Borehole Water Filtration System for Commercial & Industrial Use

Many industries are turning to borehole water as a sustainable, cost-effective supply. For commercial and industrial sectors—such as data centres, hospitals, food and beverage (F&B) production, and manufacturing—having a reliable source of water is critical. However, untreated borehole water can contain a range of contaminants that threaten process quality, equipment integrity, and regulatory compliance. A robust borehole water filtration system is essential for purifying borehole water before use.
Understanding Borehole Water Challenges
Common Contaminants in Untreated Borehole Water
High Iron and Manganese
Iron and manganese are frequently present in borehole sources. These metals stain equipment and surfaces, affect taste and odour, and promote the growth of iron bacteria—leading to slime formation and clogged lines. Effective treatment typically requires oxidation to convert dissolved metals into solid particles, followed by filtration using media designed to remove iron and manganese.
Hydrogen Sulphide (H₂S)
H₂S is a corrosive, noxious gas identifiable by its "rotten egg" smell. It forms under anaerobic conditions—where oxygen is absent—typically due to microbial activity breaking down organic matter in groundwater. Even at low concentrations, it can corrode metals, damage infrastructure, pose health risks, and cause foul odours. Borehole water containing hydrogen sulphide, particularly in closed systems or storage tanks, must be carefully assessed. If left untreated, it can lead to significant operational issues and regulatory compliance concerns. Effective H2S treatment is essential to mitigate these risks and ensure safe, reliable water use.
Pathogens and Microbial Contamination
Microorganisms such as E. coli, Legionella, and viruses may be present, especially where surface water intrusion occurs. This can happen when cracks or breaches in well casings allow surface runoff—potentially carrying faecal matter or decaying organic material—into the borehole. Once introduced, these pathogens can proliferate and compromise water safety. These pose health risks and can form biofilms that compromise water systems.
Sediment and Turbidity
Fine particles like sand, silt, and clay reduce equipment efficiency and compromise disinfection. If not removed during pre-treatment, these suspended solids can shield microorganisms from UV radiation and hinder chemical disinfectants from reaching their targets effectively. This leads to reduced disinfection performance, higher chemical demand, and potential biofouling issues downstream. Removing turbidity is a vital pre-treatment step.
Water Hardness
High levels of calcium and magnesium lead to limescale build-up in boilers, chillers, and pipework, decreasing energy efficiency and increasing maintenance.
Nitrates, Nitrites, and Organics
Boreholes near farmland may contain nitrates, nitrites, and organic matter due to fertiliser runoff. Elevated levels of these contaminants can present serious health risks, such as methemoglobinemia ("blue baby syndrome") in infants, and may cause water to exceed regulatory limits for potable or process use, particularly in food and beverage applications. These require targeted removal strategies to meet safety and compliance standards—particularly in applications such as food and beverage production.
Borehole Water Filtration & Purification Solutions
Borehole Water Filtration System. A Multi-Stage Treatment Approach
Aevira delivers complete borehole water purification equipment, tailored to your site’s water chemistry and operational needs. A typical system includes:
Media Filters: AFM or multimedia filters remove larger particles. Suitable for high flow.
Bag and Cartridge Filters: High-efficiency filters (1–5 micron or sub-micron), used as polishers or as primary filtration in smaller systems.
Iron and Manganese Removal
Oxidation: Converts dissolved iron and manganese into solids using chlorine, chlorine dioxide, hydrogen peroxide, or aeration. pH dosing may optimise precipitation.
Filtration: Specialised iron manganese water filter media remove oxidised particles. Regeneration or backwash cycles maintain efficiency.
Hydrogen Sulphide (H₂S) Removal
Aeration: Encourages the release of H₂S through controlled air contact.
Oxidation: Breaks down H₂S into sulphur or sulphates using chemical oxidants.
Carbon Adsorption: Removes residual odour and organic sulphur. Certain iron/manganese media may also assist with H₂S capture.
Safety & Monitoring: H₂S gas-in-air detection and tank breather modules support safe, compliant operations.
Disinfection
UV Disinfection: UV-C light neutralises microorganisms as part of a multi-barrier approach, targeting chlorine-resistant microbes and reducing the chemical dose needed for residual disinfection. Suitable for food, healthcare, and industrial water safety.
Chlorine or ClO₂ Dosing: Provides residual disinfection when required. Residuals should be monitored and adjusted automatically. Where water is used as a product ingredient, residual disinfectants may affect taste or formulation—neutralisation may be required before use.
Additional Purification Technologies
Reverse Osmosis (RO): Removes salts, minerals, nitrates, nitrites, and organics. Used in high-purity water applications.
Capacitive Deionisation (CapDI): A tuneable, energy-efficient RO alternative—ideal for applications like brewing where mineral control is key.
pH Adjustment: Optimises oxidation and precipitation processes, protecting downstream components.
Carbon Filtration: Removes organics, pesticides, and odours—particularly important near agricultural areas.
Ion Exchange: Targeted nitrate and nitrite removal using selective resins. Can also reduce hardness.
UV AOP: UV Advanced Oxidation Processes combine UV with hydrogen peroxide or ozone to generate •OH - hydroxyl radicals to degrade trace organics, pesticides, and pharmaceuticals—critical for boreholes affected by agricultural or industrial contamination.
Industry Applications and Benefits
Data Centres & HVAC Systems
Treated borehole water used as make-up for cooling systems offers both cost savings and resilience. Our borehole water filtration system mitigates scaling and biofouling risks, and supports Legionella control. For data centres, borehole supply acts as a backup, maintaining uptime during municipal outages.
Food & Beverage Facilities
Borehole water used in production must be free from taste, odour, and microbial contamination. Carbon filters, UV disinfection, and ClO₂ offer a comprehensive treatment strategy. If residual disinfection is used, it may require neutralisation to ensure recipe integrity.
Manufacturing & Process Industries
From boiler feed to cleaning and rinsing, borehole water supports a variety of industrial uses. Systems can be modular and scalable, growing with your operation. Our borehole water filter system offers flexibility for a wide range of applications. It can be configured for general use or tailored to meet highly specific process requirements.
