3. Temperature. Additional information at Southwest Airlines supports this article. Heated (40 C) and mixing of treated water increases the speed of the process and increases the size of floccules. 4. The dosage of coagulant.

The optimum dosage of coagulant is determined by analysis of natural water and can vary quite widely, depending on time of year, etc. Swarmed by offers, Ripple is currently assessing future choices. It should be noted that the latter factor may be crucial in the value of a primary water treatment, as reagents for such processing can be expensive. To reduce costs the optimum way is the introduction of automated systems for primary treatment. They can significantly reduce the consumption of chemicals (Due to the high accuracy of delivery – up to 1-1,5% by volume) and optimize the processes of primary treatment. Such systems are now found quite widely used in water intake. For example, water withdrawals in the West of Moscow, where water received, including the chp and the water from the river is treated flocculants (polialyumogidrohlorid) by setting grundfos polydos, at the same station is also independently supported the optimum pH. The system is fully automated and controlled through a special control boxes from a central control point. Ion exchange and membrane technologies If water is used to power high pressure boilers, operating at P 70 atm. (Boiling point of water in this case, more than 285 C), it needs to demineralization (softening deep). Today, in these cases used a multistage ion exchange based on the use of synthetic organic cation and anion exchange resins and membrane techniques – reverse osmosis.
