Parkson Selected for Multi-Million Dollar Ogg Israel Project Expansion

Parkson is proud to announce our selection earlier this year for the Ogg Wastewater Treatment Plant expansion in Jerusalem, Israel. This multi-million dollar project includes the following Parkson equipment: Biolac® Long Sludge Age Treatment Process; Aqua Caiman® Articulating Rake Screen; Aqua Rhino™ Escalating Step Screen; Aqua WashPress® Dewatering Screw Press; and Hycor® Helicon® Spiral Conveyor. Additionally, Parkson supplied clarifiers, blowers, RAS pumps and a grit removal system as part of the package.

A great effort by many people across several departments went into nurturing this project. We thank you all for your hard work, dedication, and support in securing this order. Package systems are expected to start delivering in late 2021 through 2023. Parkson is thrilled about the partnership with Jerusalem Water Purification Enterprise (JWPE) and we look forward to a future relationship with the company. Below is a highlight of the project as it pertains to the Biolac treatment system.

Biolac® at Ogg Wastewater Treatment Plant

The Ogg Wastewater Treatment Plant is located east of the city of Jerusalem and treats municipal wastewater from the eastern side of the city, the Kidron Valley and the surrounding area. It is operated by Jerusalem Water Purification Enterprise (JWPE)), a Jerusalem Municipality owned company. Built in 2014, the plant design utilized in-ground earthen basins to treat the wastewater in a series of flow-through lagoons. With the diversion of the Kidron Valley wastewater to the Ogg Valley, it was recognized that the plant did not have sufficient capacity to treat all the wastewater from its service area and additional capacity was urgently needed. Either a new plant had to be built, or the existing plant had to be upgraded to significantly increase the treatment capacity – from 6.6 MGD to 24 MGD – and as soon as possible!

The Parkson Biolac® Long Sludge Age Treatment System proved to be the ideal upgrade for the Ogg WWTP. Rather than a flow-through lagoon process, the Biolac system uses a long sludge age, activated sludge process capable of treating 4-5 times the flow in the same treatment volume and producing reuse quality water for the city in a simple-to-operate system. Other treatment alternatives considered required the construction of new, concrete treatment tanks, while the Biolac was able to reuse the existing in-ground basins, repurposing them as new treatment tanks. When project costs, timing and operational requirements were all considered, Biolac was the clear choice for JWPE and the city. After visiting several existing Biolac installations, JWPE opted to include Parkson’s unique Wave-Ox™ Plus process upgrade which provides for total nitrogen removal in a single treatment basin, ensuring the effluent is suitable for agricultural reuse, which benefits the entire surrounding community.

The project not only delivers water for reuse, but the design also includes a hydroelectric turbine for power generation, taking advantage of the approximately 300m elevation drop from the wastewater source to the plant site. The power generated will be more than that required to operate the treatment plant with the additional power being returned to the grid to provide power to other users – a true zero carbon footprint project!

The Ogg WWTP is truly a beneficial project for the entire community, providing high-quality reuse water and power for years to come.
