Swine Treatment System

Hoffland Environmental, Inc. has developed a new economical process to treat waste produced by large-scale confinement of animals. The new process uses efficient methods to remove the entrained solids followed by aerobic biological oxidation of the clarifier liquid. The process is essentially odor free and excess nitrogen is biologically removed. The odor free treated water is used for automatic flushing of the confinement areas and for building wash down. Additional wash water is not required.

Biological Treatment

Hoffland Environmental manufactures custom designed biological treatment systems to remove organic contamination from wastewater. In the case of sanitary waste, HEI manufactures a complete line of package treatment plants varying from 1000 gallons per day to 500,000 gallons per day. Units up to 50,000 gallons per day are shipped as factory assembled modular units. Units over 100,000 gallons per day are usually assembled on site. Tertiary filters are included when the discharge limitations are very stringent.For industrial wastewater containing high levels of soluble organic products, it is usually more economical for the generator to pre-treat the wastewater, reducing the COD level to less than 500 and significantly reducing the city imposed surcharge. HEI customizes its system for each particular customer.
