On average, big brewers product 7 to 10% of wastewater, also known as effluent, for every gallon of beer they brew. Among craft brewers, that number is closer to 3 liters of wastewater per liter of beer, and many craft brewers seek to reduce that number even further. Here are some of the techniques they are using to accomplish their goals of minimizing waste and reusing effluent in the beer-making process.
After the beer-making process, the wastewater contains high levels of organic compounds including spent grains or carbohydrates, sugars, yeast, and proteins. These solids would cause problems if they were dumped into the sewer system of most municipal water treatment plants because of the sheer amount of them that would enter the system.
Wastewater produced by breweries is rather unique. The brewing process creates alcohol, sugars, and proteins that all end up in its wastewater. If brewery wastewater rich in nutrients is discharged without the correct treatment it can seriously interfere with natural ecosystems.
In order for a brewery to safely release their wastewater into their city's treatment system, they need to first remove most or all of these solids. There are several safe and eco-friendly ways to do this.
Fluid Sep Technologies offers conventional and advance methods of treatment for breweries effluent.
A cement plant wastewater treatment system needs to be highly effective in order to remove the miniscule particulate that remains after cement production.This becomes even more important when a closed system – the industry standard – is in place and the waste water is reused repeatedly.
The Fluid Sep Technologies has worked with cement manufacturers for many years, so we understand these challenges, and we’ve built systems that can handle them. Our systems can filter solids from water to below 1 micron. Additionally, our components, like filter presses and clarifiers, are built to last from high-grade industrial materials that can stand up to the harshest conditions. We’ll mix and match these components to create a system that not only provides you with optimum wastewater treatment, but also works seamlessly with your existing equipment.
• A reduction of water usage.
• Automation opportunities.
• Expandable filter presses that grow as your demand does.
• Eliminate wastewater discharge compliance issues.
Chemicals and Petrochemicals can be defined as a large group of waste water from chemicals, petroleum and natural gas and used for a variety of chemical purposes. Chemicals and Petrochemical plants are in the business of developing substances such as hydrogen, carbon monoxide, synthesis gases, chemicals such as ethylene and its derivatives, benzene and toluene to name a few.
Wastewater treatment in Chemicals and petroleum refineries is a complex process, with demanding environmental management challenges as byproducts can be both volatile and toxic. Petrochemical wastewater often requires a combination of treatment methods to remove oil and other contaminants before discharge. Issues such as groundwater contamination; aromatics; oil, grease and organic removal, and VOC control have to be addressed in order to comply with environmental regulations and maintain a good customer image.
An increased understanding of requirements of the petrochemical end-user is gaining importance as industry needs change due to stricter regulation and environmental laws. It’s important equipment manufacturers keep abreast of these requirements to capitalize on future opportunities. End-users are forced to become more aware of what types of waste they’re creating and discharging, and how they can adjust their current treatment equipment to meet new demands.
We at Fluid Sep Technologies provide different technologies like neutralization, coagulation/flocculation, floatation/sedimentation/filtration, clarification and biodegradation (e.g., aerated lagoon, rotating biological contactor and activated sludge). A final polishing step using filtration, ozonation, activated carbon, or chemical treatment and Membrane system to reuse, recycle the waste water in to pure water for process.
A large network of distilleries has been established in India which has been recognized as one of the most polluting agro-based industries generating huge quantities of distillery effluent.
There are more than 350 distilleries in India which release 45 billion liters of wastewater yearly. For the production of every one liter of alcohol nearly 12 -14 lit. of effluent is discharged. Every distillery unit is generating 5-10 lakh lit. of raw effluent per day.
Molasses form the sugar factory is the major constituent in the sugar Industry. Molasses is the by-product of sugar Industries. The effluent of distillery is known as spent wash. Spent wash is the approximately 13-16 times more by volume to that of the alcohol. It is highly organic brown in color. Spent wash having BOD 40000-60000 mg/lit and COD about 1, 20,000-1, 40,000 mg/lit.
So it is very troublesome to treat spent wash. It is therefore obvious that some treatment is necessary to minimize the deleterious effects before the waste is discharged onto land. Disposal of these effluents after proper treatment is favorable approach because after by using appropriate measures effluent comes within limits and pollution load is reduced.
