What is a Pressure Switch?
A pressure switch is nothing but a combination of mechanical and electronic devices activated automatically whenever the pressure feed water reaches a certain threshold during the water treatment process.
A pressure switch contains a bourdon tube, diaphragm, piston, or membrane that moves according to the pressure exerted by the system. These components are connected to more contacts within the switch. With a certain force, a contact may close or open the switch by depends on its configuration. Pressure switches are used in most industries to check the pressure.
Low-Pressure switches are mainly used to protect the pump/system from the dry run. Whenever there is a low-pressure situation that results in loss of feed water. Low inlet pressure converts the unit to produce more wastewater, less purified or product water, and it also protects the system. Generally, a pressure switch needs to place between the water/liquid pipe and pump. It turns off the pump if the water flow reduces from the main/feed supply or if the pressure is too low for the system to function properly.
The high-pressure switch is introduced to cut the pump off when the pressure reaches high. It controls high pressure when system gets trip.
Benefits of Low and High-Pressure Switches:
- High-pressure and Low-pressure switches aim to protect the RO Raw water / Booster Pump, RO membrane, High-Pressure Pump, and other system components from low or high or pressure damage.
- These Pressure Switches can automatically operate in a specified adjustment of low-pressure or high pressure.

I hope this article is very useful to all, especially those who want to know clearly about low pressure and high pressures in water treatment.
Iron removal filter:
The Iron Removal Filters system is advanced equipment used to remove the iron content in the water by using low-pressure drops.
Iron removal filter systems:
Iron removal filter systems play a crucial role in water treatment systems. Iron is one of the elements majorly available in the earth’s crust. So removing iron from water is a very common problem in many countries. It is the earth’s crust, so it is soluble in water too. It is naturally soluble in water in the form of ferrous iron or ferric iron. Another reason for the iron element in water is that industries like mining, iron, and steel industry.
In order to remove iron from water, dissolved iron need to convert into a suspended form. Very effective removal of iron can be done in two processes. They are:
- Aeration process
- Filteration process.
The aeration process is again divided into the online aeration process and the offline aeration process.
Online aeration process:
Borewell water is pumped into the aeration tank. This tank was divided into three equal-sized chambers. The first chamber is designed as perforated sturdy sprinkle pipes where raw water is allowed through it. Then water can be travel into the other two chambers through different vents located at different baffle walls. Thus produced a zigzag motion in water.
When the water reaches the third chamber, it naturally contacts air, so the dissolved iron gets oxidized and converted into suspended iron. If the feed water PH range is acidic, add a measured dose of a suitable oxidizing agent removal process.
The aeration tank surface is not viable in terms of space constraints. The same needs to be constructed under the ground. In the underground aeration tank, aeration is handled by using a blower and diffuser. To remove underneath sludge precipitated by using sludge pump. Aeration tank’s efficiency may differ upon volumes, dimensions, and designs.
Offline aeration process:
The bore water is allowed into the aeration tank, a single chamber by specially designed sprinkles in this offline aeration process. Then the water needs to stagnate for up to 4 to 8 hours in the aeration tank for a very effective aeration process. If the feed water PH range is acidic, add a measured dose of a suitable oxidizing agent removal process.
Aeration water contains all the suspended iron particles and sent into ferrous free iron removal system with very depth filtration technology. Ferrous-free iron removal contains five layers of distinctive filter media that oxidize the dissolved leftover iron and filters the suspended solids, suspended iron, odor taste, bad color by VOID creations. These ferrous-free iron removals are designed according to the exact flow rate formula.
After the successful filtration process, the accumulated iron suspended particles need to be removed from the ferrous free unit by sending the water towards the reverse direction. In the reverse direction, the water with enough pressure will distrub the filter media and remove all the iron particles using the drain port.
After successful completion of the backwash, the agitated media will be allowed to settle by passing the water through filter media.

