What Is The Best Well Water Treatment System

Well water treatment systems are water purification/filtration plants deployed to eliminate or radically reduce the presence of contaminants in groundwater. Globally, well water is primarily used to support agricultural irrigation. How to choose the best well water treatment system? The answer will be given below!

What is a Well Water Treatment System?


 Figure 1 Well water treatment plant.

Well water is typically groundwater and may contain varying concentrations of contaminants such as arsenic, radon, volatile organic compounds, nitrates, and microorganisms. Common well water treatment solutions include reverse osmosis, water softening, UV, and carbon filtration.
A well water treatment system is a water treatment process where proper integration of a well water treatment system into the well water supply ensures that the end product is of high quality. Well water treatment units utilize a unique water treatment process to achieve optimal results. The treated water can be of varying quality depending on the intended application and does not pose a risk to human health or contaminate industrial products.

Types of Well Water Treatment Systems.

The water derived from drilled, dug, or driven wells has varying compositions and concentrations of contaminants. At NEWater, we manufacture well water treatment systems specialized to treat feed water depending on the prevalent pollutants. Our comprehensive options make certain that all the unique demands of our heterogeneous customer base are adequately fulfilled. Underneath, we briefly expound on the different types of high-quality well water treatment plants NEWater offers.

Reverse osmosis water treatment systems.

Reverse osmosis systems treat your well water by applying pressure on it to force it through semi-permeable membranes. As the name suggests, reverse osmosis utilizes pressure to inverse the ordinary osmotic pressure thereby promoting the flow of water from high concentrations to low concentrations.

Our RO well water treatment systems possess varying capacities and have excellent impurity rejection rates. They are available in standard options for domestic, commercial, and industrial applications.

Figure 2 Reverse osmosis system for well water treatment.

Water softener water treatment systems.

Groundwater often exhibits the mineral concentration of the surrounding soil. As such, water extracted from aquifers likely has concentrations of calcium carbonate ranging from 61mg/L. This implies that the water is hard and its use without adequate treatment could result in scaling. Our water softener units utilize the process of ion exchange to extract the hardness ions (magnesium and calcium) from the well water and ultimately substitute them with sodium or potassium ions.

NEWater’s water softeners are ideal for use in households, commercial enterprises, and industries. For an in-depth understanding, visit our water softening equipment page for details.

Carbon filters for well water treatment.

These systems typically rely on filters with pores measuring 1 micron or less to eradicate particles present in well water. Additionally, they utilize activated media filters to enforce adsorption/deionization by extracting organic constituents, cryptosporidium, chlorine, and giardia.

Figure 3 Activated carbon filters.

Ultraviolet light water treatment devices.

UV light devices are deployed as well water treatment solutions to particularly sterilize the water. They are unrivaled in their bacteria removal rate hence their widespread application in the generation of safe drinking water. The ultraviolet rays destroy the genetic core of pathogens thereby minimizing the risk of transmission of water-borne diseases. UV water treatmetn systems have gained immense prominence in the recent past with Europe recording over 2000 large-scale plants.

The Working Principle of Well Water Treatment Systems.

The upsurge in demand for treated water has undoubtedly inspired the invention and modification of water treatment technologies. Presently there are over 20 water treatment mechanisms being utilized to generate different grades of potable water. Well water is however unique in its composition thereby calling for specialized water treatment technologies. Below are the commonly used well water treatment mechanisms.

Reverse osmosis.

Well water treatment by reverse osmosis is founded on the exertion of pressure to provoke the flow of water from highly concentrated streams to lesser concentrated streams (reverse osmosis). The first step of reverse osmosis involves the pretreatment of the well water using chemical dosing and pre-filters. The aim is to shrink the concentration of iron, calcium, and magnesium, which might cause scaling, and reduce the water’s alkalinity to mitigate the corrosion of equipment.

The pre-filters are tasked with eliminating large constituents present in the well water to avert membrane fouling through clogging. Subsequently, the water is passed through the perforated RO membranes under pressure, and contaminants such as dissolved salts, arsenic, microorganisms, chloride, and hardness minerals are ejected.

