Lagoon Effluent Reuse for Irrigation

Wastewater lagoons or ponds are widespread as a simple technology for wastewater treatment where sufficient area is available. Their large surface has the disadvantage that a great portion of the water is evaporated in hot and arid climate. Their treatment efficiency is limited, and removal of sludge is difficult and expensive.

Our OptiLagoon Solutions improve lagoon treatment efficiency and facilitates reuse of the effluent for irrigation, particularly for water saving drip-irrigation.

Our first improvement step is the addition of fine or micro-screens for wastewater pre-treatment. They prevent scum formation and clogging of drip-irrigation lines.

The next improvement step is filtration of the overflow from aerated lagoons with our rotating VRM membrane filters. The membranes retain all solids and bacteria, but nutrients remain in the effluent. The retained active biomass is returned to the aerated lagoons. We greatly increase their biomass concentration, their biological treatment efficiency and capacity.

Anaerobic, non-aerated, settlement and polishing lagoons are no longer needed and can be upgraded into aerated lagoons, further increasing treatment capacity and efficiency. Massive methane emission and breeding of disease carrying mosquitoes is prevented.

We upgrade lagoons to far more compact and efficient membrane bio-reactor (MBR) systems. In this way, we also reduce their surface and evaporation losses.
