Disposal of waste water from both domestic (household) and industrial activities into water bodies can cause environmental pollution if the quality of the wastewater does not meet the waste quality standards. For example, let's look at the City of Jakarta. Jakarta is a very dense capital city so that the location of the septic tank, cubluk (balong), and garbage disposal are close to groundwater sources. There is a study which states that 285 samples from 636 sample points of groundwater sources have been contaminated by coli bacteria. Chemically, 75% of these sources do not meet the drinking water quality standards whose parameters are assessed from the elements of nitrate, nitrite, iron, and manganese.


What about industrial wastewater? In industrial activities, wastewater will contain substances/contaminants produced from residual raw materials, residual solvents or additives, wasted or failed products, washing and rinsing of equipment, blowdown of several equipment such as boiler boilers and cooling water systems, as well as sanitary wastes. In order to meet quality standards, industry must apply the principles of careful and integrated waste control both in the production process (in-pipe pollution prevention) and after the production process (end-pipe pollution prevention). Control in the production process aims to minimize the volume of waste generated, as well as the concentration and toxicity of the contaminants. While control after the production process is intended to reduce the levels of pollutant materials so that in the end the water meets the quality standards that have been set.


Liquid waste treatment is to keep the water that comes out clean by removing the pollutants present in the wastewater, or by decomposing the pollutants in the wastewater so that the properties of these pollutants are lost. Before planning and implementing wastewater treatment plant, the industry must understand waste management management such as establishing policies and procedures for waste management and treatment, policies for waste minimization before generating and treating waste, assigning personnel who are responsible for implementing waste management and treatment procedures and conducting evaluations.


Implementation of waste management and treatment procedures. Some things that must be considered in waste treatment include

The production process in the industry. The quality and quantity of liquid waste produced and its changes.

Geographical environmental conditions, water conditions around the liquid waste disposal area.


There are several ways of treating liquid waste that can be done in industry, namely:


Physical waste treatment


By separating impurity materials that are visible and large enough by using filtration or physical treatment. The process includes sedimentation, floatation, absorption, and screening;

Chemical waste treatment

The addition of chemicals to precipitate / separate / remove impurities in the liquid waste. The process includes coagulation, oxidation, ion exchange, degradation, ozonation, and others.

Biological waste treatment

Using live biota or microbes to decompose pollutants in liquid waste. The process includes aerobic, anaerobic, facultative.