Two streams of water are generated, highly concentrated wastewater (brine) harboring the ejected pollutants and freshly treated water. Depending on the imminent use of the water, appropriate post-treatment is enforced. For typical drinking water, the magnesium concentration is adjusted to 34 mg/L while the calcium concentration is adjusted to 10mg/L.

Ultraviolet radiation.

Figure 4 Ultraviolet light disinfection.

Well water treatment systems utilize the germicidal capabilities of ultraviolet light to disinfect contaminated well water. UV light eliminates the following pollutants:

●Other protozoans such as cryptosporidium oocysts.

Development in ultraviolet radiation has seen a recent upsurge in the use of ultraviolet light in well water treatment consequently replacing chlorination. UV light water treatment systems are classified into:

Class A UV light water treatment systems: According to the NSF, these systems’ intensity and saturation score should not be lower than 40,000 uwsec/cm2.

Class B UV light water treatment systems: On the contrary, class B systems have a minimum intensity and saturation score of 16,000 uwsec/cm2. They are often deployed to supplement the treatment of well water contaminated by bacteria.

Technically, UV light treats water by inactivating the microorganisms present in well water. Altering the UV light intensity and the duration your well water is exposed to the UV rays influences the quality of your end product. Most manufacturers provide UV light treatment systems with light intensities ranging from 30,000 to 50,000µwatt-sec/cm^2. The recommended exposure duration is at least 16,000 µwatt-sec/cm^2.

Water softening.

Well water could potentially harbor hardness minerals such as calcium and magnesium. To generate softened water that does not scale your pipes or valuable appliances, it is paramount that you subject your well water to an ion exchange process. Ion exchange typically substitutes hardness minerals with desirable ions like sodium. In addition, ion exchange eliminates other unwanted ionic pollutants such as uranium, nitrates, and manganese ions.

The well water is passed through ion exchange resins (made of sulfonated polystyrene) filled with sodium. In the process, the sodium ions harbored by the resin beads are let loose as the calcium and magnesium ions occupy the resin beads. Once the resin beads are over-saturated, regeneration is initiated.

The Composition of Well Water Treatment Systems.

The existing well water treatment plants are chiefly differentiated by their unique components and treatment processes.  Different well water treatment mechanisms necessitate different machinery, designs, and operational conditions. Below we examine the composition of distinct well water treatment equipment and expound on the roles of each component.

Parts of a reverse osmosis system.

A reverse osmosis system is technically a collection of interconnected components playing different roles with the ultimate goal of effectively treating feed water. The key parts of a reverse osmosis unit are:

High-pressure pump.

A high-pressure pump is paramount to initiate the reverse osmosis process. Primarily, they are deployed to inverse the natural osmotic flow (from low concentration to high concentration) consequently facilitating reverse osmosis.

Pretreatment filters.

The pretreatment phase of a reverse osmosis system harbors filters responsible for eradicating larger constituents thereby averting the risk of membrane clogging. Appropriate filters are determined by the well water’s composition of contaminants.


Reverse osmosis is a membrane-based filtration process utilizing perforated membranes for optimum rejection of dissolved solids. The semi-permeable membranes utilized have perforations measuring 0.0001 microns hence the high salt rejection rates (up to 99.7%).

Control interface.

Additionally, reverse osmosis systems have a user control interface where the user operates the system. For durability, easy operation, and generally smooth operation, NEWater utilizes advanced PLCs and solid-state microprocessors as RO systems control interfaces.

Parts of a water softening system.

As earlier mentioned, the primary water softening process for well water treatment is ion exchange. Ion exchange systems are often deployed as water softeners and can also be utilized as pretreatment units for reverse osmosis systems. Underneath are the primary components of a well water treatment ion exchange system.

  • Ion exchange resin.
  • Control interface.
  • Control valves.
  • The distribution system for regeneration agents.
  • Retention elements.

Parts of an Ultraviolet light system.

Principally deployed to disinfect well water, ultraviolet radiation units are made of four primary components.

Figure 6 Ultraviolet light system for well water treatment.

Ultraviolet lamp.

The ultraviolet lamp is probably the most significant part of the ultraviolet light water treatment system. They are responsible for radiating the germicidal wavelength thereby prompting the disinfection of feed water. Commonly utilized UV lamps include:

  • Standard ultraviolet light lamps.
  • Amalgam ultraviolet light lamps.
  • High output ultraviolet light lamps.

