Wastewater Plant Solves Combined Sewer And Flow Metering Problems

The Easterly Wastewater Treatment Plant recently found ways to solve two knotty problems at essentially the same time. Because of the number of combined sewers in Easterly’s service area, the plant needed to add capacity and overflow storage, and management decided to also address a need that was going to grow in importance in the near future — flow metering.

VIS is a high-performing yet compact multiphase flowmeter, tailored for wet gas applications and able to provide outstanding accuracy also in the most challenging operating regions.

Flygt Seals

Flygt Seals

The reliability of a submersible product will never be better than the reliability of its sealing system. Unlike dry-installed equipment, any fluid leaking through the seals will accumulate in the pump or mixer and cannot be drained during operation. To achieve long service intervals and high reliability, exceptional demands are made on the sealing system for submersibles.

Proper level regulation is critical for operational reliability. Lack of proper regulation can cause improper operation, pump damage or, in the worst case, overflow that results in environmental and economic consequences. With over a decade of experience and countless satisfied users, the natural choice for level regulation is the Flygt ENM-10.

FLOW CONTROL AND MEASUREMENT

 

Flow measurement can be defined as quantification of the movement of water in a given channel. Flow can be measured either by determining the displacement and/or Velocity of the water. Water meters usually control measure and display total usage in cubic meters, on either mechanical or electronic registers. 

Flow can be divided into two main flows which are: Open channel flow and Closed conduit flow. Flow is controlled by use of valves at intervals to either to slow down, allow faster flow or completely shut down the flow. Some water meters usually perform both the function or making readings and controlling flow while others just conduct measuring only. 

Meters for reclaimed water contain special lavender register covers show that the water is non-potable. Velocity-type meters measure the velocity of flow through a meter of a known internal capacity. The speed of the flow can then be converted into volume of flow for usage. Since Multi-jet meters are usually very accurate in small sizes they are normally used for residential and smaller commercial uses. Turbine meters are not as accurate as jet meters and displacement meters at low flow rates. 

A compound meter is used where high flow rates are necessary. Magnetic flow meters are a velocity-type water meter, except that they use electromagnetic properties to determine the water flow velocity. In water treatment plants, measurement and control devices can be installed in the following locations: within interceptors or manholes, the head of the plant, in the force mains that lead to main tanks etc. Automatic Meter Reading has compelled producers to build pulse or encoder registers to provide electronic output for radio transmitters, reading storage devices, and data logging devices.
