3 Water Specialists for the Food & Beverage Sector Our Role in your Industry We all need water. In the food industry, businesses consumption of water ensures that the food we eat is kept clean and made safe for consumption itself. It is an ingredient. It condenses, dissolves and extracts. Water washes raw materials. It heats in boilers, chills in refrigerators and cools equipment. In fact, water is such an integral component in food production, without effective management, production and food safety can be affected. This is a challenge, and the bigger your company, the bigger the challenge. Now, more than ever before, businesses are required to demonstrate a commitment to water sustainability. Whatever foodstuffs you produce, whatever type of operation you are responsible for, whether it involves industrial or kitchen wastewaters, prepared meals or in-flight catering, the chances are that Ovivo already has experience in your sector. Food production can be highly seasonal. Inputs and outputs can vary accordingly. Ovivo s knowledge of the food and beverage industry is rooted in our successful experience of helping factory operations achieve the results they require throughout the year. Ovivo specializes in designing, constructing and providing highly technical solutions for the treatment and recycling of wastewater across industries all over the world. However you help your customers fulfil their fundamental food needs, the chances are we can help you. Managing water from source to safe disposal Ovivo can recommend solutions that will manage the water resources at your disposal safely and effectively, from pre-treating meats, fruits and vegetables on factory processing lines, to treating wastewater for reuse or disposal. Every business has its own particular water needs dependent on location. Ovivo understands how water sources impact on processes. Food businesses handle the very substance of human wellbeing and are regulated accordingly. We appreciate that the means of disposal will determine the processes best suited to your own business. A suitable solution for every client site Your plant may process meats and require technology to deal with fats, feathers and offal. It may process potatoes, corn or soya and have specific requirements for dealing with starch. The broad range of dairy products creates varying forms of wastewater which each need their own forms of treatment. It may make drinks and require water to clean fruit at the outset of a process and clean bottles for packaging at its close. As a global water specialist, Ovivo has the capability to recommend and implement end-to-end solutions that extract the full value from water resources at your disposal so that you can maximize the output of your plant. Creating Value Ovivo s advanced water treatment plant allows us to recycle more than 75% of our wastewater, or around 3ML/day. The savings in mains water and discharge costs easily outweigh the operational costs of the plant, which should pay for itself in a matter of years. 1

4 Ovivo - Industrial Markets Industries in which we work Dairies Ovivo s broad experience of dairy food processing helps us to anticipate the wastewater characteristics and fluctuations of dairy wash water, be it mild from fluid milk plants, or concentrated from cheese manufacturers. Poultry Ovivo s preliminary treatment by primary screening removes bulk solids (i.e. feathers, offal and foreign material). Finer solids are removed after chemical balancing in a Dissolved Air Flotation system (DAF). Ovivo s DAFs can remove more than 90% of fats and solids and 70% of the Biochemical Oxygen Demand (BOD) load and produce water of suitable quality for discharge to most municipal treatment plants. Sequential Batch Reactors (SBR), Moving Bed Bioreactors (MBBR), Membrane Bioreactors (MBR) or conventional activated sludge plants are secondary treatment processes which prepare poultry wastewater for discharge to waterways. Low and high rate anaerobic processes can be incorporated into the design, but such systems are often limited in nutrient removal and are usually not appropriate as a single stage of treatment. Ammonia and nitrogen levels can be high. Primary balancing tanks equalize flow variations and concentrations. A facility to bypass or just store product spills is good practise, as surges of highly concentrated wastewater upset both primary and secondary treatment processes. The ph of dairy wastewater is reduced to deemulsify milk fats prior to DAF allowing excellent fat, oil, grease, BOD and suspended solid reductions. Most commonly secondary treatment processes are based on MBBR or MBR technology. Both processes are more tolerant to sludge bulking, a phenomenon commonly found in biological treatment of dairy wastewater. Meat Processing Wastewater from meat processing usually contains high levels of fat, solids, nitrogen and phosphorous. Unacceptable Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) levels require treatment too. Typically a preliminary water treatment stage involves screening to remove bulk solids, such as offal and other foreign material. After flow equalization, Ovivo removes finer solids by DAF. With an appropriate chemical regime, a DAF system can remove more than 90% of fats and solids and 70% of the BOD load. This treatment will often provide water of suitable quality for discharge to most municipal treatment plants. Breweries Brewing produces a wastewater stream that is high in organic loading. Most of the organic component is soluble and requires biological treatment. Brewery wastewater is highly biodegradable and reacts rapidly, so biological treatment is efficient and simple. Ovivo can recommend the most effective treatment of wastewater depending upon the outlet for disposal, be it the local sewage treatment or recycling plant, river or ocean. Preliminary screening removes bulk solids. Then a high-rate anaerobic process is ideal because brewery wastewater usually contains high levels of soluble BOD. Ovivo can achieve more than 90% reductions in COD /BOD loads this way. Any gas produced can be flared off or, for larger applications, used to fire a boiler or combined heat and power unit. If required, secondary treatment by SBR, MBBR or MBR leaves wastewater of a quality suitable for discharge into the environment. 2

