Coagulants for Farm Sewage Treatment in UK

The modification and use of clays as coagulants for wastewater treatment were investigated in this study. The raw clays were montmorillonites K10 and KSF, and were modified by polymeric aluminium (Al) or ferric (Fe) and/or Al/Fe mixed polymeric species. The comparative performance of modified clays and aluminium sulphate and ferric sulphate were evaluated in terms of the …

The most commonly used inorganic chemical coagulants in water treatment. Aluminium sulfate is the most commonly used chemical for coagulation in wastewater treatment. Additiude sodium aluminate, ferric sulfate, and ferric chloride. Aluminium Sulfate. Aluminium sulphate is the most widely used aluminium coagulant.

coagulants include alum, ferric chloride, calcium carbonate as well as polyaluminium chloride were generally used in the wastewater treatment [3]. Despite that, such treatment leads to disposal problems as the sludge obtained after the treatment using aluminium salts risks accumulation in the environment [4].

1. Taking the wastewater away. Whenever you flush the toilet or empty the sink, the wastewater goes down the drain and into a pipe, which takes it to a larger sewer pipe under the road. The sewer then joins our network of other sewers and takes the wastewater to a sewage treatment works. At the sewage works, we pass the wastewater through ...

Jul 01, 2004 · The coagulation jar test experiments were conducted at a site laboratory of Manor Farm Sewage Treatment Works of Thames Water. Sewage samples were taken from the crude sewages. The dosages of clays were 400, 600, 800, 1000, 1200 and 1400 mg l −1 , respectively, and the dosage of AS and FS was 3, 6, 9, 12, 15 and 18 mg l −1 as Al, or 6, 12, 18, 24, 30 and 36 …

In bulk water treatment, the jar tests are repeated with varied alum dose until the ideal dose is found. The needed dose varies with the pH of the water and the size of the particles. The usual range of alum dose is 10 to 50 mg/L of water. FEEDING DEVICES; A well engineered feeding device is an integral part of an effective water treatment program.

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.
