An Overview of Ceramic Wastes Management in Construction
... Naceri and Hamina [45] investigated the use of waste brick as a partial replacement for cement in the production of cement mortar. Clinker was replaced by waste brick in different proportions (up to 20 % by weight) for cement. The results obtained show that the substitution of cement by 10% artificia ...

... Now, add a Constant [Tributary] Load of 0.1 mg/L. Note that the authors’ use of the word Load here is incorrect. Run the simulation and examine/explain the result. Try it again for an Initial Condition of 0 mg/L and 0.2 mg/L. Try doubling and halving the load. Seek to resolve your intuition and the ...

Secondary treatment
Secondary treatment is a treatment process for wastewater (or sewage) to achieve a certain degree of effluent quality by using a sewage treatment plant with physical phase separation to remove settleable solids and a biological process to remove dissolved and suspended organic compounds. After this kind of treatment, the wastewater may be called as secondary-treated wastewater.Secondary treatment is the portion of a sewage treatment sequence removing dissolved and colloidal compounds measured as biochemical oxygen demand (BOD). Secondary treatment is traditionally applied to the liquid portion of sewage after primary treatment has removed settleable solids and floating material. Secondary treatment is typically performed by indigenous, aquatic microorganisms in a managed aerobic habitat. Bacteria and protozoa consume biodegradable soluble organic contaminants (e.g. sugars, fats, and organic short-chain carbon molecules from human waste, food waste, soaps and detergent) while reproducing to form cells of biological solids. Biological oxidation processes are sensitive to temperature and, between 0 °C and 40 °C, the rate of biological reactions increase with temperature. Most surface aerated vessels operate at between 4 °C and 32 °C.
