Expansion of the Shoket sewage works

Purpose

Expansion of the Shoket sewage works to give a flow rate of 30,000 m3 per day at a tertiary quality

The challenge

Working at an active sewage works without impairing its functioning requires precision planning.

Our part in the project management

Planning and supporting the construction of a sewage works with activated sludge technology for providing a 30,000 m3 per day flow rate and a follow-on project. The process includes pretreatment of waste water with filtration at two degrees and removal of sand, followed by treatment by activated sludge using 3 reactors with 2 final precipitation basins. The secondary treated water is run to a tertiary treatment array, which includes sand filtering and disinfecting by chlorination, followed by running by gravity to a nearby treated water reservoir and from it for recovery for agricultural use. The sludge is treated at the works by thickening on a gravity belt, long-term aerobic stabilization and final filtering using belt filters.
DHV has also planned peripheral auxiliary systems including a complex double pumping station that has multiple levels for the two main sewage lines and air treatment and odor neutralization systems.
