The procedure involved cutting the SM plastics bags into 3”x4” sizes strips. Label the strips into C1‚ C2‚ C3 for compost soil‚ L1‚ L2‚ L3 for loam soil‚ S1‚ S2‚ S3 for seawater and T1‚ T2‚ T3 for Tap water treatments. Then determine the initial weights of the plastic strips in grams using the

Today‚ current desalination methods require large amounts of energy which is costly both in environmental pollution and in money terms. Many studies of water desalination costs appear regularly

In this study‚ the proponents aimed to establish the effects of Maluggay leaves and seed respectively on seawater. Aside from its potential as biofuel feedstock‚ the seed of moringa‚ locally known as malunggay‚ could also be used for purifying water. Researchers said that seed kernels of malunggay have important amounts of water soluble protein that hold a

desalination of water water‚ desalination of‚ process of removing soluble salts from water to render it suitable for drinking‚ irrigation‚ or industrial uses. The principal methods used for desalination include distillation (or evaporation)‚ electrodialysis‚ freezing‚ ion exchange‚ and reverse osmosis. In distillation saltwater is heated in one container to make the water evaporate‚ leaving the salt behind. The desalinated vapor is then condensed to form water in a separate container. Although long

excess carbon dioxide in the atmosphere that we don’t see or feel because its effects are happening underwater. When carbon dioxide is absorbed by seawater a chemical reaction occurs that reduces the seawaters pH‚ carbonate ion concentration‚ and saturation states of biologically significant calcium carbonate minerals. It decreases the pH of seawater‚ meaning it increases the seawater’s acidity. Over the past 250 years‚ ocean acidity has increased by 30 percent. At least one-quarter of the carbon

“What’s that Awful Smell”? - Bromine There are 118 known elements to man‚ and each of them differ in its own way. They vary from weight‚ structure‚ color‚ and much more‚ but many of them are similar to others and can be grouped accordingly. One element that varies drastically from others is one whose stench is so horrible‚ that the original name of the element was changed from muride to bromos‚ which means “stench” in Greek. Thus‚ bromine was named. Like many other known elements‚ bromine was discovered

There will be three groups of jars with each group containing 3 jars each; group 1 will have one brine shrimp‚ group 2 will have two brine shrimps‚ while group 3 will be the control‚ already filled with the required concentration of algae and containing no brine shrimp. Fill the group 1 and 2 jars with 46.68 mL of seawater and 3.32 mL of algae‚ taken from the 25‚000 cells/mL jar of algae. Be sure

OCEAN THERMAL ENERGY CONVERSION Abstract Ocean Thermal Energy Conversion (OTEC)‚ to me‚ is the developing worlds answer to OPEC (Organization of Petroleum Exporting Countries). We will no longer have to depend on oil supplies from other countries. OTEC is an efficient‚ clean process‚ which utilizes the difference in temperatures between the oceans surface and its depths to produce energy. The ocean thermal energy conversion process works something like a refrigerator in reverse. The
