Wastewater Treatment Projects

Department of Works, Aruba

The Department of Works Aruba (DOW) issued an international tender in April, 2005 for the design and construction of two new SBR wastewater treatment plants (at Parkietenbos and San Nicolas) and the expansion of a third plant (Bubali) on the island of Aruba.  The tender attracted bidders from Europe, Mexico, and the United States.  Florida Aquastore partnered with a prominent Aruban contractor who supplied the civil works (buildings, roads, concrete structures).  Florida Aquastore was responsible for the process and mechanical design, supply and installation of all mechanical equipment, piping, and treatment tanks.  The Florida Aquastore team was the low bidder and was awarded the contract in July, 2005.

Today, all three treatment plants are on line, treating 100% of Aruba’s wastewater, and performing to Aruba government’s rigid specifications. The fully automated and advanced treatment plant designed and constructed by Florida Aquastore enables a large portion of the wastewater to be re-used for internal plant use and irrigation.  This helps the government conserve a valuable commodity and save operational costs.

Bubali Extended Aeration Plant

The Bubali scope of work included renovating and expanding an existing extended aeration (Oxidation Ditch) WWTP.  The old flow rate was 600 m3/h.  The plant was expanded by 710 m3/h (more than doubling the existing capacity).

Parkietenbos Septic Wastewater SBR Plant

The Parkietenbos is a NEW plant designed to handle septic wastewater hauled in from vac-trucks.  The Sequence Batch Reactor plant was designed for a flow rate of 275 m3/h.  This plant included sludge dewatering system to handle sludge trucked in from all three plants.  Influent BOD is 1,347 kg/d, TSS is 2,695 kg/d. Effluent requirements were less than 10 mg/l BOD and TSS.

Zeewijk SBR Plant

The Zeewijk plant is a NEW plant designed to handle typical domestic wastewater coming from a nearby town.  A Sequence Batch Reactor was designed to handle 430 m3/h flow rate.  Influent BOD and TSS was 300 mg/l.  Final effluent requirement was less than 10 mg/l BOD and TSS.
