Product catalog summary

Introduction
Orenco Systems offers Recirculating Sand Filters (RSFs) as an advanced, cost-effective solution for wastewater treatment. These systems are designed to be simple to construct using local materials and can be expanded as needed, making them a flexible option for various applications.

Specifications and Features

RSFs can handle wastewater treatment for applications ranging from single-family residences to large effluent sewer systems.
They consistently achieve effluent quality with BOD and TSS levels less than 10 mg/L and reduce total nitrogen by 40-50%.
Effluent can be used for subsurface disposal or, if allowed, disinfected for reuse or surface discharge.

Operational Advantages

RSFs require low power and minimal operator intervention, reducing operational costs.
They provide consistent effluent quality, making them suitable for irrigation or water reuse.
Orenco offers complete pre-assembled equipment packages, ensuring reliability and ease of installation.

System Components

Recirculation Tank: Primary treated wastewater is mixed and treated biochemically before being pumped to the sand filter bed.
Sand Filter Bed: Wastewater percolates through sand, where contaminants are broken down by microorganisms.
Control Panel: Includes remote telemetry for monitoring and controlling system functions.
Pumping System: Features Biotube® Pump Vault for protecting components and ensuring efficient microdosing.
Distributing Valve Assembly: Directs flow for sequential dosing without electricity.

Case Studies

Elkton, Oregon: Since 1990, an RSF has treated 30,000 gallons per day, maintaining low BOD and TSS levels.
Woodburn Mobile Home and RV Park: The RSF treats 10,000 gallons per day, with a focus on protecting local water bodies.

Company Background
