Tomato Cannery

A tomato cannery needed additional treatment to remove suspended solids from their process wastewater. At Heron Innovators, we specialize in the design, development, fabrication, and installation of highly efficient SAF® systems. A pilot trailer was placed at the plant and ran for two months during the 2012 processing season, proving the system’s capabilities and setting the stage for the customer’s order for a complete system to be installed.

The F100 SAF® Generator and CF1000 Clear-floater system has the capacity to treat the entire wastewater flow of up to 2,000 gpm, and consists of two 15-HP system feed pumps, a 5,000-gal. conditioning tank with recirculation / mixing pump, a polymer dilution and aging system, and control panels including a PLC for process control functions. It is custom fabricated from AISI 304 stainless steel, PVC and polyurethane. Our production planning allowed for a 14-week expedited turnaround time.

The site discharges its wastewater effluent for land application to a nearby farm. The entire operation is located near a growing urban area and odor complaints from the farm have been an issue during previous operating seasons. The treated water now resolves those issues by removing suspended solids and associated BOD. The water percolates more dependably into receiving soils reducing loading and quantities of stagnant water (greatly reducing odors from the site).

This cost effective SAF® system improves solid handling in the wastewater treatment process and operates automatically, requiring no continuous operator attention. Additional project details are listed below. For more information, contact us directly.

Case Study of a SAF® System For The Fruit Processing Industry

Heron Innovators installed the F50 SAF® Generator and CF250 ClearFloater treatment system for a California food processing facility. They contacted Heron Innovators for a system to be used for wastewater pretreatment. At Heron Innovators, we build mechanically and electrically reliable systems, and provide installation support which comprehensively meets our customer’s operational needs. The system is ideal for food processing wastewater pretreatment for reducing TSS and BOD/COD in discharges to sewers.

Designed for efficient particle and liquid separation, the system is made of 304 stainless steel, PVC, and polyurethane. It features a 3,500 gallon stainless steel conditioning tank measuring 8 feet in diameter and 10 feet in height, a Model CF250 ClearFloater™ flotation tank, a Model F50 SAF® generator, and a Model DWC3012 dewatering conveyor. The SAF® system is designed to achieve efficient flotation of solids in wastewater, and was delivered within a 16-week turnaround time, including installation. It operates on a simple automatic startup and shutdown control sequence. Full project details, including system unit dimensions, are listed below. Contact Heron Innovators to learn more.
