Preserving a town’s natural resources with an all-terrain sewer

An All-Terrain Sewer is constructed of PVC pipe with solvent-welded joints and leak tested to the same standards used for potable water supply piping networks. Water-tight and virtually leak-free, it is not subject to infiltration from groundwater or from surface stormwater entering through leaking pipe joints and manholes.

OOWA has developed several resources that are directed to rural property owners, encouraging them to regularly maintain their onsite sewage systems to ensure their longevity and the protection of human health, lifestyle, and the enjoyment of water resources.
Installed prefabricated lift station

Prefabricated stations address wastewater challenges for remote communities

Wastewater pump stations designed for small communities are the heart and arguably the most important component of a decentralized treatment system. They can be assembled on-site by pouring concrete and then adding each required component, or can be pre-assembled (pre-fabricated) before arriving on-site, which significantly reduces project complexity, cost, and the time required for installation.
Pilot Butte wastewater treatment lagoons

Working together with Nexom’s Winnipeg-based lagoon process team, the project engineers designed a solution that would enable Pilot Butte to maximize the use of their existing lagoon infrastructure without sacrificing the operation and maintenance simplicity, to meet additional capacity and more stringent effluent limits.
Flygt adaptive mixer

What can you do with adaptive wastewater mixers?

Wastewater treatment plant operators are increasingly turning to mixers with integrated variable speed control, which can dramatically lower energy use and reduce wear. With a growing focus on nutrient removal, energy management and optimization, mixers present an extraordinary opportunity for improvement for most wastewater treatment facilities.
Fuzzy Filters

Fibre balls in the fight against micropollutants

Fuzzy Filters, which are made from synthetic fibres and shaped into a sphere, are said to be able to eliminate as much as 95% of all trace substances and also remove microplastics and phosphorus from wastewater. Unlike conventional filter systems, the liquid to be filtered flows both around the outside of the filter material as well as through it.
Fat Oil and Grease

Understanding the impacts of FOG on wastewater systems

Removal of FOG in the production stage can prevent the need to treat downstream. In some cases, a gravity grease interceptor can be used to remove FOG prior to additional treatment or discharge. Source grease traps identify and treat for FOG at specific high FOG areas and remove them before they make it to the waste stream.

Hydrothermal liquefaction (HTL) is a biomass processing technology that has recently become prominent in the wastewater treatment field. It could address a number of the issues regarding sludge management in wastewater treatment plants. HTL is a thermochemical biomass conversion method that mimics the natural formation of petroleum converted from dead biomass under high temperature and high pressure, which takes millions of years.

ClariPhos UVT Chart

Using a phosphorus coagulant can improve wastewater UV disinfection performance

After switching to ClariPhos™ rare earth coagulant to evaluate its ability to improve phosphorus removal, operators at an Ontario WWTP noticed that UV disinfection also experienced a big boost. It turns out that better settling in the clarifier led to higher UV transmittance in the effluent, and a significant improvement in UV disinfection.

Cleaning industrial wastewater collection systems requires specialized equipment

The task of industrial pipe cleaning typically falls to third party cleaning companies, who come to facilities with a vacuum truck and perform the work periodically, unless emergency debris removal is required. Industrial plants cannot afford production downtime, so contractors rely on high-performance nozzles to get the job done quickly and reliably. Using the right nozzle and technique can be the difference between cleaning out a pipe within 20 minutes or having it take hours, days, or even fail completely.

Pumping long chain polymers in wastewater applications without damaging them

Flocculant and coagulation polymers are used in the removal of solid particles. Flocculants separate solid content in the wastewater from the liquid content. A coagulant combines small particles to form larger chain particles. These polymers change the charge of the particles, so that they will combine rather than repel other particles.