5 Water Specialists for the Food & Beverage Sector General Food Screening as a primary treatment removes gross solids and foreign material. DAF removes over 90% of finer fat and solids present. For sewer discharge, some coagulation, ph correction and flocculation processes are normally used. Secondary treatment processes SBR, MBR, MBBR, conventional activated sludge plants - enable discharge to waterways. Low and high rate anaerobic processes are also quite common when nutrients are not present in significant quantities. Potato & Chips High soil and grit volumes in raw potato processing require solids-handling when conveying and dewatering plant. Ovivo s effective, two-stage process for treating starch reduces chemical use and the quantity of sludge for disposal. DAF removes starch from sludge so it can be reused. Ovivo also supplies specialist process equipment to pre-treat and handle hot caustic boil-outs and other highly concentrated streams. Ovivo recommends SBR, MBBR, MBR, or conventional activated sludge plants where stringent regulations require them. We can also incorporate low and high rate anaerobic processes into the design when appropriate. Ovivo has constructed several recycling plants in the potato chip industry, which incorporate tertiary treatment processes such as Ultra Filtration (UF), Reverse Osmosis (RO), disinfection and water conditioning, allowing you to reuse more than 70% of your wastewater in the processing factory. Vegetable & Fruit Wastewater characteristics will vary greatly depending upon the types and condition of fruit or vegetable used and the processing techniques deployed (e.g. washing, blanching, peeling etc). Using brine or chemicals in processing involves specialist clean-up methods. In the beverage industry, decomposable organic compounds (leading to BOD) and suspended solids of various types are contaminants of particular concern. Elevated loadings of nutrients (nitrogen and phosphorus) also need to be addressed. Screening and ph correction are essential as primary treatments. Anaerobic processes remove 90% of the soluble BOD load. Subsequent aerobic processes reduce BOD to acceptable discharge levels whilst simultaneously removing nutrients. Sludge dewatering plants, screens and solids handling equipment require careful design, which Ovivo applies to every client s circumstance. Creating Value Wastewater production from fruit and vegetable operations can be highly seasonal and variable. Ovivo s knowledge of factory operations and the sources of wastewater is vital for the effective design of wastewater treatment plants. 3

9 Water Specialists for the Food & Beverage Sector Case Study Jaspers, Treburley & Botathan Cornwall, UK Jaspers is the West Country s foremost independent beef and lamb producer. Brief Jaspers utilized approximately 17,000 m 3 of water each year, and their annual charges for wastewater disposal are 100,000; additionally, the Treburley and Botathan sites consumed large amounts of costly potable water in low-grade wash-down applications. Solution Jaspers selected Ovivo s Membrane Bioreactor (MBR) to treat the low-flow, high-strength wastewater stream at both sites. Almost immediately, this simple, low-cost and low-maintenance system provided a cost-effective solution to treating the process effluent. First screened by a 3mm perforated plate automatic screen, influent wastewater then enters the MBR s treatment tank where the mixed-liquor activated sludge degrades the Chemical Oxygen Demand (COD). This treatment tank contains flat-sheet membrane panels to separate treated effluent from the mixed-liquor activated sludge and to remove bacteria and viruses. Due to the high influent COD load, the treatment tank incorporates a fine bubble diffuser air zone to ensure efficient oxygen transferred to the mixedliquor activated sludge. Treated effluent is stored prior to reuse, and the unused high quality permeate is discharged into a local watercourse. In just four months, 60% of the treated wastewater at the Treburley beef plant had already been reused in low-grade applications, while the lamb abattoir in Botathan was reusing 90% of its water. Outcome The quality of the final effluent has far exceeded original expectations, with Biological Oxygen Demand (BOD), Total Suspended Solids (TSS) and Nitrogen As Ammonia (NH 4 N) concentrations all less than 10 mg/l - and often less than the limits of laboratory detection. Ovivo s efficient membrane filtration system, and the reuse water it generates, enabled Jaspers to be the first abattoir in the UK to receive a Certificate of Environmental Benefit, and so instead of disposing wastewater to land, Jaspers are now making a net saving of around 90,000 per annum. How we created value Significant OPEX savings. Payback period reduced to less than 5 years % water reuse. Saving us money. 7