We at Fluid Sep Technologies provides optimized and customized solutions with turn key projects for water treatment and waste water treatment for Distillery Industries.
Food and beverage processors typically consume high volumes of water and generate high organic-strength wastewater in batch mode. These high-pollutant loads increase the cost of treatment and may require significant storage volume for equalization at the head of the treatment system. Major pollutant loadings often include biological oxygen demand (BOD) and chemical oxygen demand (COD), total suspended solids (TSS), fats/oils/greases (FOGs) and nutrients in varying concentrations.
Wastewater plants at food and beverage manufacturing facilities are constantly challenged by changes in influent conditions caused by load shocks; temperature changes; increases in production; changes in manufacturing operations; spills; washwater surges; operation malfunction; and limited equalization capacity. Effectively treating this wastewater is often difficult, for reasons numerous and varied. In many cases, conventional activated sludge treatment systems are not capable of handling large, sudden variations in BOD, COD and nutrients.
We at Fluid Sep Technologies provides optimized and customized solutions with turn key projects for water treatment and waste water treatment for Food and Beverages Industries.
The metal surfaces treatment industry is comprised of a large variety of activities whose purpose is to treat metal surfaces, protecting them from corrosion, improving their resistance to wear and erosion, or enhancing their appearances with metallic coatings.
These activities or treatments can be grouped into two main categories:
1. Cleaning processes and surface preparation (degreasing, pickling, …).
2. Metallic coatings and obtaining surface finishes (electroplating, anodizing, immersion, …).
During these treatment processes, large amounts of wastewater or effluents of diverse composition are generated according to the treatment the metal surfaces have undergone.
Different technologies exist for treatment of wastewater and effluents generated by the metal surface treatment industry. Treatment choice will depend on the composition of the effluents as well as the objectives and environmental needs of the company: zero liquid discharge, water reuse, adjustment of discharge limits, obtaining by-products, etc.
Reverse osmosis produces water that can be returned in a closed circuit through a washing process. On the other hand, a concentration of nickel salts can be returned to process baths (90%-97%). Thus, nickel salts are saved in addition to other components of the bath such as rinse water. Reverse osmosis can be utilized in other processes such as brass, copper plating, silver, zinc, etc.
In addition, reverse osmosis can be employed in the regeneration of wash waters. Depending on flow rejections, with this system of reverse osmosis, one can obtain water between 100-500 μS/cm. This technique is applicable with diluted water from the majority of processes, with the exception of very oxidized baths.
Ion exchange resins permit the elimination of metal contaminants and the regeneration of rinse water, thus returning large amounts of high quality water with low ion content. This system returns the water to rinsing tanks through the design of the installation operating in a closed circuit. Recirculated rinses with ion exchange resins operating according to how they are intended, can work for a long time, with conductivities below 50 mS / cm, even below 5 mS / cm in the case of final rinses.
We at Fluid Sep Technologies provides turn key solutions for the metal industries
Mining effluents can be caused by:
• Wash waters.
• Flow Process acids.
• Water leaching, flotation and concentration.
• Effluents from refining and gas scrubbers.
A mine generates large amounts of highly concentrated wastewater due to contact between water and various types of minerals. The origin of these effluents can be found in the distinct processes undertaken in mining, in addition to drainage from rainfall.
Meanwhile, rain that infiltrates the tailings of the mine can also cause oxidation, hydrolysis, washing, etc. producing a highly contaminated wastewater.
The contact between minerals and water, by process or rain, can produce distinct reactions. The effluents produced are of diverse compositions, depending upon the nature of each mineral, since there are those more or less soluble, hydrolysable and non-hydrolysable, as well as sorbents and non-sorbents. Thus, the discharge of such wastewater can provoke serious consequences in mining and its environment by completely altering water chemistry.
Traditionally, physico-chemical or biological methods have been used to treat these effluents. Presently, zero discharge has proven to be the smartest choice. It ensures the protection of the ecosystem and provides for water reuse in places where access to water is limited. In addition, zero discharge is most economical long-term alternative once installation costs have been recuperated.
