An industrial water treatment system is a combination of a large amount of filter cartridges and filter vessels, which can be applied to different industries and applications. If you are in a field that requires sewage treatment, purification, or water filtration, you would consider the cost of the whole industrial water treatment system.

But it is not an easy thing to calculate the cost, because there are too many factors that affect the total cost. To help you figure out each relevant factor, we analyse the industrial water treatment system, and you will know in which part you can save your costs.

What does an industrial water treatment system consist of?

Before we analyse the industrial water treatment system, we should know what we have in a such water treatment system. Generally, water treatment, process purification and separation, and wastewater treatment are the three basic methods of industrial water treatment.

Which of these treatment types you require, as well as the particular circumstances of your process and plant will have a significant impact on the specific equipment employed in your system. The equipment frequently used in a range of industrial water treatment systems is listed below.

  • Clarifiers: for the sedimentation, flocculation, or coagulation-based removal of suspended particles.
  • Lime softeners: Total dissolved solids (TDS) in feed and effluent are reduced using lime softeners.
  • Coalescer and separator filter: For the removal of oils, use oil/water separators and/or dissolved air flotation equipment.
  • Particle Filtration: Using particle filtration to remove suspended solids and bigger particles.
  • Membrane Filtration: Removal of dissolved particles, biological pollutants, and ionic chemicals using membrane filtration.
  • RO/UF: For the purification of water, use reverse osmosis or ultra
  • Filter presses: for dewatering sludge
  • Ion exchange: for the softening and/or selective removal of ionic compounds, including, but not limited to, hardness, alkalinity, chloride, mercury, metals, and organics.

However, what we mentioned above is not what you must have in your water filtration system. It’s more flexible and customizable to decide what you use in your water filtration system.

Because your industry or application would determine the character of the water treatment system. You can based on your requirements and budget choose the factors above.

The most important costs for an industrial water filtration system

Although we list so many relevant factors above, there are mainly 4 key points for the total cost. Here below, we will give you a detailed explanation of them.

  • Flow rates

Cheaper flow rates typically equate to lower capital expenditures when it comes to industrial water treatment systems. Although this rule applies to the majority of systems, some technologies may be more affected by flow rate than others.

In contrast to large capacity ion exchange (IX) systems, cost disparities between big and small microfiltration (MF) units, for example, are relatively scalable and dependent on flow after the base cost of engineering, control panel, and cleaning systems is covered. For instance, a 50% increase in flow can result in a 20% cost increase.

flow rate

The standard units for measuring system flow rate are gallons per minute (GPM) and/or gallons per day (GPD). When planning your budget for a new water treatment system, keep in mind that your investment will probably be more the higher the GPM or GPD capacity.

When getting a price for a new water treatment system, make sure you have an exact measurement of your process needs because flow rates are always taken into account when calculating the system cost.

Water quality

It is obvious that the liquid plays an important role in the cost of the water treatment system. The quality and content of the liquid that you want to treat are closely connected to the service time of filter elements.

In general, the more toxins present, the more steps there are in the water treatment process, and the more money is required upfront. This is especially true for IX systems, where a complex stream can significantly raise the upfront cost by requiring more resin types, chemicals, and IX beds or columns.

The necessity for prefiltration in complex streams can significantly increase prices for some methods, such as reverse osmosis. Investment in the right pretreatment equipment, while not always technically necessary, can assist in significantly saving long-term expenses by safeguarding downstream equipment, enhancing product yields, and lowering waste disposal costs.

Required standard for purification

Understanding the desired objective outcome for an industrial water treatment system is equally crucial. For instance, if you invest in a pharmaceutical water treatment system, you probably want to meet regulatory criteria, which can differ greatly depending on the items you create.

When choosing the appropriate technology to suit your demands without going over budget for water quality that is above your target range, it can be helpful to have a thorough awareness of the contamination thresholds that are acceptable for your production limits.

Materials of your filter vessels


It is known that many industries have extreme and harsh operating conditions for industrial water treatment systems. There might be high temperatures, high pressure, high corrosivity, and chemical solvents. Fortunately, we have plenty of choices for filter housings.

We can choose FRP tanks or PVC filter housings as substitutions for high-end expensive stainless steel filter housing or rubber-lined filter housing. You often have the option to decide between less expensive manual controls and relatively more expensive automated PLC panels.

The rest of the related factors for the cost of industrial water filtration system

Additionally, we have many other causes that have an impact on the total cost. However, they only occupy a small part of the total costs, so we would only list them below.

  • Space for the system
  • Operation and maintenance costs
  • Automation or manual control
  • Installation
  • Shipment
  • Prepackaged or not
  • Waste disposal costs

What benefits or profits we could get from an industrial water treatment system?

We should not only calculate the investment but also pay attention to the profits we get from the water treatment system.

downstream equipment
  • Protection for downstream equipment:

The filtration before the manufacturing machines or downstream pipelines can prevent clogging, fouling, and scaling problems and protect expensive equipment. At the same time, it can reduce downtime and maintenance costs.

  • Recycle and collect the expensive materials:

In many industries, they need to use an expensive catalyst to do the production. That catalyst can be regained from sewage and reused by the manufacturers.

  • Wastewater safely discharged:

When it comes to waste treatment, zero-liquid discharge (ZLD) systems present a unique situation. They incorporate specialist evaporator/crystallizer units, which can represent well over half the overall system cost because they completely remove water from the effluent stream.

Though it costs a lot, it helps manufacturers to obey local rules and regulations for environment protection. Once you violate the Law on Environmental Protection, the punishment would be way more severe than the costs.
