Is recycled water really safe to use and drink? Environmental Engineering 3/9/2015 [Type the company name] Satellite   A clean water is very essential not just with the environment but most especially among humans. It is important for us to know if the water we drink is clean and safe to drink because we are pertaining to our health. If we drink contaminated water, we are drinking the risk of having bacteria and viruses into our body so it is essential for us to know how safe the water we are

Can dogs eat Plum? Keywords: can dogs eat plum Plums! A delicious fruit with a lot of benefits and added nutrients is often considered a delicious treat by everyone. An all-rounder fruit which can be a great thing when mashed or when added to a pie, cookie or cake. Plum is a multipurpose fruit that is loved by everyone. However, does this saying goes fit for a dog too? Do they found this fruit as juicy and healthy as a human? Let’s find out! The answer is dogs cannot and should not eat plums but

For this lab, zeolite and magnetized zeolite were synthesized and compared with charcoal to find out with would be the most effective in the sequestering of Procion Red dye. Finding the concentration and absorbance of each zeolite, magnetized zeolite, and charcoal, along with a calibration curve, the best adsorbent is determined. Charcoal was the overall best sequestration of the Procion Red dye, since the adsorbent was highest compared to the others. Introduction Pollution has increased in the

amount of sludge(Kannan and Rengasamy, 2005). Chromium can be removed using adsorbents of natural as well as chemical origin. However, these bio-adsorbents have various disadvantages like waste may itself contain various toxicants and subsequently increase the organic content of water. Studies have showed adsorption capacities and applicability for some low-cost materials, among others like alluminium oxide, chitosan, bentonite, saw dust and waste slurry (Dubey and Gopal, 2007). Activated carbon is

Treating wastewater is extremely vital to the health and well-being of eco-systems all around the world. The treatment of wastewater is a fairly modern concept, though collection systems to remove foul-smelling water were common in ancient Rome, it was not until the 19th century that urbanized areas began to realize that removing the pollutants from the water that they were discharging into the environment was extremely important. (1) The reason that this became so relevant was a direct result

substitutes. In previous work, this waste was co-digested with an excess of activated sludge produced in the wastewater treatment plant located in same industrial unit, resulting in a very poor methane yield (25 LCH4(STP)/kgVSinitial), and low reductions in total solids (31%) and in volatile solids (40%). When the barley waste (BW) was subjected to alkaline hydrolysis pre-treatment before co-digestion with activated sludge, the methane production increased to 222 LCH4(STP)/kgVSinitial and the total

AUSTRALIAN PINE CONES-BASED ACTIVATED CARBON FOR ADSORPTION OF COPPER IN AQUEOUS SOLUTION MUSLIM A. Department of Chemical Engineering, Syiah Kuala Univeristy No. 7JalanTgk. Syech Abdul Rauf, Darussalam, Banda Aceh Indonesia Corresponding Author: abrar.muslim@che.unsyiah.ac.id Abstract The Australian Pine cones (APCs) was utilised as adsorbent material by physical and chemical activation for the adsorption Cu(II) from aqueous solution. FTIR and SEM analysis were conducted to obtain the active

In precipitation process, large volumes of sludge are generated which can present dewatering and disposal problems [11], as well as re-carbonation of the softened water are needed [3]. Ion-exchange resin have been widely used to remove calcium and magnesium ions due to their many advantages, such

strained contains carbohydrates (4–5%), lactose (45–50 g/L), proteins (6–8 g/L), lipids (4–5 g/L) and mineral salts (8–10% of dried extract). Mineral salts include NaCl and KCl (>50%) as well as calcium salts (among others). The water content of cheese whey is quite high, constituting as much as 93.12 grams out of 100 g . When dewatered, however, solids are left. 2.2.7 Corn syrup. Corn syrup (as differentiated from high-fructose corn syrup which is a different product) is one of several natural

Abstract The one of the Transnet Engineering factory that manufacture tarpaulins is facing an increase on customer demand and is about to sign an agreement with the customer about the new demands on 10 and 16 metre container covers. In order for the company to reach to that decision simulation is found to be the best method, because it can provide a clear view to assist the key decisions a company must make on contemplating new demands, or a new operations at an existing production line, to simulate
