Heating, ventilation, and air conditioning (HVAC) system is designed to achieve the environmental requirements of the comfort of occupants and a process. HVAC systems are more used in different types of buildings such as industrial, commercial, residential and institutional buildings. The main mission of HVAC system is to satisfy the thermal comfort of occupants by adjusting and changing the outdoor air conditions to the desired conditions of occupied buildings. Depending on outdoor conditions, the outdoor air is drawn into the buildings and heated or cooled before it is distributed into the occupied spaces, then it is exhausted to the ambient air or reused in the system. The selection of HVAC systems in a given building will depend on the climate, the age of the building, the individual preferences of the owner of the building and a designer of a project, the project budget, the architectural design of the buildings.

Chemicals are produced with high-quality raw materials, purity analyses, strict quality control, storage of samples for all production batches and jar testing to ensure maximum performance. Our industrial water treatment chemicals provide complete solutions for any water condition requirement: Physical pre-treatment of water: settling, filtration, etc. Physicochemical pre-treatment of water: reverse osmosis, resins, etc. Treatment of energy carrying fluids: cooling towers, boilers, etc. Process water production Effluent and sludge treatment, etc. Click Here for PDF Sample Copy of Water Conditions Industrial water treatment chemicals meet a variety of purification and separation needs in system. They can range from relatively compact and straightforward to complex, multiunit processes that serve a variety of applications. An industrial water treatment chemical treats water so it is more appropriate for a given use, whether for consumption, manufacturing, or even disposal. That said, eac...

Packaging Services aims at the convenience of the end-user customers by offering convenient, durable, and service packaging. Such packaging is widely used across various applications such as food, beverages, and consumer goods. A service package is a bundle of services that are sold together as a unit by a company. Service packaging market has witnessed a significant growth owing to factors such as rising demand for industry. Moreover, the technological advancement provide a huge market opportunity for the key players operating in the service packaging market. However, volatile prices is projected to hamper the overall growth of the service packaging market. It is clear that packaging plays a large role in the perceived value of a product and as a whole, the packaging industry really hasn’t changed too much in the past years, compared to the constant innovations made in portable technology. With all the packaging and box choices available in today’s market, it often becomes difficult t...

Composite rebars are a substitute for the conventional steel rebars, which are used to provide a non-corrosive reinforcement to concrete and add service life to it. They can be up to 75% lighter than the traditional steel rebars, which makes it easy to carry and transport. They are light-weight, rust and corrosion-proof, and flexible, which allows for a higher degree of freedom in building designs. Composite bars are used in weight-sensitive applications, and environmentally sensitive areas where moving heavy equipment is undesirable. They are gaining acceptance in a number of major applications, including industrial engineering, highway construction, railway construction, residential construction, etc. Click Here for Design Guide PDF Copy: Concrete has long been used as a building material for its high compressive strength, good durability and low cost. However, its well-known Achilles’ heel is its brittleness and limited tensile strength. This was solved quite handily about a century...

Nowadays the biomass pellet manufacturing industry booms, so unavoidably there are sellers who sell bad quality pellets at best quality prices, which greatly harms customer’s interests. However, for most pellet users, they only keep in mind that the higher price it is, the better quality pellets have. The raw material for biomass pellets making varies from wood sawdust, stalk, peanut shell, cotton stalk, corn stalk and straw, to household garbage. While wood pellets have the highest combustion value, then are stalk pellets, and household garbage pellets are the worst.

Coal has the largest carbon dioxide emissions per unit energy of all fossil fuels, and coal-fired power plants are a major source of man-made carbon dioxide emissions. Coal-fired power plants generally have a life of 20 to 50 years and represent a huge global capital investment. It is not economically feasible t...

An increasing amount of waste is generated each year from textiles and their production. For economic and environmental reasons it is necessary that as much of this waste as possible is recycled instead of being disposed of in landfill sites. In reality the rate of textile recycling is still relatively low. On average, approximately ten million tones of textile waste is currently dumped in Europe and America each year. Considering the diversity of fibrous waste and structures, many technologies must work in concert in an integrated industry in order to increase the rate of recycling. Recycling in textiles shows how this can be achieved. The first part of the book introduces the subject by looking at the general issues involved and the technologies concerned. Part Two explores the chemical aspects of textile recycling. Part Three focuses on recycled textile products, including nonwovens and alternative fibres. Finally, the last part of the book discusses possible applications of recycle...

While fracking has produced cheap natural gas in the US, it has also increased competition for water, which is in short supply across many parts of the country. The process — injecting a high-pressure mix of water, sand and chemicals into rock formations to release natural gas — uses vast amounts of it. A single well can use between 65,000 gallons and 13 million gallons of freshwater. This has led to new regulations that focus on water conservation as well as an increased focus on treating and recycling fracking wastewater. Click Here to Know What are the New Technologies About half of the freshwater used in fracking is recovered as “flowback,” or water that flows back to the surface along with natural gas. The process also yields produced water, which contains massive amounts of brine. This wastewater mixture is difficult and expensive to treat, which is why it is typically injected deep underground. Regulations are limiting deep well injection of produced water, currently very common...
