Wastewater Treatment

C.L.E.A.N. provides cost-effective and safe wastewater treatment services with a wide range of aqueous treatment technologies for liquid/semi-liquid hazardous and non-hazardous waste in drum/tote and bulk forms. Along with our authorized service facilities we operate numerous processing sites with similar and varying capabilities to ensure a customer’s production line is never interrupted and that our treatment systems are always available.

Wastewater Treatment Technologies Include:
  • Chemical oxidation and reduction
  • Acid/Base neutralization
  • Flocculation
  • Filtration
  • Carbon adsorption
  • Supercritical fluid extraction
  • Chemical precipitation of metals
  • Biological treatment
  • Oil and water separation
  • Stabilization through encapsulation
C.L.E.A.N. and its authorized service facilities provide:

Network of company treatment sites – We operate multiple dedicated wastewater treatment and oil recovery facilities throughout Canada along with storage and disposal facilities offering unique reclamation and treatment capabilities.

Treatment of hazardous and non-hazardous aqueous waste – C.L.E.A.N. and its authorized service provider’s facilities are licensed and permitted to treat a wide variety of hazardous and nonhazardous wastewaters including:

  • Inorganic wastewater
  • Organic wastewater
  • Listed hazardous wastewater
  • Wastewater with heavy metals
  • Wastewater with organics
  • Non-hazardous wastewater
  • Oil and water mixtures
  • PCB wastewater

Treatment of inorganic aqueous waste – We utilize highly refined, multi-stage, chemical precipitation processes that remove heavy metals, suspended solids and residual organics from liquid waste that render the overflow safe for discharge into local municipal sewer systems.

  • Acid/Base neutralization
  • Chemical precipitation of metals
  • Chemical oxidation and reduction

Treatment of organic aqueous waste – Our facilities operate highly refined processes that remove heavy metals, suspended solids and organics from liquid wastes. Organic wastewater treatment methods include:

  • Chemical oxidation
  • Oil/Water separation
  • Supercritical fluid extraction
  • Biological treatment

Value-added transportation of drum and bulk waste by truck and rail – Through a highly coordinated and extensive transportation network, C.L.E.A.N. provides reliable, cost-effective transportation and waste disposal with a fleet of regular and super vacuum trucks that can handle any quantity of bulk volumes along with trucks/trailers that safely transport your drummed/toted waste to our state-of-the-art facilities. Transportation via rail is also available for transporting larger volumes of wastewater.

Why do we treat wastewater?

The most basic answer is to make dirty water clean. C.L.E.A.N.’s treatment facilities simply compress the organic decomposition processes which take place in nature and industrial production lines. This is performed by a combination of physical, biological and chemical treatment stages. Nature (receiving waters) can only accept small amounts of sewage before becoming polluted, that is, natural bacteria feed on the sewage organics and create an abnormal amount of dissolved oxygen uptake. Dissolved oxygen which exists in minute amounts (10 parts per million @ 20ºC), is required by all marine life for survival. One of the principle objectives of wastewater treatment is to prevent as much of this “oxygen-demanding” organic material as possible from entering the receiving water.

Other purposes of wastewater treatment include removal of objectionable items, nutrients and heavy metals.

Operations

Laboratory Analyses

Various wastewater samples are collected on a routine basis for analysis in our onsite laboratories. Approved methods are used to determine physical, chemical, and biological characteristics of the samples. Data generated is used for process control, report generation, and to ensure that our authorized service providers’ plants are meeting effluent restrictions as specified by the various regulatory agencies. A quality assurance/quality control program for all of our labs is administered by specialized lab analysts that help to ensure consistent and accurate results.

Training

We utilize a multitude of diverse technologies for our wastewater treatment facilities. Stringent regulatory guidelines increase the need for technologically advanced treatment facilities. As a result, constant training and upgrading is carried out, by both in-house and outside sources to ensure that personnel are able to keep pace with technology and operate our treatment facilities with maximum efficiency.

Safety

All supervisory and technical staff working in our wastewater treatment sections share responsibility in providing a safe work environment, for themselves, fellow plant personnel, and for visitors to our facilities. Each treatment facility is equipped with all necessary safety equipment and supplies. Copies of the Occupational Health and Safety Acts, facility specific policy and procedures manuals, personnel protective equipment manuals, Occupational Health and Safety First Aid Regulations, as well as many other safety standards are on hand at each treatment facility. Our plant personnel are committed to ensuring a safe work environment and participate, on a regular basis, in training for: Confined Space Entry, First Aid/ CPR, Transportation of Dangerous Goods, WHMIS and much more.

Managed Maintenance

As with any industry, unexpected equipment failures and shutdowns can be costly, with an adverse affect on the effluent quality of a facility. To avoid such situations we utilize a comprehensive preventative/predictive maintenance program. This program is comprised of routine service schedules and high tech computer systems. Vibration analysis technology utilizing a software interface assists staff in assessing potential equipment problems.
