Nutrigest: A Powerful Tool for Environmental and Water Treatment
Nutrigest is a proprietary technology developed by Smith & Loveless, Inc. for the efficient treatment of wastewater. It's a unique, high-rate, submerged biological process specifically designed to remove nitrogen from wastewater. Nutrigest is most commonly used in conjunction with clarifiers, which are vital components in wastewater treatment plants.
Clarifiers are large, circular or rectangular tanks that are used to separate solids from liquids. In the context of wastewater treatment, clarifiers remove suspended solids like sludge and grit, facilitating a cleaner effluent. The clarifier's role in Nutrigest is crucial in removing the biomass produced by the nitrogen-removing bacteria in the process.
Here's a breakdown of Nutrigest and its integration with clarifiers:
Nutrigest:
- Function: Nutrigest utilizes specialized bacteria to convert ammonia (NH3) into nitrate (NO3-) and then into nitrogen gas (N2), effectively removing nitrogen from wastewater.
- Process: The wastewater flows through a series of tanks where the Nutrigest bacteria are housed. These bacteria require specific conditions (temperature, oxygen levels, etc.) to thrive and efficiently remove nitrogen.
- Benefits: This technology provides a highly effective and cost-efficient solution for wastewater treatment, especially in managing nitrogen pollution.
Clarifiers in Nutrigest:
- Function: After the Nutrigest process, the wastewater is sent to the clarifier to remove the biomass generated by the Nutrigest bacteria.
- Mechanism: The clarifier uses gravity or mechanical means to separate the solids (biomass) from the treated wastewater.
- Types: Smith & Loveless offers a range of clarifiers, including circular, rectangular, and lamella clarifiers, each suited for specific applications and flow rates.
The Nutrigest-Clarifier Synergy:
The combination of Nutrigest and clarifiers creates a robust and efficient wastewater treatment system. Nutrigest effectively removes nitrogen, while the clarifier ensures the removal of the biomass produced by the Nutrigest bacteria. This synergy ensures a clean and safe effluent discharge, contributing to environmental protection and water resource sustainability.
