Netsol Water has already assisted some of the manufacturing industries, in lowering their operating costs with the help of wastewater treatment and reuse. To maximize pollutant removal, each of these applications includes the use of some of our efficient and advanced wastewater filtration systems.
How is wastewater filtration assisting industries to reuse water?
With the help of Netsol Water wastewater filtration systems, industrial organizations can reduce their cost, by reusing their wastewater in a sustainable manner.
· Pulp and Paper
It is estimated that 80 to 85% of the water used in paper production is used as process water, which means it is used directly in production. A significant portion of that is used in the production of pulp as well. The water in the pulp is strained out during the manufacturing process.
As a result, the resulting water contains a number of contaminants that must be eliminated, before discharge or reuse. In order to reuse the wash water, to reduce water consumption costs and comply with environmental regulations, the wastewater must be treated for BOD, COD, turbidity, and suspended solids.
NETSOL WATER provides a pilot system that includes specialized screen filtration, an electrocoagulation unit, and a dissolved air flotation unit.
As a result, the wastewater filtration systems can reduce BOD levels by 90%, COD levels by 84%, turbidity by 92%, and suspended solids by 99%.
· Power generation boiler feed water
Power generation facilities use large amounts of water for a variety of processes, to ensure the facility operates safely and efficiently. Water is used in cooling towers to keep generators from overheating. On the other end of the spectrum, water is heated in boilers to produce steam, which powers turbines, generating energy.
Many power generation facilities aim to recycle the water they use, in order to operate more sustainably while also lowering operating costs. To that end, we provide a system that meets the operational requirements specified by industrialists. Contaminants in the influent feed water include hardness minerals, dissolved ions, trace hydrocarbons, and a few heavy metals, such as ferric irons.
We plan, engineer, build, and supply the treatment system, which is installed with technical assistance by a local civil engineering and construction partner. To eliminate the dissolved salts, the system uses reverse osmosis, but contaminants are removed first using specialized wastewater filtration systems, which consist of carbon filtration coupled systems, with a scale protection system to ensure optimal feed water quality, for the operation of the RO system.
While paint and pigment manufacturing facilities use water in their processes, the majority of their wastewater is generated by cleaning the numerous machines and equipment’s, used to manufacture water-based paints, solvent-based paints, and resins. Large volumes of sludge can be generated when treating wastewater from these, resulting in significant discharge costs to maintain compliance.
We propose eliminating coarse organic solids by pumping raw influent, from a primary holding tank through a pre-screen filter. The chemical coagulation can be replaced with an electrocoagulation system, which can then be clarified using a sustainable flocculant medium. The final tertiary wastewater filtration system process can use a microfiltration unit, to remove the remaining colour and particulates.
How can we assist?
Netsol Water offers wastewater treatment, which includes Industrial RO Plants, MBR systems, MBBR systems, lagoons, electrocoagulation, and much more. We also provide tertiary wastewater treatment with ROPlants. As a result, it can be used in industrial applications for streams with high TDS levels, and for re-use purposes.
