of water

Industrial operations periodically or occasionally generate wastewater, which is not compatible with their treatment facilities and discharge standards. This is specifically the case for effluent from chemical cleaning, which is likely to be collected into temporary storage tank and sent offsite for disposal. Tons of water are carried by road (with all risks and costs associated) even though a minimal quantity of contaminants or hazardous compounds must be dealt with.

The perfect combination of technology and cost-effectiveness


As a generator of this kind of wastewater, due to its industrial chemical cleaning activities, CTP environnement offers an alternative: mobile treatment units, which allow aqueous waste to be pre-treated or concentrated on site. As a direct consequence for customer, the overall costs of transporting and disposal are significantly reduced.

Initially designed to treat effluent from cleaning operations, mobile treatment unit scope also includes special aqueous industrial waste, toxic waste, production residues and leachates.

Depending on the nature of pollutant and their concentrations, they can also be adapted to clean tanks and pools or drain processes, etc.

Highlight on Clearflow® units


Modular, compact and automated, Clearflow® Mobile Treatment Units combine chemical preparation / injection and lamellar settling units, which can maintain an operating flow of up to 70 m3/h (308 gpm)

They can be deployed very quickly to separate suspended solids and hydrocarbons, precipitate metals and salts and remove sulphides, cyanides, phenols and hard organic compounds.

Treatment of effluent generated by cleaning the condenser at a nuclear power plant

Removal of metals using a physico-chemical Clearflow® mobile treatment unit

Steam condensers in nuclear power plants are made up of several smaller condensers, which themselves comprise approximately 21,000 metal tubes circulating cooling water. Due to the hardness of water drawn from the natural environment, the cooling tubes are subject to regular and significant scaling and need to be cleaned using ultra-high-pressure water jets (UHP).

REUSE of stripping effluents from nuclear power plant

Treatment of stripping effluent from a boiler structure in preparation for a surface coating renovation application

CTP environnement set up a treatment solution that provided the customer with several reuse options:

  • Recycling on an ultra-high pressure stripping unit with the following water quality constraints:
    T° < 30°C, pH 6-8, TSS < 5 ppm, COD < 20 ppm, metals < 5 ppm, conductivity < 1000 µS/cm2
  • Refrigeration of pre-treated water
  • Washing and rinsing water
