EPAS helps you with all your process water questions
Integrated water management is becoming increasingly important in the industry. This trend does not only arise from the perspective of having to limit waste water discharges (and the associated (high) costs), but also from the perspective of having to limit the intake of ground- and/or tap water. Rationalisation of the water usage within the company, and the use of alternative water sources can often significantly reduce the "water footprint" of the company and the high costs for water intake and discharge. Lots of waste finds its way to the installation via the water. Rational water use should not only focus on water, but should integrate a minimal loss of product and waste matter.
EPAS offers help with all your questions related to process water, in addition to its expertise on wastewater. EPAS offers help with the following process water issues:
- Wateraudits: EPAS screens the water usage within your company and describes the main users and main points of discharge within the process. Water audits are the basis for a further investigation into the possible use of alternative water sources and reuse/recycling within the company.
- Possible use of alternative water sources: EPAS screens your options for use of alternative water sources: rainwater, surface water and reuse of wastewater. EPAS offers you advice on the availability and usability of these sources and the necessary purification steps, both qualitatively, as well as quantitatively.
- Possibilities for water recycling within the process: based on a water (mass) balance and analysis of the water quality (concentration) of the wastewater streams of the different processes, a feasibility study can be made of the possibilities to recycle certain streams to other places within the process. An example is the reuse of slightly polluted rinsing water for primary rinsing, or even in cooling towers. EPAS will describe the different possible scenarios and calculate your possible savings.
- Possibilities for reuse of waste water & design of installations for waste water reuse: this is closely related to EPAS' experience in wastewater treatment. By a better design of your wastewater treatment, your effluent quality can be upgraded to make reuse as process water (via additional treatment steps, such as membrane processes and/or advanced oxidation) possible. This leads to significant water savings and very short pay-back times for the investment. EPAS will design different scenarios for possible reuse of wastewater, depending on the characteristics of your wastewater. The additional treatment steps will be dimensioned and the economical and technical feasibility will be assessed. EPAS also offers the option of testing the proposed treatment concepts in practice.
- Design of concepts and installations for treatment of alternative water sources to process- and/or drinking water quality: comparable to the design of installations for wastewater reuse, EPAS offers you advice towards concepts and installations for rainwater and surface water purification.
- Support and troubleshooting for existing water treatment installations: this not only includes wastewater treatment, but also process- and drinking water treatment.
- Professional support for membrane installations: these include installations for wastewater reuse, treatment of rinsing water, purification of surface water,... . The knowledge extends from microfiltration to ultrafiltration, nanofiltration and reverse osmosis, as well as EDI/CDI processes.
- Support for design and operation of ultrapure water installations: design and operation of RO installations, ion exchange processes, polishing activated carbon filters, ...
- Audits for cooling systems and cooling water circuits: this is not only focused on water usage within these processes, but also on water quality aspects of the cooling water (calculations for addition of antiscalants, corrosion-inhibitors and disinfectants). Moreover, EPAS offers advice related to prevention of Legionella.
All our process water-related advice and research is supported by in-house laboratory analyses (organic and inorganic, as well as biological parameters (including Legionella)). When required, all concepts are also tested on lab- or pilot-scale.
In case you are interested or would require some more information, please contact us and we will respond to your question as soon as possible.
