3 Most Popular Types of Water Filters Nozzles today

Nowadays, all Vietnamese families, factories, agencies, schools, etc. tend to use water filtration systems to ensure the body is provided with clean, safe water for human health. use. And one of the indispensable details in water filtration systems is the water filter nozzle (or filter distributor, filter nozzle, strainer). This is a small detail but plays an extremely important role. Without a filter, the water filter columns will lose their filtering effect.

What is a water filter?

Water filter nozzle is a device that prevents filter material and water from separating, helping to keep the filter material in the filter tank from escaping through the clean water exit. It is an indispensable part in the filtration process of the water treatment system. With specially designed structural details, the water filter hood helps the water to discharge quickly, ensuring the necessary speed and flow without letting the filter material leak out. That is why it is widely applied and used in drinking water treatment systems, demineralized water production, swimming pool water treatment and is especially widely used in urban and wastewater treatment systems. industrial.

Structure of a water filter 

The structure of the water filter hood includes a mesh part with appropriate gaps and a part that collects water out. All are made of the most common fabrication materials used for filter elements which are stainless steel and PP/ABS/HDPE; Reasonable structure; solid connection; high pressure durability; gap does not change; Optimal performance should always ensure throughput. It is suitable for the filtration equipment of combined backwash and water softener water filtration systems, pressure type, backflow and ion exchanger.

The filter hood is composed of a filter with slots to retain filter material, water control holes and an exhaust pipe with small holes to control air flow. Filter nozzles can be made of plastic or metal; Can be installed into concrete, sheet metal floors and lateral pipe systems.

• • Depending on the open area of ​​the slots, more or less water flows through. The slits of the filter hood may be partially blocked by the filter material, changing the resistance across the slits. If the water control hole is located in the body of the filter hood and the slots have a larger open area, the water flow through is less affected by the filter material.
  • The slit size of the filter nozzle varies considerably from about 0.2mm to about 10mm. Large slots accommodate flow filters. Slots of 0.2, 0.3 & 0.35mm are often used for direct contact with the filter material without requiring a gravel layer to support the filter nozzle. This direct contact has advantages for combined aeration and water backwashing.
  • The function of the exhaust pipe of a long-tail air filter is to control air distribution. The exhaust pipe is usually provided with a small upper hole (starter hole or exhaust hole) and lower holes or slots (metering holes/slits). When air is applied to the floor whether suspended or dispersed, the air will collect under the floor and push the water down until the air reaches the metering hole or slit under the filter hood. The measuring hole is sized to prevent air from reaching the end of the pipe tail. If air reaches the end of the pipe, this will cause poor air distribution and localized concentrated aeration causing uneven distribution, it is possible that too strong air bubbles push material into the drainage and mixing channels mix layers of filter material together if using multi-stage filtration.

Application of filter water

Water filter hoods are used in drinking water treatment systems, demineralized water production, municipal and industrial wastewater treatment, river or well water filtration for irrigation…  Water filter filters are available in several models, sizes filter slot size and made of ABS/PP/HDPE plastic with different colors. They match the mechanical, chemical and heat resistance properties to the operating conditions of each plant. Because the cover ensures maximum performance and high durability..
