Control of industrial and urban discharges

Discharge Control

Control of discharges

Uncontrolled industrial and urban discharges are a serious environmental problem affecting every country in the world. Water, air and soil pollution are the direct result of uncontrolled wastewater discharges.

Controlling these discharges is an important part of sustainable development and a shared responsibility between the public and private sector. 

In this entry, we will discuss how to control discharges to reduce pollution, improve the environment and comply with current regulations.

Discharge of waste water

First things first, what exactly is wastewater?

Wastewater is any type of water affected by human activity, and which requires specific treatments to be purified and usable. 

These wastewaters are those that have been used in urban and domestic environments, or in industries and livestock farming. In many regions of the world, the uncontrolled discharge of this wastewater results in a high level of pollution. pollutants discharged into the sea which have a negative impact on the environment and public health.

Types of waste water

Wastewater can be classified in different ways, either according to the amount or type of chemical it contains; according to its bacteriological characteristics; or according to its origin. The latter is the most common. Its three types are:

  • Industrial waste water: these are industrial discharges which have been spread from an industrial site, which accumulate spills and liquids from factories, or which come from farms such as agricultural discharges
  • Domestic wastewater: originating in the dwelling both from human metabolism and from household activities.
  • Urban wastewater: This is a mixture of domestic and industrial wastewater. urban waste which includes stormwater runoff that is generally conveyed through sewerage systems.

Control of industrial and urban discharges

The waste water discharge to the hydraulic public domain and to the coastline must comply with the regulations of the autonomous community on waste discharges, and must be authorised by the same. 

Regulation of discharges 

In Spain, discharges of waste water without prior authorisation are prohibited.. This is subject to a number of conditions and the payment of a fee.

This authorisation lays down the conditions under which the discharge must be carried out and the necessary treatment or disposal facilities. 

According to the Department of Sustainability, Environment and Blue Economy of the Junta de Andalucía, "discharge operators shall carry out discharge monitoring and control programmes". The purpose of which is to locate the presence of sources of integrated pollutants in the waste water. 

This is where the installation of a continuous monitoring system comes into play, allowing us to react in time and avoid any sanctions.

Water Biosense in discharge control

Innovative equipment technology Water Biosense provide a system for early detection and continuous and automatic monitoring of agents of interest in water, including microbiological contaminants in wastewater, enabling quality monitoring and discharge control.

The technical characteristics of Water biosense in terms of sensitivity, automaticity, programmable, remote via IoT and robustness, allow it to adapt to inhospitable waters. All this without having to send a technician to take samples, send them to the laboratory and consequently wait and incur additional costs.

Water Biosense is a complementary solution to traditional laboratory analysis, without human intervention, which records and reports biochemical parameters tailored to each need in real time.
