Aeration. A technique by which air is introduced into a liquid; bubbles and aero are generated and dissolved gases released. For example, water aerated by passing through a showerhead will release dissolved radon gas. ACTIVATED CARBON: A material made from burnt wood, which is used to remove organic solutes, such as pesticides, and some inorganic solutes, such as chlorine, from water. Dissolved organic solutes are removed from the water by absorption onto activated carbon. The activated carbon must be periodically replaced when it becomes saturated and unable to adsorb any more solute. Activated carbon is not effective in removing heavy metals, such as lead.
Aeration. Contractor shall aerate once per year or as determined by work order, typically in Spring.
Aeration a. All turf areas shall be aerated once per year between October 1st and October 31st immediately prior to the scheduled fertilization in October.
Aeration. Section 10.1 In case of violation of any of The terms of this agreement by any of the parties notice in wrung must be given to the party alleged to brave violated the agreement and such party must be given reasonable time to correct any of The violation attributed to it.
Aeration. All sod areas will be aerated in the spring and fall. Prior to aeration, the Consultant shall flag all sprinkler heads and valve boxes to prevent damage. Plugs shall be left on turf to assist in breaking down thatch. Additionally, Consultant shall aerate selective areas near the end of the growing season. Selective areas shall include south facing slopes, heavy use areas and areas of unusually tight soil.
Aeration. Aeration is necessary for thermo-phallic aerobic composting in order to obtain the rapid decomposition, fast decomposition that is characteristic of the process and also is useful in reducing high initial moisture content in composting materials. Several different aeration techniques have been utilized with varying degrees of success. Turning the material is the most common method of aeration when composting is done in stacks. Hand turning of the compost in piles or pits is most commonly used for small villages and farms. Mechanical turning is most economical in large municipal installations. The most important consideration in turning compost apart from aeration is to ensure that the material on the outside of the pile is turned into the Detailed Project Report on Solid Waste Management for Varanasi City Detailed Project Report on Solid Waste Management for Varanasi City centre, when it will be subjected to high temperature. In hand turning with forks, this can be readily accomplished e.g. piles or windrows on top of the ground are simply reconstructed with the materials from the outer layers placed on the inside of the new piles. In case of composting in pits, or trenches, the material can be moved from one pit to another for aeration or if a little space is left at the end of the pit at the initial filling, the material can be turned within the pit. The loss of volume of the material during the stabilization period will facilitate turning within the pit. Mechanical equipment for turning windrows in large composting operation has been developed extensively as a result of the increased interest in composting as a method of refuse disposal. The important criterion for the high degree of aeration is for the avoidance of anaerobic conditions, maintenance of high temperature and the control of flies.
Aeration. 1) One core aeration is included under this agreement. Additional aerations can be performed upon request and shall be billed upon completion.
Aeration. All turf areas are to be aerated according to the frequencies listed on Section II.E, “City Facilities and Service Levels.” Core size shall be at least 3/4" in diameter and 3" - 4" in depth and aerated in two directions. One athletic field, selected by the City, shall receive deep-tine aeration, followed by a top dressing, once per year. Cores do not need to be removed but should be mowed over. City staff shall flag/mark irrigation system heads, valve boxes, and quick couplers. Contractor shall notify the City Representative of aeration scheduling a minimum of two days prior to start of aeration. Contractor is responsible for repairing any damage caused by aeration equipment. This includes, but is not limited to, irrigation boxes, quick couplers, sprinkler heads, valves, etc. For small lawn areas, the Contractor shall be responsible for providing a walk-behind mechanical, camdriven core-tined aerator (Xxxx Xxxxxxxxxx or Lawnaire or City-approved equivalent).
Aeration. 2.2.3.1 As needed to maintain standard.
Aeration. Aeration must be performed annually in 1 of the following months: April, May, September or October. Plugs from the aeration should remain on the lawn to break down into the soil OVERSEEDING Over seeding must be performed annually in 1 of the following months; April, May, September or October according to the detailed over seeding instructions below: Spread topsoil over lawn area to a depth of 1 inch and rake into the lawn. Broadcast a seed mixture high in fescue and low in Kentucky Blue grass seed content (20 % or less) using standard seed spreading equipment. Water lightly (less than 10 minutes per area) for 10 days until seeds germinate. If aerating in the same season as over seeding, aerate first and over seed 2 to 3 weeks later.
