5 Considerations When Managing An Industrial Wastewater Treatment Plant

VIDEO ON THE TOPIC: How Do Wastewater Treatment Plants Work?

Do you know what happens to your water when you pull the plug, flush the toilet or drain the washing machine? Well, it's worth knowing. This so-called 'wastewater' is not only a vital resource but, after treatment, will be released to our land, waterways or the ocean.

Used water from toilets, showers, baths, kitchen sinks, laundries and industrial processes is known as wastewater. Domestic households produce an average of —L of wastewater per person every day! Ninety-nine percent of this wastewater is water, the other one percent is the contaminating waste.

Much of the wastewater we produce has been changed in a way that means it cannot be used again unless it is treated. Changes made to water that turn it into wastewater include:. Wastewater from the sewerage system is sent to the sewage treatment plant for treatment before it is released back into the environment.

Sources of wastewater include homes, shops, offices and factories, farms, transport and fuel depots, vessels, quarries and mines. Water used in toilets, showers, baths, kitchen sinks and laundries in homes and offices is domestic wastewater. Wastewater from manufacturing and industrial operations such as food processing or metal refining is industrial or trade waste.

This includes liquid waste from any process e. Stormwater, a form of wastewater, is runoff that flows from agricultural and urban areas such as roofs, parks, gardens, roads, paths and gutters into stormwater drains, after rain. Stormwater flows untreated directly to local creeks or rivers, eventually reaching the ocean. For more information see the department's brochure Stormwater - An important natural resource to protect and Caring for our water. In Queensland, most wastewater is treated at sewage treatment plants.

Wastewater is transported from domestic or industrial sites through a system of sewers and pump stations, known as sewerage reticulation, to a sewage treatment plant. Local governments build, maintain and operate most sewage treatment plants.

Operators are licensed under the Environmental Protection Act to discharge treated wastewater at an acceptable environmental standard into waterways. The Act is administered by the department. The Department of Natural Resources advises local governments about managing, operating and maintaining sewerage systems and treatment plants. In unsewered areas, local governments may require householders to install individual or household sewage treatment systems to treat domestic wastewater from toilets, kitchens, bathrooms and laundries.

The Department of Natural Resources authorises the use of household systems when they are proven to be effective. Local governments will approve their use within the local area. Most stormwater receives no treatment. In some new subdivisions, treatment of some stormwater to remove litter, sand and gravel has begun using gross pollutant traps.

Removes solid matter. Larger solids, such as plastics and other objects wrongly discharged to sewers, are removed when wastewater is passed through screens. Smaller particles, such as sand, are removed in grit traps. Wastewater then flows into large tanks where solids settle and are removed as sludge. Grease and scum are skimmed from the surface. Uses tiny living organisms knows as micro-organisms to break down and remove remaining dissolved wastes and fine particles.

Micro-organisms and wastes are incorporated in the sludge. Removes nitrogen and phosphorus nutrients that could cause algal blooms in our waterways and threaten aquatic life. Algal blooms can cause visual pollution; in some circumstances, use up dissolved oxygen essential for aquatic life; and some forms may be toxic.

Nutrient removal is not available at all sewage treatment plants because it requires expensive specialised equipment. It is becoming more common in Queensland. Clear liquid effluent produced after treatment may still contain disease-causing micro-organisms. If this effluent is released into waterways such as rivers or the sea, the micro-organisms will eventually die out. Until this happens, these waterways could be a health risk. Where people use these waterways, effluent needs disinfection to make it safe for release.

Removes disease-causing micro-organisms. Suitable and cost-effective disinfection methods for cities include adding chemicals to effluent and irradiation with ultraviolet light. In less populated areas, effluent may be held in lagoons or ponds for several weeks, allowing micro-organisms to die off before the effluent is released. Wastewater can only be disposed of as permitted by a licence under the Environmental Protection Act , administered by the department. This usually means wastewater has to be treated or contaminants removed before it can be discharged to waterways.

Most wastewater flows into the sewerage system. Under the Act, local governments administer approvals and licences for environmentally relevant activities ERAs involving wastewater releases that might have a local impact. For example, industry can:. The EPP is an important tool for ensuring that the broad environmental protection measures included in the Environmental Protection Act are better defined when it comes to the specific issues of protecting our water. The EPP requires local governments to prepare and implement sewage management plans to ensure health and environmental standards are met and to minimise unnecessary discharges of pollutants from sewage treatment plants.

