What is Aquaponics and How Does it Work? [PDF]

Image
Aquaponics is a combination of aquaculture, which is growing fish and other aquatic animals, and hydroponics which is growing plants without soil. Aquaponics uses these two in a symbiotic combination in which plants are fed the aquatic animals’ discharge or waste. In return, the vegetables clean the water that goes back to the fish. Along with the fish and their waste, microbes play an important role to the nutrition of the plants. These beneficial bacteria gather in the spaces between the roots of the plant and converts the fish waste and the solids into substances the plants can use to grow. The result is a perfect collaboration between aquaculture and gardening. Download PDF Copy of this Study Here Benefits of aquaponics: 1) Aquaponics is a way to grow your own fish and vegetables at the same time. You feed the fish and the fish will feed your plants through their waste output. 2) There is no need to use fertilizers because the fish provide rich nutrients for the plants. 3) In aquap...

Selection Guide for Secondary Water and Wastewater Treatment Equipment [PDF]

Image
Wastewater treatment equipment is used to treat, remediate, and process effluent wastewater. By definition, Wastewater Treatment Plant aerial imagewastewater carries a mixture of dissolved or suspended solids from residences, agriculture, and industries. Some wastewater is polluted, meaning that industrial wastes, chemicals, toxins, or other objectionable materials are present in sufficient quantities to cause a measurable degradation of water quality. Often, wastewater treatment equipment is used at sewage treatment plants, facilities that use a series of tanks, screens, filters, and other processes to remove dissolved and suspended solids from wastewater. Wastewater treatment equipment may also be used commercially, typically in conjunction with aboveground or sub-surface systems such sewers, disposal wells, and waste ponds.

What You Should Know About the Biochar [PDF]

Image
Biochar is a charcoal-like material that is produced from plant materials such as grass, agricultural and forest residues that are decomposed at high temperatures, often during renewable energy production. During the process, the physical and chemical properties of the plant material change into a highly porous, stable, carbon-rich material known as biochar. Recent research suggests it has the potential to be used as a soil conditioner and as a container substrate amendment in agriculture and horticulture, and it may improve several soil and substrate physical, chemical and biological properties. Click Download PDF Brochure   Potential Use of Biochar as an Amendment Adding biochar to soil or container substrate has several potential benefts, such as modifying soil physical and chemical properties by: • Increasing cation exchange capacity (CEC). • Increasing surface area. • Increasing pH. • Increasing plant nutrient availability. • Enhancing water-holding capacity. Biochar is a Powe...

Everything You Need to Know about Hydrogen Storage Alloys [PDF]

Image
Hydrogen is readily incorporated in hydrogen storage alloys, and when the concentration of hydrogen in the alloy comes to a certain limit, metal hydrides are formed. As a result, hydrogen occupies certain sites among the metal lattices.  The properties of hydrogen storage in an alloy are determined by the interaction of hydrogen with metal atoms at the interstitial site, and hence, the hydrogen storage characteristics depend largely upon the crystal structure of the alloy. Click to Download PDF Brochure The main functions of hydrogen storage alloys include: (1) energy conversion; (2) hydrogen separation, purification, and recovery; (3) hydrogen isotope separation; (4) catalysis; (5) alloy sensors; (6) alloy batteries; and (7) hydrogen storage and transport. Hydrogen storage alloys are classified into intermetallic compounds of several types such as AB5, AB2, AB, and A2B. Where group A elements basically consist of La, Ti, Zr, Mg, etc. and B consist of Ni, Co, Fe, Mn, etc. whose hyd...

An Ultimate Guide to Forward Osmosis Technology in Wastewater Treatment [PDF]

Image
  In recent times, membrane technology has proven to be a more favorable option in wastewater treatment processes. Membrane technologies are more advantageous than conventional technologies such as efficiency, space requirements, energy, quality of permeate, and technical skills requirements. The forward osmosis (FO) membrane process has been widely applied as one of the promising technologies in water and wastewater treatment. Forward osmosis uses the osmotic pressure difference induced by the solute concentration difference between the feed and draw solutions.   Downlaod PDF Copy of  An Ultimate Guide to Forward Osmosis Technology in Wastewater Treatment  The FO membrane process is a promising process for drinking water purification and wastewater treatment technology due to its excellent high rejection rate performance and relatively low membrane fouling characteristics. Hence it is likely to gain an very important place in the membrane technology. What is forward...
