Water Softening Plant

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

Why use 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.

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.

Water Softeners –Commercial & Light Industrial (FRP/ Polyglass Tanks- With control valves)

WATEEN design and supply various types of water softeners using common control valves (Aquamatic, Autotrol & Fleck).
Mostly corrosion resistant Polyglass or FRP media tanks are used with these systems. WATEEN's professional staff of experienced engineers provide appropriate solutions for client's specific requirements and applications.

Effects of Hard_Water_Problems
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.

Shoef Soft Industrial Water Softeners and Condensate Polishers
WATEEN is a leading manufacturer of Shoef Soft industrial water softeners, including various standard and customized systems. The range of systems include top mount fiberglass units for commercial and light industrial applications, Shoef-Soft pre-engineered steel tank valve nest systems for large industrial and municipal applications, non-conventional packed bed systems for critical industrial customers and condensate polishers for industrial boiler water. These systems are available for flow rates from ½ gpm to 925 gpm and higher using multiple units.

Economical and efficient, WATEEN Shoef-Soft Water Softening Systems can be equipped to operate manually, semi or fully-automatically. Regardless of the set up, only limited technical expertise is required for operation.

Shoef Soft 's Sodium Cycle Condensate Polishers WATEEN's Condensate Polishers are high quality industrial systems. They are available in a wide range of self-contained packages configured in single, double and triple unit arrangements.

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.  

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.                                            


 Blocked boiler tubes due to hard water use
Let WATEEN work up the energy savings available by polishing your dirty condensate. The payback is both swift and dramatic.

Features of WATEEN's Shoef-Soft Industrial Water Softeners
WATEEN's Shoef-Soft softeners are high quality industrial systems. They are available in a wide range of self-contained packages configured in single, double and triple unit arrangements.

What is Water Hardness The hardness of any supply water is determined by the contents 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. 


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 for hardness in water:

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 and either conductivity or total dissolved solids (by TDS/conductivity meters) is also 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.

Softeners -- 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 processand 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.

All of the above will experience reduced energy consumption and costly plumbing repairs. The installation of WATEEN'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.
