Landfills

The landfill is a site used for the disposal of waste materials. The landfill is a solid waste facility that is often known as a dumping ground. The image below shows a landfill site in Hawaii. Landfilling is the most ancient and common method used for the disposal of waste. For the landfill, a deep trench is constructed in an isolated place away from the city. The trench for landfills is designed properly after analyzing the total population and the waste generation per capita. The waste is dumped into the trench and after every layer of waste, a layer of soil is spread on the top of it.

6. A tertiary treatment plant treats a municipal secondary effluent and is to employ fixed-bed carbon adsorption columns. Parallel treatment using two rows of two columns in series (in other words, a total of four columns) will be used. From batch-type slurry tests it has been found that 0.42 g COD/g carbon is adsorbed when Ce = Co. Pertinent data are as follows: flow = 5700 m³/d, COD in feed to carbon columns = 20 mg/L, contact time function based on an empty carbon bed = 30 min, and unit liquid flow rate= = 4.4 L/s-m². Each column is kept on-line until the entire mass of carbon in the column is completely exhausted. Determine: The volume of each column, m³. a. b. Page 2 of 3 C. d. e. The diameter and height of each column, m. The mass of carbon in each column if the packed density is 400 kg/m³. The kilograms of carbon exhausted per day if the COD removed is assumed to be 98%.

A BOD test is run using 100mL of treated wastewater. The initial DO of the mixture after diluting the waste sample with distilled water is 9.0mg/L. After 5-day incubation, the DO measured was 4.0mg/L. After a long period of time, the DO is 2.0mg/L and no longer seems to be decreasing. Assume that nitrification has been inhibited. Determine the following: a)BOD5 & BODu of the waste sample b) BOD5 of the mixture and c) k THANK YOU
The wastewater from a synthetic textile manufacturing plant is discharged to a municipal treatment plant for processing with domestic wastewater. The characteristics of the synthetic textile wastewater are 1500 mg/L BOD, 2000 mg/L SS, 30 mg/L nitrogen, and no phosphorus. The characteristics of the domestic wastewater are 200 mg/L BOD, 240 mg/L SS, 35 mg/L nitrogen, and 7 mg/L phosphorus. Find the BOD, SS of the mixture. The ratio of flow rate is domestic/textile = 4/1
