In recent years, with the rapid development of industry, the amount and types of wastewater have also been increasing, and the pollution of water bodies has become increasingly severe, which has seriously threatened human safety and health. In order to establish a good ecological environment, industrial wastewater treatment is particularly important.

The serious contradiction between water supply and demand is mainly manifested in the shortage of water resources and the continuous increase in water demand. In this context, the recycling of water resources is the main way to solve this contradiction.

With the rapid development of industry, industrial wastewater continues to increase, and environmental pollution is becoming more and more serious. Monitoring is one of the important links in the control and treatment of environmental pollution. The pH value, electrical conductivity, COD (chemical oxygen demand), BOD (biochemical Oxygen demand), DO (dissolved oxygen), TOC (total organic carbon), TOD (total oxygen demand), toxic heavy metals such as lead, cadmium, zinc and cyanide, arsenide and fluoride, etc. are all required items.

In Germany, industrial wastewater treatment must comply with the strict regulations of the "Wastewater Regulations" (Abwasserverordnung). Improper and inadequate treatment may result in the closure of the entire treatment plant until the defect is corrected.

Treating industrial wastewater is much more than just complying with environmental regulations. High water consumption factories reduce raw material costs by treating and reusing wastewater.

Especially for organic wastewater treatment, accurate measurement of pH, oxidation-reduction potential (ORP) and dissolved oxygen is essential to ensure optimal metabolism of bacteria used for purification.

Monitor pH, ORP and oxygen to achieve environmentally harmless wastewater treatment

Unlike service water for private households, industrial wastewater is contaminated by substances that are difficult to decompose. Depending on the industry, they may be heavy metals, grease, grease, alkaline substances, or like the paper and soap industries, organic substances can only be neutralized or separated through great efforts. In addition to mechanical filtration methods, heat treatment and microorganisms are also used to purify it.

PH measurement to protect plants and bacteria

According to the degree of pollution, organic polluted wastewater undergoes different purification processes, including flocculation and sedimentation. During the flocculation process, the dissolved harmful substances are condensed into flakes, which can be filtered. The goal of precipitation is to recombine harmful substances into heavier compounds before drifting down to the bottom. If these treated wastewater cannot be classified as harmless, bacteria will convert the remaining pollutants into flammable or recyclable biomass in the aeration tank.

Industrial water or clean water from food and beverage production or fermentation processes has a highly variable pH, depending on the application. Since low pH values can damage plant components or kill bacterial cultures, recording the pH value in the feed line is a timely countermeasure. Too high or low pH value can be neutralized by adding chemicals, or interrupting the wastewater entering the clarifier when necessary.

Underwater measurement of ventilation control

ORP is an important parameter for efficient ventilation in aeration tanks. Combined with other process variables, it provides useful information about the ratio of oxygen content to bacterial activity. As a summation parameter, ORP does not indicate the absolute amount of a substance. Instead, it can continuously measure and observe changes in concentration over time. Comparing the concentration trend with other values can provide a basis for controlling the ventilation of the storage tank, so as to achieve the maximum efficiency in the aerobic and anaerobic metabolic stages. Experience has shown that the most useful measurement results come from the upper 25% of the water in the tank. The measuring electrode must be immersed in water to reach this level.
