Turn Groundwater Into a Reliable Industrial Water Source

Boreholes can provide manufacturers with an alternative to mains water and potentially reduce long term water costs.

But groundwater chemistry can create very different treatment challenges from a municipal supply.

A borehole should therefore be considered as a raw water source, not automatically as usable process water.

Start With the Analysis

Important parameters include:

• Iron
• Manganese
• Hardness
• Alkalinity
• Silica
• Chloride
• Sulphate
• Nitrate
• Conductivity
• Turbidity
• pH
• Hydrogen sulphide
• Microbiological quality

Iron & Manganese

Groundwater frequently contains dissolved iron and manganese.

Treatment may involve oxidation followed by catalytic or multimedia filtration.

The correct process depends on concentration, pH, oxidation state and required final quality.

Hardness

Where hardness is high, ion exchange softening can protect downstream:

• RO membranes
• Boilers
• Heat exchangers
• Process equipment

Reverse Osmosis

Where dissolved salts need to be reduced, RO can be incorporated after appropriate pretreatment.

The membrane system is projected against the borehole analysis to determine suitable recovery and scaling risk.

Potable & Process Applications

Depending on regulatory requirements and analysis, borehole treatment can support:

• Industrial process water
• Boiler make-up
• Cooling systems
• Wash water
• Manufacturing utilities
• Potable applications where appropriately designed and controlled

Variable Chemistry

Groundwater conditions can change.

Seasonal testing and suitable instrumentation should therefore form part of the operating strategy where water quality variability is possible.

Complete Borehole Treatment Systems

Hydra-Clear can engineer:

Borehole → Pretreatment → Filtration → Softening → RO → Storage → Distribution

with the actual stages determined by the water.

A borehole is a source. Engineering turns it into a water supply.
