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.

My question is in the picture
Activated carbon is being used in a batch process to remove pesticides from a rural water supply. After each batch of water is treated, the carbon particles are allowed to settle, the water is drained off, and a new batch of water is mixed with the carbon. The adsorption is known to follow a Langmuir isotherm. After a number of batches of water have been treated in this way, the adsorption density on a sample of the activated carbon is given by: q ¼ (qmax/Kadscin)/ (1 + Kadscin), where cin is the pesticide concentration in the untreated influent water. The value of q under these circumstances is much less than qmax. Do you think that the removal efficiency of pesticide in the next batch of water to be treated will be good or poor? Explain briefly.
