Transit time flowmeters

Rittmeyer manufactures and installs multi-path, transit time flowmeters for large pipes and open channel applications with accuracy ratings of 0.05% and 2.0%, respectively. This class of meter is designed for difficult hydraulics that consist of minimal straight runs, elbows, or valves immediately upstream of the metering section. Hot-tap and retrofit capabilities along with spool-piece fabrication are advantages with the company's Risonic2000 flowmeter.

J-Spin solid bowl decanter centrifuges from USFilter Dewatering Systems offer a minimal-maintenance solution to continuous liquid clarifying and solids de-watering. The versatile systems are easy to operate and require little operator attention. They are capable of adapting to varying throughput, process and material types. The J-Spin system consists primarily of a bowl, conveyor, motor/backdrive and base. The case serves as a guard and complete enclosure for the rotating assembly, as well as containing and directing the cake solids and effluent discharged from the rotating assembly. The enclosed design is effective in reducing odor emission while dampening noise levels. The small footprint and minimal exposure to moving parts are beneficial in many applications.

Insertable magmeter

Marsh-McBirney recently introduced an addition to its existing Multi-Mag™ product line - a new high strength probe designed for high velocities and large pipe sizes. The new insertable multi-electrode sensor is ideal for pipe sizes 36 to 120 inches. An array of electromagnetic sensors is located on the insertable probe that spans the entire pipe diameter. The probe detects and compensates for shifting profiles.

Customized pump solutions

Standard Alloys offers its Custom Hydraulic Solution (CHS) to reduce or eliminate cavitation, increase capacity and reduce power consumption. This 46-inch custom impeller design has increased the capacity of the Worthington pump from 88,000 gpm at 96 feet Total Developed Head (TDH) to 94,000 gpm at 100 ft TDH. The CHS decreased the Net Positive Suction Head Required (NPSHR) from 22 feet to 17 feet at the 94,000 gpm flow and reduced the pump cavitation. Additionally the amp loading on the 2500 horsepower motor was reduced from 329 to 319 with the increased capacity. The company also upgraded the metallurgy from bronze to CD-4MCu.

Chlorine dispenser

The IDEXX EZ DPD™ dispenser makes residual chlorine testing easy. 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 easily and quickly. The dispenser works with a wide range of color cubes, color wheels and colorimeters. Color-coding distinguishes free and total chlorine tests.

Membrane bioreactors

Dynatec Systems and NORIT Americas have agreed to jointly develop the U.S. market for Membrane Bio Reactors (MBR). The MBR is a compact waste treatment system that combines biological treatment with membrane separation. The membrane concentrates the biomass, and offers a more compact design and a short residence time.
