Coagulant charge analyzer

Chemtrac Systems has introduced its laboratory Coagulant Charge Analyzer (CCA 3100), which is capable of determining the optimum coagulant/polymer dose in five minutes or less. An operator can adapt more quickly to sudden quality changes in the raw water than with conventional jar test equipment, because results can be compared with actual plant performance. The analyzer also enables an operator to verify polymer strength, compare “competitive” coagulants or polymers, “Q.C.” incoming shipments of coagulant or polymers, and troubleshoot process problems.

Chlorine measurement

Emerson Process Management has introduced the Rosemount Analytical Model TCL, a complete system for the measurement of total chlorine in water, including seawater. The new model, comprised of a sample conditioning system, an analyzer and a sensor, significantly reduces cost of ownership over previous generation total chlorine systems by employing readily available, low-cost reagents, and reducing the frequency of reagent replacement by as much as eight times.

Sampling system

Global Water’s Water Quality Sampling System includes a lightweight triggered composite water sampler, a water quality process controller, and a data recorder that is Windows compatible. This compact package is portable for field installation and fully customizable. The controller has two separate relays, one triggering the water quality sampler and the other for controlling all types of external devices.

Sampling station

Safe and quick monitoring of water systems is a challenge for every water operator in the United States. The answer for many water quality professionals has been the selection of the Eclipse #88 Sampling Station for their dedicated sampling sites. Dedicated sampling sites have proven to deliver a secure place available 24 hours a day, a reduction in false-positives, and large man-hour savings. The standard station offers an all-brass waterway and cast aluminum enclosure.

Nitrogen, phosphorus tests

LaMotte, manufacturer of water analysis equipment, has introduced tests for Total Nitrogen (0-25 mg/L) and low (0-3.5 mg/L) and high (0-100 mg/L) Total Phosphorus. The tests are performed by reacting tubes in a heater block to a specified temperature for 30 minutes. Reagents (included) are then added to the tubes and the concentrations are read by a colorimeter or spectrophotometer.

Water quality testing

The Ultrameter II™ multi-parameter series of handheld instrumentation, available from Myron L, is designed for testing critical water quality parameters. The instrument uses advanced microprocessor-based circuitry that improves accuracy and simplifies use. Users simply rinse and fill the cell cup, push the desired parameter key and observe and store the reading. Temperature compensation and range selection are both rapid and automatic.

Chorine measurement

Extech Instruments has announced its patent pending direct measurement technique of total chlorine for its ExStik® Total Residual Chlorine meter, model CL200. The meter monitors residual chloramines and total chlorine including free chlorine, hypochlorite and chlorine bound to nitrogenous compounds. The “stick” meter uses a patent pending flat surface electrode for measurements in liquids, semi-solids and solids.

TOC analyzer

GE Analytical Instruments, division of GE Water and Process Technologies, designed the Sievers® 5310 C Laboratory Total Organic Carbon (TOC) Analyzer to simplify TOC monitoring of raw and finished drinking water for USEPA compliance reporting and plant optimization. The analyzer requires minimal operator training and can be set up and analyzing samples in less than one hour. Unlike other TOC analyzers using combustion oxidation or Non-Dispersive Infrared (NDIR) technology, the Sievers system requires no high-purity gases, toxic catalysts, external reagents, or ultrapure gas generators.

pH electrodes

HF resistant pH electrodes from Sensorex increase electrode life for pH measurements in solutions containing acidic fluorides. There is no need to use antimony or other non-classic methods to measure pH in the presence of acidic fluoride. A special formulation flat surface pH glass enables these electrodes to resist etching due to HF attack. They work like conventional pH electrodes so calibration is accomplished with normal standard pH buffers.

Water analysis

Inficon Scentograph on-site water analysis systems are designed for automated, unattended monitoring of volatile organic compounds (VOCs) in water. Scentograph CMS has a direct, automatic purge and trap technique that delivers immediate analysis, unlike conventional systems that require manual sample collection and preparation prior to analysis. It is available as a portable on-site system or as a stationary console providing continuous, on-line monitoring for VOCs in water.
