OMPAPATM - One Moving Part Plant
OMPAPATM ADVANTAGES
Compared to the current standard for new small-scale and intermediate scale waste water treatment plants:
-
lower capital cost (up to 40% lower),
-
lower operations and maintenance (O&M) cost (average 50% lower),
-
smaller foot print (typically 35% smaller)
-
less time to construct and start-up (typically 35% less time)
OMPAPATM - MEDIUM TO LARGE SCALE WWTP’S
The patented OM-PA-PATM (One Moving PArt PlAnt) technology represents a major breakthrough in the safe, reliable, environmental treatment of wastewater and sewage for towns, developments, and cities for the 21st century. The process consists of just one tank driven hydraulically. There are no ancillary sub-systems and associated pumps, no clarifier drive or traverse bridges. The foot print for the Om-Pa-PaTM plant is significantly less than the size of a conventional plant with equivalent capacity through the elimination of unnecessary subsystems. The plant achieves significant energy savings (up to 60%) since the entire plant operates using one fluid pump.
Because of the complete mix flow pattern in the aeration basin, there are no dead zones. This means that accurate control of the DO can be achieved easily in the Om-Pa-Pa in two ways; either through use of a variable drive pump in which more air is aspirated as the flow rate in increased, or by use of a valve on the pump that achieves the same effect

OMPAPA AERATION FLOW PATTERN
IN CONCENTRIC AERATION & CLARIFIER BASIN DESIGN
Oxygen Transfer Efficiency >28% without membranes or acid cleaning is achieved through a synergy of the basin flow pattern and the mechanical dispersion of very fine bubbles. The air is aspirated into very fine bubbles in the in fluent and the inlet flow is directed in a torroidal pattern down the wall of the aeration basin across the bottom, up the center of the tank, and then radially outward back to the walls. Surface aeration (entrainment of air into the water) is also achieved and the flow pattern optimizes the transfer efficiency.
Clarification with multiple take offs eliminate short circuiting, allowing variable sludge age independent of detention times, sludge return rates, surface overflow rates, insuring effluent quality over a wide range of flows; eliminating the need for external pumps or mechanical clarifier drives.
