Can sludge be incinerated?
There are several reasons why businesses continue to send their effluent to outside contractors for incineration. These may include a lack of room for treatment equipment, an inability to get discharge licenses, or the fact that they only produce in tiny batches.
They may be unaware of the most recent advancements in water treatment technology, which means that even extremely contaminated water may frequently be effectively treated. Moving water off-site for treatment, on the other hand, might be difficult. Then there's the matter of temporary storage and the physical challenges it entails with pipes and storage tanks. Second, there's the expense — not only the monetary cost, but also the environmental impact.
Removing water for treatment somewhere has a negative impact on your company's carbon footprint, which environmentally conscientious investors may become aware of, perhaps affecting the bottom line indirectly. Furthermore, constraints on the calorific value of dirty wastewater that may be handled are very fluid right now, which does not help responsible businesses seeking the security of long-term solutions. Essentially, incineration may appear to be inexpensive at first glance, but there may be other hidden expenses lurking around the corner.
Alternative to wastewater incineration
The incineration of dirty water consumes a significant quantity of natural resources.
Aside from the voyage to the incineration facility, the water must first be transformed into sludge using evaporative processes in order to be treated. Because this water can be harmful, further care must be taken.
The ‘sludge cake' is then burned at roughly 800°C when water accounts for only around 25-30% of its capacity. Natural gas is frequently employed as an energy source in the incineration process, and what comes out of the incinerator's chimney is frequently unknown. According to some sources, incinerators are among the worst CO2 emitters.
Water with a low calorific content is seldom acceptable for incineration
For obvious reasons, many incinerator contractors are now only taking effluent with a high calorific value. Manufacturers whose effluent does not "pass the test" are already being compelled to seek alternate solutions.
The storage of dirty water on-site has its own set of concerns
Larger firms may require specialized tanks, which will have their own set of maintenance and personnel difficulties. Smaller businesses or those with less water-intensive or batch operations may employ 1000 litre IBCs, which, while inexpensive, have their own storage, safety, and handling difficulties. Leaks, for example, are a continual worry, especially when storage temperatures change.
Some businesses we speak with believe that their water use is so minimal that it is not worth investigating treatment options.However, we can usually demonstrate that, in the long run, a Netsol system will be a better economical proposition, both financially and environmentally.
Netsol Water can help with the removal of numerous difficult substances from wastewater, frequently eliminating the requirement for treatment and allowing for internal re-use or local disposal.
We've discovered that when businesses come to us with problematic water containing stubborn substances that we can treat, we can typically build an on-site water treatment system.
The treatment systems do not have to operate continuously – if necessary, they may be employed for intermittent operation, making them perfect for batch manufacturing.The system provides a one-of-a-kind mix of adsorption and electrochemistry, utilizing all of the benefits and none of the downsides of either.
