Risk mitigation, compliance, safety, and process uptime: these are common requirements in water management in every industry. The EZ Series Online Analyzers from Hach ® provide a solution for continuously monitoring parameters that are critical to these concerns.
The EZ Series Online Analyzers include new and unique parameters, numerous measurement ranges, and provide data 24/7 – so you can make faster decisions. All instruments come in the same rugged mainframe with a compact footprint and a common user interface on industrial panel PCs, keeping training efforts low.
With continuous monitoring from EZ Series analyzers, you can detect trends and identify potential issues – before they become problems.
The EZ Series suite of analyzers is the complete solution for the water cycle, measuring innovative parameters such as ATP, Toxicity, VFA/TAC, and Trace Metals, along with Organics, Inorganics, and Nutrients. Whether for drinking water, wastewater or industrial applications, you can optimize a wide range of treatment processes with the EZ Series.
EZ Series analyzers offer you the ultimate in flexibility, with a variety of measuring ranges, multi-stream capabilities (up to 8 channels), and multiple parameter options – including total or dissolved metals. Be confident in the accuracy of your analysis, with automatic calibration and validation – or choose to introduce your own sample or standard into the analyzer via the grab-sample port.
With EZ Series technology, you can improve process control, avoid downtime, and ensure compliance with 24/7 data availability. Administrator access and activated/deactivated menu keys provide customizable access levels for data security, and a variety of analog and digital communication outputs support easy integration into your systems.
Reliable monitoring of remote locations or unmanned plants allows staff to focus on other tasks. All EZ Series analyzers share spare parts thus requiring less inventory and a common user interface reduces training efforts. Automatic cleaning between samples eliminates cross-contamination. All of this adds up to improved performance in your plant.
Biological contamination of water represents a major risk to plant, equipment, and human health. Waterborne microorganisms represent a problem in many situations where water purity and hygiene are essential and where process optimization is crucial as well. Water utilities, oil & gas facilities, chemical manufacturers, data centers, bottling plants and power stations, therefore, measure microbial load to help minimize corrosion, and optimize plant performance to alert you to possible bacterial outbreaks.
Traditionally, microbiological load or contamination was measured manually in a lab setting. But now, with the Hach EZ7300 online ATP analyzer, microbiological activity can be measured continuously within the process stream, delivering data that allows operators to intervene as soon as a change in the activity is observed.
The EZ7300 determines total bacterial content by measuring ATP of any type of microorganism present in the water sample. And by quantifying intracellular, extracellular and total ATP in the sample, operators can now differentiate ATP in a living cell vs ATP released from a cell that has been subject to disinfection or lysis.
The EZ7300 series can also be used to measure the effectiveness of the biocides being used in the treatment process, to optimize the dosing regime, and help avoid damage to health, environment, and infrastructure.
Effective monitoring and treatment of hardness and alkalinity are key to maintaining stable water in a variety of processes. Hardness and alkalinity are used along with pH, TDS/conductivity and temperature, in the calculation of the Langelier Saturation Index (LSI) to measure water’s propensity to either corrode metals or deposit a scale in a pipe. With the data from continuously monitoring these parameters, plant operators can adjust a process to ensure compliance, avoid permit violations, maximize efficiency, control costs, and operate at the highest levels of health and safety.
Iron is a naturally occurring mineral in both groundwater and surface water, often viewed as water quality indicator during and after the treatment process. In some process applications, iron can also act as a control. So accurate, continuous monitoring of this trace metal is crucial to maintaining quality of both plant processes and output. Whatever the source, concentrations of iron that exceed acceptable levels must be identified and removed
The measurement of iron by colorimetry is represented by the Hach EZ1000 and EZ2000 series models in a variety of measurement ranges. The EZ Series analyzers are capable of measuring total or dissolved concentrations, and have optional multi-stream capability, as well a grab sample port for introducing grab sample into the instrument.
EZ Series online analyzers can monitor various points within the deferrization process and can be used to monitor and confirm initial lab results in iron concentrations before the actual treatment process. After the removal process, measurements can confirm that any remaining traces of the parameters exist in concentrations that meet permit requirements.
EZ series offers automatic and trouble-free measurement of iron at several stages of the process, offering an elegant solution to iron measurement and treatment.
Fluoride is found naturally in soil, water, and foods. It is also produced synthetically for use in drinking water, toothpaste, mouthwashes and various chemical products. Naturally occurring fluoride exists in all oceans, surface water, and groundwater sources, at concentrations from 0.1 to 13 mg/L.
Manganese is a trace mineral, naturally occurring in both groundwater and surface water. Too much manganese can affect color and taste in drinking water and bottled water beverage applications and can cause staining in fixtures and laundry. So accurate, continuous monitoring of both total and dissolved manganese is crucial to maintaining quality. Whatever the source, concentrations that exceed acceptable levels must be identified and managed.
EZ Series Online Analyzers from Hach monitor a range of concentrations of both total and dissolved manganese, using colorimetry.
Currently serving in hundreds of industrial and municipal water applications, EZ Series Online Analyzers allow continuous online monitoring and a matching correlation with standard/laboratory wet-chemical methods, at a high level of precision and accuracy.
This allows you to monitor various points within your process and confirm initial lab results before the actual treatment process. After the removal process, measurements can confirm that any remaining traces of manganese exist in concentrations that meet permit requirements.
Toxicity refers to the admixture of conventional pollutants as well as toxic chemicals such as heavy metals, organic compounds, oxidants, etc. that can be found in waste streams destined for treatment. The source of these toxic compounds can be from a variety of conventional or industrial effluent discharges and can vary in concentration and toxic effects produced.
The EZ7900 Toxicity Analyzer uses a comparison between respiration rate of a healthy sludge sample vs a toxic spiked sludge sample to calculate an index that determines the level of inhibition caused by the potentially toxic influent.
Excess nutrients (nitrogen and phosphorus) in the environment can lead to harmful algae blooms, eutrophication, and an overall decline in water quality. While most online monitoring solutions focus on specific subsets of these nutrients (i.e. ammonia, nitrate, ortho-phosphate, etc.,) the regulatory requirements can be written around the total forms (TN/TP). Thus, automatic, continuous monitoring of TN and TP in the process stream provides time-saving capabilities, can correlate process values to lab results, and can alert plant operators to issues without waiting for lab results. In an era of increasingly stringent effluent guidelines, monitoring your treatment process at critical points can point out process adjustments that are necessary to maintain compliance.
The EZ7600 from Hach, combines two methods for the simultaneous, automatic measurement of TN and TP. With a wide measurement range, and optional multiple-stream analysis, this innovative instrument is a convenient solution for your TN/TP monitoring needs. For customers who don’t need a multiple-parameter analyzer, the EZ7700 or EZ7800 Analyzers offer singe-parameter measurement for TN and TP, respectively.
Volatile fatty acids (VFA) can be a helpful parameter for monitoring certain processes that could be taking place in a water resource recovery facility. When coupled with alkalinity, VFA can be a key parameter for monitoring anaerobic digester health. An increase in VFA and/or a decrease in sludge alkalinity can create an imbalance and indicate potential anaerobic digester operational issues which, without taking action, can result in digester upsets. While VFA are not desirable in excess in an anaerobic digester, they can be a benefit to facilities that perform enhanced biological phosphorus removal (EBPR). VFA are an important carbon source for the bacteriological population responsible for effective biological phosphorus removal.
Hach has a complete portfolio of instruments and chemistries with support and services to help you get the right results.
