Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal of this process is to produce water fit for a specific purpose. Most water is disinfected for human consumption (drinking water) but water purification may also be designed for a variety of other purposes, including meeting the requirements of medical, pharmacological, chemical and industrial applications. In general the methods used include physical processes such as filtration, sedimentation, and distillation, biological processes such as slow sand filters or biologically active carbon, chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.
The purification process of water may reduce the concentration of particulate matter including suspended particles, parasites, bacteria, algae, viruses, fungi; and a range of dissolved and particulate material derived from the surfaces that water may have made contact with after falling as rain.
The standards for drinking water quality are typically set by governments or by international standards. These standards will typically set minimum and maximum concentrations of contaminants for the use that is to be made of the water.

“The pollution load on major water bodies has increased over the years due to industrialization and urbanization. Use of water for irrigation, drinking, power and other purposes compound the challenge.”
TO OVER COME THIS CRISIS…
In most developing economies today, the very factors responsible for economic growth, have also unfortunately, been the root cause of environmental degradation. Mass scale industrialization, the intensification of agriculture, rapid population growth, urbanization and rising energy use has taken a grave tool on our ecosystems. There is, therefore a dire need for effective environmental management. Foremost among the many technologies and strategies that have been developed to address this crisis, is Bioculture.
Benefits of “Bioculture”:
This is the most powerful tool to carry out effective Environmental Management and has become the natural choice for carrying out waste treatment.

Antiscalants RO Chemicals:
Without RO chemicals, even the highest quality membranes begin to foul after prolonged use, requiring cleaning or replacement. This process is not only time consuming, but can be extremely expensive. antiscalant is used to process very poor quality feed water at very high rates of recovery, which lessens the load on your membranes, making them last longer. When used properly, antiscalant chemical extends the time between membrane cleanings from a few weeks to years in some cases. Antiscalant and other RO chemicals dramatically increase the lifespan of your membranes, making them last longer and saving you money. In some circumstances, antiscalant can maintain a single set of membranes indefinitely. Without antiscalant, membrane systems would not be successful in serving the water treatment industry.
When it comes to troubleshooting reverse osmosis membranes, identifying issues that cause increases in pressure or decreases in product quality can be very difficult. The great thing about antiscalant is that it solves a number of problems simultaneously, saving you headache and preserving your reverse osmosis membranes. As a general cleaning and quality enhancing purification product, antiscalant is the go-to problem solver that ensures the quality and productivity you deserve.
Antiscalant is a great product that can be used on almost any water without needing to pay for a water chemistry report. For small systems treating less than 150 gpm feed, we suggest 3-5 ppm doses to begin. antiscalant is also an excellent choice for larger systems with good pilot test results or stable operating history.
The typical dosing range for antiscalant is between 2 to 10 ppm. If dilution is required, antiscalant should be diluted with de-mineralized water or RO permeate. If neither of these water sources is available, softened water may be substituted. The dilution for antiscalant should not exceed 10% by weight.

Contaminated water contains particles of different sizes which can be classified as dissolved (< 0.08 μm), colloidal (0.08 - 1 µm), supracolloidal (> 100 - 100 mm) and settleable (> 100 µm)
The type of treatment selected depends on the size of particles present in the wastewater. In practice, treatment efficiency also depends on particle size.
Solids of the size that are visible to the naked eye can be separated either by settling under the influence of gravity or by flotation, depending on the relative densities of solids and water. They may also be easily separated by filtration. However, very fine particles of a colloidal nature (called colloids, size < 1 µm) which have high stability are significant pollutants. The reason for this stability is that these particles have electrostatic surface charges of the same sign (usually negative). This means that repulsive forces are created between them, preventing their aggregation and subsequent settling. It has therefore proved impossible to separate them by settling or flotation. It is not possible to separate these solids by filtration because they pass through any filter. However, separation by SWE-chemical treatments is possible.SWE-chemical treatment of wastewater focuses primarily on the separation of colloidal particles. This is achieved through the addition of chemicals (called coagulants and flocculants). These change the physical state of the colloids allowing them to remain in an indefinitely stable form and therefore form into particles or flocs with settling properties
SHREYANS WATER ENGINEERS specialize in steam boiler water treatment. SWE is a leading manufacturer and supplier of comprehensive range of boiler water treatment chemicals, dosing systems, and water softeners and offer high quality on-site technical service. When water is converted to steam it expands in volume into many times, thus subsequently steam moves the energy and heat where it is wanted, but without the right boiler feed water treatment, a steam-raising plant will suffer from scale formation and corrosion. Consequently it increases energy costs and can lead to downgrade steam, reduce productivity, shorter plant life. An inadequately treated boiler is a potential bomb and exposure to steam will cause severe burns and scalding and may accelerate more serious complexities at plant and operation.
In order to keep plant operating safely, efficiently and economically, SWE has developed a comprehensive range of products and technical services to protect boiler and the whole steam system including the feed-tank, feed-lines, steam and condensate system.
The persistence of SWE boiler water treatment is to render cost effective inhibition to the boiler and steam system against corrosion and scale formation and help to uphold steam pureness and desired quality.
Boiler scale is caused by the precipitation of insoluble salts of calcium and magnesium at high temperature. As a result, it produces a hard layer on the boiler tubes, which severely reduces the heat transfer, which is critically unwanted, thus it greatly reduces the efficiency of the boiler and instigates the boiler tubes to overheat, so that in an extreme situation they can rupture the tubes & lines with very risky consequences.
Formation of scale deposits is avoided initially by removing as much hardness from the make-up water as possible ( through water softener), and then by dosing SWE boiler water chemicals such as Scale preventive and polymer sludge conditioners viz; SWE range of chemicals. These SWE Boiler treatment chemicals ensure that any hardness Slipped-in boiler feed water is converted into a floating sludge, which can be removed by boiler blow down and so doesn’t form any hard scale on the heat transferring surface.
Similarly, Corrosion in low-pressure boilers can be affected by dissolved oxygen, acidity and excessive alkalinity. SWE Boiler Water treatment therefore should remove the dissolved oxygen and retains the boiler water with the appropriate pH and alkalinity levels. The oxygen content of water reduces with intensifying high temperature. it proves therefore that basically increasing the boiler feed water temperature, and allowing the oxygen plenty of chance to get-away, will suggestively decrease the threat of oxygen corrosion at boiler system. A correctly designed feed water container is consequently the primary protection in protecting the boiler from oxygen corrosion. The feed water tank temperature should be maintained at a minimum of 80°C. This could be attained by recollecting as much as hot condensate is possible and by steam injection at feed water tank. A feed temperature of 85–90°C is accepted, but the plant should evade increasing the temperature too high, since it will support other damage in the metallurgy of feed pump.
Microbial cultures are foundational and basic diagnostic methods used extensively as a research tool in molecular biology. It is often essential to isolate a pure culture of microorganisms. A pure (or axenic) culture is a population of cells or multicellular organisms growing in the absence of other species or types. A pure culture may originate from a single cell or single organism, in which case the cells are genetic clones of one another.
For the purpose of gelling the microbial culture, the medium of agarose gel (agar) is used. Agar is a gelatinous substance derived from seaweed. A cheap substitute for agar is guar gum, which can be used for the isolation and maintenance of thermophiles.
