Industrial wastewater recycling installation

Based on its range of industrial wastewater treatment plants, but also on its air flotation water treatment plants, NISKAE implements global installations for the recycling and reuse of treated industrial water.

The reuse of treated water (REUT or REUSE) is used in many countries and is one of the most effective ways of dealing with water stress. Find out how Niskae enables industrial wastewater to be reused as washing water.

Industrial wastewater recycling and reuse unit: how does it work ?

The first step is to collect wastewater and washing effluent. Our industrial water recycling systems collect cleaning water by setting up one or more pumping stations in your workshops. A piping network sized according to the constraints of the building will convey the washing water to a wastewater storage tank.

Our wastewater tanks have capacities from 500L to 40,000L and are equipped to ensure homogeneous mixing of water, correct water pH and prevent bacterial growth by oxygenation or the addition of antibacterial reagents.

Clear water storage tanks

Treatment by coagulation and flocculation in the treatment reactor produces a clear water phase and a sludge phase. After filtration through a filter box or filter press, the clear water is separated from the treatment sludge and collected in a storage tank. NISKAE offers clear water storage capacities ranging from 500 to 40,000L.

Stored clear water is oxygenated and maintained in permanent recirculation. Several filtration devices can be added to guarantee precise water quality for the industrial process concerned. Whether it’s a sand filter, an activated carbon filter or a set of filter cartridges, NISKAE integrates all these filtration technologies as standard.
The addition of an osmosis unit may also be necessary in the case of a specific water quality requirement, such as food grade.
NISKAE clear water tanks also offer temperature control of the reused treated water by means of submerged heating resistors.

Clear water reinjected in the rinsing cycle

Clear water from the recycling process is re-injected into the rinsing circuit by a booster pump equipped with a filtration station.

Water levels in the system are constantly monitored to maintain a stable and sufficient volume of circulating water. If necessary, water is to be topped up and controlled by the system.

Flow rate, pH, conductivity and temperature parameters are continuously measured and recorded to ensure strict monitoring of recycled water quality and consumption.

Recycling station control panel

The electric control panel integrated to our industrial wastewater treatment and recycling The range of water treatment and recycling plants designed by Niskae includes a range of fully standardized electrical control panels.

NISKAE designs and assembles its own range of control panels integrating a PLC and a touch screen for easy access to data and functions of the water treatment plant.

The operating program for our units is developed by NISKAE’s programming engineers to meet the specific needs of water treatment processes.

Our electrical control panels are fully pre-equipped, enabling our customers to upgrade their water treatment plant in the medium or long term by adding the hardware options offered by NISKAE.
In this way, all NISKAE customers are able to upgrade their plants to REUSE and recycle 100% of their treated water.

Since January 2023, and the implementation of its own VPN solution, NISKAE has been able to offer a remote, real-time monitoring service for all its water treatment and recycling plants. Our Montreal-based monitoring center will be able to carry out a preliminary diagnosis before any intervention.

Our customers and users are also able to track the operation of their water treatment equipment by logging on to their online logbook. Operating data and water parameter measurements are recorded, stored and accessible at all times.
