California corn processor reveals $158,000 annual hauling cost savings

Find out how with an expert consultation.


A California-based corn processor had an inefficient wastewater treatment line, and was paying $250,000 each year in hauling costs to dispose of high-moisture sludge from their treatment process.

The plant’s on-site treatment system used twelve 10,000 gallon (30,000 L) settling tanks and a large treatment lagoon for sediment capture; each day the plant was drawing 6,000 gallons (22,000 L) of sludge from the bottom of two of these settling tanks and then trasporting it by truck to a local wastewater treatment plant for disposal.

The business understood that they needed a better long-term solution than this expensive workaround.


The plant owner identified the Hydro-Industrial MicroScreen™ as a viable alternative system, and scheduled a trial.

The unit was tested under real-world conditions on typical daily flows to determine how much it could improve their operation and reduce their operating costs.

Effluent samples were sent to an independent laboratory for analysis. 


Independent laboratory analysis revealed that the Hydro-Industrial MicroScreen™ removed 66% of the particulate BOD in the plant's wastewater.

Analysis of the results indicated that installing a single Hydro-Industrial MicroScreen™ system at this plant would save the facility $158,000 in hauling costs alone every year.
