Nitrification testing

Respirometry Plus offers two new tests to determine if influents are toxic to nitrifiers. The tests have been developed by the company for use with its Arthur Bench Respirometer and are designed to help maintain nitrification process control. The tests produce results in less than 20 minutes. For process control, the respirometer measures separately, but simultaneously, the amount of oxygen used in nitrogenous oxidation and the amount used in carbonaceous oxidation.

Data retrieval device

Water level data, collected using dedicated Solinst Leveloggers, can now be retrieved without taking a laptop computer into the field. An inexpensive new hand-held device, the Leveloader, downloads up to 190,000 measurements from up to 50 Leveloggers. Back in the office, the data can be transferred to the office computer. The Levelogger is an accurate, miniature unit with a pressure transducer, temperature sensor, 10-year battery and datalogger all factory sealed in a maintenance-free stainless steel housing.

TPH analysis monitoring

FCI Environmental has introduced its CMS-4000 Continuous Monitoring System to monitor stormwater and wastewater for TPH analysis. Using the company's patented Fiber Optic Chemical Sensor (FOCS®) technology, the system provides trend data and control capability through a 4-20 mA output, as well as being compatible with most commercial SCADA systems. Data correlates well with the Freon/IR method without the need for Freon solvents and is available locally and via modem. The system is intrinsically safe and can simultaneously handle up to four separate sample streams, each with its own 4-20 mA output.

Chorine testing

The Idexx EZ DPD™ dispenser is designed for residual chlorine testing. It allows sample collectors to dispense a pre-measured dose of reagent with the press of a button, eliminating messy powder handling and leftover foil pouches. Refill vials screw on quickly. The testers work with a wide range of color cubes, color wheels and colorimeters. Color-coding distinguishes free and total chlorine tests.
