Stainless Steel Filter Housing

What Is The Filter Housing？

The filter housing is composed of shell, multiple filter element, backwash mechanism and differential pressure controller.

It is a direct use of filter screen to intercept the impurities in the water, remove suspended solids, particulate matter, reduce turbidity, purify water, reduce the system dirt generation, in order to purify water quality and protect the normal work of other equipment in the system.

Why Use Stainless Steel Filter Housing?

Industrial filter cartridges has many advantage to use it.

Stability

If the inlet pressure change little, cartridge filter housing runs stably, which can make the whole system smoothly. What’s more, our water filtration housing can withstand greater pressure and play a certain protective role in the industrial filtration system.

Housing water filters also work well in hot water. Just replace the filter elements that is resistant to high temperature.

Intercept contamination

Water filtration housing can be applied to the pretreatment of water treatment, and intercept large particles of impurity and floccules to increase the life of a water filtration system.

Simple operation

The installation of water purify system is simple.

When the differential pressure is big, if there is a backwash device, the filter element will be automatically washed, the differential pressure will drop, and then it work normally;

If there is no backwash equipment, a water filtration system can be directly used by replacing the internal filter element.

Low cost

Compared with the price of the whole water treatment systems, industrial water filtration can purify the raw water very well and extend the working time of the whole system. In the long run, there will be a low cost, high yield effect like the security filters for reverse osmosis systems.

What Industries are Suitable for Cartridge Filter Housing?

It is necessary for many industries to install liquid filter housing to purify water quality and protect the normal work of other equipment in the purification systems for water such as power plant, desalination of seawater, home, chemical engineering food and beverage, agriculture.

Application on the power plant

Filtration of condensate water, boiler supply water.

Multi cartridge filter housing is used in power plants after the multi-medium filters before reverse osmosis;

In the boiler supply water system, industrial water filtration also has a large number of applications, if the filtration accuracy is not suitable including higher accuracy or lower accuracy, then the boiler will be easy to scale, resulting in high temperature and it maybe cause tube expansion or explosion.

Application on the desalination of seawater

Due to water shortage and serious water pollution, desalination of seawater projects are increasing. The main way of seawater desalination is the membrane water process.

Water filtration housing can be used to intercept particles above 5um before reverse osmosis, so that the downstream is not easy to block, and the whole water purify system runs more smoothly.

Application on home

Some home projects start to use the home filtered water system to improve the water quality.

One client ordered a filter which filled with three 40-inch high flow filter elements to purify his household water, and now it worked well.

Application on chemical engineering

Catalyst recycling filter impurities polishing process of alkaline and acidic medium liquid pipeline system as well as the solvent emulsion and dispersion of the industrial filter to remove resin gel.

In the fine chemical industry, activated carbon or catalyst removal is a chemical process the high standard requirement of a typical example of application, PULLNER water filtration housing can not only meet the requirements of high efficiency filter, can prolong service life, improve the reliability.

Application on food and beverage

Filtration of various process water, syrup, and other raw materials.

Water purification filters are widely used in the food and beverage industry. From the raw water filtration in the first step, the water source entering the water treatment systems is guaranteed to have no large particles and suspended matter.

At this time, the micron filters’ accuracy is generally 5um, and the water filtration housing filled with multiple high flow filters is used.

Food and beverage main application scopes: Liquid food and beverage filling before removing impurities filtration; Filter impurities such as suspended solids and precipitate in liquid drinks; Beer, jelly and other impurities in addition to clarify;

All kinds of food production engineering water in the removal of impurities filtration; Soybean oil sunflower oil and other cooking oil filtration; discoloration sugar.

What are the Materials for Cartridge Filter Housing?

First of all, we recommend the water filtration materials for 316 stainless steel which can adapt to various working conditions, its corrosion resistance, high temperature resistance and atmospheric corrosion resistance are very excellent.

What’s the advantage of 316 over 304?

In a variety of organic acid, inorganic acid, alkali, salt, and sea water, it have suitable corrosion resistance, in the reducing acid medium ,its corrosion resistance is far better than 304 stainless steel.

