PROJECTS TYPE

Systems solutions provided by PNW include a wide range of water and wastewater projects. Our engineering team is specialized, but are not limited to, in various and difficult projects such as the ones referenced below.

Municipal Wastewater Treatment


Improve existing treatment in facultative lagoons and create high efficiency treatment in new facilities. Reduction of CBOD, TSS, organic sludge, ammonia and odor.

Industrial Water and Wastewater Ponds



Wastewater process assessment and evaluation to determine type of treatment and equipment required. Treatment of process wastewater, storm-water runoff, odor control, and improved cooling pond performance.

Lakes health manage-ment



Increasing oxygen levels and improving circulation mitigate using aeration results in algae reduction, odor control and prevents winter fish kill due to oxygen deficiency.

Agricultural Wastewater Lagoons



Odor control with aeration or with a floating cover system. Secondary manure treatment system for effluent water reuse.
Raw Water Reservoirs



Increasing oxygen levels through aeration to eliminate taste & odor, reduce organic, iron and manganese concentrations, eliminate thermal stratification, and generally improve water quality.
Grease control




Odor control and grease accumulation are typical problems associated with sewage force mains. An engineered bacteria injection system reduce H2S production, and associated odors and corrosion.
Wastewater tanks management



The use of a pond cover system for airside retention ponds is an effective method of reducing airport waterfowl. Airport stormwater runoff and snow-melt can effectively be treated in aerated basins.
Sewer corrosion




Oil and grease in the wastewater cause trouble in the collection system pipes. It decreases pipe capacity. Oil and grease also hamper effective treatment at the wastewater treatment plant.
Copper & lead leaching



Cooper and lead leaching are the result of the corrosion in tanks, pipes (...) due to unbalanced pH. Aeration and Ozone combined has been proven to be one of the most cost-effective solution.
Private & Golf Course ponds



Pond optimization through aeration and bacterial augmentation results in a “healthy” or balanced aquatic ecosystem can reduce nuisance problems such as algae, mosquitoes, stagnant water, and eliminate odors.
Ice Melting / Control




An engineered aeration system effectively reduces ice thickness and potential hull damage for boats and other marine equipment wintered in ice conditions. Frazzle ice accumulation around river intakes can be minimized. Ice-melting is an effective approach to increasing winter storage capacity in raw water storage and sewage pond systems.