Quartz sleeve.

A quartz sleeve is an elongated, glass tube cylindrical in shape that protects the ultraviolet light lamp from flowing water.

Stainless steel chamber.

This is simply the reactor chamber that harbors the UV light lamp, quartz sleeve, and control interface. Reactor chambers are available in different sizes and shapes but play the same role in all UV light water treatment systems.

Control interface.

It is also referred to as the ballast and is primarily responsible for regulating the UV light lamp’s electrical output. Essentially, the ballast determines the UV rays’ intensity, ultimately influencing the system’s disinfection rate.

Characteristics of Premium Well Water Treatment Systems.

In a market saturated with substandard well water treatment systems and repair components, users must be aware of the basic traits that distinguish high-quality products from mediocre ones. Another key determinant of a good well water treatment unit besides the quality is its suitability for a specific project. For instance, a system intended to treat well water with high iron or acidity concentrations necessitates a pretreatment unit. Underneath, we explore key attributes that will aid you to select a good well water treatment system.

Sufficient Capacity.

The ideal capacity is subjective to the user’s scale of application. Well water treatment plants are endowed with distinct capacity ranges to accommodate the diverse scales of applications different users have (small, medium, and large-scale applications).

Industrial well water treatment systems are synonymous with higher capacities due to the high demand for industrial product water. NEWater’s standard RO well water systems are available in capacities ranging from 28,000 GPD to over 2 million GPD. Due to their high capacities, they are further equipped with equally high maximum operating pressure (450psi).

Similarly, smaller capacities are available for commercial and personal applications. With capacities ranging from 600 to 32,000 gallons per day, you have the luxury of selecting the perfect well water treatment system for your house or business.

Figure 7 Industrial well water treatment system.

Power efficiency.

Generally, water treatment systems have perennially been viewed as energy-intensive alternative freshwater sources. Since the inception of water treatment, manufacturers and other stakeholders alike have gradually lessened the power consumption rates of water treatment processes and machinery. In reverse osmosis, this has been achieved by the use of energy recovery devices.

A good well water treatment system should operate optimally while consuming reasonable amounts of power.  Typically, well water treatment is comparatively energy-efficient when equated to seawater desalination with power consumption rates as low as under 1kWh/m3. A good ultraviolet radiation system, on the other hand, consumes approximately 100- 250 kWh/GPM (low-pressure UV) and 460 to 560 kWh/GPM (medium pressure UV).

Impurity removal Percentage.

The essence of treating water is to generate high-quality potable water with little or no c detrimental contaminants. Therein, a good well water treatment system eradicates the targeted pollutants with impressive results. The dominant well water treatment plants, RO, water softener, and ultraviolet light systems are revered for their effectiveness in alienating impurities from well water.

Ultraviolet light systems are immensely proficient at eradicating microorganisms such as bacteria, viruses, giardia, and cryptosporidium (a removal rate of up to 99.9%). Reverse osmosis is also quite effective in eliminating dissolved solids, organic chemicals, and microorganisms from well water with an impurity rejection rate of 95-99.7%. Water softeners remove up to 99.8% of multivalent ions present in well water.


The investment and resulting operational costs of a well water treatment system are vital considerations most users mull over. For users, a good water treatment plant guarantees quick and sufficient returns on investment capital without incurring hefty operational expenses.

Operational costs of a well water system are classified into installation charges, cost of labor, maintenance costs, power usage, and depreciation value. Underneath we use the projected costs of a reverse osmosis system to estimate the cost of treating well water.

For illustration purposes, we are going to use a 10,000 tons/day well water treatment system in a Chinese setting. In this system, the comprehensive cost of chemicals used is 0.05 yuan/ton while the energy usage is roughly 2.25 yuan/ton of water. Upkeep cost, particularly membrane replacement, is approximately 0.2 yuan/ton while the maximum labor expense is roughly 0.1 yuan/ton.

Lastly, the depreciation rate of RO well water treatment systems is projected at 0.12 yuan/ton thereby totaling 4.54 yuan/ton. It is worth noting that the above projections do not take into account the electrical consumption expenses and charges resulting from loan interest.
