Activated Sludge Process will encompass * Design of aeration basins. Relevant design parameters are * BOD load from the upstream process * Mixed Liquor Suspended Solids Concentration (MLSS – mg/l) – typically 2‚000 to 4‚000 * Sludge Age 5 to 25 days * Sludge settleabiltiy (SVI ml/g) typically 100-120 * Process Oxygen Demand (POD) * Generally fine bubble diffusers used in modern plant design – actual oxygen transfer efficiency dependent

discrete time linear time invariant (LTI) systems. Further‚ it introduces Z-transform and its inverse and followed by their applications to the analysis of LTI systems. A framework for designing analog and digital filters (both FIR and IIR) is introduced starting with mapping of filter specifications from continuous Laplace transformation to Z-transform‚ structure realization based on Direct‚ Cascade‚ and Parallel forms‚ analysis of finite precision effects‚ and ultimately implementation and testing

Well‚ when your homes own water pressure pushes the water through the membrane‚ and subsequent sediment and carbon filters‚ the impurities are simply filtered out once again and flushed down your drain. All you’re left with is delicious‚ clean‚ crisp tasting drinking water. To gain this result‚ many RO systems‚ including our own‚ adopt a 4-5 stage filtration process and

This reputation was at stake due to the decline in sales and consequently losing its strong share position in the market. • Heightened pressure from competitors. There were many competitors who entered the market but failed to succeed against Brita. Many competitors came up with the similar kind of filters but unable to succeed due to strong branding

Chomsky is known to be the father of linguistics. He is an American linguist and political critic who created along with Edward S. Herman a set of five filters known as the propaganda model. These five filters discuss and focus on how power along with wealth effect the media and what we as general public receive as our daily news. The five filters are consisted of Size‚ Ownership‚ and Profit Orientation of the Mass Media‚ The Advertising License to Do Business‚ Sourcing Mass Media News‚ Flak and

We use the second flask so between the aspirator and our filter flask so that the filtrate will not become contaminated if tap water is pulled back through the hose.] Place a piece of filter paper into the Buchner funnel so

low bit rate speech analysis technique for encoding a speech signal. The source filter model used in LPC is also known as the linear predictive coding model. It has two main components LPC analysis (encoding) and LPC synthesis (decoding). The goal of the LPC analysis is to estimate whether the speech signal is voiced or unvoiced‚ to find the pitch of each frame and to the parameters needed to build the source filter model. These parameters are transmitted

Describe and evaluate two or more theories of the formation of romantic relationships (8+16) One theory put forward for the formation of romantic relationships was by Murstein – called the Matching Hypothesis. Murstein argued that we all desire the best looking person; however we accept that this may not happen‚ so we go for people with a similar attractiveness to ourselves. It makes us far less likely to suffer rejection. So‚ in theory‚ Murstein’s argument is fundamentally based on physical attractiveness
