Typical filtration rate for rapid sand filter is 5 m/h, compared to m/h in slow sand filtration. The area required for sand filtration can be calculated using the following equation: A = Q/V. Where, A is the filter area in square meters (m 2) Q – Inlet water flow rate in m 3 /h. V – filtration velocity in m/h . We can use this equation to compare the required filtration area between

In subsequent steps the phosphoric acid is clarified and concentrated by thermal evaporation to drive off more than half the water from the
· How To Control Gypsum Scaling In High and Low PH Waters. Unlike other types of scaling, CaSO 4 is pH independent. That means that the addition of an acid or alkali will have no effect in preventing scale formation. Genesys has developed two new antiscalants – Genmine AS26 and Genmine AS65 – which are capable of inhibiting CaSO 4 at both low
Brine is a high-concentration solution of salt (NaCl) in water (H 2 O). In diverse contexts, brine may refer to the salt solutions ranging from about % (a typical concentration of seawater, on the lower end of that of solutions used for brining foods) up to about 26% (a typical saturated solution, depending on temperature).Brine forms naturally due to evaporation of ground saline
· Due to the filtration of soil particles,In Pakistan, mostly people useThe results showing dominance of Na-Cl water are an indication of typical marine and deep ancient groundwater. Apart from role of rock dissolution and weathering (primary factors), hydrogeochemistry of groundwater is also regulated with climatic factors. Therefore,
SO 2 is an acid gas, and, therefore, the typical sorbent slurries or other materials used to remove the SO 2 from the flue gases are alkaline. The reaction taking place in wet scrubbing using a CaCO 3 slurry produces calcium sulfite (CaSO 3) and may be expressed in the simplified dry form as: . CaCO 3 (s) + SO 2 (g) → CaSO 3 (s) + CO 2 (g). When wet scrubbing with a Ca(OH) 2

· With HEPA air filters, it depends on the actual real-world efficiency of the air filter (%), the volume of media within the filter, and the dirt load. Generally speaking, a HEPA air filter in an air purifier should last at least 18 months. Air purifiers that guarantee a service life of 5 or 10 years should be carefully evaluated as that is questionable in a typical environment.
