Title : Treatment of Domestic Wastewater Using a Novel Compact Unit


The aim of this work is to examine the new design of a compact unit. The compact unit consists of three consecutive treatment steps. The primary treatment step is vertical settler (VS) followed by the self-aerated chamber (SAC) (secondary treatment). The dimensions of the compact unit are 1*2*2 m for length, width, and height, respectively. The dimension of the vertical settler is 1.25*1*2 m for length, width, and height, respectively. The detention time (DT) was kept constant at 5 hr in the vertical settler chamber. The compact unit was packed with a non-woven fabric material produced from waste plastic bottles. The influent organic concentrations expressed by chemical and biological oxygen demand (COD and BOD) were 367.7 and 254.7 mg/L, respectively. The organic concentrations (COD and BOD) in the final treated effluent were reduced by 78.8 and 80.5% to 36.7 and 16.6 mg/L, respectively. With the exception of fecal coliform (FC), the final treated effluent is complying with the National Regulatory Standards. The area required for this unit is only 2 m2. This makes such a compact unit attractive to apply in rural and unserved areas in developing countries.

Audience take away:

  • The audience will be able to deal with the dangers of the discharge of untreated wastewater.
  • Attendees will be able to understand the role of integrated treatment plants for development in rural and unserved areas.
  • The audience will understand how to valorize the waste plastic bottles.


Prof Dr. Mohamed El-Khateeb studied Chemistry at the Helwan University, Cairo, and graduated with an MS in 1993. He then joined the National Research Centre, Water Pollution Research Department, Environmental Chemistry. He received his Ph.D. degree in 2005 at Cairo University. He joined several projects (National and International). His work is focusing on wastewater treatment and pollution prevention. He is EIA certified consultant. He was awarded 3 patents. The patents are concerned with the treatment of water and wastewater using compact units.