Iron removal filter systems play a key role to remove iron content and gives us fresh water.
What are iron removal filters?
The Iron Removal Filters are manufactured mainly to remove the excess iron content in the water by using minimum pressure drop.
Working principle of iron removal filters:
Most iron removal filters work on the principle of oxidizing the iron (oxidation). So it can convert from a ferrous or dissolved to a ferric or undissolved state. When the iron is converted to a ferric state completely, it is scuttled on a filter bed.
For very low iron content in the water, the Filter contains Manganese Zeolite. The iron is oxidized to insoluble or undissolved hydrated oxides, removed by the Zeolite bed’s mechanical filtering action.
Different types of iron removal system processes:
Iron is one of the abundant elements available in the earth’s crust. So groundwater contains iron. It does not affect both human beings and the environment, but it changes the color of water, odor smell which may feel uncomfortable while drinking water. So it is important to remove iron from the water. The following are two types to remove iron from water. They are:
- Chemical iron removal systems.
- Biological iron removal system.
Chemical iron removal systems:
Iron is removed from water by creating an environment called oxidizing, but it should be very strong. It can be successfully created by using the aeration process. Add oxidants like chlorine, or else you can raise the PH range of water by using alkaline materials like limestone. Under these conditions, soluble ferrous iron is converted to ferric iron, forming a precipitate of insoluble iron hydroxide (Fe(OH)3) that filtration can remove. For many decades this process is adopted to treat groundwater throughout the world.
Biological iron removal systems:
Biological iron removal systems are among the best alternatives to Chemical iron removal systems for the past ten years. Microbiologists have discovered that certain bacteria have a strong capacity to oxidize and immobilize iron. bacteria play a key role in the whole process as natural inhabitants in the environment.
So microorganisms are necessary to start the process, and they are carried with the groundwater onto the filters. Then iron oxidizers require aeration to stimulate their growth, grows on the surface area of the filter bed like a slimy orange mat. So if it is in this bacterial activity zone, then the iron removal process appears to occur. Biological iron removal systems also conclude to everyone that the biological enchantment process is very efficient compared to the chemical iron removal technology.
Is iron in water causes any effect to human by consuming it?
Not at all. Iron in water does not affect humans and the environment too. It brings the only unpleasantness of an aesthetic and organoleptic nature. Iron also gives rust color to water sometimes. It also gives a metallic taste to water which seems difficult to drink.

Iron removal filter systems are so helpful for removing iron from water.
A water softener is an updated method to remove hard water. In other words, hard water contains more calcium and magnesium, which affects household things and humans. So those effects are removed by the water softener process.
A water softener works to treat hardness in water by removing calcium and magnesium ions through a process known as ion exchange. Calcium and magnesium ions can cause hardness and damage everything in the home, so they are trapped through resin within the system and exchange them with the necessary amount of sodium ions. Finally, you get soft water as a final output.
How to find that you need a water softener?
The following signs make you know that you need a water softener:
- Mineral-like crust built up all around faucets.
- If your white clothes are dingy or any colors fading unusually
- Soap scum build-up in the sink or on any shower walls.
- If all your appliances break down quicker than their exact life span.
- Stiff clothing even after a load of laundry.
- Irritated skin or itching or dry skin and hair loss after you are showering.
The life span of a water softener:
The life span of a water softener always depends on water hardness and your usage. We cannot identify the life span of the water softener because it may differ based on daily usage and depends on resin. If you carefully maintain resin, then the life span time of the water softener is long-lasting.
Before and after water story of a water softener:
Before the water softener process lime softening process is used, the lime softening method uses calcium hydroxide to remove all hardness ions in water by precipitation. Soft water is achieved by adding lime only in the form of ca(oh)2, which reacts with cations to remove the hardness of carbonate, then reacts with anions to replace these non- carbonates due to multivalent cation and calcium. The Lime softening method produces huge volume sludge, consumes more time, and very hard and complicated process.
To make a more flexible water softener method is introduced. It works more effectively than the lime softening process, and it consumes less time than the lime softening process. The water softening process is very easy.
Different ranges of water softening plants:
FRP water softeners are available up to 2000 mm in diameter.
MS water softeners are available up to 3000 mm in diameter.
MS rubber lined water softeners available up to 2000 mm in diameter.

