Manual for testing of water and wastewater There are some recommended tests available for the assessment of some of these chemicals, such as the South African Bureau of Standards 459-1955 Standard Specification for Lime for Metallurgical Purposes, but the tests described in this specification are for the most part outdated gravimetric procedures which are time consuming. Manual for testing of water and wastewater treatment chemicals. AWWA, the American Society for Testing and Materials ASTM and the Council of Chemical.
Methods for Chemical Analysis of Water and Wastes - epa In potable water treatment chemicals such as inorganic salts and polymeric organic coagulants are used for primary coagulation, as coagulant aids and for sludge dewatering; lime and soda ash allow for p H correction and water stabilisation; caustic soda is used for p H adjustment; powdered activated carbon (PAC) can remove taste and odour compounds and micropollutants such as atrazine; bentonite aids coagulation; and ammonium hydroxide is used in coramination. Method 418 1 Phenolics, Total Recoverable Spectrophotometnc, Manual 4-AAP. Complete and unequivocal preservation of samples, either domestic sewage. on sampling water and industrial wastewater may be found in ASTM, Part 31.
Summary of Pretreatment Options - Dow Chemical Wastewater treatment is generally performed using a predominantly biological process in South Africa, but here too chemicals are often used, such as coagulants for sludge conditioning, lime for p H adjustment and to increase the alkalinity content, and aluminium and iron salts for phosphate removal.
