The choice of coagulants and coagulant dosage depends on raw water quality, which varies from one reservoir to another, on the occurrence of rains or alga blooms.
The Clearlogx technology is a proprietary technology developed by Gregg McLeod, director and shareholder of Clearlogx, which precisely and continuously controls the feed of specialty coagulants used in water treatment to maintain a proper pH level and an optimum particle charge, while simultaneously improving overall treatment process efficiency.
The results showed that using poly aluminum chloride, ferrous sulfate, ferric chloride and Aluminum Sulphate coagulants in 50, 20 and 10 NTU turbidities reduces PH, so that for adding each mg of poly aluminum chloride, ferrous sulfate and ferric chloride coagulants, PH reduces about 0.
In a research,[5] examined efficiency of conventional coagulants and auxiliary coagulants in pretreatment operations of raw water behind Gavashan Dam, Kermanshah.
Common coagulants like alum and iron salts have been widely used in conventional water treatment process [6].

The application of natural coagulants is based on their traditional use in tropical, rural areas.
In the present work, new inorganic coagulant named "Agoclean P" has been developed from paper sludge ash.
Similarly, additional methods for treatment of water after being clarified with natural coagulants have not yet been explored.
The formation of the hydrolytic products formed from metal salt coagulants occurred in a very short time and they are readily absorbed onto the colloid particles and then cause destabilization of their electrical charge.
Tasked with replacing ageing pumps for disinfectant and coagulant processes at Thames Water's Advanced Water Treatment Works (AWTW) in Walton, Surrey, engineering, consulting and construction company Black & Veatch opted to install a number of 520 series and 620 series peristaltic models from Watson-Marlow Pumps Group.
