This tent seals off the home so that insect killing gases can then be pumped into the tented area, killing any termites inside. Of course, they can also damage or kill any houseplants inside, so removing these plants prior to tenting is important.
Why does air stripping occur less at wastewater treatment plants?
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.
What are the effects of inhaled organisms?
The effects of inhaled organisms vary from upper respiratory irritation accompanied by eye irritation to depression, central nervous system damage and severe systemic poisoning. Plant workers are often the first affected. If they realize they've been affected, they're able to alert managers to correct the problem.
What is an airborne hazard?
Airborne Hazards. Chemicals from wastewater treatment facilities become airborne when they're air-stripped. Air-stripping occurs when organisms, chemicals or particles in water find their way into air, where they can subsequently be inhaled.
Can cockroaches live in wastewater?
Housefli es, as well as other pests such as cockroaches, can also present a health hazard for those living near wastewater treatment facilities. Flies land on the food they eat to taste it, and raw sewage attracts houseflies.

Why do wastewater treatment plants need to seal the source of odors?
Treatment plants value their employees and should make efforts to improve their working environment by better controlling odors. To prevent diffusion of odor vapors, many wastewater treatment plants choose to seal the source of odors - whether that’s a tank, basin, or lagoon - with an industrial-grade cover.
Why cover up a tank?
Covers not only reduce odor emissions but also help contain harmful greenhouse gases and minimize evaporation so that less water and chemicals need to be used in the wastewater treatment process. Covering a tank or lagoon to control odors is a rare example of when covering up a problem makes perfect sense.
What are the factors to consider when selecting an odor control cover solution?
However, there are some important factors to consider when selecting an odor control cover solution, including: Airtightness: Typically, the objective is to have a cover that is sufficiently airtight so that foul air is reliably captured and does not escape through leak points.
Why does wastewater have an odor?
Due to its low solubility in wastewater, it is released into the atmosphere, producing an offensive odor. Amines and mercaptans are two other odor-causing offenders at treatment plants. These organic compounds contain sulfur or nitrogen, producing odors that are detectable by the human nose at extremely low concentrations.

What is crop type?
The crop type (see below) Possibly seasonal or other changes in surrounding surface runoff and groundwater, independent of the individual septic system but affecting its performance and thus its level of treatment of the sewage. Soil types affect how the septic system behaves and how it affects nearby plants of any kind.

Can pathogens travel to a septic system?
In that case pathogens may be released to the general environment and might travel any distance from the septic field. Root crops such as carrots or potatoes which develop in the soil are likely to pick up pathogens from effluent in the soil over, next to, or downhill from drainfield trenches or galleys.
Does biomat work in septic systems?
The effectiveness with which the soil biomat is treating pathogens in septic effluent, the ability of the soil to filter effluent, the chemicals or salts entering the septic system, and the type of plants placed over or near the system are some of the factors that lead to answers to these questions.
