Types of Cement

Cement is a fine mixture of limestone, chalk, or marl and clay which when mixed with water, becomes compacted due to the formation of strong molecular bonds. Due to hydration, cement turns into a hard mass when left for a sufficient amount of time upon mixing with water. The water turns the cement compounds into gel-like submicroscopic particles having higher surface areas. It is due to the hydration properties of cement, they are often known as hydraulic cement. For instance, Portland cement is a popular example in this category.

Membrane filtration, operated in a dead-end mode, is used to treat secondary effluent. If the HPC in the effluent increased from 5 org/L to 200 org/L, after an extended period of operation, estimate the number of broken fibers for the following conditions. The influent flowrate and organism count are 4000 m3/d and 6.7×107 org/L, respectively. The membrane bundle contains 5000 individual fibers. If the influent and effluent turbidity values under normal operation are 4 and 0.25 NTU respectively, estimate the increase in the effluent turbidity assuming the increase could be measured.
