Flocculant management. Flocculants are often the biggest contributor to the operational costs of the thickeners; therefore the objective is to minimise flocculant consumption without compromising thickener performance. The general assumption that some is good and more is better does not apply to flocculant addition.

What is worse is the corrosion process dissolves some of the metal into the pool water. For parts that contain copper, like metal piping in older pools and copper heat exhangers in pool heaters, small amounts of copper from these surfaces will be released into the pool water.

Flocculants are polymers that promote flocculation by formation of bridges between themselves and solid particles, promoting suspended particle to aggregate. As suspended particles are flocculated into larger ones, they are settled in devices like thickeners and removed with the underflow.
This product is used as a flocculant which attracts suspended particles in the water together (green or cloudy pools). Alum sinks everything to the bottom, which is then vacuumed to waste. A small amount of alum can also be used as a sand filter additive. Dosage: 4-12 lbs per 10,000 gallons
flocculant for copper oxide. polyacrylamide is widely used as a flocculant or filter aid in mining minerals such as gold, silver, copper, aluminun, iron, tin, coal, lead, zinc. Get Price
Alum, short for aluminum sulfate, is a flocculant, meaning that it attracts and traps suspended particles in the water and then sinks them to the bottom of the pool so that these particles can be vacuumed out. Quite often after using alum most pool owners will find the water to be crystal clear with the exception of a solid layer of the chemical and particles on the very bottom of the pool.
Huntsman coagulants are designed for use in the mining industry for the treatment of fine. particles in aqueous suspension. Polyether coagulants are one of the few that are effective. against the colloidal silica formed during the acid leaching of ores or slags containing. silicates.

Introduction of flocculants: Flocculants are a reagent added to a dispersion of solids in a liquid to bring together the fine particles to from floc.. The flocculants are generally classified as natural flocculants and Synthetic flocculants.. Natural Flocculants: They are water soluble anionic, cationic, non ionic polymers.Non ionic polymers adsorb on the suspended particles The most common ...
Use BAQUACIL Flocculant as a broadcast flocculant if the pool''s Haze Rating is a 3 or 4 and it is possible to vacuum the pool to waste. 3 = Pool is hazy, main drain or pool bottom is not visible. 4 = Pool is hazy, no depth visible. FLOCCULANT & FILTER AID REFERENCE SHEET in a BAQUACIL® Pool Visit us as SAP# 49308
Slowly add recommended amount of Baquacil Flocculant listed in table directly to skimmer while pump is running. Filter continuously for 48 hours checking back pressure periodically. In the event of high filter pressure, backwash and rinse filter according to manufacturer''s recommendations. If pool is still not clear, repeat steps 3 and 4.
Test Conditions. Glaze batch: Each test was 300g, with a tablespoon of epsom salts added as a flocculant. Glazing method: Hand dipping. First dip (bottom half): 3 seconds. Second dip (top half) additional 4 seconds on top of the first layer, total 7 seconds.
Ferric Chloride. Ferric chloride is the coagulant of choice for many industrial and sanitary wastewater treatment applications, due to its high efficiency, effectiveness in clarification, and utility as a sludge dewatering agent.

studies of wastewater treatment at 6 metal electroplating plants revealed that a ph of 9-10, a polymeric flocculant, and a conventional clarifier-sludge system were the most effective treatments. reaction times were greatest for the oxidation of nickel cyanide, followed by copper cyanide, & then zinc cyanide.
Natural polymers have long been used as flocculants. For example, Sanskrit literature from around 2000 BC mentions the use of crushed nuts from the Nirmali tree (Strychnos potatorum) for clarifying water – a practice still alive today in parts of Tamil Nadu, where the plant is known as Therran and cultivated also for its medicinal properties.
Treatment was needed for waste streams containing high concentrations of potassium persulfate, copper sulfate, ammonium chloride/hydroxide, and pyrophospate, with copper concentrations ranging from 20,000 to 150,000 ppm.
Different flocculants work in different ways but all encourage the suspended particles to cluster together into ''clumps''. These ''clumps'' sink to the bottom of the pool faster. Generally speaking application of a flocculant will clear the water overnight. Application and removal of flocculants
There are a few ways to do this, first off you could raise the pH a bit to precipitate it out as copper oxide - typically use lime or limestone for this. You could add a sulphidising reagent like sodium metabisulphite or sodium hydrosulphide, this will precipitate out a sulphide, but the reagents can be a .
