It's called "micro" to the living species of very tiny sizes. It is very common the presence of these species in the wastewater contaminants, so it is important to know for successful water treatment.

These bodies are not considered plants nor animals. They are located in another kingdom called Protista kingdom and live in the wastewater.

World production of cement has a high specific emissions of CO2 (about 0.9 kg CO2 per kg of clinker) with a 5% contribution to global emissions of anthropogenic CO2. These emissions can be reduced substantially by using solar energy in the thermal decomposition of lime, which is the main step endodermal cement production.

CaCO3 CaO + CO2 = 178 KJ / mol (T = 900 ° C)

This reaction is highly endodermal (DH ≈ 477 kWh / ton CaCO3) which is why the cement industry requires high thermal energy input (approx. 0.9 kWh per kg of product). As a result, it may make sense to integrate solar thermal energy in industrial production of cement, based on cyclonic type reactors located in the center of Central Receiver System. This reactor can be opened to the atmosphere (no window open) since the calcination reaction can occur in air and the effective absorption of concentrated sunlight can be achieved by forming a cloud of gas and particles found inside turning the reactor cavity.
