Industrial manufacturing companies today are generating wastewater. Either they will send offsite for disposal or determine whether it is more cost effective to treat it in-house. Certain manufacturing processes create undesirable wastewater that often must to be chemically treated or hauled away, which often is a significant cost. This expense is often ignored and as a result will have a negative effect on the profitability of the company. Finding ways to efficiently and effectively be compliant with the local POTW (Publicly Owned Treatment Works) is a big focus. Environmental sustainability is a primary focus today with industries working toward becoming “environmentally greener”.
Minimizing risk and maximizing profitability is the main objective today for industrial companies. An optimum solution for these challenges is recycling or repurposing the wastewater through a zero-liquid discharge (ZLD) water treatment process especially in many parts of the country, where the cost of water can be extremely high. In these areas, water conservation is a focus. Finding ways to reuse the water is being examined. Manufacturing operations are often reusing their wastewater but can not achieve this without various methods or systems in place.
ZLD is an advanced wastewater treatment method which leaves zero discharge at the end of the treatment cycle. This method is most effective in mitigating the risks and costs associated with most industrial wastewater. The wastewater is purified, and the clean water is recycled. PRAB offers a wide selection of advanced ZLD systems for wastewater treatment to mitigate risk and reduce costs, including:
An example of water reuse is with oily mop water from cleaning shop floors of oils. Disposal of this wastewater is an issue because there are limits on the amount of fats, oils and grease (FOG) that can be discharged to local POTW’s. Companies will often send this water offsite for disposal, often at a big expense thus eating away their profits. A method being used today is Ultrafiltration. This is a process that utilizes high pressure or forces to push the wastewater through a semipermeable membrane, which filters out the emulsified oil and solids, and the filtered water (or filtrate) passes through the filter media. Instead of having to pay an outside disposal service to have the wastewater hauled away, the filtered water is purified enough to be used for make-up of the mop cleaning solution.
With POTW’s becoming more stringent with the discharge requirements, manufacturing companies are looking to find treatment systems that fall within their budget to become more compliant in discharging the treated water to their local municipalities or for water reuse. Having a good understanding of what your wastewater consists of is important in determining the most efficient means to treat it. The range of pollutants will vary in the wastewater, which will impact the cost of the various treatment approaches, noted above. Pores sizes will vary in micron size with different technologies. Selecting the proper system must be carefully evaluated. PRAB Wastewater provides a consultative approach in finding the most suitable technology for the specific applications.
Having a thorough understanding of the chemical make-up of the wastewater is needed to determine what technology that is most cost efficient and most effective in removing the heavy metals, removal of oils and greases and reduction of chemicals or organics (i.e.- carbon bearing compounds). PRAB will match the right technology for your specific application. Knowing which system falls within your budget must be considered. Understanding the value proposition and the overall savings and the return on investment of the appropriate technology will be accomplished.
