Water Softening Plant

Water Softening systems are used to reduce the hardness from water and avoid hardness related problems due to water use.

Water Hardness

The hardness of a water supply is determined by the content of calcium and magnesium compounds, which exists to some degree in all natural waters. The hardness in well water is usually higher than that of surface water. Calcium and magnesium can combine with bicarbonates, sulfates, chlorides, and nitrates to precipitate as solids mineral salts make water more basic and corrosion aggressive on many materials.

Hard water is responsible for the formation of lime scaling in pipes,, utensils, water heaters, boilers, HVAC systems, etc., causing inefficiency and sometimes permanent damage. Scale acts as an insulation material, thus lowering heat transmission and often causing premature heater failure due to overheating of the metal.

In other household and commercial applications, hardness also increases soap consumption wasting from 50% to 90% of the soap used, depending on the amount of hardness. It also causes the formation of soap curd, which adhere to cloth fibers, hair, glassware and dishes. Soap curd causes poor results in laundering and may hold pathogenic bacteria.

The presence of salts in lime scale deposits is one of the most common cause of corrosion, which cause damages in water pipelines and boilers. Any descriptive or numerical classification of hardness of water is rather arbitrary. A water that is termed hard in some areas may be considered soft in other areas.

The U.S. Geological Survey uses the following classification:

Soft : less than 60 ppm (as calcium carbonate)
Moderately hard : 60-120 ppm
Hard: 120-180 ppm
Very hard : above 180 ppm

Measurement of water hardness by either conductivity or dissolved solids meters must be performed before any softening treatments. During the water softening processes, carbonates are substituted by sodium, which does not alter the total concentration of dissolved solids.

Process Theory

Initially, strong acid cation resin in the sodium (Na + ) from is placed into service. During the sodium cation exchange water softening process, sodium ions are exchanged for undesirable quantities of calcium (Ca + 2), magnesium (Mg + 2), and iron (Fe + 2). Sodium ions already present in the water being softened pass through the process unchanged. Upon exhaustion of the resin (as indicated by unacceptable hardness leakage), a regeneration sequence involving sodium chloride (NaCI) is utilized, The regeneration sequence reverses the above process and converts the strong acid cation resin back to the sodium from for the subsequent water softening cycle.

Capabilities range from 20,000 to 30,000 grains per cubic foot depending upon the total dissolved solids content of the water, the effluent water quality desired and the amount of sodium chloride regenerant used. It should be noted that although the water is softened, the total dissolved solids content remains unchanged. Further, the effluent contains the same amount of anion as the raw water.

Application

The following facilities are example of ideal applications for water softening equipment:

    Apartments/Condominiums
    Car Washes
    Dairies
    Hospitals
    Farms
    Factories
    Laundries
    Motels/Hotels
    Nursing homes
    Office Complexes
    Resorts
    RO Pre-treatment
    Boilers
    HVAC Systems
    Re-circulation Systems
    Schools

All of the above will experience reduced energy consumption and costly plumbing repairs. The installation of Water 2000, Inc's water treatment system Shoef Soft Water Softners will quickly begin paying for itself. Water heaters and boiler will last longer. Costly special chemicals for boilers and steam handling equipment can be greatly reduced. The service ;life of linens, clothing, fixtures and appliances is noticeably extended.

Without exception, every project which employs the distribution heating and use of water should include a survey of the on site water conditions. Water 2000, Inc's professional staff of trained technicians provides and evaluates this survey to make the appropriate recommendation for all types of applications.

PLEASE NOTE THAT AN EFFECTIVE WATER TREATMENT PROGRAM CAN CONVERT ENERGY LOSES TO ENERGY SAVINGS

 Why use Shoef Soft Industrial Water Softener?

Calcium and magnesium are hard scale forming minerals that build up on piping, heat exchangers, water heaters, boilers and any steam related equipment. This buildup results in costly repairs, increased energy consumption, plugged heat exchangers and boiler tubes. The service life of linens, clothing, appliances and fixtures is greatly reduced due to these "hard" minerals.



Avoid Clogged Pipes with Water Softeners

For laundry and dishwashing, the use of a Shoef Soft water softener will significantly reduce the amount of soaps and detergents, resulting in reduced operating expenses.

Applications for Shoef Soft Industrial Water Softeners

The following facilities are examples of ideal applications for Shoef Soft water softening equipment:

    Apartments/Condominiums
    Car Washes
    Boiler Feedwater
    Hospitals
    Laundries

Why treat Condensate?

Condensate systems always leak. Heat exchangers are where most of the

leakage problems start. This is where untreated cooling water can contaminate the process water causing corrosion. Every system must have a method to handle this leakage. When a condensate system is not properly controlled or simply ignored, corrosion takes place. Iron, copper, and other harmful contaminants are washed back into the boiler systems.
    Reduce Energy Waste using Condensate Polishers

This wastes energy because these contaminants reduce heat transfer. A simple solution is to blow down the boiler to improve water quality, but this wastes heat and requires more makeup water.

The cost effective solution is to "polish" your contaminated condensate for reuse. As more condensate is reused, less make up water is required, reducing both chemical consumption and energy requirements.

Let Water 2000, Inc work up the energy savings available by polishing your dirty condensate. The payback is both swift and dramatic.
