What are the dangers of air stripping in wastewater treatment plants?
This can cause respiratory and gastrointestinal exposure. Some organisms pass directly into the bloodstream. Experts at Cornell University report that though air-stripping occurs during aeration and other processes, it occurs less at wastewater treatment plants because the particles tend to attach to solids rather than water 1.

By cutting down environmental pollution, water treatment helps to reduce health hazards that emanate from a polluted environment.
Why is water treatment important?
Wastewater treatment ensures people will be able to enjoy water sports without having to worry about water pollution. Water from treatment plants can also be supplied to areas experiencing drought. Thus water treatment is an eco-friendly process that helps in reducing water wastage by recycling water that would otherwise have been deemed to be unsanitary and end up being disposed.
What is the biomass produced from sludge?
The biomass that is produced from the sludge phase is decanted and dried: this turns it into organic fertilizer . The current trend in the world is to use less of chemical (inorganic) fertilizer for farming.

As the quantity of organic matter is bigger, the activity of the organisms that feed on it increases.
What is the function of water treatment plants?
One of the functions of water-treatment plants is in fact to lower the concentration of these compounds to acceptable levels ," said Aristi. However, the components of the other group are toxic pollutants, ones that harm river organisms in one way or another. In the research they concentrated on drugs dissolved in the water.
How do pollutants affect river organisms?
They have noticed the influence of assimilable compounds mainly in respiration, in other words, in the processing of organic matter. Aristi explains it thus: "When the concentration of assimilable compounds increases, respiration also increases. Respiration is much greater at the place where the effluent from the water-treatment plants is incorporated than in the upriver stretches, and when it heads downriver, the concentration of assimilable compounds gradually decreases and with it respiration ."
What are the two groups of compounds in the effluent of water treatment plants?
The compounds in the effluent of water-treatment plants could be divided into two groups in terms of how they affect the river ecosystem: the ones that boost the activity of the organisms, and the ones that harm or hamper it. The first group comprises organic matter and nutrients, the so-called assimilable ones.

Why do we need tank covers in wastewater treatment plants?
Through the use of tank covers, it can help stop hydrogen sulfide and methane from being released into the air. Covers also help keep debris like leaves, dust, and tree pollen from getting into wastewater basins.
What to do if you don't have a cover on your water tank?
If water costs are low, they’re less likely to complain. Covers are the most cost-effective solution in a wastewater treatment plant. If you don’t have covers on your tanks, you should consider them. Talk to Lakeside Equipment about equipment upgrades that help reduce odors and lower your operating costs.
How to neutralize plant smells?
That lowers operating costs. Deodorizing misting systems throughout the plant help neutralize the smells. Another option is to start adding chemicals that react with the compounds that cause the odors. Adding an air purifying system that captures the air, filters it through biofilters or carbon filters is also helpful.
