The influence of different humic substances and linear alkylbenzene sulfonate on chemical treatment of a synthetic wastewater was investigated at pH=6-6.5. In soft water, humus significantly inhibited particle destabilization. The additional coagulant dosages needed for efficient coagulation corresponded to the dosages required for humus removal from pure solutions. Adsorption of humus onto precipitated hydroxide was regarded as being the major mechanism of interaction here. In hard water, high concentrations of humus seemed to impair aggregation of microflocs. This was attributed to the formation of soluble calcium humate complexes in raw water that may adsorb more slowly on precipitated hydroxide than dissolved humus. Precipitation of phosphate was not affected by humus in a definite way. A clear influence of LAS on coagulation was not found.

In the manufacture of detergents still using surfactants (which serves as an emulsifier) of crude oil in the form of the AS. (alcohol sulfate) and LAS (linear alkylbenzene sulfonate), where this type of surfactant cannot be degraded by microorganisms when discharged into the environment, causing environmental pollution. Methyl ester sulfonate surfactant is an anionic surfactant which has a composition of C16 - C18 fatty acids are capable of acting against nature deterjensinya, while the C12 - C14 fatty acids contribute to the foaming effect. The purpose of this study was to look for the formulation of methyl ester sulfonate (MES) the right to produce a good detergent by using materials such as methyl ester sulfonate surfactant self-made, methyl ester sulfonate and sodium lauryl market Ester Sulfate (SLS) with a concentration of 15 %, 20 % and 25 %. Detergent results of the study have high detergency ( net ) compared with the detergency of detergent commercial, have a stable emulsion stability, the stability of the foam/foam detergent power made from methyl ester sulfonate surfactant produces less foam, compared with a detergent made from SLS and surfactant SNI 06-4075-1996 standards.