We, at Fluid Sep Technologies can guarantee zero liquid discharge , depending on the composition of the effluent, with other membrane technologies or pretreatment processes. That can achieve a 95% rate for pure water ready to be reused. Moreover, solids rejected in the process can to be sent to waste management.
Paper, perhaps the most widely used material in everyday life, consist of a network of plant fibers with a high cellulose content that have been treated using various water-based processes, placed on a sieve, and finally dried. Although these fibers can be obtained from numerous different plants and trees, the most important source used is conifer wood due to the length and strength of its fibers. One third of all the wood processed worldwide is used in paper and pulp production.
Paper manufacture consumes a large quantity of resources, especially water and energy, although it also requires large quantities of raw materials and chemicals. Approximately 2-18 m3 of water (depending on the effluent management system used and whether water is recovered) and between 2 and 2.5 tons of wood are required to produce one ton of paper.
During the manufacturing process, water acts as a disintegration medium for the raw materials, a transport for fibers, and for paper formation. The process commences with separation of cellulose from the other substances (lignin, oils, resins, etc.), which represents 50% by weight. To extract cellulose fibers, the wood must first be crushed (mechanical pulp) or wood chips subjected to a chemical treatment (chemical pulp). In the latter case, treatment involves either the use of an alkaline product (sulfate or caustic soda) or a sulfite. In both cases the aim is to solubilize the lignin to release the cellulose fibers. There are major differences between the two treatments. Thus, the alkaline method generates black effluents that are highly contaminating and are generally treated to recover the sodium sulfide and caustic soda. In the sulfite method, some of the chemicals used, such as sulfuric acid, can also be recovered. However, those chemicals that cannot be recovered are lost with waste effluent along with remnants of cellulose that have not been retained, thus meaning that the effluent has a high COD. If the pulp is obtained mechanically, the quality of the paste obtained is lower but less liquid waste is produced.
Fluid Sep Technologies provides the best and cost effective solutions to treat the waste water with advance technologies
Most of the wastewater is produced by washing equipment at the end of the production process. There are other smaller and polluting amounts from purifying the water used (rejects from reverse osmosis and regeneration of ion exchange resins), cleaning of the installations, effluents from laboratories, etc.
Pharmaceutical industry wastewater varies enormously in flow and composition, depending on factors such as the production rate, the specific preparation being carried out, which activities are generating the waste water, etc. All these variables mean that the pollution of the final effluent can be very diverse and variable over time. Generally, these wastewater contain:
• A high content of organic matter, a large part of which is easily biodegradable (alcohol, acetone, etc).
• Slowly biodegradable organic compounds and refractory substances (aromatic compounds, chlorinated hydrocarbons, etc).
• Inhibiting and toxic compounds (antibiotics).
• Soaps and detergents with surfactants.
The best techniques for treating the effluents generated by this type of industry will depend on each specific case, given their considerable variation and the wide range of possible compounds. We Fluid Sep technologies has best technologies to treat the waste water that may be the most competitive according to the various factors, giving the advantages and weal points for each type of pharma effluent.
The textile industry is characterized by the fact that its activity requires a high consumption of water, energy and auxiliary chemical products. This is translated into the generation of a large amount of wastewater, with high concentrations of dyes, biodegradable and refractory organic pollutants, suspended matter, surfactants, salts and chlorinated compounds. In addition, because in the great majority of cases production is intermittent, there is a significant variability in the amount of the wastewater generated and the nature of its contamination. These characteristics make it an industrial effluent that is difficult to treat.
The regulatory requirements and the need to save energy and reuse water in industry make it necessary to develop new processes that will enable us to eliminate the water pollution and make it possible to reincorporate the effluent in the production process.
One of the parameters that requires the greatest effort for its elimination –with reasonable costs– is color. The Dyes are not usually toxic, but they are not very biodegradable. In an urban wastewater treatment plant it is estimated that only 20-30% of the color in the effluent will be eliminated. In addition, the dyes are evident in the water in very small concentrations, so the elimination yield must be very high.
Fluid Sep Technologies offers the systems which can remove Other contaminants like COD, TSS and rest of the parameters which surely treats with advanced membrane technologies.
