlets to fit existing facility layouts. A manufacturer’s in-house engineering team may work with customers to understand their needs, generate drawings for approval, and provide tailored quotes, offering the level of flexibility of an outside engineer without the expense of hiring an outside consultant.

In conclusion, pre-assembled chemical metering skids are a reliable, cost-effective solution for water and wastewater treatment. By simplifying installation, enhancing safety, and reducing maintenance burdens, these systems help facilities achieve precise chemical dosing with minimal downtime and maximum operational efficiency.
