EXTENSION OF THE PAFOS SEWAGE TREATMENT PLANT AND PUMPING STATIONS

Challenge

Wastewater treatment projects are always challenging, but when upgrading of existing works is involved the challenge increases.

The project included:

  • Upgrade and expanding the existing screening facilities, primary treatment, secondary treatment (bioreactors, secondary clarifiers, pumping stations), tertiary treatment (filtration phosphorous removal), emergency storage lagoons, service networks etc and the construction of new facilities (abolishment of existing facilities) for septage reception and treatment and grease and grit removal and treatment unit.
  • Upgrade and expanding the existing sludge treatment works and the construction of new facilities for the anaerobic digestion of the primary sludge with capacity 3500 Κg DS/d (Phase ΙΙΙ) consisting of a digestion tank, a digested sludge storage tank, a digested sludge dewatering unit, a gas-holder tank, a cogeneration unit and a gas flare, etc, and a solar sludge drying plant for the total sludge produced of 5000 Kg DS/d (Phase ΙΙ).

Approach

The services provided include the Technical study at the Tendering Procedure (FIDIC Conditions for Design - Build) and the preparation of the Detailed Engineering Design leading to the construction of the works.

  • Hydraulic, Electromechanical and Process Engineering design leading to the construction of the plant.
  • Support the Client in the selection of the Electro-mechanical equipment
  • Operation control and optimization of existing facilities.
  • Support the Client in the start-up operation and the plant commission procedures

EMVIS with its extensive experience coordinated and successfully completed this demanding project with increased responsibility in order to ensure that the mission and the objectives have been met on-time with the highest quality standards.

Impact

Uncollected and untreated wastewater is a major source of pollution that affects quality of fresh and marine waters and presents a risk to human health and biodiversity. The positive impact of wastewater infrastructure projects is widely acknowledged with main objective to protect the environment from the adverse effects of urban waste water discharges.

Challenge

Water information is highly sought after by many kinds of end-users, both within government and business as well as within civil society. Water touches virtually all societal and environmental domains and the knowledge domain is largely multidisciplinary.

Tools

wPOLIS

wPOLIS

wPOLIS is an interactive web map tool for calculating the temporal and spatial variation of Emission Limit Values for specified pollutants in a River Basin and also for defining exclusion zones where installation of new facilities is restricted due to water quality or other environmental criteria.

wHYDE

wHYDE

wHYDE is a tool which supports the design of free surface sewer and storm water networks. wHYDE has been developed as an add-on to the familiar working environments of Autodesk AutoCAD and Microsoft Excel, it is easy to use and boosts productivity.
