Water Softening Technology for Industrial and Commercial Usage


Water Softening Plant (Softener) Manufacturer custom made plants allows hard water to filter down through a bed of ion exchange resin. The ion exchange resin attracts the calcium and magnesium ions (hardness) and replaces them with sodium ions. This is a benefit for water systems and plants because it prevents scale build-up.

How does a Water Softener Work?
A Water Softening Plant is usually made up of two tanks: a larger one where rock or pellet salt is added, and a smaller tank that contains the ion exchange resins. A control valve causes the system to recharge or regenerate when the ion exchange resins are saturated with hardness.

The heart of a water softener is a mineral tank. It’s Filled with small polystyrene beads, also known as resin or zeolite. The beads carry a negative charge. Calcium and magnesium in water both carry positive charges. This means that these minerals will cling to the beads as the hard water passes through the mineral tank. Sodium ions also have positive charges, albeit not as strong as the charge on the calcium and magnesium.

When a very strong brine solution is flushed through a tank that has beads already saturated with calcium and magnesium, the sheer volume of the sodium ions is enough to drive the calcium and magnesium ions off the beads. Water softeners have a separate brine tank that uses common salt to create this brine solution. In normal operation, hard water moves into the mineral tank and the calcium and magnesium ions move to the beads, replacing sodium ions. The sodium ions go into the water. Once the beads are saturated with calcium and magnesium, the unit enters a 3-phase regenerating cycle.

First, the backwash phase reverses water flow to flush dirt out of the tank. In the recharge phase, the concentrated sodium-rich salt solution is carried from the brine tank through the mineral tank. The sodium collects on the beads, replacing the calcium and magnesium, which go down the drain. Once this phase is over, the mineral tank is flushed of excess brine and the brine tank is refilled.

WaterSoftening Plant Maintenance Application:
·         Boiler Feed
·         Cooling Tower Make-Up
·         Air Conditioning Plant
·         Textile Processing
·         Beverage Production
·         Hospitals, Hotels, Laundries etc.

STP, ETP, RO, DM (Water & Waste Water Treatment Plant)

Image
India's speed of industrialization and development is at peak. New companies are becoming established every day. Of course in these companies, the best things are made for people but along with these, the waste material is expelled and the contaminated water also flows And the human wants that this waste material also be reused.  For these things there are many treatment plants available in India which purify contaminated water from fractures. Well, companies also have to be aware of the environment and It is also important to take the proper steps for the good of the people.  In India, Kelvin Water Technologies Pvt Ltd are one of the fastest and gradually waste water treatment company . Usually we use RO technology to clean water at home and It is usually used for saline water and kills all bacteria’s and viruses and gives us clean and disease free water. From Industrial area,  unwanted and poisonous substances are also expelled like haza...

Benefit of Wastewater Treatment Plant

Wastewater is the water used by residences/households and commercial/industrial entities that has become excessive polluted for further use. Such combination of different types of wastewater causes the resulting wastewater mix to contain suspended and dissolved organic as well as inorganic substances such as carbohydrates, fats, soaps, synthetic detergents, as well as various natural and synthetic organic chemicals. Why waste water treatment plant? The wastewater treatment plant does not only produce clean reusable water, but also has the potential to produce various other benefits. They treat the water that goes down our drains before discharging it back into the environment. The world has a growing and developing population and as things stand right now, we’re on a downward slope in terms of water conservation. The reuse of treated wastewater has become a viable option to minimizing water scarcity problems. Below are some explained benefits: Reduction of waste ...

Extended Aeration Activated Sludge Process Technology For Sewage Treatment Plant (STP)

Image
As the name suggests, it is a modified form of Activated Sludge Treatment system. Extended aeration is a method of sewage treatment using modified activated sludge procedures. Extended aeration agitates all incoming waste in the sludge from a single clarifies. Extended Aeration plants provide a low cost, odor and nuisance-free Sewage Treatment Plant that produces a high degree of treatment. Extended aeration treatment plants are used worldwide to provide simple and effective wastewater treatment . The combined sludge starts with a higher concentration of inert solids than typical secondary sludge and the longer mixing time required for digestion of primary solids in addition to dissolved organic produced sludge requiring greater mixing energy input per unit of waste oxidized. In  extended aeration  process, the raw sewage moves straight to the aeration tank for treatment. The whole process is aerobic. This simplification implies longer aeration time which ha...