And 304 stainless steel can’t effectively prevent sea salt corrosion.

What are the Surface Treatment Methods of The Filter Housing?

The application and development prospect of stainless steel will be more and wider, but the application and development of stainless steel largely determines the development degree of its surface treatment technology.

1. Stainless steel surface mirror brightness treatment method: according to the complexity of stainless steel products and user requirements can be used respectively mechanical polishing chemical polishing electrochemical polishing and other methods to achieve the mirror luster.
2. The surface color whitening treatment method: in the process of the stainless steel, after rolling plate, binding, welding or after artificial surface fire baking heating, black oxide. This hard gray black oxide is mainly NiCr2O4 and Nif EO4 components, previously generally used hydrofluoric acid and nitric acid for strong corrosion method to remove.

However, this method is costly, polluting the environment, harmful to human body, gradually eliminated now. At present, there are two main kinds of oxidation scale treatment methods:

(1) Sand blasting method: mainly using the method of spraying micro-glass beads, remove the black oxide skin on the surface.

(2) Chemical method: the use of a pollution-free pickling passivation paste and normal temperature non-toxic with inorganic additives in the cleaning fluid for immersion. So as to achieve the stainless steel white color processing purpose. After the treatment basically looks like a dull color. This method is more suitable for large and complex products.

When Do I Replace The Filters of Stainless Water Filter Housing?

The first situation: the inline filters water is equipped with a backwash system. When the differential pressure is large (which can be observed by the pressure gauge).The first thing to do is to shut down the system.

When the backwash device is opened, most of the impurities intercepted by micron filters will be washed, then the differential pressure will decrease, and the system can work normally.

If the water flow is still relatively small after repeated washing, the most cost-effective method at this time is to replace all the filter elements. Because the backwash can prolong the life of the filter element, but the un-washable material on the filter element is more and more leading to the need to replace.

If the differential pressure is too large, you still do not replace the filter elements, light it will lead to filter blockage, system cannot work normally; heavy filter impurities will flow to the back of the system, pollution follow-up device, causing greater economic losses.

The second situation: the filtered water system is not equipped with a backwash system. When the differential pressure is large (which can be observed by the pressure gauge). The first thing to do is to shut down the system, please open the filter housing, the old filter elements need to be taken out and the new filter elements should be directly replaced.

How Do I Change The Filters of Cartridge Filter Housing?

There is an indispensable part in the filter, its name is called the filter element. Filter element is a very common parts, although the price is not expensive, but the effect is very great.

There are a number of users do not know how to replace the filter element, here is a few simple steps for you.

1. To replace the filter elements of the filter, first please turn off the equipment and let the equipment be in a stop state.
2. Prepare the appropriate filter element, the so-called appropriateness is that the specification, material, size model and material, etc. are in line. And we also need the withdraw tools, collection buckets, rags and so on.
3. Thoroughly clean the filter housing and remove other things around the devices and leave plenty of room to operate. Users need to wear protective equipment to avoid any trouble during the whole process.

Cut off filters that needs to be replaced from the system and gently open the vent at the top of the device to relieve pressure.

This process needs to pay extra attention to safety, do not let the material and liquid flow out or splash around.

1. The inside of the filter material needs to be cleaned, use tools to open the lid of the filter, and then take out the old filter element, with the plastic bag has been scrapped filter is installed inside the filter is clean, just wait for installing a new filter.
2. Checks the new filter elements is very important, observe if O-ring in place and if there is any damage about its structure.

Then, the remnant are exiled into the reasonable installation according to the outflow method inside the filter element. At this time, the discharge port of the filter needs to be closed, and the vent valve at the top should also be opened. The vent valve can be closed until the liquid flows out from the top of the shell.

The above is the whole methods of replacing the filter element, the user priority replacement will encounter some trouble which is actually very simple, do not understand the user can have a good reference to see. If you don’t understand how to handle it, this is a good reference to see, and PULLNER hope to help you.
