Process Water Treatment

It is critical to protect utility and process water from rust and corrosion contamination. Common applications are cooling lines, boiler feed lines, reservoirs, and process water lines. These applications require quality filtration of hard particles (iron, silica, sodium, and others) under 5 microns to protect their tight tolerance components from wear and eventual failure. Poor water quality directly results in increased maintenance and downtime.

Equipment
Boiler System

Application
Boiler Water, Drinking Water, Process Water

Challenge
Process water in Kazakhstan is used for citizen’s day-to-day use, including drinking and bathing. Traditional filtration is unable to adequately clean the particulate under 10 microns causing corrosion build up in pipelines and reservoirs. The government’s annual expenditure in operating costs for boiler management is in excess of $100 million USD.

Solution
Test OEI magnetic filter scrubbers in various locations in the cities of Aktau and Uralsk to:

  • Reduce ferrous and non-ferrous contamination.
  • Improve boiler water and chiller water cleanliness.
    Reduce conventional filter replacement.
  • Protect water system components from wear contamination and corrosion.
  • Compare filtration efficiency against competitor magnetic filtration solutions.

Results

The magnetic filters collected significant amounts of contamination that were for testing; analysis results demonstrated a dramatic decrease of iron, magnesium and other harmful elements.

The government of Kazakhstan is planning to install OEI magnetic filters statewide on major water infrastructure including pipelines, buildings, and other locations.

CASE STUDIES

Calendaring Hot Water System

Improve water quality to sustain consistent heating of the calendar roll’s internal chamber to ensure quality rubber for transmission belt production. Corrosion in the hot water pipes was causing inconsistent heat transfer within the calendar roll’s internal chamber. The uneven temperature on the surface was causing poor quality rubber profile and finishing of the manufactured transmission belts.

Improved Water Quality for Boiler Protection

Improve water quality to limit damage to facility systems and reduce process water contaminants. High volumes of iron oxide, resulting from piping corrosion, enter the boiler system and water supply line; the rust contamination continues downstream, degrading process water quality and damaging facility systems.

Kazakhstan Municipal Water Quality Test

Process water in Kazakhstan is used for citizen’s day-to-day use, including drinking and bathing. Traditional filtration is unable to adequately clean the particulate under 10 microns causing corrosion build up in pipelines and reservoirs. The government’s annual expenditure in operating costs for boiler management is in excess of $100 million USD.

Coolant Flush Water Mechanical Seals

The mill pump flush water was not adequately filtered; wear contamination in the system was causing premature failure of mechanical seals.

Meeting Municipal Water Quality Standards

The challenge was to improve the quality of facility process water to meet municipal standards. This facility uses municipal water in the manufacturing of it’s gun powder. String filters were ineffective in removing the contamination caused by corrosion of the facilities’ carbon-steel piping and systems. The rust contamination resulted in the facility process water failing to meet municipal water quality standards.

Hot Rolling Mill Coolant Flush Water

Contamination in the centrifuge system was causing mechanical seal failure. The coolant flush water required a more effective filtration system than the system’s conventional filter to remove contamination down 4 microns and below.

Campground Water Pump Protection

Water wells are commonly rich with iron oxides. The ferrous contamination prematurely wears on water pump impellars, seals, gaskets and other critical components. Western Canada’s largest campground was experiencing pump failures annually, and required a filtration system that would remove contamination down to sub-micron levels to protect their pump’s close tolerance components.

De-mineralized Water Injection System

Improve the reliability of the turbine rotors in a de-mineralized water injection cleaning system by removing wear contamination that was causing corrosion of stainless-steel and cast-iron piping.

OEI magnetic filters are designed for 95+% efficiency: they are optimized for fluid viscosity, flow volume, flow rate, temperature, mobility, and mounting requirements.
