Biocolours – Safe food colours

Added on: October 23rd, 2013 by Afsal Meerankutty No Comments

Biocolours-A New Generation Additive For Industries?
Biocolours or natural dyes are derived from plants, insects and minerals. The use of such colouring matter is rooted in antiquity. Relics from the excavations of Harrapan Culture have yielded evidence of ropes and fabrics dyed with natural colours. The caves of Ajanta (the earliest dating back to the first century B.C.) still preserve the beauty of biocolours in their fullest splendour. In short, use of biocolours through the art of dyeing and printing is one of our richest heritages. Biocolours had to pay a very heavy price due to the development of the synthetic genre of dyestuff. Synthetic dyes made their advent in India in the 18th century and gradually pushed natural dyes into oblivion due to their superiority in the speed of dyeing or printing and the fastness of colours.

Bio-Medical Waste Management

Added on: October 11th, 2013 by Afsal Meerankutty No Comments

Medical care is vital for our life and health, but the waste generated from medical activities represents a real problem of living nature and human world. Improper management of waste generated in health care facilities causes a direct health impact on the community, the health care workers and on the environment Every day, relatively large amount of potentially infectious and hazardous waste are generated in the health care hospitals and facilities around the world. Indiscriminate disposal of BMW or hospital waste and exposure to such waste possess serious threat to environment and to human health that requires specific treatment and management prior to its final disposal. The present review article deals with the basic issues as definition, categories, problems relating to biomedical waste and procedure of handling and disposal method of Biomedical Waste Management. It also intends to create awareness amongst the personnel involved in health care unit.

Polymer Fiber Reinforced Concrete Pavements

Added on: March 11th, 2012 by Afsal Meerankutty 1 Comment

Road transportation is undoubtedly the lifeline of the nation and its development is a crucial concern. The traditional bituminous pavements and their needs for continuous maintenance and rehabilitation operations points towards the scope for cement concrete pavements. There are several advantages of cement concrete pavements over bituminous pavements. This paper explains on POLYMER FIBRE REINFORCED CONCRETE PAVEMENTS, which is a recent advancement in the field of reinforced concrete pavement design. PFRC pavements prove to be more efficient than conventional RC pavements, in several aspects, which are explained in this paper. The design procedure and paving operations of PFRC are also discussed in detail. A detailed case study of Polyester fiber waste as fiber reinforcement is included and the results of the study are interpreted. The paper also includes a brief comparison of PFRC pavements with conventional concrete pavement. The merits and demerits of PFRC pavements are also discussed. The applications of PFRC in the various construction projects in kerala are also discussed in brief.

Ozone Water Treatment

Purifying Water With Ozone.

Ozone has been used in Europe for water treatment since early in the 20th century. Initial applications were to disinfect relatively clean spring or well water, but they increasingly evolved to also oxidize contaminants common to surface waters. Since World War II, ozonation has become the primary method to assure clean water in Switzerland, West Germany and France. More recently, major fresh water and waste water treatment facilities using ozone water treatment methods have been constructed throughout the world.

Relatively, the use of ozone for water treatment and purification in the United States has been much more limited. However, the use of ozone has been increasing here in the US, particularly over the last decade as the negative effects of chlorination have become more apparent. For example, a modern water treatment plant in the USA has been built by the City of Los Angeles to use ozone for primary disinfection and microflocculation of as much as 600 million gallons of water per day. An East Texas power utility will be the first small water utility service in Texas to use ozone water treatment technology for drinking water purification. They have hired BiOzone for this task.

In the field of creative ozone water treatment, BiOzone designs, manufactures, and installs the finest ozone generator systems produced today. Each component interfaces harmoniously with the others to achieve the most cost effective and optimum performance. These process trains are installed around the world in a variety of industries. The solutions we offer are nowhere else available in the world.

Common Synthetic Plastics

Added on: February 28th, 2012 by Afsal Meerankutty No Comments

Plastic molecules are made of long chains of repeating units called monomers. The atoms that make up a plastic’s monomers and the arrangement of the monomers within the molecule both determine many of the plastic’s properties. Plastics are one of the classification of polymers .If a polymer is shaped into hard and tough utility articles by the application of heat and pressure ,it is used as “plastic”.

Synthetic polymers are often referred to as “plastics”, such as the well-known polyethylene and nylon. However, most of them can be classified in at least three main categories: thermoplastics, thermosets and elastomers.

Man-made polymers are used in a bewildering array of applications: food packaging, films, fibers, tubing, pipes, etc. The personal care industry also uses polymers to aid in texture of products, binding etc.

Artificial Turf

Added on: February 13th, 2012 by Afsal Meerankutty No Comments

Artificial turf is a surface manufactured from synthetic fibres made to look like natural grass. It is most often used in arenas for sports that were originally or are normally played on grass. The main reason is maintenance — artificial turf resists heavy use, such as in sports, better, and requires no irrigation or trimming. Domed, covered, and partially covered stadiums may require artificial turf because of the difficulty of getting grass enough sunlight to stay healthy.

A common misconception is that the new synthetic grass is similar to the household carpet. In fact this intricate system involves properly constructing a porous sub base, and using turf with holes in the back, and then the product is filled with sand/rubber granule mix which we call infill.

Artificial turf, also known as synthetic turf, has found a prominent place in sports today. Manufactured from synthetic materials, this man-made surface looks like natural grass. With the international sports associations and governing bodies approving the use of artificial surfaces, sports like football and hockey, which were originally played on natural grass, have moved to these artificial sports pitches. So, next time, you find players playing on an artificial hockey pitch, do not be surprised.

Artificial turf has been manufactured since the early 1960s, and was originally produced by Chemstrand Company (later renamed Monsanto Textiles Company). It is produced using manufacturing processes similar to those used in the carpet industry. Since the 1960s, the product has been improved through new designs and better materials. The newest synthetic turf products have been chemically treated to be resistant to ultraviolet rays, and the materials have been improved to be more wear-resistant, less abrasive, and, for some applications, more similar to natural grass.