Tests can be carried out on the spot for water quality measures such as temperature, pH and dissolved oxygen. Otherwise, samples are taken for laboratory analysis. Often many tests are needed to establish the levels of each of the different pollutants such as oils, heavy metals and pesticides in water. Monitoring provides factual information about water quality and can confirm that licence conditions are being met.

The information obtained through monitoring provides the basis for making water quality decisions. Industries must test their own discharges to ensure they meet their licence conditions. The department randomly checks industry to ensure that testing techniques and water quality standards are being maintained. If problems are found, the licence holder can be ordered to carry out works immediately to rectify problems. Should problems continue offenders can be prosecuted.

Scientists and engineers are searching for ways to reduce the quantity and improve the quality of wastewater treatment. Industries are seeking to comply with water quality criteria and are adopting best practice environmental management and cleaner production techniques. Local, State and Commonwealth Governments are encouraging individuals and companies to use water wisely through education programs, legislation and pricing.

Industries are implementing management strategies to improve water quality by conserving water, eliminating use of contaminants and reducing degradation by treating wastewaters effectively before discharge. Everyone can help to reduce the quantity and improve the quality of wastewater going to the sewage treatment plant.

Changes made to water that turn it into wastewater include: warming or cooling it, adding human wastes; adding oil, grease or fat; adding organic matter such as food wastes; and adding poisons such as pesticides, some organic compounds, synthetic chemicals and heavy metals.

Where does wastewater come from? What is wastewater treatment? What happens in a sewage treatment plant? Wastewater treatment occurs in four stages: 1—Primary treatment Removes solid matter. How is waste water managed? For example, industry can: avoid generating unnecessary wastewater, minimise the amount of water used, minimise the strength of contaminants, treat and re-use wastewater, use evaporation ponds, dispose of wastewater to the sewerage system with local government approval , and treat wastewater before discharge to waterways or the ocean.

Is wastewater treatment effective? Future directions Scientists and engineers are searching for ways to reduce the quantity and improve the quality of wastewater treatment. How can I help? Never connect stormwater drains to the sewerage system or sewerage drains to stormwater.

This is illegal! Stormwater drains take large amounts of water from roofs, buildings, land and paved areas after rain. Connecting toilets and other domestic waste drains to stormwater drains could result in wastewater flowing down open gutters.

This is harmful to the environment and a serious heath hazard. Compost your kitchen scraps Disposing of kitchen scraps via an in-sink style garbage disposal units can place additional loads on sewage treatment systems and add nitrogen and phosphorus into our waterways. Try composting at home to convert your kitchen scraps and garden clippings into compost to fertilise your plants and enrich your soil.

By composting kitchen scraps you can give nutrients to your garden, cut down on solid waste household rubbish , conserve water and reduce wastewater disposal water down the drain. Because wastewater treatment is expensive, composting saves rate payers' money too! Create less wastewater Conserve water by turning the tap off when brushing your teeth, taking shorter showers, fixing dripping taps, using the washing machine only when you have a full load and installing a dual-flush toilet and water-saving shower nozzle all help reduce the amount of wastewater entering the sewerage system.

Never put harmful substances down sinks, toilets or stormwater drains Substances including petrol, grease, oil, pesticides and herbicides, and solvents such as paint strippers should not be poured down sinks, toilets or stormwater drains. These substances are difficult to remove in the sewage treatment process and cause pollution problems in our local waterways.

Text description provided by the architects. The project consists of the volumetric and material definition for the new buildings to be realized in the Extension of the Sewage Treatment Plant of San Claudio , near Oviedo; New buildings whose position and function to perform within the Station are established by the Engineering and Hydraulics Project for water treatment.

Not only for sustainability but also for economic reasons. Transformation of municipal wastewater treatment plants from energy consumers into energy generators now couples the water and energy sectors together into a new game-changing industry. Substantial amounts of fresh water are consumed in modern society and all too often poorly treated wastewater is discharged into the environment. To counter these trends, modern digitalization offers a great degree of controllability in municipal wastewater treatment resulting in higher quality of treated water. To improve the reuse of water and reduce the discharge of industrial wastewater, a zero liquid discharge ZLD or a minimal liquid discharge MLD treatment system is often used. ZLD and MLD are ambitious wastewater management strategies that enable the plant or facility to recover most of its wastewater for reuse.

