The effects of changing dose of
clay, pH and temperature were explored on percent removal.
Treatment is considered using natural local materials (bentonite). The
work centered at determining optimum conditions for car wash
wastewater treatment using Aleppo bentonite. Acquired results would
provide many benefits to Syria, including preservation of water
resources and reduction of water pollution. As well as the economic
benefits to be a major catalyst for development of wastewater
reclamation, recycling and reuse. Aleppo clay showed (Clay cheap
material) good efficiency in the removal of surface-active substances
and the total dissolved solids and the remnants of oil and grease from
water, without the need for expensive equipment or adding chemicals,
this means low economic cost.
