underground water treatment

Types of underground water treatment

Underground water treatment is necessary to purify water hidden below the earth’s surface, making it suitable for human consumption. Several treatment methods exist to aid the process and are often combined to form a complete underground water treatment system.

• Filtration: The most common way of treating underground water is by passing it through a treatment plant that uses various forms of filtration. The process removes bacteria, parasites, and viruses from the water to make it safe for drinking. In rural areas, people use biosand filters to treat their underground water. The filters consist of layers of sand and gravel, and as water passes through the layers, the sand traps harmful sand particles.
• Chlorination: Chlorine has been widely used in water treatment for centuries. The chemical disinfects water by killing all the bacteria present to purify it. Once chlorine is added to water, it reacts and begins to work immediately, releasing gas that kills infectious microorganisms. The treatment works effectively, and water may be deemed safe to drink a few hours after chlorination. Once the water has been treated, chlorine may remain in it for some time as an extra security measure.
• UV Treatment: Treatment plants use Ultraviolet light to expose underground water to a specific wavelength of light that eliminates harmful contaminants. UV treatment is eco-friendly and doesn't make use of chemicals. The method also has several advantages over other methods. For one, it's very effective at purging various microorganisms and doesn't leave any byproduct in the treated water. However, a drawback to UV treatment is that, unlike chlorine, UV light doesn't remain in the water as residual protection against possible future contamination.
• Reverse Osmosis: In a reverse osmosis water treatment system, water is forced through a semipermeable membrane, removing any contaminants, minerals, and impurities. An underground water reverse osmosis system comprises a pre-filter, membrane, and post-filter. Power is required to force the water through the membrane, so reverse osmosis systems usually use electric systems and may require regular maintenance and filter changes.

Specification and maintenance of underground water treatment

Specification

• Capacity and Flow:

  It refers to the volume of water that the treatment system can process within a stipulated time frame. The unit commonly used to describe this is liters per second (L/s) or liters per minute (Lpm).

• Design and Technology:

  It refers to the various types of methods and systems an underground water treatment facility employs to purify water. There are multiple available options, such as membrane filtration, reverse osmosis, UV disinfection, etc.

• Energy and Efficiency:

  An underground water treatment system's energy consumption, efficiency, and overall usage are important indicators to consider. They can help the user understand the treatment facility's environmental impact and operating costs. For instance, factors like energy efficiency can influence whether or not an underground water treatment facility is sustainable.

• Automation and Control:

  These are aspects of an underground water treatment system that are easy to operate, manage and control. Such systems offer the users a chance to monitor and regulate critical parameters like the status of equipment, processing data, alarms, etc.

Maintenance

Daily maintenance practices for an underground water treatment system include:

• Check whether the operating parameters of various equipment are normal, pay attention to the change of water quality and the specific reason for the change, and record the relevant data regularly.
• Check the implementation of the work, such as the disinfection of the water treatment system, the cleaning and sterilization of the equipment, etc.
• Pay attention to the operating status of equipment, such as monitoring the motor's ambient temperature, vibration, etc., and promptly deal with abnormal conditions.
• Keep the treatment facilities clean and tidy, avoid littering, and maintain the sanitation of the environment.

Regular underground water treatment system maintenance practices include the following:

• Regularly inspect the facilities and equipment of the treatment system, looking for problems such as leakage, damage, aging, etc., and deal with them right away.
• Regularly maintain and repair key equipment, such as replacing and maintaining the membranes of membrane separation equipment, maintaining the normal operation of the high-pressure pumps of reverse osmosis systems, cleaning and maintaining UV lamps, etc.
• Conduct regular testing on crucial parameters of the underground treatment system, such as water quality testing, equipment performance testing, etc.

In addition, users can also establish a more scientific and standardized maintenance and management system by formulating the maintenance plan and schedule for underground water treatment systems, which will provide better protection for the normal operation of underground water treatment facilities.

Uses of underground water treatment

• Drinking water supply:

  A safe and functional potable water system is necessary if people reside in urban or rural areas. To make sure the groundwater source is safe for human consumption, an underground water treatment plant should be utilized.

• Industry:

  Many industrial applications use enormous amounts of water, and underground water sources frequently meet these needs. Industries like manufacturing, food processing, textiles, and pharmaceuticals treat groundwater to fulfill quality and purity standards for their procedures and products.

• Agriculture irrigation:

  Farms situated in locations where surface water sources are scarce frequently rely on underground water for irrigation and crop production. By removing pollutants that could harm crops, underground water treatment systems assist farmers guarantee that the water they use for irrigation is clean and nutrient-rich.

• Livestock watering:

  Agriculture operations that raise animals depend on underground water sources for their drinking and other needs. Water treatment for underground sources of aquifers or wells guarantees that the water used by livestock is safe and pure, promoting their health and growth.

• Construction:

  Large volumes of water are needed for activities like dust control, concrete mixing, and excavation in the construction industry. Access to treated underground water is crucial for construction projects to operate efficiently and sustainably.

• Municipal wastewater treatment:

  Some urban centers utilize underground water treatment facilities as part of a larger wastewater management system. Advanced treatment methods enable the safe infiltration of treated effluent into underground aquifers, where it can be stored and retrieved for future use as potable water.

How to choose underground water treatments

When purchasing an underground water treatment system, there are several factors to keep in mind to ensure buyers end up with the right quality and system for their needs.

• Source & flow rate analysis

  Conduct a thorough analysis of the buyer's water source by doing an underground water test to determine the specific types of contaminants present. Additionally, assess the flow rate and yield of the well to understand how much treated water will be needed on a constant basis.

• Treatment options

  Consider the different water treatment options available and how they'll fit into the user's preferences or lifestyle. From the traditional filtration and chlorination to more modern options like UV purification, membrane bioreactors, or reverse osmosis systems - each approach comes with its own pros, cons, and cost implications.

• System size & efficiency

  Choose a treatment system whose size can easily be accommodated in the proposed space of an underground water storage unit. Opt for systems with energy-efficient components, such as low-consumption pumps and high-performance membranes, to minimize operating costs and environmental impact.

• Cost analysis

  Consider all of the costs associated with an underground water treatment system before making a purchase decision. This includes initial investment, installation costs, maintenance requirements, and potential replacement expenses.
