Uncompromising treatment of industrial effluents

Maximum reduction of pollutants with a simple, reliable and eco-responsible process.

Reduction of polluting loads

The VAL INDUS process makes it possible to reduce up to 95% of the pollutants present in the effluents (DCO, MES, DB05) by up to 95%, thus ensuring discharges in accordance with strict environmental standards and minimizing risks for the environment.

Energy saving and cost reduction

The VAL INDUS system consumes up to three times less energy than traditional processes, while simplifying the management of consumables, thus offering an economical solution over the long term without sacrificing efficiency.

Valorization of sludge and optimization of space

Thanks to its vacuum flotation process, the VAL INDUS system makes it possible to concentrate solids, facilitating the valorization of sludge and reducing the land space required for wastewater treatment plants.

Positioning of VAL INDUS

Positioning

The VAL INDUS can be positioned at different levels in the industrial water cycle. It can be located upstream on filtration, in pre-treatment before sending to a wastewater treatment plant or in pre-membrane treatment.

Challenges specific to each industrial sector

Issues

The food industry

For the treatment of wastewater from food production, such as washing water, cooking water, etc.

The stationery

For the treatment of effluents loaded with organic and particulate matter, commonly encountered in the paper industry.

The textile

For the removal of dyes, chemical agents and particles suspended in wastewater from dyeing and washing processes.

Industrial laundries

For the treatment of wastewater rich in detergents and organic materials, guaranteeing a discharge in accordance with environmental standards.

The sugar industry

For the purification of condensed water from sugar production, effectively eliminating bacteria and other impurities, and thus allowing them to be reused or rejected in accordance with strict standards.

The advantages of VAL INDUS vs. standard treatment processes

Avantages

CAPEX

- Remplacement chaîne de procédés mono-fonctions
- Réduction investissement génie civil

OPEX

- Savings Of energy (division by 2 to 3)
-Few consumables (vs washing and changing filters)

Low ground footprint

Up to 5 times lower - with sound vertical design.

Robustesse et facilité d’utilisation

- Remote control
- No moving parts susceptible to wear or corrosion

Environmentally friendly

- Water loss < 1% flow vs. 30 à 40 %
- Longue lifetimes
- Sludge recovery (siccité > 15%) avec pouvoir méthanogène

Simplified synopsis of VAL INDUS

Synoptic

Process test (by sample or via VAL SKID)

Process test

Each effluent has its own specificities (volumes, charges, temperature, pH...). In this context, Coldep proposes to recover a representative sample of the effluent to be treated and to test the VAL technology to assess its abatement performance in relation to the objectives targeted.

“VAL INDUS has replaced a flotation process that no longer offered the high level of performance desired to treat effluents from our plant. In a very limited floor space, this new process allows us to meet the desired rejection standards. It also valorizes sludge by methanization thanks to a dryness rate twice as high as before. Remote control finally gives us security and an appreciable guarantee of performance.”

Problem

Treatment of waste water generated by processing ready meals (acid with low pH, lots of organic matter, etc.)
Treatment requirement: 150 m³/ j (+/- 5 m³/h)
Sludge produced with a dryness of 8 - 14% (500 t/year)

Objectives

Comply with 2000 COD discharge standards
Valorization, methanization, waste

VAL INDUS (x2 in series)

Ground space: 5 x 5 (25 m² building) for 2 VAL (the first with physical flotation and the second with the addition of chemistry and dissolved air)
Coagulants, flocculants and pH neutralization with soda: automated system under control

Results

Valuation thanks to the methanogenic power of the discharge (cf. reduction in the collection bill with solid material waste component x 3)
Sludge dried 14-15% (500 tons wet/year)
+ 88% reduction in DCO, DBO and MES

VAL SKID: PILOT TESTING, DEPLOYMENT, AND RENTAL OPTIONS

Coldep provides mobile pilot units in containerized or skid-mounted configurations. These allow for on-site testing and validation of technical decisions from the design phase, supplementing the preliminary lab tests conducted with the VAL PILOT.
