Industrial Plants

DM Plant is an Ion exchange technology used to remove salts (cations and anions) from water. Soluble chemical compounds, when dissolved in water, become ionized; that is their molecules dissociate into positively and negatively charged components called ions.

DM Water systems produces high quality water free from any kind of minerals. It operates on the principle of ion exchange, degasification and polishing for treating water and removing ions. Demineralization technology is one of the cost effective solutions for treatment of water. These systems are widely used to treat water in the field of steam, power, process, and cooling.

Demineralised water finds wide application in the fields of steam, power, process and cooling. We have a several successful installations in major power plants, steel mills, refineries, petrochemical complexes, etc.

Use of Demineralized Water Plants :

• Pharmaceutical Industries : Demineralized water is used in the production of pharmaceutical goods, where extremely pure water is necessary to prevent contamination and guarantee product consistency.
• Electronic Industry : Circuit boards and other electronic components are cleaned in the electronics sector using demineralized water and this is due to the possibility of electrical shorts and damage to delicate electronic components caused by mineral-rich water.
• Power Generation : Since minerals and other impurities in the water can lead to corrosion and scale buildup on machinery and piping, reducing efficiency and possibly causing damage, that's why demineralized water is used in power plants for cooling purposes and these demineralized water plants can be easily availed through Demineralized Water Plant Manufacturers in India.
• Automotive Industry : Demineralized water is used in automobile manufacturing procedures when high-purity water is necessary to guarantee the durability and performance of the product, such as batteries, etc. So you can go for a Demineralized Water Plant for a variety of reasons.

Advantages Of Having DM Plants :

• DM plants offer you the best quality water than distilled water
• The DM plants are available for small, medium, and large scale purposes
• DM plants use a natural ion-exchange process without using any chemicals
• The DM plants also have space for water storage
• Using DM plants, you can reduce the overall production cost
• Get normal pH in the demineralized water

Working
Feed water is passed through two small polystyrene beds filled with ion exchange resins. The cations present in water get exchanged with hydrogen ions in first bed. And the anions are exchanged with hydroxyl ions, in the second bed.

• The Feed water is pumped in to cationic based this units remove Cationic ions from the water
• Then the water enters through the Strong Base Anions and Anions get removed from the water stream
• Mixed Bed units polishes the water, greatly reducing the conductivity level
• The feed pumps provide regeneration water to the regeneration skids
• Different regeneration skids provide the necessary amount of dilute chemical to the demineralization vessels
• Finally the demineralized water is then passed to the storage tank

Technical specifications :
After the exchange, the quality of water is as follows:

• Cation quality - less than 10 Micro siemens per centimeters
• 7.5 to 8.5 pH
• Used as a polishing unit, the mixed bed has less than 1 micro siemens quality

Effluent Treatment Plant is developed to treat the effluent that is waste water coming from different areas of plant. Water is the main resource used in all types of industries for many processes. But water used in industries in not consumed completely. Furthermore, almost all industries generate waste water from plants which needs proper immediate action. Waste water can pollute environment. So the treatment of waste water i.e untreated effluent is turned into treated effluent with the help of Effluent Treatment Plant (ETP), so times it is also called as Sewage Treatment Plant (STP).

Crest Infratech is a leading waste water management company with capabilities to undertake Waste Water Treatment Services. We have more than 5 years of experience in waste water treatment industry and deploy continuous efforts to bring cost effective technology.

Principle of reverse osmosis system
Reverse Osmosis (RO) is the process, in which water is pressurized through a semi - permeable membrane. As a result of this, as shown in the below depicted schematic diagram, water will pass through the membrane surface while the dissolved and particulate materials are left behind. When the pressure is applied to the concentrated solution, water is forced through the membrane from the concentrated side to the dilute side. This process is known as "Reverse Osmosis."

The Membrane Based Technology
The application of Reverse Osmosis to the solution of problems in water treatment requires an understanding of the basic mechanisms involved in the process, the limitations of reverse osmosis and the pre treatment requirements.

Reverse osmosis utilizes the unique properties of a Imported semi- permeable membrane to allow fluid to pass while restricting the flow of Dissolved Ionic material. With pressure applied to impure water on one side of such membrane materials, pure water will pass through, leaving most of the impurities behind. The rejection of the dissolved ionic material is a function of both Molecular weight and Ionic charge. For example, we can expect a nominal 90 % rejection of Sodium Chloride, which means that the product water passing through the membrane will have a concentration of salt approximately One-tenth that if the feed water. The rejection of calcium carbonate (Hardness) will be nearly 95%. While most metallic salts will be rejected at a rate of 98% to 99%.

Reverse Osmosis (RO) is a process of physical separation of dissolved solids and minerals present in water. This technology uses the principle of osmosis, wherein the mineral concentration of raw water is reduced by applying high pressure through a semi-permeable membrane.

How Sewage Treatment Plant STP Work?
A sewage treatment plant STP cleans wastewater by converting it into cleaner water. The wastewater is filtered through a series of pipes with discs attached. These disks have small holes that allow air to enter the chamber and move the sewage from top to bottom. During the first stage of the process, the sewage passes through an aeration basin.

The oxygen in the wastewater causes the bacteria in the sediments to digest organic matter and produce clean water. Secondary treatment removes the remaining sediment and pollutants and makes it safe for direct discharge to a watercourse or a sewer.

Once the wastewater has passed through the aeration basins, it flows into the final compartments of the STP. The final phase is called the activated sludge process. This process breaks down the solids in the wastewater, which is then discharged back into the environment. This process is called a multi-stage system, as it treats the wastewater from many properties simultaneously. Once the sewage is treated, it will be released into the environment.
