The direct effect of ,salinity, includes the osmotic effect affecting water and nutrient uptake and the toxicity or deficiency due to ,high, concentration of certain ions. The plan of action to resolve the problems associated with ,soil salinization, should focus on prevention of salt accumulation, removal of accumulated salts, and adaptation to a saline environment.

The levels of pH in water can be impacted by external factors such as temperature, ,salinity, and rainfall. If a body of water ,is high, in alkalinity, it can limit or minimize the impact on pH when these naturally occurring factors occur. This is why water from unique places like Hawaii are ,alkaline,.

High salinity, in ,wastewater, led to a large increase in the suspended solids value by 330.2 mg/L due to salt deposition, which is a potential problem to be considered for ,high salinity wastewater,. Settling tests and particle size distribution showed that HPAM or CPAM flocculants played an important role in enhancing the particle settling and enlarging the particle size compared to PAC.

The ,high salinity, of industrial dairy effluents causes a non-volatile suspended solid content increase in the primary and secondary sludge. Inorganic impurities in dairy ,wastewater, are represented by Na + , K + , Ca 2+ and Cl¯ ions, with their highest amounts in cheese and cottage cheese production (0.46–10%), mostly NaCl and KCl (>50%) as well as Ca 3 (PO 4 ) 2 , where salt is added in ...

The test for pH value of ,wastewater, is carried out to determine whether it- is ,acidic, or ,alkaline, in nature. Fresh sewage is generally ,alkaline, in nature, (its pH value between 7.3 to 7.5). However, as the time passes, pH value tends to fall due to production of acids by bacterial action, and the sewage tends to become ,acidic,.
