Top Ways to Reduce Wastewater Generation

Freshwater is one of the most precious resources on earth. Everyone can take benefit from its preservation. There are many ways in which we can reduce its wastage. There are many inefficiencies that we need to overcome to ensure that we intelligently use this rare source of life. Wastewater generation is increasing at an astonishing […]

Current Limits in Aeration Technology

Put a steel pin or a small aluminium disk gently on the surface of water and it will make a slight dent but it will stay there. It will not sink, even though both aluminium and steel have a lot higher density than water. This demonstrates the toughness of any normal water surface, where water […]

Hazards of Olive Oil Wastes

The olive oil industry offers valuable opportunities to farmers in terms of seasonal employment as well as significant employment to the off-farm milling and processing industry.  While this industry has significant economic benefits in regards to profit and jobs; the downside is it leads to severe environmental harm and degradation. Sources of Wastes Currently, there […]

How to Treat Industrial Wastewater without Chemicals

According to The United Nations World Water Development Report 2017, the volumes of industrial wastewater could double by 2025, while the market for wastewater treatment technologies is also predicted to grow as much by 2020. This shouldn’t be a surprise since wastewater can present an opportunity for cost saving and reducing water dependency when managed […]

Algae Biorefinery Project in Saudi Arabia

The King Abdulaziz City for Science & Technology (KACST) is funding an innovative project called Saudi Arabia Biorefinery from Algae (SABA Project) to screen for lipid hyper-producers species in Saudi Arabia coastal waters. These species will be the basis for next-generation algal biofuel production. The goal of this project is to increase research and training […]

Sewage Lake of Jeddah

Jeddah, one of the largest cities in Saudi Arabia, has more than three million residents. The estimated water  use is 200 liters per capita per day. Typically, 80% of potable water used  for municipal purposes returns to the environment as wastewater. Since  85% of Jeddah is not connected to sewerage pipelines, wastewater accumulates in underground cesspools […]

Advances in Aeration Turbine Technology

The future of aeration technology lies in really dynamic solutions, such as turbines. They are in jet planes and even cars, hydro power plants, steam turbines, gas turbines and as wind turbines. They convert electricity to various kinds of flow and vice versa. Surely this is where the action is, so work should be done […]

Biogas from Industrial Wastes

Biogas (or anaerobic digestion) technology is an attractive way to manage organic wastes in a sustainable manner. Organic waste includes a wide range of organic materials obtained from domestic, industrial and commercial operations. Most of the organic waste generated in developing countries is dumped into the landfills where it is not only responsible for large-scale greenhouse gas […]

Ultrasound-Activated Anaerobic Digestion of Sewage Sludge

Ultrasonic disintegration is a method for breakup of microbial cells to extract intracellular material. Ultrasound-activated sewage sludge disintegration could positively affect anaerobic digestion of sewage sludge at sewage treatment plants (STPs). Due to sludge disintegration, organic compounds are transferred from the sludge solids into the aqueous phase resulting in an enhanced biodegradability. Therefore disintegration of sewage […]

Disposal of Palm Oil Mill Effluent

Palm Oil processing gives rise to highly polluting wastewater, known as Palm Oil Mill Effluent (POME), which is often discarded in disposal ponds, resulting in the leaching of contaminants that pollute the groundwater and soil, and in the release of methane gas into the atmosphere. Properties of POME POME is an oily wastewater generated by […]

Management of Organic Industrial Wastes

Organic industrial wastes includes a wide range of organic materials obtained from industrial and commercial operation. These organic wastes, either liquid or solid, are a good substrate for biogas generation by making use of the anaerobic digestion process. Anaerobic digestion of organic industrial waste is fast gaining popularity worldwide. Sources of Organic Industrial Wastes Many […]

Wastes from Leather Tanning

Tanning refers to the process by which collagen fibers in a hide react with a chemical agent (tannin, alum or other chemicals). However, the term leather tanning also commonly refers to the entire leather-making process. Hides and skins have the ability to absorb tannic acid and other chemical substances that prevent them from decaying, make […]
