Transportation:
Transport samples to a certified laboratory as quickly as possible. Maintain proper storage conditions during transportation to prevent changes in water quality.
Laboratory Analysis:
Submit samples to a reputable laboratory equipped to perform the required analyses. Common parameters to assess include pH, turbidity, Hardness, total dissolved solids (TDS), dissolved oxygen, fecal coliforms, heavy metals, and various chemical compounds.

Prepare treatment

Usually filter machine come with pretreatment filter and key filter, but if raw water quality bad it will short the filter machine life. If the factory have condition, We suggestion do an pool or a big tank to remove larger particles, debris, and sediment.

Reverse Osmosis

A Reverse Osmosis (RO) system is an effective technology for filtering and purifying borehole water. Borehole water often contains impurities, minerals, and contaminants that can affect its quality for various uses, including drinking. Here is an overview of how an RO system works to filter borehole water:

  1. Pre-Filtration:
    • Sediment Filter: Borehole water may contain suspended particles and sediment. A sediment filter is typically used as the first stage to remove these larger particles and protect the RO membrane.
  2. Carbon Filtration:
    • Activated Carbon Filter: Activated carbon filters help remove chlorine, organic compounds, and other contaminants that affect the taste and odor of the water. This step improves the overall quality of the water before it reaches the RO membrane.
  3. Precision Filtration: Prevent the particles entering the membrane, scratched the surface of the membrane. In the normal operating condition, the filter can maintained for 3 mouth. The filter structure for fast replace.
  4. Reverse Osmosis Membrane:
    • RO Membrane: The heart of the RO system is the semi-permeable membrane. Borehole water is forced through this membrane using pressure. The membrane acts as a barrier, allowing only water molecules to pass through while rejecting dissolved salts, minerals, and contaminants.

UV (Ultraviolet) system

A UV (Ultraviolet) system is a water treatment technology that utilizes ultraviolet light to disinfect water by inactivating microorganisms such as bacteria, viruses, and protozoa. UV water treatment is commonly used to ensure the microbiological safety of drinking water and for various industrial and commercial applications. Here’s an overview of how a UV system works and its key components:

How a UV System Works:

  1. UV Lamp:
    • The core component of a UV system is the UV lamp. This lamp emits ultraviolet light, specifically in the germicidal range (around 254 nanometers), which is effective at disrupting the DNA or RNA of microorganisms.
  2. UV Chamber:
    • The UV lamp is housed in a protective chamber made of quartz or other UV-transmitting material. The chamber ensures that the water flows closely around the lamp, maximizing exposure to the UV light.
  3. Water Flow:
    • The water to be treated passes through the UV chamber in a controlled flow. The design of the system ensures that all water is exposed to the UV light, effectively targeting microorganisms in the water.
  4. UV Exposure:
    • As water flows around the UV lamp, the microorganisms present in the water are exposed to the ultraviolet light. UV light penetrates the cell walls of microorganisms and disrupts their DNA or RNA, preventing them from reproducing.
  5. Microorganism Inactivation:
    • The energy from the UV light damages the genetic material of microorganisms, rendering them unable to reproduce. While the microorganisms are not killed in the traditional sense, they are inactivated, making them incapable of causing infections or diseases.
  6. Discharge:
    • The treated water, now free from active microorganisms, is discharged from the UV chamber. It is important to note that UV treatment does not remove particulate matter, chemicals, or other non-biological contaminants.

OZONE GENERATOR AND MIXING

Ozone generators are devices designed to produce ozone, a reactive gas composed of three oxygen atoms (O3). Ozone is a powerful oxidizing agent and is commonly used for water and air treatment. When it comes to water treatment, ozone can be introduced into the water to disinfect and oxidize contaminants. Here’s an overview of how ozone generators work and considerations for ozone mixing in water treatment:

Ozone Generation:

  1. Corona Discharge Method:
    • One common method for ozone generation is corona discharge. In this process, electrical discharges pass through dry air or oxygen, causing the oxygen molecules (O2) to split into individual oxygen atoms. These individual oxygen atoms then combine with other oxygen molecules to form ozone (O3).
  2. Ultraviolet (UV) Light Method:
    • Another method involves using ultraviolet light to break apart oxygen molecules, creating free oxygen atoms that can combine with other oxygen molecules to form ozone.

Ozone Mixing in Water Treatment:

  1. Contact Time:
    • To effectively treat water with ozone, it is crucial to ensure sufficient contact time between the ozone and the water. This can be achieved through various methods, including injecting ozone directly into the water or using a contact chamber where water is exposed to ozone for a specified period.
  2. Ozone Injection:
    • Ozone can be injected into the water using a diffuser, venturi injector, or other injection systems. The goal is to disperse ozone bubbles throughout the water to enhance contact and maximize the disinfection and oxidation processes.
  3. Mixing Tanks:
    • In some applications, mixing tanks may be employed to facilitate ozone mixing. These tanks allow for controlled and extended contact time between ozone and water.
  4. Bubble Diffusion:
    • Bubble diffusion systems release ozone as fine bubbles into the water. These bubbles rise through the water, creating contact between the ozone and contaminants.
  5. Venturi Injectors:
    • Venturi injectors use the pressure differential created by the flow of water to draw ozone into the water stream. This method is efficient and often used in various water treatment applications.
  6. Ozone Destructors:
    • In cases where residual ozone needs to be removed from the water before distribution, ozone destructors can be employed. These devices convert excess ozone into oxygen, ensuring that only a safe concentration of ozone is released.

Considerations:

  • Ozone Residual:
    • Monitoring and controlling the residual ozone concentration in treated water is crucial. Excess ozone may require removal to prevent adverse effects.
  • Water Quality:
    • The effectiveness of ozone treatment depends on water quality. Pre-treatment processes, such as filtration, may be necessary to remove particulate matter and enhance the efficiency of ozone treatment.
  • Regulatory Compliance:
    • Adherence to regulatory guidelines for ozone concentration and contact time is essential. Different applications may have specific requirements.
  • Safety:
    • Ozone is a powerful oxidizing agent, and safety precautions must be taken to protect operators and ensure safe handling.

Ozone treatment is effective in disinfecting water and oxidizing various contaminants. When designing a water treatment system using ozone, careful consideration of system components, contact time, and safety measures is crucial to achieve optimal results.

Throughout the entire manufacturing process, adherence to regulatory standards and quality control measures is crucial to ensure that the produced pure water is safe, consistent, and of high quality. The specific methods and technologies employed may vary based on the scale of production, the source water characteristics, and the intended application of the pure water.