From people using water in kitchens and bathrooms in their homes and from commercial and industrial use. Nearly half the state's population, over 2 million people in 43 communities, send sewage to MWRA's treatment plants on the shores of Boston Harbor. Over 5, businesses and industries contribute wastewater as well. In addition, nearly half of the total flow in MWRA sewers is from rainy-weather street runoff and from below-ground cracks and faulty connections that allow groundwater into the system. Sewage travels through three different sets of pipes. Water that is used in a home or industry is flushed through a building's pipes until it reaches local sewers which are owned and operated by city and town sewer departments. These 5, miles of local sewers transport the wastewater into miles of MWRA interceptor sewers. The interceptor sewers, ranging from 8 inches to 11 feet in diameter, carry the region's wastewater to two MWRA treatment plants. Though most of the wastewater flows by gravity some low-lying areas require pumping.

HUBER Report

Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater or effluent may be reused or released to a sanitary sewer or to a surface water in the environment. Most industries produce some wastewater.

We recommend treatment processes that are suited to the nature of the effluents, we determine avenues of optimisation and deliver facility operation and maintenance based on best practices. We propose a custom offer which can be adapted to your production needs and enables you to benefit from the quality of a water treatment plant without the need to invest.

In some applications, more advanced treatment is required, known as quaternary water treatment. This stage deals with part per million to part per billion levels of contamination and often involves oxidation or fine filtration processes. Each of these stages tackles different pollutants, with water becoming cleaner as it moves through the phases. Different treatment stages or combinations are adopted dependent on the original quality of the water and its intended final use. During primary treatment, wastewater is temporarily held in a settling tank where heavier solids sink to the bottom while lighter solids float to the surface. Once settled, these materials are held back while the remaining liquid is discharged or moved through to the more rigorous secondary phase of wastewater treatment. These large tanks are also often equipped with mechanical scrapers that continually drive collected sludge in the base of the tank to a hopper which pumps it to sludge treatment facilities. Secondary treatment of wastewater works on a deeper level than primary and is designed to substantially degrade the biological content of the waste through aerobic biological processes. It is done in one of three ways:. Biofiltration uses sand filters, contact filters or trickling filters to ensure that any additional sediment is removed from the wastewater. Aeration is a lengthy process which increases oxygen saturation by introducing air to wastewater.

HOW DOES SEWAGE GET TO THE TREATMENT PLANTS? Water that is used in a home or industry is flushed through a building's pipes until it reaches local.


Wastewater characteristics and effluent quality parameters 1. At the same time, with population expanding at a high rate, the need for increased food production is apparent. The potential for irrigation to raise both agricultural productivity and the living standards of the rural poor has long been recognized. Irrigated agriculture occupies approximately 17 percent of the world's total arable land but the production from this land comprises about 34 percent of the world total. This potential is even more pronounced in arid areas, such as the Near East Region, where only 30 percent of the cultivated area is irrigated but it produces about 75 percent of the total agricultural production. In this same region, more than 50 percent of the food requirements are imported and the rate of increase in demand for food exceeds the rate of increase in agricultural production. Whenever good quality water is scarce, water of marginal quality will have to be considered for use in agriculture. Although there is no universal definition of 'marginal quality' water, for all practical purposes it can be defined as water that possesses certain characteristics which have the potential to cause problems when it is used for an intended purpose.

Water & wastewater treatment

Wastewater treatment operation and maintenance is a complex process - one that is essential for the successful treatment of wastewater before it is discharged into the environment. Industrial wastewater is a by-product of industrial processes, and is separate from domestic sources of wastewater.


The Evac MBR is a biological sewage treatment plant that offers advanced black and gray wastewater treatment solutions. It directly replaces traditional biological units, and with its membrane technology it easily fulfills all current and imminent treatment requirements. In some cases, effluent from the unit can even be recycled for specific uses.

Anglian Water is the largest water and wastewater company in England. Their pressure management system helps reduce water loss management costs and meet regulatory compliance.

Sewage treatment is the process of removing contaminants from municipal wastewater , containing mainly household sewage plus some industrial wastewater. Physical, chemical, and biological processes are used to remove contaminants and produce treated wastewater or treated effluent that is safe enough for release into the environment. A by-product of sewage treatment is a semi-solid waste or slurry, called sewage sludge.
