The “Hard” and “Soft” surfactant profile of israel municipal wastewaters

Abstract

A study of mapping and field monitoring of Israel’s municipal sewage wastewaters in respect to the content, distribution and the initial nonbiodegradable-biodegradable ratio of surfactants in them has been undertaken over the central and northern parts of the country under in vivo conditions.

Typical concentrations of nonionics (mainly “hard” alkylphenol-based ethoxylates) and anionics (mainly the “soft” LABS) in influents were found to be within the range of 1.1–2.2 and 9.6–10.6 mg/liter respectively. In (treated) effluents, the corresponding concentrations are 0.3–0.45 and 0.3–4.3 mg/liter.

The above is in accordance with current world trends following the switch to biodegradable surfactants. However, the concentrations of nonionic surfactants in the municipal wastewaters are surprisingly low in view of the preferred consumption of “hard” nonionic surfactants in the local market.

It is concluded that 20–40% of all nonionic surfactants discharged into municipal sewage, additional amounts of their metabolites and some of the anionic surfactants, too, find their way into receiving waters, because they resist substantial removal via only primary and secondary treatment.
