Water Pollution Part II Amanda Norris Groundwater Pollution pg. 502: Describe : Groundwater is the water we drink. Few countries go to the great expense of locating‚ tracking‚ and testing aquifers. Volatile organic chemicals (VOCs) contaminate 90% of the U.S. aquifers‚ but 2% of samples had unsafe VOC levels. The US found that ⅓of the 26k industrial waste ponds didn’t have liners to prevent toxic liquid wastes from seeping into aquifers. The EPA had completed the cleanup of 297k of the 436k underground

company based in Perak. Since 2006‚ the transport service rendered by PHSB has been facing challenges whereby its portion of its CPO cargo is sold to illegal market by its truck drivers. To compensate the missing load‚ the weight is being replaced with sludge‚ water or used oil. This has contributed to bad quality CPO thus increasing the processing cost of the refinery and inability to meet customers specification. In 2009‚ there are 36 palm oil refining facility in Malaysia with the annual refining capacity

Photocatalytic degradation of methylene blue using TiO2 nanoparticles Nupur Mittal Chemical Engineering‚ IIT (BHU) Varanasi. Abstract: The aim of this research is to reduce the pollution caused by methylene blue dye in waste water coming from textile industries. For this purpose‚ TiO2 nanoparticles are made as they show good photocatalytic activity in degradation of dyes into harmless products. Synthesis is done using titanium butoxide and 2-propanol. The particles formed were a little larger

EFFECT OF BIODEGRADABLE SM PLASTIC BAG IN DIFFERENT SUBSTRATE ABSTRACT The purpose of this Investigatory project is to determine the effect of different substrates on the biodegradability of SM plastic bags. The materials needed are: 6‚ 1-litre glass jars; 6‚ 7”x9” aluminums trays; 12 pcs. 3”x4” SM plastic bags; 500g loam soil; 500g compost soil; 500mL seawater; 500mL tap water; Analytical balance; Graduated cylinder; and Weighing scale. The procedure involved cutting the SM plastics bags

affiliation and the similarity of the bands marked in Fig. 4a which shows the bacterial DGGE fingerprint obtained when ferrous sulfate was used as the energy source (batch-1). Initial sludge had 18 dominant bands out of which 7 bands were not detected on the 2nd day (Fig. 4a) due to changes in the physical condition of the sludge such as aeration and the pH decrease. Dynamics in the microbial community profiling was studied using UPGMA analysis and Figure 4b depicts the organization of the clusters when

The strain of C. testosteroni bdq06 (NCBI No. KM277791) was isolated from active sludge in the 86 wastewater treatment plant of Jilin Petrochemical Company (China) and cultured in a mineral medium as 87 described previously with quinoline as the sole carbon‚ nitrogen and energy source(Geng‚ et al.‚ 2015). It 88 has the ability to completely degrade quinoline into carbon dioxide and water‚ and convert nitrogen in 89 pyridine ring into ammonia‚ nor into nitrite(Geng‚ et al.‚ 2015). 90 91 2.2. Reactor

Inlet Screens Water should be screened before entering the tank to reduce the introduction of contaminants which could foul or discolour the water and contribute to the build-up of sludge. Larger contaminant material can be filtered from water entering a tank by a suitably fitted gauze mesh screen. Various in-line screens and filtering devices have been marketed in South Australia.

important feature of lamella settlers‚ are series of inclined plate which the suspended particles goes down with water flow‚ where solid particles start to settle on the plates and begin to accumulate in collection part of the bottom of the unit. Sludge is drawn off at the bottom and clarified water exists from top of the unit. • Then water enters the UF chamber which is one simple step