The water softener method is the only effective way to remove hardness from water, and it is the best solution for those who are facing problems with hard water.
A water softener is an advanced process to remove excess calcium, magnesium in the water. In other words, removing hardness from the water or else removing scaling form on the water.
Benefits of a water softener:
The following are the benefits of a water softener:
Does everyone feel surprised that “is that water softener saves money?” yes, it saves a lot of money. Water softener removes all those mineral ions that accumulate in pipes and appliances and thus saves from more costly repair bills. If you use hard ward regularly in the home, you need to repair or replace all your dishwashers, water heaters, machines, laundry, coffee machines, ice makers, etc. Frequently repair or replacement will affect your money. Using this water softener, you do not find all those repairs and replacements so that you can easily save your money.
Not only for appliances, but it also shows effects on clothes if you wash them with hard water which leads to color fade, you need to buy many detergents within a month and buy new clothes within a month, which cost more money per month. Also affects human health by causing skin allergies, hair loss, etc., which cost more hospital bills. So by using water softeners, you will find the solution for all the above problems and saves your money more.
Earth crust contains many minerals, but this calcium, magnesium, and iron are in excess amount. So it changes color, smell, and taste depend on the area’s environment. It feels unpleasant to consume that water to drink or to use for any purpose. With the help of this Water softener process, all those excess minerals are removed and you can happily use that water.
No color fade and softer clothes:
Hard water shows effects on our clothes too. Suppose if we wash our clothes in that hard water that leaves deposits in fabrics. After some days, those minerals can cause the colors to fade to clothes, and also, few minerals can cause dingy whites or stains. So it is better to wash your clothes with soft water. Soft water easily dissolves into clothes, cleans all the clothes effectively, and soft water also dissolves that special detergent effectively. You can also use less detergent and not requires any special fabric softeners at all. Here water softener can save your time, cleans your clothes neatly, save you money too.
Reduces hair loss problem:
Hard water also causes hair loss problems for everyone. A shower with hard water also does not balance the ph level of your hair, which leads to hair loss problems. It also makes your hair feel dry, brittle, and frizzy, and it can even dull your hair colour. So using soft water will reduce all hair related problems.
Reduces skin related problems:
Using hard water daily for bathing makes you feel like skin irritations, causes skin allergies. The minerals in that hard water also remove our skin’s natural oils, which can even dry out the skin and, for someone, it may even cause itching.
Saves your time:
If you’re using hard water, you need to re-wash all your dishes and laundry, and you need to spend more time scrubbing the chalky lime and soap scum of your showers, faucets, and sinks. Using a water softener prevents all the negative effects of hard water, and soft water dissolves easily and penetrates soap, very less insoluble soap scum or curd collects in the bathroom. Saves your time for cleaning and saves your energy too.

In this blog, you will know about automatic water softeners, the benefits of automatic water softeners, how much you need to add resin and salt, and the best manufacturers.
Automatic water softener:
Before introducing an automatic water softener, everyone uses a manual water softener. The manual water softener process consumes lots of time, manpower to check everything, and it is also very difficult to process. To reduce all the above flaws, automatic water softener machines are introduced. Automatic water softeners also work on the same principle automatically without any manpower. In this automatic water softener process, you need to add a salt tablet, and the whole process is done automatically by machine.
Disadvantages of manual water softeners:
The following are the disadvantages of manual water softeners:
Consumes more time.
Takes more manpower
It is difficult to check anything.
A manual process is very difficult to observe.
Maintenance costs are very high compared to automatic water softener machines.
