More than you wanted to know about your Oldham brand Aeration Sewage Treatment System! Oldham brand aeration sewage treatment systems have an initial break-in period of six-to-eight weeks, during which time bacteria establish themselves in the unit. The development of these biological colonies occur naturally with the addition of sanitary wastes, so we recommend you use all your plumbing facilities in a normal manner from initial start-up. You may notice a septic odor during this initial break in period, this should clear up within 2-3 weeks. You may also notice a tendency for the unit to foam from laundry wastes during this period. This is normal and it should cease by the sixth week. You can help by using only moderate amounts of low-sudsing biodegradable detergents. An Oldham brand aeration sewage treatment system, operating properly and well maintained will NOT smell bad. The smell should be similar to what it smells like after a farmer plows their field, a kind of musty-earthy smell. The color in the aeration chamber should be chocolate brown. If a system smells bad, it is probably not operating long enough (or not at all). See below for how long it should run. Sewage treatment is a multi-stage process to renovate wastewater before it reenters a body of water. The goal is to reduce or remove organic matter, solids, nutrients, disease-causing organisms and other pollutants from wastewater.

Be sure to conserve water as much as possible, for example use low flow faucet aerators and low flow shower heads. When (or if) you need to replace a toilet, replace it with a low flow model. If you have a whirlpool bathtub, try not to use it very often, since these tubs can use from 40 to 100 gallons at a time, this is too much water for the system to handle at once, when you drain it, try to drain it in stages with at least an hour or so between stages. When you do laundry, space it out through the week, laundry should not be done all in one day. When possible, allow an hour or so, between loads. Never do more than 2-3 loads of laundry in one day. This can "flush" the system, resulting in the sewage not being treated. For aeration systems, we recommend using powdered laundry detergents, since they do not foam up as much. If you’re in the market for a new washing machine, you should consider a high efficiency models. Most conventional washers use about 40 gallons per load, where front loaders use about 25 gallons or less per load.

Oldham authorized service provider Steve Hayner 937-644-1625 Oldham authorized service provider [email protected] 937-644-9775 The Oldham treatment process is accomplished in 4 steps. The Oldham Sewage Treatment System utilizes the extended aeration process, which treats sewage by stabilization of organic matter. This is achieved by thoroughly mixing fresh and treated sewage in an oxygen-saturated environment combined with continuously controlled sludge return. Extended aeration of the recirculating solids produces a clear odorless effluent. Pre Treatment (1st Compartment) The first compartment, 400 gallons capacity, receives the raw sewage from the house. All foreign matter and heavier solids settle in this compartment. The solids that will decompose in water (comprising more than 99% of the solids) together with the liquid waste, then pass through a vitrified elbow into the second compartment. Aeration Treatment (2nd Compartment) Aeration treatment is a biological treatment process to remove dissolved organic matter from wastewater. In the second compartment, air, which is supplied by a positive displacement type pump located in a riser on top of the tank, is discharged into the contents of the compartment near the inlet wall and near the bottom of the tank. The discharge of air at this point causes the liquid in the compartment to circulate or roll with sufficient force that all of the solids in the sewage are maintained in suspension in the liquid. Sewage microorganisms or "bugs" eat organic matter from sewage as their food supply. Just like fish in an aquarium need air, the "bugs" in an aeration system need air also. As the bugs eat organic matter and nutrients from the wastewater they grow in size and number. Oxygen in the solution creates an environment favorable to the growth of aerobic bacteria. These microscopic organisms digest the solids in the sewage within the period of 24 hours. The capacity of this compartment is 600 gallons, more than the daily treatment capacity of the system. The average sewage flow from an individual residence is 400 gallons per day. Backwash water containing salt from water softener should by-pass waste water systems. Clarifier Chamber (3rd Compartment) The third component is the clarifier. When the contents of the aeration compartment enter the clarifier, the treated solids, no longer subjected to the rapid circulation of the aeration compartment, settle to the bottom of the clarifier and return to the aeration compartment by gravity through a slot, where they are further digested. It is important this opening be kept clear; regular pumping of the system does this. The lighter solids, which will float, are returned to the aeration compartment by means of a skimming device located at the surface of the liquid. Clear liquid is discharged from the clarifier form a point 2” below the surface of the liquid, through a vitrified elbow, and then carried to the point of discharge through the effluent pipe. Ground water from basement drain tiles and storm water must not be discharged into the system, as it will create a hydraulic overload, which will destroy the aerobic digestion process. Any discharge of wastewater in excess of the rated capacity should also be avoided. Rev. 6/26/2014 2 of 4 Final Treatment There may be a filter following the aeration system. Many of these filters can and should be backwashed or cleaned every time the system is pumped out. There are many types of filters, requiring different types of care. Contact your Service Provider or your local Health Department if you have any questions. Final treatment focuses on removal of disease- causing organisms from wastewater. Motor & Timer To conform to the testing procedures, under which all individual residential aerated sewage treatment systems are tested, sufficient air for the aerobic digestion process, and circulation of the contents of the aeration compartment, is supplied by a motor and blower unit which delivers 14 cubic feet of air per minute at 2 pounds pressure. To properly treat the wastewater of an average household the ½ horsepower motor will consume 85 to 90 kilowatts of electricity per month. The motor is controlled by a timer and is set to operate the necessary length of time (see below) to properly treat the sewage. This operating time will vary depending upon the amount of sewage to be treated each day. An undersupply of oxygen retards the aerobic digestion process and will result in a septic condition, which will cause an offensive odor. An oversupply of oxygen will result in too much aerobic digestion and the solids will become too light to settle and will be discharged with the effluent. Therefore, it is necessary to maintain the correct amount of oxygen in the contents of the aeration compartment. The proper oxygen content can be readily determined by noting the color of the contents, which should be a chocolate brown. Different timers allow you to set the time in different ways, be sure the timer is set so the system is never off more than 4 hours at a time.
