Surprised to hear ?   Read below...

Paavo Airola wrote about the dangers of distilled water in the 1970's when it first became a fad with the health food crowd.

Fasting using distilled water can be dangerous because of the rapid loss of electrolytes (sodium, potassium, chloride) and trace minerals like magnesium, deficiencies of which can cause heart beat irregularities and high blood pressure. Cooking foods in distilled water pulls the minerals out of them and lowers their nutrient value.

Distilled water is an active absorber and when it comes into contact with air, it absorbs carbon dioxide, making it acidic. The more distilled water, a person drinks, the higher the body acidity becomes.

The most toxic commercial beverages that people consume (i.e. cola beverages and other soft drinks) are made from distilled water. Studies have consistently shown that heavy consumers of soft drinks (with or without sugar) spill huge amounts of calcium, magnesium and other trace minerals into the urine.

The more mineral loss, the greater the risk for osteoporosis, osteoarthritis, hypothyroidism, coronary artery disease, high blood pressure and a long list of degenerative diseases generally associated with premature aging. A growing number of health care practitioners and scientists from around the world have been advocating the theory 
Aging and disease is the direct result of the accumulation of acid waste products in the body.

These and other junk foods can cause the body to become more acidic:
• meats
• sugar
• alcohol
• fried foods
• soft drinks
• processed foods
• white flour products
• dairy products

Stress, whether mental or physical, can lead to acid deposits in the body. The longer one drinks distilled water, the more likely the development of mineral deficiencies and an acid state.

The ideal water for the human body should be slightly alkaline and this requires the presence of minerals like
• calcium
• magnesium

Water filtered through reverse osmosis tends to be neutral and is acceptable for regular use provided minerals are supplemented.

Maximising recovery from sea water RO desalination plants

As the power plants are set across coastal locations the need for more reliable and cost effective desalination is pertinent. Traditionally desalination plants have been associated with not more than 30 to 35% efficiency, but higher efficiency in SWRO with recoveries of 40 to 45% is achieved since 1999. 


To obtain 40% permeate with fluctuating TDS content varying from 38,000 Mg/lit. to 46,000 Mg/lit. with a feed water temperature variation of 25 degrees to 35 degrees C,  with stringent treated water quality of less than 450 mg/lit. TDS level at the outlet of SWRO!!!!!!!!!!!!!!!!!!!! 

Can be achieved?

Yes to achieve that consistently, a reliable pretreatment system and a comprehensive operation and controls mandate was required. The robust pretreatment system consisting of a 2*6160 GPM (2*1400 cubic meters/hr) pretreatment plant followed by a two stage filtration using dual media and pressure sand filters ensures fine and consistant pretreated water quality at the inlet of the Membrane system.

The membrane system consists of four streams of SWRO trains, each with its dedicated energy recovery device, to optimize the energy consumption per unit volume of permeate produced. The energy recovery device used is the advanced pressure exchanger system. The permeate water is mainly used as service water for complete power plant facility.

A part of the desalinated water is further treated through a BWRO system to produce 660 GPM (3600 cubic meters/day) of permeate for feeding the downstream mixed beds demineralization plant for boiler feed application. TDS levels at the outlet of the brakish water reverse osmosis system are in the range of 5-7 Mg/lit. This ensures consistent performance of the downstream mixed bed polisher.

Fluoride in drinking water - means lower IQs and more mental retardation

posted Mar 29, 2012, 5:05 PM by Sanjay Ganguly   [ updated Mar 30, 2012, 1:41 AM ]

Fluorides are found in waste water discharges from process in many industries. Significant amount of fluoride come from the industries like semiconductors, photo-voltaic, glass manufacturers, electroplating, steel and aluminium, pesticide and fertilizer. A maximum of around 1 ppm is allowed in ground water. 

Before it was very difficult to treat fluoride but now it is very simple. 

How to remove fluoride from water by simple technique?

Resin, The fluoride selective ion exchange resin is a chelating resin loaded with aluminium ions. The functional group of resin is an amino - methyl phosphonic acid group , or AMPA - group.

Induction Furnace - Water Problems

In today's core less Induction Melting Systems, water is critical to the cooling of power supplies and furnaces.   

But to ensure efficient coreless induction furnace water systems and melt campaigns, you need 
  • quality water
  • regular treatment 
  • proper filtration
Lets understand why?

Although the water system's main function is furnace cooling, but its efficiency can be affected due to poor water quality. 

Poor water quality leads to

Low cooling rate: A reduction in the heat transfer in the water-cooling passages may be caused by scale formation or fouling due to products of corrosion or biological growth.
When this fouling does occur, the temperature difference between the water and the component will increase to maintain the same heat transfer rate. So this reduces the water system's ability to transfer heat and keep the furnace components cool. As the fouling continues to build up, the temperature increases and the component fails. This process is further aggravated by the reduction of water flow caused by the reduction in the cross sectional area.

Electrochemical corrosion of tubing: Electrochemical corrosion is the deterioration of solids by liquid electrolytes. In this case, the electrolyte is the contaminated cooling water, which attacks metal components in the system. Under severe corrosive conditions, the components can corrode or rust in less than 1 year.

Degradation of electrical performance of the melting equipment: This is due to the water having too high an electrical conductivity. If the water has excessive amounts of dissolved solids in it, it would result into distorted electrical control signals to the furnace's solid state devices. In addition, the ground circuit detector circuits will be

What's the solution?

Use industrial water solutions like Softners, DM Plants etc.
