Water Filtration

Filtration Solutions for Industrial and Commercial Water Treatment

Effective water treatment often begins with a robust filtration process. By targeting suspended solids, dissolved contaminants, and unwanted organics, filtration ensures water quality remains at the highest standard for various applications. Below, we explore different filtration technologies—ranging from particulate filters (media, bag, cartridge) to advanced reverse osmosis, carbon filters, and cyclone systems—to help you choose the most appropriate solution for your industrial or commercial needs.

Particulate Filtration

Mechanics: Water passes through layers of granular media (e.g., sand, anthracite, AFM) that trap particulates within their pores or on the surface.
Capabilities: Ideal for moderate to high turbidity water; widely used in cooling tower filtration and process water filter systems.
Advantages: Effective filtration down to 1 micron, easy to maintain, no consumable elements and suitable for a range of flow rates.

Organics and inorganics filtration

Activated Carbon Filtration

Activated carbon filters (often referred to as industrial carbon filter when used at scale) are highly porous, allowing them to adsorb various contaminants:

Mechanics: Contaminants bond to the surface of carbon granules or carbon blocks, effectively removing chlorine, organic compounds, and undesirable taste or odours.
Capabilities: Key for reducing oxidants (e.g., chlorine), improving water taste, and removing some organic chemicals.
Advantages: Versatile for both potable and industrial use; often deployed before reverse osmosis or other polishing stages to protect and extend membrane life.

Nitrate Removal and Deionisation

Certain processes demand the reduction or removal of specific dissolved ions:

Ion Exchange Resin

Mechanics: Water passes through resin beads charged with ions that swap places with target contaminants. This facilitates nitrate removal or broader deionisation when targeting multiple ion species.
Capabilities: Critical in industrial processes sensitive to high nitrate levels, or where ultra-pure water is needed (e.g., boiler feed, certain process water filter applications).
Advantages: Offers fine-tuned contaminant removal; resin regeneration extends system life and reduces operational costs.

Iron and Manganese Filtration

Naturally occurring metals like iron (Fe) and manganese (Mn) can compromise water quality and damage equipment without proper filtration:

Fe and Mn Filters

Mechanics: Water is treated using specialist iron and manganese filters that promote oxidation and physical removal. These systems often rely on media beds or catalytic surfaces to convert soluble Fe II to Fe III, allowing insoluble particulates to be trapped and flushed away.
Capabilities: Iron and manganese filtration is essential for groundwater supplies, borehole water treatment, and industrial processes where metal staining, taste, or fouling is a concern. Applications include food and beverage production, building services, and pre-treatment ahead of RO or UV systems.
Advantages: A well-specified Fe filter or Mn filter protects downstream equipment and ensures compliance with water quality standards. Media-based systems offer high capacity, automatic backwash, and low operating costs. Integrated oxidation and filtration units reduce the need for chemical dosing.

Reverse Osmosis for Dissolved Salts Removal

Reverse Osmosis (RO) is a high-efficiency membrane-based technology ideal for tackling dissolved salts, minerals, and other impurities:

Mechanics: Under pressure, water is forced through a semi-permeable membrane, allowing clean water to pass while rejecting dissolved solids and contaminants.

Capabilities: Particularly effective for dissolved salts removal, making it a cornerstone in industrial water filter systems that require low TDS (total dissolved solids).

Advantages: Delivers high-quality, low-conductivity water suitable for boilers, cooling towers, and sensitive process operations.

Deionisation for Ultra-Pure Water

Purpose: Removes ionic contaminants for industries requiring water free from minerals and charged particles.

Benefits: Ideal for applications such as electronics manufacturing and some industrial boiler feed systems where high purity is essential.

Industrial Water Filter

Purpose: Addresses higher flow rates and a broader range of contaminants (both particulate and dissolved) in industrial operations.

Benefits: Tailored solutions (e.g., industrial carbon filter, iron manganese filter, cyclone filters, or multi-media) to meet specific throughput and water quality targets.

Process Water Filter

Purpose: Ensures consistent water quality for manufacturing processes, preventing product contamination and equipment fouling.

Benefits: Enhanced product quality, compliance with industry standards, and improved operational reliability.

Cooling Tower Filtration

Purpose: Minimises the accumulation of suspended solids, organic contaminants, and scaling agents in cooling systems.

Benefits: Reduced maintenance costs, improved heat exchange efficiency, and extended equipment lifespan.

Selecting the Right Filtration Solution

When choosing a filtration system, consider:

Target Contaminants: Are you dealing with particulates, organics, nitrates, or dissolved salts?
Flow Rate & Volume: Ensure the solution can handle the required throughput without pressure drops.
Maintenance & Operational Costs: Evaluate consumable parts, cleaning frequency, and downtime.
Regulatory and Quality Standards: Match treatment processes to local and industry-specific regulations.
