Used water, whether from washing dishes, bathing, or other domestic or commercial processes such as irrigation in agriculture and farming, is known as ‘wastewater’. Due to increasing population, the management, handling, and safe disposal of it have become a global concern for governments and environmental organisations. This concern especially extends to commercial businesses producing liquid waste on a large scale. This often has high levels of harmful contaminants, which require purification using industrial effluent treatment plant and systems. Different industries produce effluent of varying degrees in terms of the types of contaminants and the amount; some produce larger volumes than others. Wastewater generated from industrial processes needs proper treatment methods, designed to address the needs of each business according to the type of contaminants. Failure to do so can result in non-compliance with environmental standards, increasing the risk of hefty fines and causing harm to the ecosystem. Find out which industries generate the most significant amount of effluent and the requirements set to treat it. Industrial Wastewater Discharge Compliance in the UK In the UK, the Environmental Agency regulates all activities pertaining to the safety of the environment, and this includes the management of wastewater by industries. The agency sets the compliance standards and regulations that commercial businesses generating liquid waste need to adhere to. Notable requirements of the standards include: Specifying monitoring and treatment requirements for liquid waste generators and industries discharging biodegradable liquid waste. Selection of appropriate wastewater treatment methods to meet the required purity levels that will not compromise the quality of receiving water bodies (e.g., streams, estuaries, wetlands, etc.). Employing secondary and advanced treatment methods. Outlining requirements when discharging in sensitive areas. Some of the industries that generate significant amounts of wastewater are: Manufacturing Companies In the UK, the manufacturing sector is populated by companies in oil and gas extraction, mining, electricity, water, and waste management. Wastewater generated by these companies contains toxic contaminants such as heavy metals, biological and chemical impurities, dissolved salts, and hydrocarbons. Manufacturing companies invest in different purification technologies and methods, using industrial effluent treatment plant right at the source. Car Washing and De-icing equipment Car washing and de-icing equipment both generate a substantial amount of effluent, which requires proper management. De-icing equipment includes trucks, sprayers, booms, etc., essential for the removal of snow or frost from aircraft, roads, sidewalks, and other transportation infrastructure. Liquid waste contains de-icing fluids and chemicals, such as glycol-based solutions or potassium acetate. On the other hand, liquid waste from car washing businesses contains oils, grease, and soap and requires appropriate management and treatment methods. Food processing The activities in food processing warrant the installation of industrial effluent treatment plant, due to the generation of high volumes of wastewater that has excessive levels of non-conforming contaminants. Some of the activities include sterilisation, blanching, packaging, canning, etc., of which the result is high salinity and acidity, and pesticides, among other contaminants. Proper management of liquid waste from this industry at the source is absolutely necessary. Desalination This is a crucial process in water and wastewater treatment, which involves the removal of salts and other minerals. At the end of the process, the liquid concentrated with salts requires proper management to prevent leakage into the environment. In addition, further treatment may be needed to recover the salts and minerals, and reduce excessive levels of harmful contaminants before disposal, in turn increasing the volume of liquid waste. The design and installation of appropriate industrial effluent treatment plant is not only invaluable for the profitability of the business, but also for its ability to operate lawfully under the regulations of the Environmental Agency. Adherence to required standards guarantees better wastewater management and protection of the environment to maintain the quality of receiving water bodies. For these reasons, it is always best to consult a reputable and professional company for the implementation of the most suitable and effective wastewater treatment systems.
