Municipal wastewater treatment pond

Introduction

Demands on water resources for municipal development continue to increase throughout the United States. It's why many existing wastewater treatment lagoons currently in operation that do not consistently meet their treatment objectives. In order to meet these demands, PNW propose different solutions. Methods of dealing with municipal wastewater in both new and existing facilities vary significantly and may include:

  Upgrading passive or facultative systems to aerated systems within existing infrastructure
  Converting deep anaerobic cells to primary complete mix cells
  Replacing existing aeration equipment with new high-efficiency aeration
  Designing systems that allow for future expansion of a growing community
  Operational cost savings realized through exceptional oxygen transfer efficiency
  Supplementing existing wastewater systems, both lagoon-based and mechanical plants
  Constructing new lagoon-based systems where both capital and operational costs are typically lower than mechanical systems Each wastewater treatment system is unique.

Typical issues with both new and existing systems may include:

CBOD5 Reduction Fine Bubble Aeration technology combined with exceptional oxygen transfer provides optimum BOD reduction in both new and existing municipal wastewater lagoons.	TSS Removal Fine bubble aeration provides high dissolved oxygen and mixing with minimal turbulence to facilitate suspended solids removal up to 93%.
Organic Sludge Reduction Organic Sludge accumulation is significantly reduced with a combination of fine bubble aeration and Bacta-Pur® bioaugmentation without producing odors.	Algae control Algae formation can be a real problem in installation containing filters and such equipement.
Ammonia Reduction Ammonia reduction in a series of aeration ponds with bioaugmentation (beneficial bacteria) and biofiltration systems (Aquamats®) ranges between 60 and 95%.	Odor Control From aeration to Armor Balls™ cover system, PNW provides many Odor-free treatment adapted to your needs. Odors resulting from spring turnover and H2S production are limited.
