Historically, wastewater management is a matter of caring for our environment and health. Due to global water shortages and scarcities, the world is looking into new ways to preserve our most valuable resource – water. These scarcities have shed light on wastewater as an unconventional, yet valuable, water resource.
With an emphasis on employing circular economy and resource recovery, Delco Water is creating the groundwork in promoting innovative treatment technologies and management strategies in wastewater-related areas. Our advanced and efficient wastewater treatment technologies offer the highest-quality effluent while meeting the most stringent environmental standards. These technologies are specifically designed considering different urban, rural, and indigenous communities’ needs across Canada. Delco Water has been enthusiastically following new approaches regarding wastewater optimization and minimum to zero liquid discharge strategies.
What is Wastewater Treatment?
Wastewater treatment is a process used to remove contaminants from wastewater and convert it into an effluent that can be returned to the water cycle. Once returned to the water cycle, the effluent creates an acceptable impact on the environment or is reused for various industrial, agricultural, and domestic purposes. Although there is a wide range of applicable technologies for treating different source of wastewater, the technologies most commonly used for performing main treatment stage (secondary treatment) of wastewater treatment plant rely on microorganisms suspended in the wastewater to treat it.
Primary treatment, which is often referred to as primary sedimentation, removes material that will either float or readily settle out by gravity. It includes the physical processes of sedimentation when gravitational forces allow for settleable and suspended solids to settle due to being heavier than water. Accumulated solids are removed and disposed, and primary treated wastewater continues to next treatment step.
Secondary treatment is the next step in the treatment process. Secondary wastewater treatment is a biological treatment process designed to reduce the number of organic materials in the wastewater before it is discharged to a disposal or sent to tertiary treatment and disinfection. Secondary treatment produces a much higher quality of effluent than a primary treatment. The process involves the removal of biodegradable organic matter, nutrients, and suspended solids (TSS) using aeration and clarification. Traditional secondary treatment is typically characterized as producing a treated wastewater effluent with a BOD of 25 mg/L or less and TSS of 30 mg/L or less.
Technology-oriented treatment methods to address our clients’ specific needs and produce the highest quality effluent.
Our main two wastewater treatment systems are the MBBR and MBR.
1. Membrane Bio Reactor (MBR)
Instead of conventional municipal and industrial treatment plants with high operational cost and large space requirements, our containerized membrane bioreactor provides a cost-efficient, high performance, portable system. With the high-tech membrane, this process offers zero scum or sludge discharge with the highest efficiency. The resulted quality effluent is a great source for reusing and recycling water.
2. Moving Bed Biofilm Reactor (MBBR)
Our MBBR, benefiting from the most advanced technologies, offers a high surface area bacteriological treatment process with low generated sludge footprint. Its cost and energy efficient process provides effective solutions for communities with domestic and industrial wastewater issues.
