How to choose suitable large-scale skid-mounted pure water equipment?
2024-08-05
Large skid-mounted pure water equipmentis designed for efficient and effective Water Purification, particularly for surface water treatment and industrial water applications. These systems are typically modular and portable, allowing for easy installation, transportation, and maintenance. Here's a detailed introduction to these equipment, focusing on their main components, working principles, and applications.
Main Components
Pretreatment System: the pretreatment in water treatment equipment is a common and necessary equipment for purifying water.The main purpose is to remove suspended solids,heavy metals,colloids,microorganisms,organic matter,active chlorine,etc.in water,reduce various pollutants in water,and ensure back-end water treatment.The normal operation of the equipment and prolong the service life.
Multi-Media Filters: Remove large particles, suspended solids, and some organic matter.
Activated Carbon Filters
Activated carbon has a large specific surface area and strong adsorption.it can remove organic matter, colloidal silicon, residual chlorine, etc. in water. It has a strong adsorption capacity for odor,chroma, and heavy metal ions, and reduces pollution to back-end water treatment equipment.
Softeners: Remove hardness minerals like calcium and magnesium to prevent scaling in downstream equipment.
Precision Filters: Further reduce particles down to 5 microns or less, preparing the water for Reverse Osmosis.
Fluoride removal filter
When the fluorine content in the groundwater is high (the national standard drinking water fluorine content <mg/l), the defluoridation treatment is carried out through activated alumina adsorption and filtration technology. Equipped with defluoridation tank, filter material,regeneration device, etc.,generally use aluminum sulfate solution or sodium hydroxide solution for regeneration.
Iron&manganese filter
Oxidation method is used to oxidize low-valent iron ions and low-valent manganese ions in water into high-valent iron ions and high-valent manganese ions, which are then removed by adsorption and filtration, thereby reducing the content of iron and manganese in water. The filter material is refined quartz sand or manganese sand, which is often used in groundwater.
Quartz sand filter
The filter is equipped with refined filter materials of different sizes and types,arranged from top to bottom, from small to large, which can remove suspended solids, sediment, clay, humus, etc. in the water, so that the turbidity of the effluent can reach the ideal Effect.
Reverse Osmosis (RO) System:
RO Membranes: The core of the purification process, these semi-permeable membranes allow water molecules to pass through while rejecting most dissolved solids, bacteria, viruses, and organic matter.
Pressure Vessels: Contain the RO membranes and maintain the necessary pressure for water to permeate through the membranes.
High-Pressure Pumps: Provide the required pressure to force water through the RO membranes.
Flow Meters, Pressure Gauges, and Conductivity Meters: Monitor and control the system's performance.
Post-Treatment System:
UV Disinfection or Ozone System: Ensures the elimination of any remaining microorganisms.
Polishing Filters: Further improve water clarity and remove any residual particles.
Storage and Distribution:
Pure Water Tanks: Store the purified water for future use.
Distribution System: Pumps and piping to distribute the water to various points of use.
Control System:
PLC-based or automated control systems manage the entire process, ensuring optimal performance and easy troubleshooting.
Working Principles
The skid-mounted pure water equipment works by first passing the raw water through the pretreatment system, where it is filtered and conditioned to meet the requirements of the RO system. The pretreated water is then pressurized and forced through the RO membranes, where most impurities are rejected, leaving behind high-quality purified water. The purified water undergoes post-treatment, such as UV disinfection, before being stored in tanks for distribution.
Applications
Surface Water Purification:
Suitable for treating rivers, lakes, and reservoirs, converting them into potable water or process water for industrial use.
Removes suspended solids, bacteria, viruses, and other contaminants, ensuring water safety.
Industrial Water:
Used in various industries requiring high-purity water, such as electronics, pharmaceuticals, food and beverage, power generation, and chemical processing.
Ensures product quality, reduces equipment corrosion, and extends equipment life.
Emergency Water Supply:
Quickly deployable in disaster areas or remote locations where potable water is scarce.
Provides clean, safe drinking water to affected populations.
Advantages
Portability: Skid-mounted design allows for easy transportation and installation.
Efficiency: High rejection rates ensure low waste and high water recovery.
Automation: Automated control systems minimize human intervention and reduce operational errors.
Scalability: Can be customized to meet specific water quality and quantity requirements.
Large skid-mounted pure water equipment is a vital tool for surface water purification and industrial water applications. Its modular design, efficient purification process, and wide range of applications make it an ideal choice for various water treatment needs. When selecting such equipment, it's crucial to consider factors such as water quality, quantity, and intended use, as well as the expertise and support offered by the supplier.
