Wastewater Treatment Systems

CHALLENGE: Collect wastewater from showers and lavatories, treat it to a quality suitable for reuse and put it back into a separate water system furnishing flush valves in the lavatories. Estimated use by the flush valves is 250 to 300 gallons per day.

This unit is certified to NSF350 for water reuse. A 500 gpd unit is being provided in a tank with 3 compartments. At 250 gallons per day, the clinic can save over 90,000 gallons per year of fresh water.

This industrial facility is located outside of Hillsboro Missouri on a hillside that is cut from a rock bluff. The site provides no soil for an on-site system for a facility with around 80 full time employees. Previously, the facility utilized pump and haul for sewage disposal and trucks would need to access and pump out the tanks frequently.

A permitted discharge system was designed that could meet NPDES permit requirements of the EPA.

A BioMicrobics HSMBR1.5 unit services the facility with waste consisting of a bathroom and water from the cleaning and repair processes. Because the stream that receives the discharge is a small tributary to the Big River, very low limits of contaminants were placed on the facility.

The facility is regularly tested at undetectable BOD and TSS and < 0.5 mg/l ammonia nitrogen. This quality is well under the limits imposed for permit. The facility discharges between 600 gpd and 1200 gpd 5-6 days per week.

Malibu point is a development of six homes on Horseshoe Bend at the Lake of the Ozarks.

A discharge system for sewage disposal was required. The BioBarrier 3.0 was installed to serve the six large homes because it basically eliminates all BOD and TSS from the discharge along with reducing ammonia nitrogen to under 0.5 mg/l. Viruses and organisms are contained within the tank eliminating the need for disinfection of the discharge.

The entire system consists of individual STEP systems pumping to a two-chamber collection tank with the second compartment containing a Sanitee filter to remove any solids that could harm the membrane system. Flow from this tank then goes to the treatment zone and then discharged.
