Effective commercial wastewater treatment for shopping centres

Shopping centres make pretty successful businesses. They attract a hoard of customers who want to browse through a variety of shops, products and services – all under one roof. But, as its owner or manager, you know there are a heap of issues you have to look after daily, one of them being how to treat wastewater effectively.

In this blog post, we are going to take a closer look at the steps involved in treating wastewater in a shopping centre. We will explore the techniques used and why they are vital in keeping your shopping centre compliant with regulations and avoiding costly penalties.

What makes undertaking commercial wastewater treatments necessary for UK shopping centres?

The many types of businesses that operate in a shopping centre, like retail shops, takeaways, cafes, supermarkets and repair service providers, can make dealing with wastewater rather tricky. Each of these businesses will create their own wastewater issues which can include varying levels of Dissolved Solids (DS), Suspended Solids (SS), Fats, Oils and Grease (FOGs), and other contaminants.

For instance, restaurants can produce a lot of wastewater per meal, high in FOGs, proteins, salt, and sugar. These pollutants, in turn, affect the pH, Biological Oxygen Demand (BOD), and Chemical Oxygen Demand (COD) of the wastewater.

Different businesses generate sewage at different rates and with varying levels of impurities. Wastewater flowing in the shopping centres can be unpredictable, particularly during busy and quiet periods.

The amount of water consumed and wastewater produced can also vary due to shared facilities. This can result in not meeting the discharge limits set by environmental regulations. In the UK, it is the responsibility of the owners and managers of such establishments, known as “waste holders,” to treat and dispose of sewage and wastewater properly.

Local agencies also issue licences that include specific discharge limits. Failure to comply with these regulations can result in hefty fines or jail time. It is, therefore, crucial to have an efficient commercial wastewater treatment system in place for the shopping centres to avoid any legal issues.

What methods are used to treat wastewater at UK shopping centres?

The techniques implemented depend on the amount produced, the types of impurities present and the kinds of businesses that operate in the shopping centres.

With commercial wastewater often containing chemicals, FOGs, and other pollutants, it is critical to use custom solutions that actually work for minimising contamination within wastewater. Some of the common ones include:

1. Advanced oxidation technology

This method uses electricity to treat wastewater at shopping centres. Electrocoagulation and Electro-oxidation are used to remove organic matter more quickly and effectively without using chemicals. This method reduces contamination to extremely low levels, enables the standard multi-media filters to last longer, and makes the water reusable.

2. Chemical methods

As the name suggests, chemical methods involve using chemicals such as chlorine, hydrogen peroxide, and alum to treat wastewater. These chemicals react with impurities present in the water and break them down into simpler forms.

3. Biological methods

These use microorganisms to break down impurities present in the water at the source. BiOWiSH® solutions, for instance, made from natural products, work at the source to create positive changes in the microbiome and rebuild beneficial microbes that start working immediately.

4. Membrane filtration and/or reverse osmosis

This method uses a semipermeable membrane to filter out impurities from the water. The water is forced through the membrane, and impurities are trapped on one side, while clean water is collected on the other side. This technique is similar to reverse osmosis, which uses a high-pressure pump to force water through a semipermeable membrane that removes impurities like salts, ions, and dissolved solids.

5. Dissolved Air Flotation (DAF)

The DAF system is a smart way for shopping centres to handle wastewater. It uses tiny bubbles to remove pollutants from the water, which attach to Suspended Solids (SS) and FOGs and float to the surface.

This causes the floating solids to become denser and form sludge, which is then removed by mechanical scrapers. Some DAF systems are self-cleaning and automated, making them a convenient option for shopping centres.

It is important to note that the most appropriate commercial wastewater treatment method will depend on the specific needs of the shopping centre, such as the type of impurities present in the water and the volume of wastewater produced.

It is best to consult a specialist in wastewater treatment to determine the best solution for your mall.
