Filtration In the Process of Water Treatment

Water treatment refers to a wide range of physical and chemical measures taken to make water quality meet certain use standards and specific industry demands, and is widely used in industrial water, irrigation and other fields. Filtration can remove impurities from raw water, protect downstream equipment and improve water quality. Hanke is equipped with a professional technical team to provide you with a wide range of water treatment filtration solutions to meet your production water needs.

4 industrial water pools are built on the ground.

Boiler Feed Water Filtration
Fire Water Filtration
Farm Irrigation Water Filtration

Boiler Feed Water Filtration

Background
Boilers are closed vessels that use a fuel source or electricity to heat water or produce steam for industrial heating and humidification applications, and are widely used in chemical, heating, food & beverage, oil & gas, pharmaceutical, pulp & paper, etc. The water supplied to boilers and converted into steam is called boiler feed water. Most of boiler feed water comes from natural sources such as rivers, reservoirs, lakes and groundwater.
Problem
Untreated boiler feed water generally contains suspended matters such as mud, silt and bacteria. When steam is produced, the solid becomes concentrated and forms deposit at the bottom of the boiler, which leads to poor heat transfer and reduces the efficiency of the boiler.
Solution
As a result, boiler feed water needs to be filtered before use. Automatic backwash filters are generally adopted for boiler feed water filtration as it can not only perform automatic continuous online filtration and uninterrupted filtration during backwashing, but also effectively remove impurities from water and protect boilers from corrosion.

An automatic backwash filter is working on a boiler.

Fire Water Filtration

Background
Fire protection system require a large quantity of water and usually pumps water from sources such as water tanks, lakes, rivers or the sea.
Problem
Water from these sources contains various kinds of debris, such as rust, stones and organic matters and other debris that fall from the inside of the pipes. These impurities will cause pipe corrosion and clogging, if sucked into the fire protection system, it will also lead to downstream equipment wear and increased equipment maintenance costs.
Solution
Therefore, filters are a necessary in fire protection systems. Basket strainers are generally adopted for fire water filtration as they are equipped with strainer baskets inside to resist the impact of large size particles, effectively remove impurities from the pipeline and protect downstream equipment.

Fire water pipeline system is equipped with many basket strainers.

Farm Irrigation Water Filtration

Background
Filtration plays a vital role in irrigation. In agricultural irrigation systems, the water required comes from a wide range of sources, either a nearby source or a distant water body. It may come from rivers, springs, lakes, groundwater, wells, snow, etc.
Problem
As irrigation water comes from various sources and contains a lot of organic suspended matters such as algae, clams, shells, snails, bedbugs, worms, sand, silt, etc., if not removed, it will clog drippers, injectors, sprinklers, control valves and fertilizer injectors, resulting in reduced crop production.
Solution
Therefore, filtration equipment is needed to remove these substances from irrigation systems. Scraper self cleaning filters are generally adopted for farm irrigation water filtration. Compared with traditional filters, scraper self cleaning filters can not only effectively remove impurities from irrigation water, but also eliminate the need for manual cleaning and cartridge replacement, and achieve automatically filter online.
