All options are classed as remedial measures; compensatory factors; surveillance. Corrective measures for dealing with problems found on your operation and improve the rating to (3 or even 4). The compensatory factors are alternatives that will adequately address the concerns, but will not change the notes in the EFP work. Monitoring is only under specific circumstances and in accordance with the methods described in this form.
At the request of the Farm Environmental Coalition of Ontario, comprising the Federation of Agriculture Ontario, the Christian Farmers Federation of Ontario, AGCare and Ontario Farm Animal Council, the following persons participated in the preparation the fact sheet No. 7:

Quantity of wastewater
Situation - problem: 7-1 Efficient water
By consuming less water in the house, it decreases the amount of wastewater that the plant must treat septic. It follows several vantages: lengthening the life of the installation, less frequent emptying of the pit and lower risk of contamination of surface and groundwater. Without forgetting that reduces pumping water into the wells and the energy bill.
Quality of wastewater
The rejection of solid waste in the sewage network, especially when using a shredder waste under the kitchen sink, greatly increases the burden on solids sent in the septic installation. The tank must be drained more often and scope purification receives a greater quantity of organic materials to "digest". This surcharge may entail the failure of the facility and, therefore, a high risk of contamination of surface water and groundwater.

 Illustrate the system performance BIONEST advanced secondary treatment, sampling an actual installation over a period of twelve months has been made. The installation has been studied wastewater from two units of two bedrooms each. The study included analysis of several parameters whose DBO5C and MES, sixteen samples taken from the tributary and the effluent.
The effluent obtained with the system features physicochemical remarkable: less than 4.4 mg / L in DBO5C and less than 3.5 mg / L for MES, while the average content of fecal coli form east of 1 670 UFC/100mL. These results represent average yields disposal of 98%, 96% and 99% for DBO5C, MES and fecal coli form, respectively. Other parameters such as COD, turbidity and total nitrogen have also presented a significant decrease.
During sampling, flow rates and charges at the entrance were higher than normal conditions, but these conditions have shown that the system BIONEST can easily meet all standards of rejection, even when surcharges. It has been demonstrated that the system of sewage treatment BIONEST rejects effluent quality far exceeds the requirements of Regulation Q-2r.8. Concentrations of DBO5C MES and the effluent was also 3 to 4 times lower than those required. Concentrations of fecal coli form were, however, 30 times lower than required.

The treatment system BIONEST uses a biological process using a microbial culture, set on a medium non-biodegradable, with alternating purification processes aerobic and anaerobic.
This technology is distinguished by its patented media that allows an effective adhesion of the bacterial population depolluante and provides greater surface active reactions nitrification / denitrification.
The effluent at the reactor outlet biological technology BIONEST presents a much higher quality government standards, and in all seasons.
HIGHLIGHTS
Technology
* Media with a very active and surface texture promoting rapid growth of microorganisms
* Water resistant to shocks, changes in temperature and changes in charge of the tributary
Environment
* Media non-toxic and non-biodegradable
* Reduction of more than 99% of faecal coliform
* Removal of more than 98% of the BOD5 and more than 96% of MES
Economy
* Media synthetic among the least expensive per square meter on the market
* Minimum Maintenance Cost
* Cost of operation modest
OBJECTIVES OF THE PROJECT / PHASES
Since 1997, the objective of Bionest Technologies Inc. is to develop and market a system of quality higher than the conventional options for the treatment of sewage while economic and require little maintenance.
Advised by experts at the University of Guelph in Ontario (site of Alfred), Bionest Technology inc. has developed its system under various conditions. The draft of a system adapted to a residence of four bedrooms was then subjected to the evaluation of the Committee on new technologies wastewater treatment. This committee is composed of the Ministry of Municipal Affairs, Sports and Recreation and the Ministry of Environment Quebec (MENV). |

The city of Alma has a system of worm gear to treat its sewage. It has long been a break-in period to allow the sand to separate sewage.Sewage is transported in ponds aerated and treated once discharged into the river Early Discharge.
The introduction of the system vis endless amounts to $ 1 400 000. Initially, construction costs ponds were valued at $ 18 000 000, now they total $ 41 400 000. They are divided into the following proportions: 90% funded by the Government of Quebec (37 260 $ 000) and 10% funded by City of Alma (4 140 00 $).
System aerated ponds St-Bruno
Wastewater from the municipality of Saint-Bruno and two large industries were dumped into the river Bédard. To eliminate the pollution load, the municipality of San Bruno has a system of wastewater treatment ponds 4 ventilated. All equipment have been designed to cope with the peak period of August caused by the freezing plant blueberries, which runs at full speed.
The residue of the production of cheese (whey) from the Fromagerie Saint-Laurent are not all treated with the treatment of domestic sewage in the municipality of Saint-Bruno. Indeed, much of this little milk is delivered to the plant Lactel Chambord where it is processed into powder for animal feed. Lactel deals between 8 and 9 million litres of whey per year and the plant has a 5-year contract with the Fromagerie St. Lawrence.
The work was done at a cost of $ 2 000 000, construction was originally scheduled for 1 500 000 $ therefore with a surplus of $ 500 000 compared to the project starting in order to include private industries.

Background
Wastewater treatment facilities, such as municipal, agricultural or industrial wastewater treatment facilities, commonly utilize aeration techniques in order to treat the wastewater. Aeration of the wastewater has been found to reduce or eliminate contaminants found in the wastewater by increasing the oxygen available to microorganisms which break down contaminants during a biological process. Such techniques have been found to reduce the BOD (biochemical oxygen demand) and / or ammonia levels found in wastewater. However, there is an ongoing need to provide more efficient ways of treating wastewater.
Summary
The disclosure is directed to apparatus, structures, systems and methods for treating wastewater,
Accordingly, one illustrative embodiment is an apparatus for treating wastewater at a wastewater treatment facility. The apparatus includes a microorganism clad structure positioned in a body of wastewater such that the microorganism clad structure is at least partially submerged in the body of wastewater. The apparatus also includes an aeration device, such as a propeller-type surface mounted aeration device, supplying a horizontal flow of oxygenated water to the microorganisms attached to the microorganism clad structure such that the microorganisms may carry out a biological process.
Another illustrative embodiment is a wastewater treatment system including a wastewater containment reservoir containing a body of wastewater, A baffled structure including a plurality of microorganism clad sheets of material are positioned in the wastewater containment reservoir such that the plurality of microorganism clad sheets are at least partially submerged in the body of wastewater. An aeration device, such as a propeller-type surface mounted aeration device is positioned in the wastewater containment reservoir in proximity to the baffled structure. The aeration device provides an oxygenated flow of wastewater past the microorganisms such that the microorganisms may carry out a biological process in the body of wastewater.
An illustrative method of treating wastewater includes the steps of submerging a microorganism structure clad in a body of wastewater such that at least a portion of the microorganism clad structure is immersed in the body of wastewater. Oxygen may be injected into the body of wastewater with an aeration device, creating a high velocity jet fluid in the body of wastewater, thereby providing a horizontal flow of oxygenated water and / or nutrients past the microorganism clad structure to provide a favorable environment to carry out a biological process.
