Maui Cattle Company
Industrial Wastewater Treatment and Reuse using Natural Systems
The Maui Cattle Company is developing a new meat-processing facility on the island of Maui, Hawaii. The facility is located near a residential area and the client desired a wastewater treatment and reuse system that minimizes odor, provides reuse-quality treatment in an environmentally-sensitive manner and supplies reclaimed effluent for pasture irrigation.
The treatment facility produces reuse-quality effluent from up to 14,000 gpd of high-strength wash-down water from the plant. Treatment components include prescreening and a dissolved-air flotation (DAF) unit, roughing and nitrification trickling filters, subsurface flow constructed wetlands, a recirculating sand filter, mechanical filtration, and UV disinfection. Reclaimed effluent is stored in an onsite, covered irrigation pond. Approximately five acres of pasture land is irrigated with the effluent, drastically reducing the facility’s water consumption.
Natural Systems International integrated conventional pretreatment technologies (screens and DAF) with treatment components based upon natural processes (wetlands, sand filter, trickling filters) to handle industrial-strength effluent in a mechanically simple and energy efficient process.
