Once the wastewater from your project site has been collected, it needs to be treated in order for it to be deemed clean enough to release back into the environment. The goal of treatment is to treat and discharge the clean water while maintaining the capacity you require for growth while staying in compliance with permitting.

There are numerous challenges in meeting these demands. Costs rise constantly. Regulations change. Equipment ages and needs to be replaced. Shortages of staff and budget cuts round out the more common problems.

Our team of scientists, engineers, equipment operators, and consultants will help you make informed decisions regarding your wastewater treatment project. All of our recommendations will be in line with keeping your project not only within budget but with maximized returns.

Designing the Project Requirements

The first thing that will need to be scheduled is a project needs assessment which will then give us the preliminary engineering reports necessary to design your wastewater treatment program.

We will bring in all operational consulting personnel needed, and within the confines of permitting and reporting requirements, hand you a custom design for your program. Close attention will be paid to your discharge limits and sludge disposal.

The Process of Wastewater Treatment

At the most basic level, wastewater treatment is the separation of water from solid contaminants through a process known as sedimentation. There are numerous steps to accomplishing this:

  • Phase Separation occurs in different points of a treatment sequence. While it is an important part of initial treatment, it is perhaps more important later on when various impurities are actually the result of the treatment process. Disposal options vary as to the type of impurities removed.
  • Sedimentation is a process where gravity is incorporated to remove suspended solids from the water. There is a very specific relationship between the rate at which the particulates settle and the diameter of them. The velocity of the water flow is carefully monitored to ensure that all contaminants are removed leaving the water clean enough to be released back into the environment.
  • Filtration takes place through the use of physical barriers, screens, and sieves that take any particulate matter out of the water.
  • Oxidation will reduce the toxicity of many impurities. It also reduces the demands of biochemical oxygen by the wastewater. Chemical oxidation is commonly used for disinfecting the water. Biochemical oxidation and chemical oxidation are two separate subprocesses of the oxidation process.
  • After sedimentation, filtration, and oxidation have taken place, the next step is called polishing. The polishing treatments can also be done independently for certain industrial wastewaters. Using chemicals, the pH level is adjusted to minimize any chemical reactivity of the wastewater following the oxidation process. Finally, carbon filtering removes any other contaminants and impurities. The leftover solids from all these processes are referred to as sludge.

Wastewater treatment can involve the construction of holding ponds and tanks. Once we know the composition of the contaminants, the removal of the sludge can be arranged.
