Nivelco Instruments for Potable Water Production

Nivelco Process Instruments for Potable Water Production.

Nivelco and Aqua Technology Group can provide all your instrumentation needs for production wells, purification, treatment, and distribution system.

PRODUCTION WELLS

The production wells are drilled in ground layers rich in water, the pumps are lowered into the wells to pump the raw water to the central water treatment facilities.

• Measuring tasks:
• Continuous level measurement of the well
• Temperature measurement of the water
• Hydrostatic pressure (water level) of the production well
• Flow of the produced water
• Dry-run protection of the pumps

RECOMMENDED INSTRUMENTS

• Hydrostatic level transmitters that combine level and temperature measurement: the NIVOPRESS N transmitter family.
• Piezoresistive pressure transmitters: NIVOPRESS NZK types
• Water input measurement: ISOMAG electro-magnetic flow meters

WATER TREATMENT PLANT

The raw water pumped from the production wells contains different organic and inorganic materials. These materials have to be removed from the water. Removal is done either by mechanical filters or by adding coagulant materials to the water to help precipitate the contaminating materials. The resulting slurry is separated in settling tanks. The clean water is often passed through sand or other final filtration stages.

RECOMMENDED INSTRUMENTS

• Pressure measurement with  NIPRESS type pressure transmitters
• Level measurement with EchoTREK ultrasonic level transmitters
• pH measurement of the clean water with AnaCONT analytical instruments
• Low/high level switching with NIVOSWITCH or NIVOMAG level switches

WATER DISTRIBUTION SYSTEM

To move water out to the distribution system and to the customers, the pressure in the system has to be increased. This is done by booster pumps, water towers or air charged pressure vessels with compressed-air pumps.

RECOMMENDED INSTRUMENTS

• Pressure control at the compressed-air pumps with  NIPRESS pressure transmitters and UNICONT controllers
• Water level control at the compressed-air pumps with  NIVOCAP level transmitters and UNICONT controllers
• Water level measurement in the reservoir or watertower with  EasyTREK ultrasonic level transmitters from either the top or the bottom of the water tower with NIVOPRESS D type hydrostatic level transmitters
