Why is knowledge of food and agricultural wastewater important?

Knowledge of characteristics of food and agricultural wastewater is essential to the development of economical and technically viable waste-water management systems that are in compliance with current environmental policy and regulations.


What are suspended solids in wastewater?

Solids in wastewaters come in two forms: suspended solids (nondissolv-able) and dissolved solids. Suspended solids are nuisances because they can either settle on the bottom of the receiving water body or float on the surface of the water body. Either way will affect the ecological balances of the receiving water body. Solids that readily settle are usually measured with an Imhoff cone, in which a known amount of water sample is poured in the cone and the amount of the solids settled at given times is recorded and compared with the admissible amount of settling solids in the waste-water for discharge. The acceptable settling solids level is usually determined by environmental regulations and as a rule of thumb, discharge of wastewater or treated wastewater is not acceptable if the result of Imhoff testing shows that the water sample contains settling solids after 10 minutes of testing.


What is food waste?

Wastewater from food processing operations is defined by the food itself. Food and agricultural wastewater contains dissolved organic solids from various operations and debris from mechanical processing of foods, such as peeling and trimming, and hydrodynamic impacts in washing and transporting.


What is the dairy industry?

The dairy industry is one of the most important agricultural processing industries in the United States and has grown steadily in the last decades. Wastewaters originate from two major dairy processing—from fluid milk at the receiving station and bottling plants, but increasingly more importantly at the processing plants that produce condensed milk, powdered milk, condensed whey and dry whey, butter, cheese, cultured product, ice cream, and cottage cheese. The milk itself has a BOD5 of 100,000 mg/l and washing plants that produce butter and cheese may produce a waste-water with BOD5 of 1,500 to 3,000 mg/l. Dairy processing uses raw materials beyond milk and milk-related materials; nondairy ingredients such as flavors, sugar, fruits, nuts, and condiments are utilized in manufacturing ice cream, yogurt, and flavored milk, and frozen desserts. The pollutants can enter the wastewater streams through spills, leaks, and wasting of by-products. Apart from whey, which is acidic, most dairy wastewater streams are neutral or slightly alkaline, but they tend to become acidic rapidly due to the lactic acid produced as a result of fermentation of lactose.


How hot can wastewater be?

It is generally accepted that the temperature of discharged wastewater to a receiving water body cannot exceed 2-3°C of the ambient temperature in order to maintain population balance of the aquatic ecosystem of the receiving water body. Wastewater from some food operations such as retort should be cooled before discharge or biological treatment.


What are the processes used in the fishery industry?

The production processes used in the fishery industry generally include the following: harvesting, storing, receiving, eviscerating or butchering, precooking, picking or cleaning, preserving, and packaging. Harvesting provides the basic raw materials (fishes) for processing and subsequent distribution to the consumer. Once fishes are aboard the fishing vessel, the catch either is taken directly to the processor, or is iced or frozen for later delivery. Preprocessing may be undertaken aboard before the catch is sent to the processing plant. It may include beheading shrimp at sea, eviscerating fish or shellfish at sea, and other operations to prepare the fish for butchering. Wastes from the butchering and evisceration that are sizable are usually collected in the dry form, or screened from the wastewater stream, and processed as a fishery by-product.


Wastewater

Cities and towns generate a stream of water that has already been used, such as for domestic purposes. This stream of water represents a waste product which must be either disposed of safely or re-used downstream as a resource. Apart from its value as water, it may also contain nutrients which benefit agricultural production.


Saline water

Production of salt-tolerant crops can generate economic value from saline water where the environmental conditions are conducive.


What is agricultural waste?

Agricultural waste is defined as unwanted waste produced as a result of agricultural activities (i.e., manure, oil, silage plastics, fertilizer, pesticides and herbicides; wastes from farms, poultry houses and slaughterhouses; veterinary medicines, or horticultural plastics). Pesticides and herbicides are used to control pests, but when persistently applied resulted in being accumulate in soil where it may be harmful for beneficial microbes and pollinators. Most pesticides and fertilizers are water-soluble and can leach and enter into the water body as well as enter into food products. This can cause serious health diseases in humans including cancer, Parkinson’s disease, Alzheimer’s disease, birth defects, and reproductive disorders (Mostafalou and Abdollahi, 2013 ). Pesticides can also kill nontargeted plants, birds, and other wildlife and have a large impact in the quality and fertility of the soil. Some of the fungicides also contain mercury which has a negative impact on the functioning of the nervous system and also affects the kidneys.


What is the second technology used to convert agricultural waste into animal food?

What are the four corner stones of agricultural waste?

The four corner stone technologies for agricultural waste are animal fodder, briquetting, biogas, and composting (ABBC technologies). These technologies can be developed based on demand and need. In principal three agricultural waste recycling techniques can be selected to be the most suitable for the developing communities. These are animal fodder and energy in a solid form (briquetting) or gaseous form (biogas) and composting for land reclamation. There are some other techniques, which might be suitable for different countries according to the needs such as gasification, fiber boards, pyrolysis, etc. These techniques might be integrated into a complex that combine them altogether to allow 100% recycling for the agricultural waste. Such a complex can be part of the infrastructure of every village or community. Not only does it allow to get rid of the harms of the current practice of agricultural waste, but also of great economical benefit.


What are the three categories of animal by-products?

According to the regulation 1774, animal by-products belong to three categories ( Table III.2.5 ). Category 1 contains materials with the highest risk for public health, animals, or the environment and must always be disposed by incineration or in special cases buried in special landfills after pressure sterilization.


Is agricultural waste a waste to wealth?

Using agricultural waste as animal feed, fish feed, or as constituent in feed preparation is a waste to wealth initiative. However, many agricultural wastes are unsuitable for direct consumption by animals as they need to be treated mechanically and chemically to make them edible. Roughage and fiber residue are often low in nutritional value and need supplements to enrich them.


Why Treat Wastewater?

It’s a matter of caring for our environment and for our own health. There are a lot of good reasons why keeping our water clean is an important priority:


Wastewater treatment

The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.
